The Elbrus-8S (Template:Lang-ru) is a Russian 28 nanometer 8-core microprocessor under development by Moscow Center of SPARC Technologies (MCST). The first prototypes are projected to be produced by the end of 2014 and serial production is set to start in 2015. The Elbrus-8S is to be used in servers and workstations.[1]

Four Elbrus processors on a server motherboard puts a total of 32 processor cores in a server blade.[2][3]

In 2018 MCST announces 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.[4]
