Funny this one. TSMC has announced that AMD EPYC processors are now powering workloads for its global microchip manufacturing business. The company not only fabricates wafers but is also heavily eng... TSMC uses AMD EPYC processors to fab EPYC and Ryzen processors
Good thing they're using single-socket 24-core models. Those are probably the most undesirable chips of the modern Epyc lineup. Everyone else is either going to want dual-socket 64c models, single-socket 8c models (mostly for all those PCIe lanes), or opt for Threadripper.
I don't know why any company even slightly dependent on computer processing performance would deliberately choose a lower-performing, often more expensive alternative to EPYC. Seems only logical to use EPYC.
