AMD is having some of its latest 9000-series desktop CPUs made at TSMC's new fab in Arizona. So claims Taipei, Taiwan-based journalist . It was reported last year that AMD was planning on having some . Now those CPUs have been identified as the latest Ryzen 9000 models and they are said to already be in production.
If true, that's an impressive win for TSMC's new US fab. It was only August last year that AMD released the Ryzen 9000, including the , using 4nm silicon for H25 com สล็อต the chip's CPUs made by TSMC's Taiwan factories, aslo known as the TSMC N4 node. So, moving some of that production to the Arizona fab so soon certainly looks like a vote of confidence in the facility.
As things standard, TSMC has three new Arizona fabs either already in production or being built. The first, FAB 21-1, produces 4nm chips reportedly including the AMD Ryzen 9000 and Apple's A16 and it already up and running. FAB 21-2 will up the ante to 3nm or N3 chips, the likes of which include Intel's Lunar Lake laptop CPU and are currently only made by TSMC in Taiwan, while FAB 21-3 will eventually make the move to 2nm.
For now, you can't actually buy any devices with TSMC-made 2nm or N2 silicon. Indeed, TSMC still plans to reserve its cutting-edge technology for its domestic Taiwanese plants. So, N2 chips made in Arizona will come online some time after similar silicon is available from Taiwan.
: The top chips from Intel and AMD.
: The right boards.
: Your perfect pixel-pusher awaits.
: Get into the game ahead of the rest.
That said, AMD doesn't tend to use the very latest nodes for its chips. The new Ryzen 9000 was rolled out on N4 despite TSMC having been in production with N3 for several years and even which were almost but not quite announced at CES are still on N4.
The same goes for . Those are on TSMC N4, too. So, the fact that TSMC's US fabs are being kept a step behind Taiwan doesn't mean we won't see new CPUs and GPUs that are made in the US.
Then again, the likes of AMD and Nvidia will have to play off the benefits of having chips made in the US, which might include avoiding tariffs, against higher local production costs. It'll be interesting to come back in five years or so and see which chips, exactly, end up being made in the US.
