Does Elbrus count?

Supporting 16TB of RAM is pretty impressive actually.

Support for 16 TB of RAM is not impressive at all, actually. It just means that that the memory address bus is 46 bits wide. For comparison, AWS has offered 24 TB servers since 2019 based on Intel Xeon for SAP HANA in-memory databases: https://aws.amazon.com/blogs/aws/ec2-high-memory-update-new-...

That Russian CPU is also PCIe 3.0 in an era where PCIe 5.0 is becoming the standard. Similarly, DDR4 in the DDR5 era.

Can they manufacture these in volume? With good yields? Can they keep it up even if nobody will sell them chip fab machines and parts?

It would be, if it worked.

Wow, I haven't heard of these "catastrophic failures" previously... that's a bummer.

The previous generation certainly worked.

Is there an article that explains this in more technical detail?

I’d call it a lucky accident, given the context - Russia would be harder to defeat otherwise. As for reasons - I’m guessing the usual, nobody wants to work on this, because pay is crap and, well, and I’m guessing many folks don’t want to work for nazis. That’s also why Russia can’t manufacture tanks anymore.
