Peak 632A User's Guide
3-2 Cache Memory
Since the second level cache has been embedded into the Pentium II CPU. You do
not have to take care of either SRAM chips or SRAM modules. The built-in second
level cache in the Pentium II yields much higher performance than the external ones.
The cache size in the Pentium II CPU is either 256KB or 512KB. Normally, for
workstation and server applications, the 256KB version is good enough. However,
if your system is for heavy duty applications, the 512kB version will help a lot.
Specifically for our Pentium II based SBC, the Pentium II has another version
provide much better data security if combined with the DRAM ECC, please check
with your vendor for various Pentium II models.

The level 2 cache of the Peak 6320A is built in the Celeron/Pentium III current
Celerons have 128 KB on die L2 Cache which is very fast because it’s running at the
CPU speed. Future Celerons/Pentium III might be upgraded to 256 KB L2 Cache.
