    A new computer production facility based on Russian Elbrus processors has been launched in the Moscow region


    They refer to 25,000 servers and 320,000 desktop class (including workstation) computers every year. Not too shabby.

    Except Elbrus 8SM and newer (Elbrus 1SM, Etc) are 28nm and Elbrus 16 is also 14nm or so. But all TSMC built. Military ones are built locally but on 65nm.

    Yes, the Elbrus-16S requires 16 nm lithography.

    I looked at http://mcst.ru/elbrus-8sv and they doubled the FP performance by increasing the SIMD register width from 64 to 128 bits.
    This required and increase of transistors from 2.73 to 3.5 billion without any changes in cache size.   The same instruction latency
    was retained.   This is a rather small number of transistors for such a big gain in performance.   I would think that using 256 and
    eventually 512 bit SIMD register widths would be rather feasible and not outlandish.

    So an Elbrus-MAX with 512 bit SIMD registers would be around 10 billion transistors.   The only cost is die size
    and heat.   A die shrink from 28 nm to 14 nm would be the right move.   So instead of 288 Gigaflops for FP64 we would
    have over 1500 GFlops if the clock can be increased with a smaller lithography process.   This would make the Elbrus-16
    a leading design in terms of FP.
