Most interesting comparison to date for 8 way Linux distro compare 8-Way Linux Distribution Comparison On A Dual Xeon Scalable Gold Server - Phoronix

This is our look at the most interesting enterprise-focused Linux distribution comparison to date as we see how Intel's Xeon Scalable platform compares on different GNU/Linux distributions when using the Tyan GT24E-B7106 paired with two Dual Xeon Gold 6138 processors. The tested configuration has 96GB of DDR4-2666 memory and 40 cores / 80 threads to see how different modern Linux distributions are affected with the latest-generation Xeon platform.

The tested distributions included:

Antergos 17.8 - While Arch/Antergos is still making more inroads for servers/workstations, there are many Phoronix readers always curious about numbers on this side... Antergos currently has Linux 4.12 with GCC 7.1.1 atop EXT4.

Cent OS 7 - For some EL7 coverage we used CentOS 7 with its Linux 3.10 kernel, GCC 4.8.5 compiler, and XFS file-system.

Clear Linux - Intel's own Linux distribution, Clear Linux, which tends to always be optimized for delivering the greatest open-source performance possible on Intel hardware. Clear Linux 17210 has the Linux 4.12 kernel, GCC 7.2.0, and uses an EXT4 file-system.

Debian 9.1 - Debian Stretch has the Linux 4.9 kernel, GCC 6.3.0, and an EXT4 file-system.

Fedora 26 - If you are trying to get an idea where Red Hat's enterprise Linux performance is heading in the future, there is the latest Fedora release. Fedora 26 currently has the Linux 4.12 kernel and GCC 7.1.1 while using EXT4.

Ubuntu 16.04.3 LTS - The latest Ubuntu Long Term Support release for servers with its hardware enablement stack has Linux 4.10 while using the older GCC 5.4 compiler and of course is still on EXT4.

openSUSE Leap 42.3 - For getting some numbers in line with SUSE Linux Enterprise Server given Leap is built from the same code-base... That means Linux 4.4, GCC 4.8.5, and XFS.

openSUSE Tumbleweed - The rolling-release version of openSUSE is onto using Linux 4.12, GCC 7.1.1, and XFS.

All eight of these tested Linux distributions had worked fine out-of-the-box with the Tyan GT24E-B7106 and did not run into any compatibility problems or anything along those lines.

Interesting note Intel Skylake Omni-Path Fabric Does Not Work on Every Server and Motherboard

With the launch of Intel Xeon Scalable Intel added an intriguing new feature: Omni-Path fabric. We touched upon the feature during the SKU list and architecture discussions for Skylake. Essentially, Intel is launching “F” SKUs with Integrated Omni-Path fabric. The F SKU variant is interesting for two reasons. First, it adds 100Gbps fabric for only $155 or so per CPU when compared to non-F variants. Second, this 100Gbps fabric does not take any of the standard 48x PCIe 3.0 lanes. Instead, Intel Xeon Scalable F SKUs have an additional PCIe x16 link for this fabric making the effective total PCIe lanes per CPU 64. What we did not realize is that the fabric enabled parts do not work in every server and motherboard for the Intel Xeon Scalable family.

More Intel Xeon Scalable cpu benchmarks from STH Intel Xeon Silver 4114 Linux Benchmarks and Review

The Intel Xeon Silver 4114 is the second highest SKU in the Intel Xeon Scalable Silver range. With 10 cores and modest clock speeds its closest relative in the Intel Xeon E5 V4 generation would be the Intel Xeon E5-2630 V4 or perhaps the Xeon E5-2630L V4. Priced at a 40% or so premium to the Intel Xeon Silver 4110 and Xeon Silver 4112, one gets a major benefit: this is the lowest cost 10 core CPU in the Xeon Scalable lineup. With that said, it brings into sharp focus the Intel pricing deltas in the Skylake-SP generation.

Key stats for the Intel Xeon Silver 4114: 10 cores / 20 threads, 2.2GHz base and 3.0GHz turbo with 13.75MB L3 cache. The CPU features a 85W TDP. This is a price point Intel has maintained for years. Here is the ARK page with the feature set.

Amazon EC2 instances with Xeon Scalable processors Amazon AWS EC2 C5 Instances with Custom Intel Xeon Scalable CPUs

Amazon AWS EC2 C5 instances are powered by 3.0GHz CPUs with a max single core turbo boost of 3.5GHz. At the time of this writing, Intel has three listed CPUs with that base clock, the Intel Xeon Platinum 8158, the Gold 6154 and Gold 6136. All three CPUs have a 3.7GHz max turbo frequency. Intel and Amazon did not comment on the model number as they have done with previous generations.

pricey though

Intel Xeon Platinum 8158 v Intel Xeon Gold 6136 Differences

We were recently running some tests in our lab on two SKUs, the Intel Xeon Platinum 8158 and the Intel Xeon Gold 6136 to investigate exactly what the differences are. On paper, the chips look almost exactly the same but the Intel Xeon Platinum 8158 is almost three times the price. What we found was that the main driver of price comes down to a niche feature that reinforces our belief that the Intel Xeon Platinum line is not targeted at the same market as AMD EPYC for comparison purposes.
