The Elbrus 2000 is rather fascinating, but they can't even make them anymore. Perhaps the older models, but the newer ones where all manufactured by TSMC, and Russia doesn't have the ability to create anything below 90nm.
There was an article about some Russian bank testing out the e2k, but they reported that the Elbrus-8C, was not acceptable. The 8C is 28nm, so made by TSMC, so even if it could perform it would be available.
I'm still curious about the chip though.
- kragen 3y agothe slow death of elbrus is a very sad story, similar to the usa's efforts to revive its interplanetary space travel program

- ogurechny 3y agoSberbank testing seems to be blown out of proportion by Wikipedia-studying analysts. Or someone else, for some other reason. It's easy to guess that certain “patriotic” circles had decided to make Sberbank support the production by signing some big long term contract, and they decided to NOPE out of it, and quickly made a critical assessment in comparison with top of the line commercial offers. Effective performance of Elbrus in various tests was neither a secret nor a surprise. The problem isn't performance, it's the architecture. Supposedly, it's intended use case is being a processor for radar control systems with lots of floating point number-crunching/DSP/whatever power to process input data in real-time and also run some general purpose code based on results, all in a single package. Other tasks rarely need that combination of features, it's either top general purpose performance on x86 servers, or top number crunching performance on supercomputers.

Unfortunately, VLIV compilers must be very smart, and ingest all the software and hardware optimizations from others to compete with common architectures.
