TheElbrus-8S (Russian:Эльбрус-8С) is a Russian 28 nanometer 8-coremicroprocessor developed byMoscow 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 the Elbrus-8SV, an upgraded version of the 8C with doubled performance. The CPU can process 576Gflops and has a frequency of 1.5 GHz, as well asDDR4 support instead ofDDR3.[1][2] Engineering samples were already completed in Q3 2017.[7] Development was completed in 2019[8] and its fabrication started in 2020.
In 2021 the processor was offered toSberbank, 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.[9]
2023 benchmark demonstrated that the Elbrus-8SV performed moderately in gaming with games that were 10 years old but was incompatible with many modern games tested.[10]
Successor Elbrus-16C was announced in 2020 with declared start of manufacturing in October 2021[11] but hasn't entered the market as of 2023 yet.
The Elbrus-8S and -SV processors support binary compatibility with Intelx86 andx86-64 processors via runtimebinary translation.[2] The documentation suggests that the processors can runWindows XP andWindows 7.[2] The processors can also run aLinux kernel based OScompiled for Elbrus.
