The Elbrus-8S (Russian: Эльбрус-8С) is a Russian 28 nanometer 8-core microprocessor under development 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]

Four Elbrus processors on a server motherboard puts a total of 32 processor cores in a server blade.[3][4]

In 2018 MCST announced its plans for the production of an updated version with twice the performance, the Elbrus-8SV. The CPU features 500 Gflops and 1.5Ghz,as well as DDR4 support instead of DDR3. Engineering samples were already completed in Q3 2017.[5]
