TSMC produces chips for AMD, but it also now uses AMD's processors to control the equipment that it uses to make chips for AMD (and other clients too). Sounds like a weird circulation of silicon, but that's exactly what happens behind the scenes at the world's largest third-party foundry.
There are hundreds of companies that use AMD EPYC-based machines for their important workloads, sometimes business-critical workloads. Yet, when it comes to mission-critical work, Intel Xeon (and even Intel Itanium and mainframes) rule the world. Luckily for AMD, things have begun to change, and TSMC has announced that it is now using EPYC-based servers for its mission-critical fab control operations.
"For automation with the machinery inside our fab, each machine needs to have one x86 server to control the operation speed and provision of water, electricity, and gas, or power consumption,” said Simon Wang, Director of Infrastructure and Communication Services Division at TSMC.
“These machines are very costly. They might cost billions of dollars, but the servers that control them are much cheaper. I need to make sure that we have high availability in case one rack is down, then we can use another rack to support the machine. With a standard building block, I can generate about 1,000 virtual machines, which can control 1,000 fab tools in our cleanroom. This will mean a huge cost saving without sacrificing failover redundancy or reliability."
It is noteworthy that AMD's data center products are used not only to produce chips, but also to develop them. AMD's own Radeon Technologies Group uses EPYC processors to design GPUs.
