All Xeon Models | Hardware Secrets

Xeon 32xx, 53xx and 73xx processors are based on Core microarchitecture and have four processing cores. These four cores are obtained from two dual-core dies. Because of that the L2 memory cache from these processors isn’t shared between all cores: cores 1 and 2 share the same L2 cache, while cores 3 and 4 share another L2 cache. The L2 memory cache size announced is the total amount of L2 cache available (i.e. the sum of the two caches). Read our Intel Quad-Core Overview and Roadmap article for a more detailed explanation on the architecture used by these CPUs.

All Xeon 53xx and 73xx series have the following features:

Core microarchitecture
Quad-core technology
65 nm manufacturing process
Socket 604 (53xx and 73xx models) or 775 (32xx models)
SSE3 Instruction Set
32 KB L1 instruction cache and 32 KB L1 data cache.
4 MB, 6 MB or 8 MB L2 memory cache.
Execute Disable technology
EM64T technology
Virtualization technology
Enhanced SpeedStep technology

Below you can find all Xeon 53xx and 73xx models released to date. TDP stands for Thermal Design Power and indicates the CPU maximum thermal dissipation, i.e. the CPU cooler must be able to dissipate at least this amount of heat.
