[2] Processor
========================================================================
[2-1] What is a PowerPC?
A PowerPC is a microprocessor designed to meet a standard which was
jointly designed by Motorola, IBM, and Apple. The PowerPC standard
specifies a common instruction set architecture (ISA), allowing anyone
to design and fabricate PowerPC processors, which will run the same
code. The PowerPC architecture is based on the IBM POWER architecture,
used in IBM's RS/6000 workstations. Currently IBM and Motorola are
working on PowerPC chips.
The PowerPC architecture specifies both 32-bit and 64-bit data paths.
Early implementations will be 32-bit; future higher-performance
implementations will be 64-bit. A PowerPC has 32 general purpose
(integer) registers (32- or 64-bit) and 32 floating point (IEEE standard
64-bit) registers.
NB: A PowerPC is *not* a computer, any more than an 80486 is a computer.
[2-2] How does PowerPC relate to POWER and POWER2?
As mentioned above, PowerPC is a direct descendant of POWER. POWER2 is
also a descendant of POWER, developed by IBM for use in their
workstations and other systems. POWER2 is an eight-chip multi-chip
module, and was released at approximately the same time as the first
PowerPC chip. While it is faster than the early PowerPC processors, it
is not as fast as the 620 is projected to be. It is likely that IBM will
combine the POWER family into the PowerPC family.
[2-3] What processors have been announced? What are their specs? When
will they be available?
PowerPC 601
The very first PowerPC. It was designed as a bridge between the
POWER architecture and the PowerPC architecture. For this reason, it
incorporates the user-level POWER instructions which were eliminated
from the PowerPC specification.
PowerPC 601v
This is a 601, implemented in a 0.5u CMOS 2.5V process. This
effectively means that it runs faster and draws less power.
(Originally called the "601+".)
PowerPC 602
A processor aimed at consumer electronics (set-top boxes, game
consoles, etc.), PDAs, and embedded controller applications.
PowerPC 603
A low-power processor, intended for portable applications, e.g.,
notebook computers. Performance is roughly comparable to the 601
(see below for benchmarks).
PowerPC 603e
A higher-performance 603 with a faster clock and bigger caches.
(Originally called the "603+".)
PowerPC 603ev
A lower-voltage, faster-clock version of the 603e.
PowerPC 604
A higher-performance processor, intended for high-end desktop
systems.
PowerPC 604e
A 604 with larger caches.
PowerPC 620
An even higher-performance processor, aimed at high-end systems and
multiprocessors. The 620 is the first 64-bit PowerPC implementation.
G3 Series
The "next generation" of PowerPC processors, expected to ship in
1997.
G4 Series
Expected in 1999.
The 601 is manufactured by IBM and sold by both IBM and Motorola. The
603 and 603e are manufactured by both IBM and Motorola.

Notes:
* Bus clock multipliers: the internal CPU clock runs at a multiple of
the external bus clock; "1-4 (+0.5)" means the possible multipliers
are 1, 1.5, 2, 2.5, 3, 3.5, and 4.
* Data width: width of the general purpose (integer/address)
registers and integer ALU(s), in bits
* Bus width: external memory data bus width, in bits -- the memory
bus can be, and often is, wider than the internal data path
* Functional units: I = integer unit
FP = floating point unit
BP = branch processing unit
LS = load/store unit
* Cache: On-chip cache in kilobytes - two numbers means
instruction/data; one number means unified
* Price: in US dollars, for large quantities
* Trans: number of transistors, in millions
* Si date: first silicon date

[2-4] What processors have been announced by companies other than IBM
and Motorola?
Exponential Technology, Inc. <URL:http://www.exp.com/> has announced a
new line of PowerPC processors. They will be fabricated in BiCMOS
technology -- the logic is bipolar, and the memory (registers, cache,
etc.) is CMOS. Their first processor, the X704, will run at 466, 500,
and 533 MHz, and is expected to ship in volume in mid-1997.

