512 KB or 1 MB of back-side second-level (L2) cache on processor module (depending on model and configuration). The cache runs at one half the clock frequency of the microprocessor. For example, the cache would run at 166.5 MHz on a 333 MHz processor module. | 512 KB or 1 MB of back-side second-level (L2) cache on processor module (depending on model and configuration).
