Elbrus-8S

The Elbrus-8S (Russian: Эльбрус-8С) is a Russian 28 nanometer 8-core microprocessor developed by Moscow Center of SPARC Technologies (MCST). The first prototypes were produced by the end of 2014 and serial production started in 2016.[3] The Elbrus-8S is to be used in servers and workstations.[4]

Four Elbrus processors on a server motherboard puts a total of 32 processor cores in a server blade.[5][6]

In 2018 MCST announced its plans for the production of an updated version with twice the performance, the Elbrus-8SV. The CPU features 576 Gflops and 1.5 GHz, as well as DDR4 support instead of DDR3.[1][2] Engineering samples were already completed in Q3 2017.[7]

Supported operating systems

The Elbrus-8S and -SV processors support binary compatibility with Intel x86 and x86-64 processors via binary translation.[2] The documentation suggests that the processors can run Windows XP and Windows 7.[2] The processors can also run a Linux kernel based OS compiled for Elbrus.

gollark: Here is your next ethical question. What do you do, as an ethics person who is ethical?
gollark: What is the most ethical thing to do in this situation?
gollark: I guess I win against Luca and Kc5f, and draw against Lemmmy.
gollark: Well, they all check out.
gollark: `DxzPEFimIU paper` (I'm using SHA256, of course).
