While the Intel X99 series motherboards are popular right now with the Intel Core i7 Haswell Extreme Edition CPUs, some of these motherboards are also compatible with the Haswell-based Xeon processors. The MSI X99S SLI PLUS does officially support a number of the Haswell-EP Xeon processors, including the E5-2687W v3 that's a ten core processor plus Hyper Threading. In making for some interesting Linux results, MSI kindly sent over the Xeon E5-1680 v3 and E5-2687W v3 to test them with their X99S SLI PLUS motherboard under a variety of conditions with Linux.
In recent days on Phoronix there's been a number of Intel Xeon Linux tests using these new processors, among them:
- Intel Xeons Running Great On MSI's X99 Motherboard With Linux
- LLVM Clang vs. GCC On Fedora 21 With A High-End Xeon
- GCC 5 Is Compiling Faster, But Still Falls Short Of Clang
- Ubuntu 14.10 vs. Scientific Linux 7.0 Trial Benchmarks With A Haswell-EP
- GCC Compiler Optimization Benchmarks With A 16-Thread Haswell-EP
- Intel Xeon P-State vs. CPUFreq Scaling Tests Show Some Odd Numbers
Those were the tests done in less than two weeks while many more Haswell Xeon Linux benchmarks are coming on Phoronix thanks to MSI sending over these test samples. The tests we're looking at today is comparing the Xeon E5-1680 v3 and Xeon E5-2687W v3 on the same platform to the Intel Core i7 5960X Haswell Extreme Edition processor.
The Intel Xeon E5-1680 v3 has eight cores plus Hyper Threading, 3.2GHz base frequency, 3.8GHz turbo frequency, 20MB Smart Cache, 140 Watt TDP, and has a tray price of $1723 USD.
The Intel E5-2687W v3 is a ten core processor plus Hyper Threading, clocked at 3.1GHz, boasts a 3.5GHz turbo frequency, 25MB Smart Cache, 160 Watt TDP, and has a tray price of $2141 USD.
For reference, the Core i7 5960X $999 processor has eight cores plus Hyper Threading, 3GHz base frequency, 3.5GHz Turbo frequency, and 20MB Smart Cache. Other differences between the i7-5960X and Xeon Haswell processors include the workstation/server CPUs supporting ECC memory, vPro, Demand Based Switching, Intel Secure Key, OS Guard, and Trusted Execution Technology.
