ELBRUS MCST History

Before we look at the IcepeakITX ELBRUS-8CB motherboard lets first look at the history of Elbrus.

Elbrus CPU’s have been around for a very long time although unless you’re from Russia you’ve likely never heard of them.

They were first released in the early 1970’s and used in the Soviet space program, nuclear weapons research and defence systems as well as for research.

Elbrus Timeline

  • Elbrus 1 (1973) was the first in the line.
    • A side development was an update of the 1965 BESM-6 as Elbrus-1K2.
  • Elbrus 2 (1977) was a 10-processor computer, considered the first Soviet supercomputer, with superscalar RISC processors. Re-implementation of the Elbrus 1 architecture with faster ECL chips.
  • Elbrus 3 (1986) was a 16-processor computer developed by the Babayan’s team, and one of the first VLIW computers in the world.
  • Elbrus 2000 (2001) was a microprocessor development of the Elbrus 3 architecture. Also known as Elbrus-S.
    • Elbrus-3M1 (2005) is a two-processor computer based on Elbrus 2000 microprocessor working at 300 MHz.
    • Elbrus МВ3S1/C (2009) is a ccNUMA four-processor computer based on Elbrus-S microprocessor working at 500 MHz.
  • Elbrus-2S+ (2011) working at 500 MHz, with capacity to calculate 16 GFlops.
  • Elbrus-2SM (2014) working at 300 MHz, with capacity to calculate 9.6 GFlops.
  • Elbrus-4S (2014) working at 800 MHz, with capacity to calculate 50 GFlops.[1]
  • Elbrus-1S+ (2016) SoC with GPU, working at 600–1000 MHz, with capacity to calculate 24 GFlops.
  • Elbrus-8S (2014–2015) working at 1300 MHz, with capacity to calculate 250 GFlops.
  • Elbrus-8SV (2018) working at 1500 MHz, with capacity to calculate 576 GFlops.
  • Elbrus-16S (2019) working at 2000 MHz, with capacity to calculate 1.5 TFlops.

Over the years Elbrus have used several different architectures including: SPARC, x86 and Elbrus 2000.
Back in 2014 ELBRUS released the Elbrus-4C CPU which was designed for home and office use within Russia. Performance wasn’t great and as it couldn’t fully support x86. Computers using the Elbrus-4C CPU shipped with a custom proprietary Linux distro named Elbrus OS. Little is known about the success of this platform and they are never seen in the western world. I tried to buy an Elbrus-4C computer and have it shipped from Russia to the UK back in 2015 and it proved impossible.

IcepeakITX ELBRUS-8CB Motherboard

The IcepeakITX ELBRUS-8CB Motherboard is the brain child of a group of enthusiasts that banded together to crowdfund a security focused Mini ITX motherboard featuring a 1.5GHZ 8 core Elbrus 8CB CPU and ships with either 8GB or 32GB DDR4 ECC RAM. The board does not ship with a heatsink however it is compatible with any heatsink designed for the Intel LGA3647 socket.

  1. It’s amazing to read an English blog about the Elbrus computer. Here is a link where you can buy an Elbrus computer. Price in rubles. That’s just over $ 4,000. You must understand that this price is justified because this is a computer exclusive.

    1. I’d love to get one to test out for this blog, unfortunately $4000 is way out of my price range although I’m hoping this particular board is way cheaper!