[2-5] What embedded controllers will be available?
IBM has announced the PowerPC 4xx embedded controller family. These will
be available as general purpose microcontrollers, application-specific
processors, and ASIC cores. The 4xx family will integrate caches and
other system-level logic to facilitate simpler and cheaper designs. The
available chips are the 403GA and 403GB, and the newer 401GF. The 401GF
be available at speeds from 25 to 100 MHz.
Motorola has announced the MPC500 family of microcontrollers. These
microprocessors will be "100% compatible" with the MPC600 series. The
first chip in this family, the MPC505, will run at 25 MHz. Samples of
the 25 MHz chip are expected in 4Q 1994, with 40 MHz parts expected by
4Q 1995. The MPC505 consists of a PowerPC core, a 4 kB SRAM module, and
a multi-functional system integration unit (SIU) (similar to the 68300
family).
Motorola's PowerQUICC (Quad Integrated Communications Controller) family
integrates a PowerPC core with a communications processor. These chips
are aimed at telecommunications and networking applications. The first
PowerQUICC chip, the MPC860, will come in 25 MHz and 40 MHz versions,
and is expected to sample in 4Q1995 with volume shipping in 2Q1996.
The Motorola MPC821 is similar to the MPC860, but is targeted at PDAs
and other portable devices. The MPC821 incorporates a PowerPC core, a
communications processor module (CPM) for signal processing, a PCMCIA
controller, and an LCD controller. It will be available in 25 MHz and 40
MHz versions, with sampling in October 1995 and production quantities in
January 1996.
The list of Embedded PowerPC Internet Resources
<URL:http://www.cera2.com/gatoxppc.htm>, has pointers to lots of useful
information.
[2-6] How fast is a PowerPC?
This tables lists SPEC92 and SPEC95 results for PowerPC machines, as
well as a few others, for comparison purposes. (SPEC is a benchmark
suite designed to test system performance. The SPECint portion uses
integer-only code, e.g., compilers; the SPECfp program uses floating
point code, e.g., circuit simulation.)

Notes:
* SPEC does not allow estimated figures. The lines which are marked
"estimate" are not officially SPEC numbers, and are likely to be
proven inaccurate when real machines are released.
* Cache numbers are in kB or MB: format is external/instruction/data or
external/unified.

systems, is available in the newsgroup comp.benchmarks.
[2-7] Is there special hardware for emulating 68k or x86 processors?
All currently announced emulators are purely software. The PowerPC
architecture has a group of byte-reversing load and store instructions
which might be useful for emulating little-endian x86 processors on a
big-endian PowerPC system (such as an RS/6000 or a Power Macintosh).
There are no PowerPC processors with additional special hardware for
translating instructions from other processor families (but see the next
question). In addition, because software emulation has been reasonably
successful, it seems very unlikely that there will ever be hardware of
this type.
There are several x86 boards available for the PowerMacs. These are
effectively PC clones on a card, and allow you to run PC software
(though not directly on the PowerPC processor, of course).
[2-8] What is the PowerPC 615?
There were a couple of conflicting rumors regarding the 615. The primary
one suggested that the 615 was a PowerPC processor, being designed by
IBM, which would have special x86 emulation hardware. Another rumor
suggested that it would be pin-compatible with Intel OverDrive sockets.
IBM has denied that the project even exists. This is substantiated by
the lack of any mention of the 615 recently.
[2-9] Does PowerPC have anything like Intel's MMX instructions or the
SPARC VIS instructions?
Motorola and IBM have not announced any multimedia instruction set
extensions for the PowerPC.
========================================================================

[3-1] What PowerPC-based workstations are/will be available? When will
they be available? How much will they cost?
IBM offers a line of RS/6000 workstations and servers, based on PowerPC
processors. These all run AIX (IBM's UNIX), and are binary compatible
with all other RS/6000s, including POWER-based systems. SPEC benchmark
figures for some of these are listed in the table above.
The RS/6000 40P is PReP-compliant, which means that it can run Windows
NT, as well as AIX.

