Elbrus CPU Review

Cannot tell if this video is true to life:

Anyone knowledgeable in CPU design, please help

Tldr, still 2-3x slower than similarly sized 5nm CPUs on non-optimized C++ code, but it works, which is a miracle.

On optimized code it can be 10x faster, but there is very little such code.

Java and Python are obviously not supported.
