The video RAM (VRAM) in the Macintosh Quadra 950  uses 80 ns devices instead of the 100 ns devices used in the [[Macintosh Quadra 900]]. The video controller (DAFB) has been reprogrammed to take advantage of the faster VRAM, speeding up video performance by as much as 20%. That speed increase is in addition to the increase due to the 33 MHz processor speed. The cumulative increase in video performance can be as much as 50% overall.

The PDS attaches to the pins of the MC68040 without any buffers. For a PDS card to operate properly in the Macintosh Quadra 950 , the card must be capable of meeting the 33 MHz timing specifications of the MC68040.