in Germany (March 1994). Planned models will feature 50-80 MHz 601's and
75 MHz 603's. The expected release date for the first models was 3Q
1994, but this seems to have slipped.
Canon has announced that it will work with IBM on the PReP
specification. In particular, they plan to work on extensions to PReP
for PDA's and office products.
Tatung sells several PReP-compliant systems. 601-based systems were
available in October 1994. 604-based systems are expected in 1Q95.
DTK Computers (a Taiwanese company) sells an 80 MHz 601 system, which
runs Windows NT, and will run OS/2 when available.
[3-3] What PowerPC-based Apple (and compatible) personal computers
are/will be available? When will they be available? How much will they
cost?
The first Apple Power Macintosh models were released on March 14, 1994.
All PowerMacs run System 7, just like the 68k Macs. They come with an
emulator which will allow them to run 68k Mac applications. Critical
parts of the Toolbox ROM code have been ported and run natively; the
remainder is emulated.
Workgroup servers, the 6150, 8150, and 9150, are also available. These
currently run AppleShare 4.2 (which is partially native for the
PowerMacs). Novell's Processor Independent NetWare (PIN) 4, when
available, may or may not run on these systems (according to rumors, PIN
will only be available on CHRP systems).
The first PowerPC-based PowerBooks were announced in August 1995.

[3-7] What is PReP and how can I get a copy?
The PowerPC Reference Platform (PReP) is a system standard, designed by
IBM, intended to ensure compatibility among PowerPC-based systems built
by different companies. The PReP standard specifies the PCI bus, but
will also support ISA, MicroChannel, and PCMCIA.
According to IBM, PReP-compliant systems will be able to run OS/2, AIX,
Solaris, Taligent, and Windows NT. IBM systems will (of course) be
PReP-compliant. Apple's first PowerPC Macs are not compliant; future
Macs will probably be CHRP-compliant (see below).
The current version of the PReP spec is 1.1.
Here are the instructions for obtaining a copy of the PReP specification
(freely available to all requesters).

[3-8] What is the Common Hardware Reference Platform (CHRP)?
The CHRP is an open platform agreed on by Apple, IBM, and Motorola. All
CHRP systems will be able to run MacOS, OS/2-PPC, Windows NT, AIX,
Solaris, Novell Netware, and possibly other operating systems. CHRP is a
superset of PReP and the PowerMac platforms; thus you'll be able to run
applications written for the PReP operating systems (OS/2-PPC, Windows
NT, AIX) and the PowerMac (MacOS) on the new CHRP systems (under the
same OS they're written for, of course). In addition, any CHRP software
which doesn't require the Mac ROM, serial ports, or ADB ports should run
on PReP machines.
There is some confusion as to whether or not the CHRP standard will
require a ROM socket (for MacOS ROMs). Apple has said that a future
release of MacOS will not require the ROMs.
The CHRP standard was finalized in November, 1995. The specifications
are being published by Morgan Kaufmann Publishers as _PowerPC
Microprocessor Common Hardware Reference Platform: A System
Architecture_, ISBN 1-55860-394-8. It is also available on the WWW
<URL:http://www.austin.ibm.com/tech/chrp/index.html>.
Apple is referring to CHRP as the PowerPC Platform (PPCP). Apple has
more information, including the above book in PDF format, on the WWW
<URL:http://chrp.apple.com/>.
In February 1996, the MacOS was demonstrated on an IBM prototype CHRP
system.
Motorola announced the Yellowknife PowerPC Reference Platform
<URL:http://www.mot.com/SPS/PowerPC/solutions/yellowknife.html> in
November 1996. IBM also announced a reference design called Long Trail
<URL:http://www.chips.ibm.com/products/ppc/Developers/longtrl/longtrail.html>.
These systems can run both MacOS and Windows NT. Full design
documentation for both systems is available to developers.
[3-9] Can PowerPC 601-based computers be upgraded to, e.g., a 604 when
they become available?
This depends on exactly which computer you have. Some of Apple's
PowerMacs have their processors on replacable daughterboards. See also
Question 3-3.
IBM Power Personal Systems will have a 200-pin slot on the motherboard,
apparently intended for a level-2 cache or processor upgrade.
Motorola PowerStack systems provide a L2 cache socket which can also be
used for PowerPC processor upgrades simply by plugging in a
daughterboard.
[3-10] Where can I get the specifications for the PCI bus?
The following documents:
* PCI Spec Rev 2.0
* PCI BIOS Spec Rev 2.0
* PCI Sys Design Guide 1.0
* PCI Local Bus Product Guide
are available for $25 each or $50 for the first three from:
PCI Special Interest Group

