US is no longer CPU empire. Elbrus-4C

The world is changing rapidly. I’m glad to announce that more and more alternative CPU appeared today. Since the leadership now belong to US companies like Intel and AMD, and British ARM, there is another release of newest Russian CPU – “Elbrus-4C”. It’s predecessor “Elbrus 2C+” was good enough for almost any real world needs, but this new “Elbrus-4C” is almost equal to modern desktop and server CPU the market leaders.

So, greetings to “Elbrus-4C”. But the way, the photo above may look confusing, where the name of the model is 2S, but this is the way the marketing named it, so it it not ”Elbrus-2S” but “Elbrus-4C”.

Looks really amazing. However the price and mass availability is still unclear. Following the rumors predecessor “Elbrus 2C+” was sold around state establishments and to military in Russia in numbers of 220 000 only. I think sales for the new Elbrus-4c will vastly increased, especially if US will implement the sanctions on Russia and will prohibit for leading CPU manufacturing companies to supply it’s products to Russia.
