Elbrus-8S

The Elbrus-8S () 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. The Elbrus-8S is to be used in servers and workstations. The processor's architecture allows support of up to 32 processors on a single server motherboard.
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. Engineering samples were already completed in Q3 2017. Development was ended at 2019 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. The documentation suggests that the processors can run Windows XP and Windows 7. The processors can also run a Linux kernel based OS compiled for Elbrus.
