AMD is having some of its latestRyzen9000-series desktop CPUs made at TSMC’s new fab in Arizona. So claims Taipei, Taiwan-based journalistTim Cuplan. It was reported last year that AMD was planning on having somehigh-performance CPUs made at TSMC’s Arizona facilities. Now those CPUs have been identified as the latest Ryzen 9000 models and they are said to already be in production.

However, the broader context for this news is quite complicated. TSMC is on record as saying that chips in its Arizona fab cost more to make than equivalent products in is factories in Taiwan. It also says that it plans to charge more for US-made chips as a consequence.

Moreover, AMD Ryzen 9000 CPUs are chiplet designs. While it seems AMD is now having some 8-core CPU dies made in Arizona, the package also contain a 6nm I/O die housing the memory controller and other functionality.

That die, as we understand it, is still made in Taiwan. TSMC does have an older fab in Washington state. But that facility at best produces chips on the 16nm node.

Indeed, there are further components in the package and then the package itself to consider. It’s not clear where all of the items are produced. So, the mere fact of Ryzen 9000 CPU dies being made in the US wouldn’t automatically into an all-American product, even if the CPU cores themselves will have been both designed and manufactured in the USA.

AMD is now reportedly manufacturing 4nm Ryzen 9000 CPU chiplets in Arizona, less than a year after the chips were first launched.(Image credit: Future)

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.

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 evenAMD’s new RDNA 4 GPUswhich were almost but not quite announced at CES are still on N4.

The same goes forNvidia’s latest Blackwell RTX 50 graphics chips. 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.
