Leaked specs expose next-gen Xeon lineup

The Turks over at Donanim Haber have gotten their hands on new details concerning Intel's upcoming Sandy Bridge E processors. The site has posted purported specifications for what looks like the entire lineup of next-generation Xeons, and it's a doozy. Here's the full list:

Model Cores Threads Clock Speed Memory speed L3 cache TDP
Xeon E5-2603 4 4 1.8GHz DDR3-1066 10MB 80W
Xeon E5-2609 4 4 2.4GHz DDR3-1066 10MB 80W
Xeon E5-2620 6 12 2.0GHz DDR3-1333 15MB 95W
Xeon E5-2630 6 12 2.3GHz DDR3-1333 15MB 95W
Xeon E5-2630L 6 12 2.0GHz DDR3-1333 15MB 65W
Xeon E5-2637 2 4 3.0GHz DDR3-1600 5MB 80W
Xeon E5-2640 6 12 2.5GHz DDR3-1333 15MB 95W
Xeon E5-2643 6 12 3.3GHz DDR3-1600 15MB 130W
Xeon E5-2650 8 16 2.0GHz DDR3-1600 20MB 95W
Xeon E5-2650L 8 16 1.8GHz DDR3-1600 20MB 70W
Xeon E5-2660 8 16 2.2GHz DDR3-1600 20MB 95W
Xeon E5-2667 6 12 2.9GHz DDR3-1600 15MB 130W
Xeon E5-2670 8 16 2.6GHz DDR3-1600 20MB 115W
Xeon E5-2680 8 16 2.7GHz DDR3-1600 20MB 130W
Xeon E5-2687W 8 16 3.1GHz DDR3-1600 20MB 150W
Xeon E5-2690 8 16 2.9GHz DDR3-1600 20MB 135W

These details aren't confirmed, but they do look plausible. Highlights? Check out the Xeon E5-2687W, which runs at 3.1GHz and boasts a hefty 150W thermal envelope. Intel's 5000-series Xeon line (which the E5s look set to replace) doesn't have anything with a TDP greater than 130W. That said, the 5000-series family tops out at six cores, three memory channels, and 12MB of L3 cache, while the E5s scale up to eight cores, four channels, and 20MB of cache.

At the very least, Sandy Bridge E appears to have a greater thirst for wattage than its Gulftown predecessor. Take the E5-2667, for example. It has the same core count and clock speed as the existing Xeon X5670. However, the X5670 has a 95W thermal envelope, while the E5-2667 has a 130W TDP. Thankfully, the E5 lineup has a number of low-power options, including an eight-core model with a 70W TDP rating.

Donanim Haber doesn't have any new information on pricing or an expected street date for these new CPUs. I suspect we'll see at least a couple of the new Xeon variants manifest themselves as Extreme Edition desktop chips targeted at X79 mobos, but we don't yet have a clear indication of when those chips will arrive.
