Leading CPU makers AMD and Intel left the Russian market after Russia invaded Ukraine in late February, and right now it is not easy for Russian PC makers to obtain the chips they need.
There are several Russian companies that design their own processors, but those chips are made by TSMC, and Taiwan no longer allows their export to Russia. As a result, the country cannot replace foreign CPUs with its own, reports Kommersant business daily.
Russian makers of PCs and servers this year reportedly supplied just 15,000 PCs and 8,000 servers based on Elbrus and Baikal processors designed in Russia and then fabbed in Taiwan, according to Russia's Ministry of Digital Development, Communications and Mass Media.
"We would have a lot more [PCs and servers based on Russian CPUs] this year if those batches of Russian processors, Elbrus, Baikals, which were ordered and produced, were shipped," said Maksut Shadayev, the head of the ministry. "Intellectual property and all documentation are Russian, but there are no production facilities in Russia that could produce those CPUs, which is why production was ordered in other countries."
The most advanced fab in Russia can produce chips on a 90nm node, whereas MCST's most sophisticated CPUs were made by TSMC on its 16nm fabrication process.
Due to restrictions imposed on high-tech exports to Russia by the United States, United Kingdom, and the European Union, leading Taiwanese companies were among the first to cease working with Russia after the country started a war against Ukraine several months ago.
In June, Taiwan's Ministry of Economic Affairs (MOEA) officially issued its list of high-tech products that are barred from shipping to Russia and Belarus in a bid to not allow the countries to use advanced technology for military purposes. In particular, Taiwan authorities banned exports of processors that have performance of over 5 GFLOPS, operate at 25 MHz or higher, feature an external interconnection with a data transfer rate of 2.5 MB/s or over, and/or have an ALU that is wider than 32 bits. Essentially, Taiwan does not allow exports of advanced processors to Russia, so TSMC cannot ship the chips was contracted to produce for the country. And TSMC isn't the only company that can't or won't ship chips to Russia.
"Foreign manufacturers that produce processors based on blueprints of Russian developers refused to fulfill orders in 2022, including shipping already produced chips," said Shadayev, reports RBC.
Intel 486 800nm btw
The first 90nm chips came out 2002 and were eDRAM and flash (easier to do than processors), the first wave of processors to use 90nm came out in 2004, specifically Intel Prescott (3rd gen Pentium 4), AMD Winchester (3rd gen Athlon 64) and IBM 970FX (2nd gen G5) in no specific order.
All these were still single-core processors but had on the order of 50-100 times as many transistors in them as the 80486!
The first 65nm processors came out in 2006 but the changeover is a very gradual process with an extremely long "tail", processes keeps being used almost forever in the embedded space, IIRC you can still order at least up to 600nm! chips, probably way higher too.
Much of military hardware relies on and is built around technologies going far back as 80's. It is not uncommon to see "old" motorola or intel cpus in everthing from cruise missiles to jet fighters. For example the two main cpus of F22A Raptor are variants of Intel i960MX originally launched in 1984. Even modern civilian aircraft such A320,330 or even 380 have their flight management system based around licensed variants of Am29000 series from AMD which was released all the way back in 1988.
Worse, they're still on Windows ME
Edit: Nefarious plan, we offer them a windows upgrade....to Vista!
Heck in theory kalashs's commerce is forbidden too, but this rifle is everywhere in 3rd world countries. I bet CPUs are easier to smuggle than assault riffles
Yeah, I remember that too. 486 DX266 was the PC I used when I was 8 or so. My college PC was 90nm, those were quite far apart.