Hillsboro, Oregon 97124-6497
Phone: 800-433-5177
FAX: 503-693-0920
[3-11] Can I used any PCI card in my PowerMac/PReP/etc.?
In general, a driver for the particular computer is required to use a
PCI card, i.e., to use a PCI video card in a PowerMac, that card would
have to come with a PowerMac driver.
A list of PCI cards which have PowerMac support is available on the WWW
<URL:http://www.njin.net/~msproul/macintosh/PCIcards.html>.
[3-12] What is FireWire?
FireWire is a joint Apple and TI implementation of the IEEE P1394
SerialBus standard. It is a high-speed (100 Mb/s) serial bus for
peripheral devices; it is intended to replace Apple Desktop Bus (ADB)
and SCSI, for example. FireWire supports automatic configuration
("plug-and-play") and hot-plugging. It is also isochronous, meaning that
a fixed slice of bandwidth can be dedicated to a particular peripheral,
e.g., for video. The draft standard can be obtained from IEEE Customer
Service: 800-678-IEEE, 908-981-0060, fax: 908-981-9667.

[4-1] What operating systems will run on PowerPC-based computers? When
will they be available?
UNIX
Several flavors of UNIX have been (or will be) ported to the
PowerPC.
IBM's AIX has been available since October 1993. AIX 4.1, available
in August, 1994 is PowerOpen-compliant. There will also be a version
called Personal AIX, which will come without certain utilities and
development tools, for IBM's PC's.
Apple will not ship A/UX for the PowerPC.
Tenon Intersystems <URL:http://www.tenon.com/>' MachTen is a
Mach-based UNIX for the Macintosh. Version 4.0, which shipped in
August 1995, runs natively on PowerMacs.
A PowerPC port of Linux is in progress. The currently targeted
platforms are Motorola's 603 & 604-based PowerStack series, IBM's
604-based 8xx series, Be, Inc.'s BeBox, FirePower Systems ES
Hardware, and Apple's NuBus and PCI PowerMacs and clones. For more
information, see the Linux for PowerPC home page
<URL:http://www.linuxppc.org/>. There is another group
<URL:http://www.cs.nmt.edu/~linuxppc/> also working on this project.
The Linux-PMac project is porting Linux PPC to the PCI-based
PowerMacs (Apple models 7200, 7500, 7600, 8500, and 9500, and also
clones with a 601 or 604 processor). See their FAQ
<URL:ftp://cap.anu.edu.au/pub/linux-pmac/FAQ.html>.
The OSF Grenoble Research Institute <URL:http://www.gr.osf.org/> and
Apple <URL:http://www.mklinux.apple.com/> have announced that they
have ported OSF MK (a microkernel based on Mach 3.0) to the
PowerMac. A Linux server runs on top of this microkernel. The
package, called MkLinux (Microkernel Linux), is available for free.
The second developer release (DR2) is now available (as of December,
1996) on CD-ROM and by ftp -- details are on the Apple web site.
This version supports PCI-based as well as NuBus-based systems.
BSDI <URL:http://www.bsdi.com> has a port of their operating system
