AMD --
Yesterday a new batch of AMD EPYC processors arrived for testing at Phoronix.

Thanks to AMD for sending out some additional EPYC processors for Linux testing as well as TYAN for their platform support.

To complement our existing AMD EPYC testing with the EPYC 7601 is now the:

EPYC 7251 - The lowest-end EPYC part an 8 core / 16 thread server processor for just under $500 USD while having a 2.1GHz base frequency and 2.9GHz peak frequency. This is the lone EPYC CPU right now having only DDR4-2400 support rather than DDR4-2666, but still supports eight memory channels.

EPYC 7351P - The 7351P is a $750 USD CPU that boasts 16 cores / 32 threads, 2.4GHz base frequency, and 2.9GHz boost frequency. There's a lot of value with the 7351P especially in comparison to the current Xeon Scalable line-up.

EPYC 7401P - The EPYC 7401P boasts 24 cores / 48 threads with 2.0GHz base frequency and 3.0GHz maximum boost frequency. This CPU goes for just over $1000 USD and should be another interesting test candidate.

EPYC 7551 - A step below the EPYC 7601. This $3400 USD processor is a 32-core / 64-thread CPU while having a base clock of 2.0GHz and clocks up to 3.0GHz. Like the 7601, it's a 180 Watt TDP part, 64MB L3 cache, etc.

Full reviews and benchmarks on these four more EPYC processors will be published in the days ahead plus many other interesting EPYC Linux tests (and I happen to be finishing up EPYC 7601 BSD tests right now as well) over the coming weeks.

Part of the purpose of this notice is also to solicit any other test/workloads you'd like to see benchmarked with these EPYC processors. Aside from the many benchmarks ran already, if there are any other workloads of interest to you, be sure to let me know right away. If they are not already part of the tests on, be sure to link / provide reference to any documentation for being able to run the tests in an automated, default sane manner... Or ideally a bash script already to start from, considering I am not a domain expert on everything as well as being a time saver, any helpers are useful in being able to ensure coming up with good real-world tests. Basically if the test is multi-threaded and can easily be run in a standardized manner, happy to add it to the test queue for these processors. Or any other EPYC test requests, feel free to post away on the forums or via Twitter; of course, if you are a Phoronix Premium supporter, you should already know my email to personally contact me with any benchmark requests and feedback.
