All Xeon Models | Hardware Secrets

Xeon 30xx, 51xx and 72xx processors are based on the latest Intel microarchitecture, Core, the same used by Core 2 Duo processors. These CPUs were known in the past as Woodcrest, Intel codename for this CPU generation. If you want to learn more about the new Core microarchitecture, read our tutorial on this subject.

Keep in mind that dual-core Xeon from the series described on the previuos page (50xx, 70xx and 71xx) are based on Pentium 4 microarchitecture (NetBurst) carrying Hyper-Threading technology, which is not available on Core microarchitecture.

All Xeon 30xx, 51xx and 72xx series have the following features:

Core microarchitecture
Dual-core technology
65 nm manufacturing process
Socket 604 (72xx models), 771 (51xx models) or 775 (30xx models)
SSE3 Instruction Set
32 KB L1 instruction cache and 32 KB L1 data cache.
4 MB L2 cache shared by the two cores
Execute Disable technology
EM64T technology
Virtualization technology
Demand-Based Switching (DBS) technology on 5140, 5148, 5150 and 5160 models.
Enhanced SpeedStep technology
Dual Independent Bus (DIB) Technology, where each core has its own external bus instead of the two cores sharing the same external bus.

Below you can find all Xeon 30xx, 51xx and 72xx 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.
