Specifications of Intel Xeon E5-2600 v2 CPUs

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:

Since when were you into computer stuff like CPUs, Azu-nyan?

Xeon E5-2667 v2 has 25 mb cache, it cannot be 8 core processor. You can check it on Asrock CPU Support List.

I doubt that the info on the Asrock website is actually entirely correct - just take a look at the following table of current-gen procs.

Frequency Optimized Xeon E5-2600 Processors:

Xeon E5-2637 2c 3.00GHz 5MB 80Watt
Xeon E5-2643 4c 3.30GHz 10MB 130Watt
Xeon E5-2667 6c 2.90GHz 15MB 130Watt
Xeon E5-2687W 8c 3.10GHz 20MB 150Watt

If you look at the next-gen specs you'll find that the 22nm process seems to allow them to add 2 cores and 0.1-0.4GHz on pretty much all models while maintaining a similar or even the exact same TDP.

So as Nakano rightly pointed out, the E5-2643 gets bumped to 6 cores and the given 3.5GHz for v2. Just compare that to the leaked specs for the i7-4960X which are almost identical, so it does make sense.

Similarly, the E5-2667 gets beefed up from 6 to 8 cores at 3.3GHz. Just compare the reputed v2 specs for the 2643, 2667 and 2687W - these certainly don't make sense at all:

Xeon E5-2643 v2 10c 3.5GHz 25MB 130Watt
Xeon E5-2667 v2 10c 3.3GHz 25MB 130Watt
Xeon E5-2687W v2 10c 3.4GHz 25MB 150Watt

By the way - I wouldn't be surprised if the i7-4970X, when it comes out, will get 8 cores at say 3.6GHz or so but that's obviously pure (hopeful) speculation... ;)

about some details

I agree that certain details may be inaccurate. However, there are certain circumstances and can not support the specification that is Asrock`s list. It is possible that certain models of processors that are confusing with their high frequency does not have Hyper-threading. Intel is once more in the Westmere-ex generation had to offer that solution. After all, do not forget that they even then had to offer processors with 10 cores, with the active option Hyper-Threading and a frequency of 2.4 GHz and all that with a TDP of 130W. As for the model Xeon e5 2687w v2 does not believe that the only improvement over the previous generation (sandy bridge) was the elevation of the frequency of 300 MHz. I think it makes more sense to carry v2 and 2 more cores.

The 2687W v2 is indeed likely to get 10 cores but that wasn't my point. It was specifically about the 2667 v2 (and the 2643 v2). :]

however, Glenn Berry has also published a list with a note to the processor on which there was to say.

Yes, I agree, only the specifications for the 2643 v2 is most problematic. I apologize for the accidental publication of the same two answers.
