Wonder if there is any new info in the paper. I hear they're well on the way to 2nd gen version.

a single processor baeating  an entire supercomputer (  the 82 fastest in the world ) is definetly good

These wafer scale devices are designed to be really good at a type of workload. The supercomputer they compared with might be differently optimised. Traditionally the Top500 list ranks based on fp64 performance, something I doubt the wafer scale device is much good at because it was designed to be good at AI stuff.

I know. it’s one specific type of workload that was measured 

the supercomputer that was beaten is also „ weak „ against the newest supercomputer from Fujitsu 

 

but that makes it still an impressive processor. I mean an entire hall of serverracks was beaten by a much smaller „ box „

when i first read the headlines that the company wanted to make this big boy processor I just thought they were mad. How would they want to cool this thing? How can you solder such a massive thing on a substrate? And many more challenges 

 

And they just did it
