Intel Xeon E5 Version 3: Up to 18 Haswell EP Cores

SKUs and Pricing

Before we start with the benchmarks, let's first see what you get for your money. To reduce the clutter, we have not listed all of the SKUs but have tried to include useful points of comparison. Also note that we are not comparing pricing or performance with AMD at this point, as AMD has not updated its server CPU offerings for almost 2 years. The Steamroller architecture was very promising and addressed many of the bottlenecks we discovered in the earlier Opteron 6200, but unfortunately it was never made into a high end server CPU. So basically, Intel's only competition right now is the previous generation Xeons, which means Intel has to convince server buyers that upgrading to the latest Xeon pays off.

At the top of the product stack is the new E5-2699 v3, and it's priced accordingly: over $4000 for the most cores Intel has ever put in a Xeon processor. TDP has also gone up compared to the previous generation's top SKU, but for six additional cores that's probably reasonable.

At first glance, the 2695 v3 looks interesting for the performance hungry as it the cheapest "HCC" (High Core Count) option. You get the largest die with the two memory controllers, 35MB LLC, two rings, and TDP is limited to 120W. Of course the question is how well Turbo Boost will compensate for the relatively low base clock.

For those looking for a good balance between price/performance and power, the 2650L v3 offers a 100MHz higher clock, much higher Turbo Boost, two extra cores, and a slightly lower TDP for about $100 more. This SKU looks very tempting for people who do not need the ultimate in processing power, e.g. those looking for a host for their VMs.

Lastly, there is the 2667 v3 which has a high base clock (3.2) and a still reasonable TDP of 135W for all applications that need processing power but do not scale beyond a certain core count.

Those are the SKUs that we have included in this review, so let's see how they fare.
