Taiwan further restricts the sale of modern chips to Russia and Belarus

The Russian invasion of Ukraine shows no sign of ending anytime soon. Punishing sanctions haven't deterred Russia from its brutal war of aggression. These sanctions include denying Russia the use of advanced semiconductors, which it could use in support of its war. Taiwan's Ministry of Economic Affairs (MOEA) has announced a new list of technology items that are now banned from sale to Russia and its close ally, Belarus.

According to Digitimes(opens in new tab) (via The Register(opens in new tab)) the bans include pretty much any kind of processor made in the last 30 years. This means that Russia will find it increasingly difficult to source chips for its war operation, but beyond that, even chips for common items like smartphones, consumer electronics and vehicles will be difficult to attain.

According to Digitimes, the list of banned CPUs includes any model with the following features or characteristics:

To put this into perspective, Intel's i386 from the mid 1980s was introduced at 12.5MHz, reaching 40MHz by the late 80s. In terms of GFLOPs, a PlayStation 2 that debuted in 2000 is capable of 6.2 GFLOPs, though it runs at around 300MHz. This means that some processors from nearly 40 years ago would be banned. 

Russia does have its own semiconductor industry, though it's not exactly cutting edge. The Russian government said it wants to have 28nm manufacturing up and running by 2030, but with the current sanctions in place, almost all of its
