Sounds like it's more of a research/development thing than an actual commercial chip. Obviously I can't read russian or anything, just that from the specs it feels like something to prove that the instruction set runs well and can handle x86 programs out of the box and then they can look at improving the fab process, speed and core count once that's done. That would actually make sense.
If it's not then I have no idea what's the point of this at all. As others have said, there's no reason why they couldn't use an off the shelf ARM design with their own modifications which would be both cheap and radically easier to develop for. ARM might not be hyper popular in the desktop space but there's certainly lots of talent working on ARM chips and a solid amount of software too. A far better option than going propitiatory would be for Russia to throw their chips behind ARM as a desktop/server chip set - that would actually stand a chance of success.
I guess we wait and see, but just from the article this seems like an interesting but ultimately useless piece of hardware; a solution in search of a problem. You can certainly do a lot more with 800mhz these days than people think (especially on linux - plenty of office machines would happily run on that), but if you can manage on 800mhz then you can manage on an 800mhz ARM chip without even touching x86 software.
