Привіт, Слава Україні!

I'm from New Zealand (and live there again now), but I've traveled in Ukraine a little, including Dnipropetrovsk (as it was still called at the time in 2014), previously I believe the largest "closed city" in the USSR and the place a lot of aerospace technology was made. The other previously closed city I've been to is Chernogolovka, not far (20km) from "Starry City". My ex-gf (1996-2004) grew up in Chernogolovka before moving to NZ in 1994, her parents were chemical engineers there. Now the town is perhaps best known for a line of soft drinks.

I worked on compilers & JITs for Samsung R&D in Moscow from July 2014 to March 2018, living there from April 2015. I visited old friends/colleagues there at New Year 2020.

I don't intend to visit Russia again any time soon, for obvious reasons, but I'm thinking about spending some time in Odesa (and spending my remote-working salary there) as soon as it is practical.

I've been following democracy in Ukraine, and the fight against the left-over USSR culture of corruption, for a long time. Here's a video I captured (at home in NZ) from a webcam in Ukraine showing my friend Natalia voting in Kryvyi Rih (where I spent a week in 2014) in the October 2012 elections.

Ok, that's a very long diversion from the topic. Just want to show I didn't suddenly become an expert on Ukraine or Russia or UA/RU relations on February 24 2022 )))

> Systems, you mentioned, are from my view, something in best case 2017 year desktop technology on steroids for West

The SG2042 is very much like the Graviton 1 that went into production (A1 instances) at AWS in November 2018, just over five years ago. The biggest difference is the SG2042 has 64 cores while the Graviton has 16. The C910 and A72 cores are very similar designs.

Note that the RISC-V instruction set did not yet officially exist until July 2019, and it takes around five years to design a CPU core and get it into a chip in a system, you can buy.

MUCH faster RISC-V SBCs using the SG2380 are coming out late this year, at Arm A78 level. That doesn't exist yet in Arm SBCs. The first A76 RK3588 boards were in around May 2022, and the Raspberry Pi 5 arrived at customers in bulk only around 2-3 months ago.

When the SG2380 arrives later in the year RISC-V will be less than 2.5 years behind ARM.

Sure, both are behind Intel and AMD at present. That's going to change by about 2026. There are multiple companies in the USA with Apple M* level RISC-V chips under development, several of them employing senior ex-Apple designers, and all of them with a lot of people with recent Intel and AMD experience.

Btw, I also have access to an Elbrus, which I've experimented with, so I've got some idea about them too. I also had many colleagues at Samsung who previously worked on Elbrus compilers at MCST.

I've also seen Mt Elbrus with my own eyes (but haven't climbed it!), from Pyatigorsk (and the top of Beshtau, 95km), from the top of Dombay ski lifts (60km), and from somewhere on A157 (50km)
