A report that it was a bargain with good cost performance when I bought the mysterious AMD server CPU 'EPYC 7C13'

AMD's '

AMD EPYC 7C13 ' is priced around $2,000 (approximately 300,000 yen), which is a low price for a CPU for servers, but it achieved excellent results in load tests, according to technology media Serve The Home. reports.

AMD EPYC 7C13 is a Surprisingly Cheap and Good CPU

Serve The Home discovered a server equipped with a CPU called ``AMD EPYC 7C13'' that I had never seen before on the mail order site Newegg, and immediately purchased several servers and tested their performance.

When displaying CPU information using

the lscpu command , it was found that the AMD EPYC 7C13 is based on the ` `AMD EPYC 7003 '', a 3rd generation EPYC processor with 64 cores and 256MB of L3 cache.

Furthermore, when executing

the dmidecode command to display hardware information, it became clear that AMD EPYC 7C13 can convey information to the OS at a maximum speed of 3700MHz.

AMD's page lists the official specifications for AMD EPYC 7C13, and AMD EPYC 7C13 can lower the thermal design power (TDP) to 165W, just like Intel Xeon processors up to 2017.

Since AMD EPYC 7C13 is not in general circulation, Serve The Home speculates that ``some functions may be locked.'' However, when I installed the virtualization platform ' Proxmox VE 8.1 ' on my AMD EPYC 7C13, it ran without any problems.

Additionally, Serve The Home ran

the stress-ng command to see how it behaves under stress on an AMD EPYC 7C13. As a result, it was reported that the CPU clock fluctuated in the range of 2.42 to 2.43 GHz, and although the power consumption temporarily exceeded 230W, it basically remained at around 225W.

In addition, when Serve The Home installed an AMD EPYC 7C13 on a server equipped with 512GB of memory, a network interface card compliant with the OCP 3.0 standard, and two PCIe Gen4 NVMe SSDs with a capacity of 3.84TB, it found that it was idle. The power consumption in the state was 83.3W, and the power consumption in the maximum load state was only 333.3W.

This result was almost identical to the 16-core

Intel Xeon E5-2600 v4 . However, since Intel Xeon E5-2600 v4 is for dual socket servers, AMD EPYC 7C13 is a single socket, so AMD EPYC 7C13 has higher actual performance and power consumption.

Also, according to Serve The Home, the commonly distributed product that is closest to the configuration of AMD EPYC 7C13 is AMD EPYC 7713P , but the list price of this product is relatively high at $ 5,000 (about 750,000 yen). . Therefore, the EPYC 7C13, available for just $2000, could be another choice when choosing a data center CPU.

Serve The Home says of the AMD EPYC 7C13, ``If you can get your hands on this CPU, it's a great value for people who want to replace traditional server parts with new parts, but also want to do it as cheaply as possible. It could become something.”
