Question: does anyone know whether the current generation of Google TPU uses PCIe 4.0 already? The POWER9 systems support PCIe 4.0 and last year Google confirmed they use them. If that TPU is 4.0 already then expect Google to buy an ungodly amount of these EPYC servers to match them as Intel have absolutely nothing to match here, not until 2021, next year Ice Lake is only rumored to ship with 26 cores tops.