(BSD/OS) available for the PowerPC. Contact Randy Brem
([email protected]) for information on this port and its availability.
SunSoft has ported Solaris to the PowerPC, and a beta version was
demonstrated in August 1994. However, it looks like there are no
plans to release it commercially, as of January 1997.
Harris Computer Systems Corporation currently offers PowerSX (was
Secure/PowerUNIX), a multi-level secure PowerOpen-compliant
operating system for IBM RS/6000 workstations and Harris Night Hawk
multiprocessors. PowerSX is the first standards-based B2-level
environment available for the RS/6000. PowerUX (was PowerUnix) is
also available. PowerUX and PowerSX are available through Harris
Computer Systems Corp. and IBM Federal. Contact: Lisa Thornhill at
305-977-5615.
MacOS
Power Macintoshes ship with System 7, just like 68k Macs. Critical
parts of the Toolbox (system code in ROM) have been ported to the
PowerPC; the remainder is emulated. Apple analyzed existing code to
determine the most frequently used Toolbox routines, and ported
those first.
Apple has ported the MacOS to other platforms. See the description
of MAS and MAE in Question 4-6.
With the CHRP announcement (see Question 3-8), Apple announced that
it would start selling the MacOS independently of Apple hardware.
This means that a user will be able to buy MacOS in a store, and
install it on any CHRP system. Whether MacOS for CHRP systems will
be entirely on disk or on ROMs is still up in the air.
Apple has announced a new OS, codenamed Rhapsody, based on the
OPENSTEP API. See Question 4-4.
Windows NT
Windows NT has been ported to the PowerPC. Version 3.5 has been
shipping to developers since October 1994. Systems shipped with NT
have been available since early 1995. The current version is 4.0,
released in August 1996.
IBM and Motorola announced in December 1996 that they will no longer
sell systems with Windows NT. The current release of NT will be
supported, but Microsoft will not release any future versions for
the PowerPC.
OS/2 (was WorkplaceOS)
OS/2-PPC will be source code compatible with OS/2-x86 for 32-bit
applications, i.e., 32-bit OS/2 applications will run natively after
recompiling. 16-bit OS/2 applications will have to be ported to
32-bit before reompilation. OS/2-PPC will provide an emulator for
MS-DOS and Windows code (see below), however it will not support
OS/2-x86 code. The first alpha release of OS/2-PPC was sent to
developers in Nov., 1994. A final version was released in January
1996, but is only available for IBM's desktop systems (the 830 and
850), and must be special ordered from IBM. (See also Question 4-5.)
Others
Taligent (see Question 4-3 below).
LynxOS is a real-time UNIX-like operating system, which has been
ported to the 601, 603, and 604. It is currently available for

