Linux Kernel Compile
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.
The new Xeon E7 server is no less than 3 times faster than the Xeon servers it is likely to replace in the datacenter (the ones based upon the Xeon X7560). Meanwhile the performance advantage over the previous generation is 22%, which is noticeable, but hardly spectacular. The Quad Xeon E7 is however almost twice as fast than the dual Xeon E5. In other words, RAS features are not the only differentiator with the E5 line, raw speed is that too.

I'm shocked to hear that Oracle and IBM are charging more for their SPARC and PowerPC chips, respectively, than Intel is charging for comparable x86 chips - or, at least, I presume they are, if servers using those chips are more expensive. Since x86 has the enormous advantage of being able to run Microsoft Windows, the only way other ISAs can be viable is if they offer better performance or a lower price.Kevin G - Thursday, May 14, 2015 - link
Actually IBM comes in cheaper than Intel for comparable POWER8 hardware. IBM now is offering the processor to outside system builders so the actual prices are some what known. Tyan used to have the raw prices on their site but I can't find them again.Regardless, this article indicates that they top out at $3000 which is less than equivalent Xeon E7's.

Sure, SPARC and POWER are (was in case of POWER) more expensive, but usually hardware price is nothing in comparison with software price if you are running enterprise. Also SPARC is also Oracle preferred over POWER/Itanium by Oracle's price ratios... Anyway, POWER8 looks so powerful that it may even be cheaper software wise in comparison with SPARC, but that would need some clever Oracle DB benchmarking...HighTech4US - Friday, May 15, 2015 - link
Power 9 will be available when?Phiro69 - Friday, May 15, 2015 - link
I wanted to compare the E7's in this review to the E5's reviewed a few months back in your benchmark comparison tool, but I'm not seeing any of this data in it? Is it going to be there?
