Intel Xeon E5 model speeds explained
Intel's Xeon E5 processors may have been spoiled in earnest with a detailed listing of every E5-2600 model at CPU-World. Intended for dual-socket computers, they will start off with a quad-core, 1.8GHz Xeon with 10MB of Level 3 cache and no Hyperthreading, but with a $202 price point in bulk. The line will culminate in eight-core models at between 1.8GHz to 3.1GHz, Hyperthreading, power use between 70W and 150W, 20MB of cache, and prices between $1,106 and $2,057.
Unlike the Xeon 5000 chips from 2010, just one dual-core chip, the 3.3GHz E5-2643, will be available with 5MB of cache, Hyperthreading, an 80W draw, and an $884 price. Five six-core editions between 2GHz and 2.9GHz will sit in the middle of the line.
The initial versions should be available in early 2012 along with Intel's mainstream Ivy Bridge (third-generation Core) processors.
Intel's lineup, if shipped as detailed, should lead to workstations and servers with many more cores on average. While expected, it could give one of the bigger improvements for Apple, which had inadvertently slipped plans for a 16-core Mac Pro. With two eight-core processors and Hyperthreading, it could have the equivalent of 32 active cores and greatly speed up pro 3D rendering, video encoding, and server-level chores. [via MacRumors]