[4-2] What is PowerOpen?
The PowerOpen Association defines and promotes the PowerOpen Environment
(POE). The POE is a PowerPC-based standard for operating systems and
applications. Most work so far has been with UNIX-like systems. The POE
is not an operating system; it is a definition containing an application
program interface (API) specification as well as an application binary
interface (ABI) specification. The presence of the ABI specification in
the POE is a factor distinguishing PowerOpen from other open systems
(POSIX, XPG4, etc.) since it allows achievement of platform independent
binary compatibility. Any POE-compliant operating system will be able to
run all POE software. Other non-POE standards cannot provide binary
compatibility over several hardware platforms, and usually limit a
software version to a specific platform.
The POE is an open standard, derived from AIX and conforming to industry
open standards including POSIX, XPG4, Motif, etc. The POE specification
is publicly available to anyone, and is especially of interest to those
producing either applications or hardware platforms. The PowerOpen
Association provides the necessary conformance testing and POE branding.
The key features of the POE are:
* Based on the PowerPC architecture
* Hardware bus independence
* System implementations can range from laptops to supercomputers
* Requires a multi-user, multi-tasking operating system
* Networking support
* X windows extension
* Macintosh Application Services extension
* Motif
* Conformance tested and certified by an independent party (PowerOpen
Association)
The PowerOpen Association has a WWW page
<URL:http://www.poweropen.org/>. More information, including key white
papers, resides there. Topics include:
* PowerOpen Association Fact Sheet: about the organization and
membership
* PowerOpen Certification of Compliance: about POE compliance
* PowerOpen Association Q & A
(The above text was provided by the PowerOpen Association.)
NB: PowerOpen is not itself an operating system -- it is only a
*standard* for operating systems.
The PowerOpen Association consists of IBM, Motorola, Apple, Bull,
Thomson-CSF, Harris, Tadpole Technology, and others.
The PowerOpen specification applies to UNIX-like operating systems. AIX
4.1, available in August, 1994 is PowerOpen-compliant. Apple's System 7
will not be PowerOpen-compliant.
For more information contact Gordon Kass ([email protected]) or Chris
Adams ([email protected]).
[4-3] What is Taligent / Pink?
Taligent <URL:http://www.taligent.com/> was founded jointly by Apple and
IBM in March 1992. It is now a subsidiary of IBM. They are working on
object-oriented "framework technologies and products".
Taligent was originally supposed to release their own OS. Pink is an
older name for Taligent, dating back to work that Apple did before the
formation of Taligent.
[4-4] Will NeXTStep be ported to the PowerPC?
In December 1996, Apple <URL:http://www.apple.com/> acquired NeXT
Software, Inc. <URL:http://www.next.com/> Steve Jobs will be responsible
for a new OS for the Mac, codenamed Rhapsody, which will incorporate an
OPENSTEP-based API, as well as a MacOS compatibility module. Apple plans
to supply two operating systems -- MacOS and Rhapsody -- for the next
few years. The first developers release of Rhapsody is planned for late
1997; the general customer release is expected in 1998.
[4-5] What is WorkplaceOS? Will OS/2 be available on PowerPC-based
computers?
Workplace is a microkernel-based architecture (based on Mach 3)
developed by IBM. According to the initial hype, Workplace was supposed
to be used as the foundation for several different operating systems.
OS/2 for PowerPC is currently available (see Question 4-1). Note that
some confusion has been caused by the fact that the development name for
OS/2-PPC was WorkplaceOS (WPOS) -- this name is no longer used.
[4-6] Can IBM-PC / Macintosh software be run on PowerPC-based computers?
Several emulators have been announced. Generally, these are intended to
run Macintosh or MS-DOS/Windows applications under the various native
operating systems.
Macintosh
Macintosh Application Services (MAS), supported by Apple, allows
PowerOpen-compliant OS's to run Mac applications. MAS includes a
68040 emulator and a PowerPC port of the Mac toolbox, so it will run
both 68k and PowerPC Mac binaries. It is unknown when (or if) MAS
will be available.
Apple, in cooperation with Sun and HP, has released the Macintosh
Application Environment (MAE). MAE allows Mac applications to run
under X Windows on Sun SPARCstations and HP 9000 series 700
workstations. MAE emulates a 68LC040, but critical parts of the
Toolbox run natively. MAE is similar to MAS, but only runs 68k
binaries. For more information, see the MAE WWW site
<URL:http://www.mae.apple.com/>. A demo version is available by ftp
