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] The processor's architecture allows support of up to 32 processors on a single server motherboard.[5][6]

In 2018 MCST announced plans to produce Elbrus-8SV an upgraded version of the 8C but with doubled performance. 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] Development was ended at 2019[8] and it's fabrication started at 2020.

Supported operating systems

The Elbrus-8S and -SV processors support binary compatibility with Intel x86 and x86-64 processors via runtime 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.
