Dual amd epyc 7601 processor performance and review part 1 electricity kwh cost

###########

Today we are going to launch Part 1 of our performance series on the dual AMD EPYC 7601 series processors. electricity and magnetism online games This is going to be the first of a multi-part series. For those wondering why we discussed a bit in our AMD EPYC Infinity Fabric Latency DDR4 2400 v 2666: A Snapshot piece but we have been waiting for our test platforms to mature to the point that we feel confident that our numbers will resemble what our readers will see if they buy systems.

With that said, our expanded benchmark suite runs are automated but take 10+ days to run, especially with the higher-end applications. We also wanted to get enough data we could use to compare systems that will compete in the marketplace. Comparing a $10,000 Intel Xeon Platinum and a $4,200 AMD EPYC CPU is not something that is overly useful since they are focused on different market segments. Every day that goes by we are collecting a significant amount of data on AMD and Intel platforms, but this process does take time. gas laws worksheet pdf Just to give our readers a sense, at any given time we are now using about 10kW in the data center testing this new generation of gear.

The AMD EPYC 7601 is a great chip and an absolute monster in terms of raw specs. It has 32 cores, 64 threads. electricity and magnetism review game L3 cache measures 64MB. There is a total of eight DDR4-2666 memory channels capable of two DIMM per channel configurations or up to 2TB per CPU. PCIe lanes abound with 128x (1P) 64x (2P) I/O lanes per CPU that can be used for PCIe or SATA III. electricity dance moms Let us be clear, on a platform level, the AMD EPYC 7000 series is simply awesome.

We also wanted to make a few notes that we thought warranted discussion. First, we do have some professional application benchmarks that run on CentOS/ RHEL. electricity videos for 4th grade We use CentOS 7.3 but with EPYC, we are going to suggest upgrading the kernel. Likewise, Ubuntu 16.04 is the current LTS release but we suggest using Ubuntu 17.04 “Zesty” or upgrading the kernel to 4.10 or later if you must use 14.04 LTS or 16.04 LTS. Our general policy is to use standard Ubuntu LTS and CentOS releases but AMD EPYC is getting more performance from newer software ecosystems. electricity production by state This is normal and we expect EPYC to get performance gains as software optimizes for the new CPU architecture.

Overall, strong results. We are going to delve more into power consumption as we do the system review since chassis cooling, power supplies and platform configurations make such a big difference in today’s overall server power consumption. These numbers are directionally correct which should provide a sense of power consumption of the platform.

indeed they have begun to push the maximum bandwidth in the last years, but have a look at the bandwidth/flop we had with the release of QDR Infiniband and compare that to the numbers we have now. The same with latency, the big jump came from the integration of the pci-e directly into the cpu not from going from QDR to FDR. Have also look at the bandwidth profiles ( http://mvapich.cse.ohio-state.edu/performance/pt_to_pt/): if your application cannot use large enough data chunks, you simply don’t notice the faster interconnect at all and this is really a problem because taking a given problem-size and scaling it to several nodes usually ends up in smaller and smaller data chunks to send around. I think it might be changing with the new competition from Intel to Mellanox. And if you really want to pay for a dual/multi-rail network two single port cards, one for each cpu, is the way to go, otherwise you mess up your inter socket bandwidth and also the latency for the remote cpu is higher in the dual port option.
