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.[1] The Elbrus-8S is to be used in servers and workstations.[2] The processor's architecture allows support of up to 32 processors on a single server motherboard.[3] [4]

In 2018 MCST announced plans to produce the Elbrus-8SV, an upgraded version of the 8C with doubled performance. The CPU can process 576 Gflops and has a frequency of 1.5 GHz, as well as DDR4 support instead of DDR3. Engineering samples were already completed in Q3 2017.[5] Development was completed in 2019[6] and its fabrication started in 2020.

In 2021 the processor was offered to Sberbank, Russia's largest bank, for evaluation in light of a potential use for some of the company's hardware needs. The evaluation had a negative outcome, as the functional requirements were not met.[7]

2023 benchmark demonstrated that the Elbrus-8SV performed moderately in gaming with games that were 10 years old but was incompatible with modern games tested.[8]

Successor Elbrus-16C was announced in 2020 with declared start of manufacturing in October 2021[9] but hasn't entered the market as of 2023 yet.

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.
