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.

MY God - It's full of transistors!Samus - Monday, September 8, 2014 - link
I wish there were socket 1150 Xeon's in this class. If I could replace my quad core with an Octacore...wireframed - Saturday, September 20, 2014 - link
If you can afford an 8-core CPU, I'm sure you can afford a S2011 board - it's like 15% of the price of the CPU, so the cost relative to the rest of the platform is negligible. :)Also, s1150 is dual-channel only. With that many cores, you'll want more bandwidth.

For many, if not most workloads it will be faster to run 4 fast (4GHz) cores on 4 fast memory channels (DDR4-2400+) than 8 slow (2-3GHz) cores on 2 memory channels. Of course, if your workload consists of a lot of trigonometry (sine/cosine etc), or thread worksets completely fit into 2nd level cache (only 256k!), you may benefit from 8/2 config. But if you have one of those, I am eager to hear what it is.tech6 - Monday, September 8, 2014 - link
The 18 core SKU is great news for those trying to increase data center density. It should allow VM hosts with 512Gb+ of memory to operate efficiently even under demanding workloads. Given the new DDR4 memory bandwidth gains I wonder if the 18 core dual socket SKUs will make quad socket servers a niche product?Kevin G - Monday, September 8, 2014 - link
In fairness, quad socket was already a niche market.That and there will be quad socket version of these chips: E5-4600v3's.

My lord. My thought is that this really shows that v3 isn’t the slouch many thought it would be. An added 2 cores over v2 in the same price range and turbo boosting that appears to functioning a little better, plus the clock for clock improvements and move to DDR4 make for a nice step up when all combined.I’m surprised Intel went with an 18 core monster, but holy S&%T, if they can squeeze it in and make it function, why not.

I feel for AMD, this just shows how far ahead Intel is :\Thermogenic - Monday, September 8, 2014 - link
Intel isn't just ahead - they've already won.olderkid - Monday, September 8, 2014 - link
AMD saw Intel behind them and they wondered how Intel fell so far back. But really Intel was just lapping them.
