Gigabyte R272-Z32 Performance
For this exercise, we are using our legacy Linux-Bench scripts which help us see cross-platform “least common denominator” results we have been using for years as well as several results from our updated Linux-Bench2 scripts. Starting with our 2nd Generation Intel Xeon Scalable benchmarks, we are adding a number of our workload testing features to the mix as the next evolution of our platform.
At this point, our benchmarking sessions take days to run and we are generating well over a thousand data points. We are also running workloads for software companies that want to see how their software works on the latest hardware. As a result, this is a small sample of the data we are collecting and can share publicly. Our position is always that we are happy to provide some free data but we also have services to let companies run their own workloads in our lab, such as with our DemoEval service. What we do provide is an extremely controlled environment where we know every step is exactly the same and each run is done in a real-world data center, not a test bench.
We are going to show off a few results, and highlight a number of interesting data points in this article.
Python Linux 4.4.2 Kernel Compile Benchmark
This is one of the most requested benchmarks for STH over the past few years. The task was simple, we have a standard configuration file, the Linux 4.4.2 kernel from kernel.org, and make the standard auto-generated configuration utilizing every thread in the system. We are expressing results in terms of compiles per hour to make the results easier to read:
We are seeing some other platforms that are more suited to lower-end AMD EPYC offerings. With a full set of 16 DIMM slots and all of the storage I/O, we think that the AMD EPYC 7702P, EPYC 7502P, and EPYC 7402P will be popular in the Gigabyte R272-Z32. Gigabyte’s platform allows one to fully utilize the feature set of these AMD CPUs to use a lot of cores, RAM, and I/O.
c-ray 1.1 Performance
We have been using c-ray for our performance testing for years now. It is a ray tracing benchmark that is extremely popular to show differences in processors under multi-threaded workloads. We are going to use our 8K results which work well at this end of the performance spectrum.
We wanted to take a quick pause and note the enormous performance delta that these processor options have. They range from an 8 core $450 CPU to a 64 core $7000 CPU.
7-zip Compression Performance
7-zip is a widely used compression/ decompression program that works cross-platform. We started using the program during our early days with Windows testing. It is now part of Linux-Bench.
As some perspective here, the Intel Xeon Platinum 8280 and Platinum 8276L SKUs we tested will fall between the 24 core AMD EPYC 7402P ($1250) and the AMD EPYC 7502P ($2300.) You will need two Intel Xeon CPUs to run a 24-bay NVMe system like the Gigabyte R272-Z32.
OpenSSL is widely used to secure communications between servers. This is an important protocol in many server stacks. We first look at our sign tests:
Here are the verify results:
With the AMD EPYC 7002 series, AMD again is pushing its single-socket value proposition by offering “P” SKUs. These “P” SKUs offer a substantial discount over non-P parts and as a result, we see the AMD EPYC 7702P being a much more common option in the Gigabyte R272-Z32 than the EPYC 7742.
UnixBench Dhrystone 2 and Whetstone Benchmarks
Some of the longest-running tests at STH are the venerable UnixBench 5.1.3 Dhrystone 2 and Whetstone results. They are certainly aging, however, we constantly get requests for them, and many angry notes when we leave them out. UnixBench is widely used so we are including it in this data set. Here are the Dhrystone 2 results:
Here are the whetstone results:
From a raw CPU performance perspective, the single AMD EPYC 7702P and EPYC 7742 configurations are competitive with dual Intel Xeon Platinum 8280/ Platinum 8276 systems.
Chess is an interesting use case since it has almost unlimited complexity. Over the years, we have received a number of requests to bring back chess benchmarking. We have been profiling systems and are ready to start sharing results:
AMD has a very strong single-socket value proposition. We went over the market impact of their revolutionary architecture in AMD EPYC 7002 Series Rome Delivers a Knockout. The other key item to keep in mind when configuring the Gigabyte R272-Z32 is that the entire platform can run using a single CPU. Depending on your software-defined storage application, NIC being used, and workloads you may want to run on the platform, you have a fairly wide range of CPU options from AMD. We focused on the five AMD EPYC “P” series parts and two others that we think may make sense in a single-socket configuration like the Gigabyte R272-Z32.
Next, we are going to cover storage performance and power consumption before getting to our final words.
