  .. Nvidia GH200 Grace Hopper Superchip-powered supercomputer ...

  "What is the difference to alternative systems with the same amount of memory?
  - Compared to 8x Nvidia H100, GH200 costs 5x less, consumes 10x less energy and has roughly the same performance.
  - Compared to 8x Nvidia A100, GH200 costs 3x less, consumes 5x less energy and has a higher performance.
  - Compared to 4x AMD Mi300X, GH200 costs 2x less, consumes 4x less energy and has probably roughly the same performance.
  - Compared to 4x AMD Mi300A (which has only 512 GB memory, more is not possible because the maximum number of scale-up infinity links is 4), GH200 costs significantly less, consumes 3x less energy and has probably a higher performance.
  - Compared to 8x Nvidia RTX A6000 Ada which has significantly less memory (only 384GB), GH200 costs significantly less, consumes 3x less energy and has a higher performance.
  - Compared to 8x AMD Radeon PRO W7900 which has significantly less memory (only 384GB), GH200 costs the same, consumes 3x less energy and has a higher performance."

This is a weird comparison written to make things appear only good for GH200.

There are a bunch of tradeoffs that aren't considered and some of the comparisons don't make sense since GH200 is a cpu+gpu, so comparing against a gpu only, is weird.

There is no such thing as a 4x MI300 chassis, they are all 8x.

Considering the system only has a single H100, why would it be that performant?

Yeah this page is full of straight up lies?

“ Its performance in every regard is almost unreal (up to 284 times faster than x86).”

Like, there are at least 3 things wrong with that statement!
