Compiling with gcc

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 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 readable, the number of seconds in wall time was converted into the number of builds per hour.

Linux Kernel Compile

The Xeon D delivers at least 65% better performance than the Xeon E3s. Considering the low TDP, that is pretty amazing. The Xeon E5 delivers 30% more with 50% more cores - as the Xeon E5 is twice as expensive, the Xeon D holds a massive performance per dollar advantage. The brawny Broadwell cores of the Xeon D compile no less than 3.7 times faster than the small Silvermont cores of the Atom, meaning that compiling definitely favors the more sophisticated cores. 

If you regularly compile large projects, the Xeon D is one of the best choices you have - even compared to a highly clocked Core i7 solutions. The cheaper quad core i7s will perform like the Xeon E3-1240, the equally priced ($583) i7-5930k will do about 50% better, still below the Xeon D. The Xeon D offers you integrated dual 10 Gb Ethernet, SATA, USB, which should offer lower latency. The Xeon D can also support twice as much memory (128 GB vs 64 GB) and offer you a much lower power bill (45W vs 140W TDP), making hardware decisions around compilation based projects an easy choice to make.

    Nice stuff. Realy good to see them bringing power consumption down pr. Performance. Reply

    Nice way to confuse people. Codename Yosemite Reply

    Who would this confuse? Apple fans because of the OS witht he same codename?

    LOL. Believe me they don't know, or care... Most of them aren't even aware of what a "server" chip is, or even what a "server" is used for.

    Rails developer checking in to remind you that a great chunk of the Rails community develop using OS X to deploy on Linux and hence is aware of "server chips". Even though you said that "most" Apple users don't know what a server chip is and that's accurate, the same could be said about Windows or even Linux common users. Stop patronizing.

    All being said, I agree with you. Who could possibly confound the Xeon D's codename coincides with OS X's 10.10 name?

    First of all, your implication that apple fans don't know jack shit about servers is a broad generalization, and a stupid one at that.

    Second of all, anyone who knows enough to even consider buying a Xeon and a motherboard that supports it and the ECC memory, probably knows enough to not get confused. And plenty of mac users know what server chips are and what they're used for.

    Nice trolling though.

    That's not entirely true, but I will agree that people a lot of the people who use Apples( No discrimination intended) only continue to use Apple due to their lack of tech knowledge( like knowing Android is the king :) . And, yes, they probably won;t know what servers even are. Reply

    Geographic code names are the norm in the computing industry (I think because they cannot be copyrighted) and they end up being reused. For example, Intel Seattle is/was a motherboard and AMD Seattle is/was an ARM64 processor. See etc. if you would like to look for more examples :-) Reply

    Any places in the US that the motherboard is available for purchase? Quick checks looks like it's mostly sold out or otherwise unavailable? Reply

    Availability comes and goes. Xeon D has been a big hit in the large scale deployment markets and they've been soaking up a lot of demand for it, both bare and combined on motherboards like the supermicro offerings severely limiting retail availability. But it is available in retail but quantities are limited. Quite a number of people over at servethehome have gotten their hands on them. If you want one, you'll likely have to keep checking the major sites like newegg, amazon, et al for them to come back in stock. Retail boards are generally in the $800-1000 range atm (basically going for full list but then again bare motherboards with 10gbe tend to go for 600+ so its still a good buy and simple new 10gbe cards tend to go for $300-500).

    How come they call this a SoC if there's no integrated module to drive even a simple display, and they apparently need a discrete PCIe graphics card for that D-SUB output? Reply
