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

A more real world benchmark to test the integer processing power of our Xeon servers is a Linux kernel compile. Although few people compile their own kernel, compiling other software on servers is a common task and this will give us a good idea of how the CPUs handle a complex build.
To do this we have downloaded the 3.11 kernel from kernel.org. We then compiled the kernel with the "time make -jx" command, where x is the maximum number of threads that the platform is capable of using. To make the graph more readeable, the number of seconds in wall time was converted into the number of builds per hour.
A kernel compile does not scale perfectly with more cores, but the Xeon E5-2699 still holds a healty lead over its 14-core brother. The Haswell architecture's improved integer core plays a larger role here than in compression as the E5-2697 v2 with 50% cores and a maximum clock of 3GHz (all cores Turbo Boost) cannot overtake the 3.2GHz Xeon E5-2667 v3. It is worth noting that the latter cannot Turbo Boost with all cores active.
The advantage over the Sandy Bridge EP is significant: 50% higher performance while the clock speed is only slightly higher as the Xeon E5-2690 can run briefly at 3.3GHz. The new Haswell core is good news for those who regularly deal with large software builds.

In the SKU comparison table you have the E5-2690V2 listed as a 12/24 part when it is in fact a 10/20 part. Just a tiny quibble. Overall a fantastic read.KAlmquist - Monday, September 8, 2014 - link
Also, the 2637 v2 is 4/8, not 6/12.isa - Monday, September 8, 2014 - link
Looking forward to a new supercomputer record using these behemoths.Bruce Allen - Monday, September 8, 2014 - link
Awesome article. I'd love to see Cinebench and other applications tests. We do a lot of rendering (currently with older dual Xeons) and would love to compare these new Xeons versus the new 5960X chips - software license costs per computer are so high that the 5960X setups will need much higher price/performance to be worth it. We actually use Cinema 4D in production so those scores are relevant. We use V-Ray, Mental Ray and Arnold for Maya too but in general those track with the Cinebench scores so they are a decent guide. Thank you!Ian Cutress - Monday, September 8, 2014 - link
I've got some E5 v3 Xeons in for a more workstation oriented review. Look out for that soon :)fastgeek - Monday, September 8, 2014 - link
From my notes a while back... two E5-2690 v3's (all cores + turbo enabled) under 2012 Server yielded 3,129 for multithreaded and 79 for single.While not Haswell, I can tell you that four E5-4657L V2's returned 4,722 / 94 respectively.
Hope that helps somewhat. :-)

I don't see a way to edit my previous comment; but those scores were from Cinebench R15wireframed - Saturday, September 20, 2014 - link
You pay for licenses for render Nodes? Switch to 3DS, and you get 9999 nodes for free (unless they changed the licensing since I last checked). :)Lone Ranger - Monday, September 8, 2014 - link
You make mention that the large core count chips are pretty good about raising their clock rate when only a few cores are active. Under Linux, what is the best way to see actual turbo frequencies? cpuinfo doesn't show live/actual clock rate.JohanAnandtech - Monday, September 8, 2014 - link
The best way to do this is using Intel's PCM. However, this does not work right now (only on Sandy and Ivy, not Haswel) . I deduced it from the fact that performance was almost identical and previous profiling of some of our benchmarks.