<URL:ftp://ftp.support.apple.com/pub/mae/product-trial/>.
Executor, produced by ARDI <URL:http://www.ardi.com/>, is currently
available for MS-DOS (including Windows and OS/2), Linux, and
NEXTSTEP (Intel and 68k). Executor emulates a 68LC040 Macintosh
running System 6.0.7, with most System 7 features available.
Executor 2 should be ready for release in May 1996. ARDI uses
reverse-engineered Toolbox code, i.e., it was written from scratch
from the interface specs without using any code from Apple. A demo
version is available from ARDI's WWW site.
Power Macintoshes have the built-in capability to run 68k Mac
software. The 68k application code will be emulated, but critical
parts of the system code have been ported. The emulator emulates a
68LC040 (i.e., a 68040 without the FPU).
Speed Doubler from Connectix <URL:http://www.connectix.com/>
includes a faster 68k emulator, among other things.
Be, Inc. <URL:http://www.be.com/> and fredlabs, inc.
<URL:http://www.fredlabs.com/> demoed VirtualMac, a Macintosh
emulator for BeOS in January 1997. No release date has been
announced yet.
MS-DOS/Windows
Wabi, produced by Sun, runs under UNIX/X. It emulates x86 code, and
translates Windows calls to X calls. IBM is working on an 80386
translator. Support has been announced for Solaris and AIX. Wabi is
based on the public specs for the Windows ABI. (Wabi originally
stood for "Windows Application Binary Interface" -- it's written
"Wabi", not "WABI", for trademark reasons.) This has been
demonstrated on IBM's PowerPC personal systems.
SoftPC and SoftWindows, produced by Insignia Solutions
<URL:http://www.insignia.com/>, run under several OS's: Mac OS,
Windows NT, NeXTStep, and various other UNIX flavors. Version 2.0,
released in August, 1995, emulates a 486DX and Windows calls.
Insignia has licensed the Windows source code from Microsoft.
OS/2 for the PowerPC (which was also known as WorkplaceOS) will run
MS-DOS and Windows code via the Instruction Set Translator (IST), an
instruction-caching x86 emulator. OS/2-PPC will not directly run
OS/2-x86 code.
[4-7] What PowerPC development tools are available?
# This is a new question -- I'll be happy to take suggestions for things
# to list here.
PSIM <URL:ftp://ftp.ci.com.au/pub/psim/README> is a free
instruction-level simulator for the PowerPC.
The GNU toolchain (GCC, GAS, GLD, GDB) supports the PowerPC. It's
available from the main GNU ftp site <URL:ftp://prep.ai.mit.edu/> and
its mirrors. There is also a supported version from Cygnus Support
<URL:http://www.cygnus.com/>.
========================================================================
[5] Comparisons
========================================================================
[5-1] Should I buy a PowerPC system rather than a Pentium or 68k system?
Apple is committed to making their Power Macintoshes feel just like the
68k Macs, but faster. It looks like they will eventually switch the
entire Mac line over to the PowerPC. If you plan to buy a new Mac, this
is probably the way to go.
Current Pentium systems run existing x86 code faster than current
PowerPC systems can emulate it. This is not likely to change in the
immediate future. If you need to run x86 code as fast as possible, buy a
Pentium box.
On the other hand, many x86 applications will probably be ported to the
PowerPC. The extent of this porting will likely determine the success of
the PowerPC in the personal computer market.
In terms of pure performance (whatever that is), it looks like there
will be a fairly close race between the PowerPC family and the Intel x86
family (among others). The Intel-HP agreement promises to make things
even more interesting. Only the future will tell whose chips and whose
systems will be the fastest.
[5-2] What will be the differences between the various PowerPC-based
personal computers?
There are currently two major classes of PowerPC-based personal
computers (not counting workstations): the Apple Macintosh line and the
PReP-compliant machines. It now appears that these two groups are
converging on the CHRP standard. In theory, any CHRP-compliant system
will be able to run any CHRP operating system (MacOS, OS/2, Windows NT,
etc.). Whether this will actually materialize remains to be seen.

[6] Miscellaneous
========================================================================
[6-1] What's the deal with Ford and the PowerPC?
Ford and Motorola have signed an agreement resulting in a custom PowerPC
to be used by Ford as a powertrain controller. Details on this chip are
not available.
[6-2] What's the deal with 3DO and the PowerPC?
3DO <URL:http://www.3do.com/> has developed M2, a 64-bit video game
technology which uses the PowerPC 602. The M2 technology has been
licensed Matsushita for use in game consoles. However, 3DO is moving
away from game console hardware to focus on software.
