In this and the next two quarters, Intel is going to release single-, dual- and quad-socket server processors built on Ivy Bridge microarchitecture. The first CPUs to launch are Xeon E-2600 v2 and E5-1600 v2, that will be available in Q3 2013. In the past, we published common features present on many Xeon E5 series CPUs for socket LGA2011, but we did not know exact SKU lineup. Luckily, earlier this month TechPowerup found some details of E5 SKUs in ASRock's CPU support list.
Although the support list contains model numbers, clock speeds, TDP and the size of L3 cache, it does not mention such important parameters as the number of cores, Hyper-Threading support, or maximum Turbo Boost frequency. Some characteristics, like the number of cores, could be guessed from the size of L3 cache. Each core on Ivy Bridge-EP microprocessors is paired with 2.5 MB piece of shared L3 cache, consequentially the number of cores can be calculated as the L3 cache size divided by 2.5. Based on our calculations, Xeon E5-2600 v2 processors will have from 8 to 12 cores, depending on SKUs. The parts will incorporate up to 30 MB of L3 cache, and operate at frequencies as high as 3.5 GHz. Even though the number of cores was increased by 50%, Intel managed to keep TDP in line with the first E5-2600 generation, that is at 95 - 115 Watt for standard power parts, and at 130 - 150 Watt for high performance chips.
Xeon E5-2697 v2 and E5-2695 v2 have the maximum number of cores and the maximum size of L3 cache. These CPUs operate at 2.4 GHz and 2.7 GHz, and they are rated at 115 Watt and 130 Watt.
Xeon E5-2660 v2, E5-2667 v2, E5-2670 v2, E5-2680 v2 and E5-2690 v2 are 10-core microprocessors with 25 MB L3 cache. They run at 2.2 GHz - 3.3 GHz, and have TDP ranging from 95 Watt to 130 Watt. Another 10-core CPU, E5-2687W, is clocked at 3.4 GHz, but it also has higher 150 Watt power rating. The support list also mentions Xeon E5-2643 v2 model with 25 MB L3 cache, that has even higher clock speed, but we are not sure if it has 10 CPU cores or less.
The only low-power SKU in the lineup is Xeon E5-2650L v2. It has 10 CPU cores, 1.7 GHz frequency, and 70 Watt TDP.
Eight-core Xeon E5-2600 v2 microprocessors are E5-2640 v2 and E5-2650 v2. They have 2 GHz and 2.6 GHz frequencies, 20 MB of last level cache, and they fit into 95 Watt thermal envelope.
Older reports indicated that E5-2600 v2 CPUs will integrate 2 QPI links, up to 40 lanes of PCI Express 3.0 interface, and 4-channel DDR3 memory controller, supporting DDR3-1866 memory. Below is a summary of known specifications of Xeon E5-2600 v2 processors:
