Intel is expected to launch two new Xeon E5 subfamilies of processors in early 2012 with the E5-1600 and the E5-2600, the latter of which already has its specs and pricing leaked. CPU-World published a list showing the details on every E5-2600 model, revealing what specs we might expect to find with upcoming systems, such as Apple's early 2012 Mac Pros.
Starting form the bottom of the series is a quad-core 1.8Ghz Xeon with 10MB of level 3 cache and no Hyperthreading at a $202 bulk price point. At the high-end, it offers 1.8GHz to 3.1GHz eight-core processors with Hyperthreading, and 20MB of cache, 70W to 150W power use for a price ranging from $1,106 to $2,057. This series has only one dual-core chip with the E5-2643 that's clocked at 3.3GHz and sports 5MB of level 3 cache, Hyperthreading, and 80W power usage, but is priced at $884.
This new lineup could boost the number of cores on systems across the board, especially on Apple's next-gen Mac Pros, which are expected to get refreshed in early 2012. The lower end dual-core model would certainly benefit from the new series, such as with the E5-2620, which would boost it up to 6 cores while maintaining about the same pricing. The lower-end single-core Mac Pro models may use Intel's E5-1600 series processors that's also scheduled to launch in the first quarter of 2012.
