The new chip targets the same market as AMD’s Epyc and Intel’s Xeon, although it's unlikely you’ll ever get your hands on one, because they are only produced for servers and PCs owned by the Russian government.
The 8CB is an 8-core CPU, with a clock speed of 1.5GHz and, because it uses an old 28nm manufacturing process, spreads its 2.8 billion transistors on a rather large 333mm^2 die - far bigger than similar processors that use processes as small as 7nm.
The 8CB isn’t that bad. It has peak double precision GFLOPS per core reaching 36. For context, the Fujitsu A64FX can manage 70.4 with a 50 per cent speed boost, while ARM's latest Cortex-X1 super core manages 48 with a 100% increase in clock speed.
The chip has gotten people wondering if Rostec managed to move to a finer node and achieve faster processing speeds and cram in more cores. It is pretty strange that they have not given any indication that they will shop outside mother Russia. Elbrus CPUs are compatible with x86 and x86-64 via Binary Translation without Intel’s IP, they could be a winner - especially with some countries aiming to minimise dependence on US technology.
