Arm has been in supercomputers for a while. Astra at Sandia Labs was the first Arm peta-scale supercomputer, and the first on the Top500. It debuted in 2018. Fugaku is the fastest Arm supercomputer, taking the #1 spot on the Top500 in 2020. It is currently #4. All NVIDIA Grace-Hopper systems will be Arm. There is one in the top 10 already, Alps at the Swiss CSCS, at #6. There are four more in the top 100.

> Arm has been in supercomputers for a while. Apparently I am super wrong here. ARM has made serious inroads here as well. I think that ARM's willingness to allow their IP to be customized for their clients needs has really given them a lot of competitive advantages.

  That might be where Intel and AMD failed. With the hindsight watching ARM gobble up a number of sectors, Intel and AMD should have allowed their IP to be customized which may have slowed ARM's advance. Competition is good though. If this continues, AMD and Intel may have to merge. I wonder how RISCV is going to shake things up? Intel and AMD should build RISCV chips and chance ARM. That'll form a nice loop.

    > I wonder how RISCV is going to shake things up? Right now RISC-V is ultra slow in all implementations I've seen. Like 30x slower than a top of the line Apple Mx series CPU. Maybe there is a high performing RISC-V chip out there but I haven't yet run into one. RISC-V benchmarks: https://browser.geekbench.com/search?q=RISC-V https://browser.geekbench.com/search?q=RISC-V. Compare to an Apple M4 benchmark: https://browser.geekbench.com/v6/cpu/8224953 https://browser.geekbench.com/v6/cpu/8224953 That said, RISC-V is good for embedded applications where raw performance isn't a factor. I think no other markets are yet accessible to RISC-V chips until their performance massively improves.

Grace is NVIDIA's Arm CPU for servers, so the same will apply to Grace-Blackwell.

  Are there any good benchmarks on Grace as a CPU?
