Just want to flag a potential unit issue: 900gbps vs 300GB/s?

Also worth noting - TPUv4 uses a 6-way 3D torus interconnect vs the 3-way "multi ToR" NVLINK topology; the total bisection bandwidth of the TPUv4 pod is over 1PB/s!

Can't wait to see what TPUv5 looks like. As you say, it's probably already chugging away with v6 on track to tape out in a year.

That said, I think NVidia has nailed bringing the ecosystem along, and I think making the whole setup look more like "one huge GPU" could simplify a lot of ML programming.

I am actually disappointed I haven't seen more of that style in CPU programming. Where's my 20,000 core 100TB RAM VM instance?
