The original source does not claim that, it's a deformation from Tomshardware. Original claim [1]: > IFS is the only foundry to offer IP optimized for all three of the industry’s leading ISAs: x86, Arm and RISC-V. It's not the foundry that is "optimized for RISC-V & ARM & x86", it's the IP provided by the foundry services. This should be interpreted as: "IFS IPs (ARM & RISC-V & x86) are optimized for IFS fabs". And TSMC does not provide this service.
