I have seen repeatedly that at twelve core counts and higher that some of the tests simply do note scale with more cores. I will start off this section by saying that the standard test suite was built to test UP platforms. Overall, this is a fairly solid dual Xeon platform that can be used to attach 22 hard drives and that has a ton of expandability.
A PicoPSU 150XT is simply an unrealistic power supply for this configuration. With all of the PCIe lanes, the board offers a TON of expandability beyond the dual CPUs. The platform has dual IOH36 controllers and an onboard LSI SAS2008 controller. The PicoPSU 150XT could not power this configuration, which frankly makes a lot of sense. It should be noted that this build cannot be directly compared to the UP power consumption numbers simply because I am using more fans than normal (most test configurations are single-fan with a PicoPSU). To get power consumption numbers I removed all add-in cards. I detailed the dual Xeon processor build in an earlier dual processor test bed build log piece. The test platform was the same as the dual Intel Xeon E5606 review. At a base clock of 2.93GHz and a turbo clock of 3.33GHz using a 6.4GT/s QPI alongside a higher 95w TDP, one can imagine that performance is going to be stellar. The L5640 was fast, but let’s see how adding another 533MHz to twelve physical, twenty-four logical cores fares in terms of performance.
INTEL XEON HEXA 6 CORE SERIES
Although quad socket capable, the X5670 is also dual socket capable and fills a position that the Xeon E series does not scale to at this time. Although the Intel Xeon L5640 is a lot of processor with very low power consumption requirements, the Intel Xeon X5670 is a much higher-end part.
