In continuation of last week's article about building an Intel Xeon E3 v5 Skylake Linux system, here are my complete performance figures on the Xeon E3-1245 v5 as a $300 Skylake processor featuring HD Graphics P530.
In that earlier article about the Skylake Xeon system build, I shared benchmarks comparing the performance of this brand new system against dozens of other systems used for benchmarking at Phoronix Media. The Xeon E3-1245 v5 was doing great and in this article are more raw performance benchmarks comparing it to other Skylake and Haswell hardware, including some power and performance-per-dollar metrics.
As a reminder, the Xeon E3 1245 v5 is a quad-core processor with Hyper Threading to yield eight threads. The base frequency of this newly-launched CPU is 3.5GHz with a turbo frequency of 3.9GHz. This 80 Watt TDP processor also features Intel HD Graphics P530, has an 8MB cache, and supports the other features common to Intel's Skylake processors. This processor sells for just over $300 USD.
The motherboard used for the Xeon E3 1245 v5 system was a Supermicro X11SAE-M with Intel C236 chipset and has been working out fine under Linux.
Over the week of testing this Intel Xeon system so far, my only gripe has been about the HD Graphics P530 Linux support as it wasn't baked quite in time for Linux distributions to ship for providing a pleasant out-of-the-box experience. With Ubuntu, workarounds were needed to drive the display and to upgrade to Linux 4.3+ if you want accelerated graphics and working mode-setting. Fedora 23 doesn't yet have support for the HD Graphics P530 and CentOS 7 1511 also goes without the graphics support. But on the processor side, everything has been smooth sailing.
The processors used for this comparison against my lone Skylake Xeon system included:
- Intel Core i5 6600K Skylake
- Intel Core i5 6500 Skylake
- Intel Pentium G4400 Skylake
- Intel Xeon E5 2687W v3 Haswell
- Intel Core i7 5960X Haswell-E
They are just a selection of modern Intel processors I had available for testing. In the earlier Xeon Skylake system build article is a more diverse range of Intel and AMD systems tested if interested. All of these Haswell/Skylake systems were running Ubuntu 15.10 with the Linux 4.4 kernel, Mesa 11.2-devel, and the GCC 5.2.1 compiler.
