Intel 8-Core Sandy Bridge-EP Processors Have 150W TDP

This information was spotted in a leaked screenshot of CPU-Z that was running on a dual socket system with two Sandy Bridge-E LGA 2011 processors. The processors had a base clock speed of 3.0GHz, 20MB of Level 3 cache memory, and each one of them could process up to 16 threads simultaneously, thanks to Intel's HyperThreading technology.

The same source that provided this screenshot also has a CPU-Z picture of another Sandy Bridge-EP 8-core processor that comes clocked at 2.3GHz and has a TDP of 130W.

The Xeon E5 processor line will comprise three CPU series, dubbed E5-1600, E5-2600 and E5-4600, and all of these carry a similar feature set, but the latter are compatible with dual-socket and quad-socket motherboards.

Outside of the eight processing cores and 20MB of L3 cache, Sandy Bridge-EP chips also include up to 2 QPI links, 40 PCIe Gen3 lanes, 4 DMI 2.0 lanes, and an integrated quad-channel DDR3 memory controller that support up to three DIMMs per channel for a maximum of 96GB.

Intel's Xeon E5 processor family is expected to arrive in the fourth quarter of this year, while the first desktop Sandy Bridge-E models will be released in Q1 2012.
