AMD CDNA Discussion Thread

Thank you, kind sirs. I merely quoted the relevant bit for this thread.

That's CDNA, really.
Also funny NUMA slicing haha wonder what's they're gonna do with it

 

According to this leaker MI300 is 6nm



Wonder which changes it has if true

 

Not sure about the leaker's history, but in this tweet he/she is asking if it's possible for MI300 to be ported to 6nm. Literally: "is it possible for MI300 to be ported to 6nm?".

 

Sorry, then, My bad. I undestood differently.

 

His history is pretty good

 

Wroooong.
It does have N6 innit though.

 

3dCache all again? It could make sense, as it seems many complained about the difference in cache sizes with Nvidia's offerings...

 

MI300

 

Will MI300 consists of 4GCDs?




//So, 4GCDs on 6nm + HBMs. Will it even fit to OAM module package?

 

And other tiles.

Not designed to.
It's an APU.

 

SH5 socket.

It should fit SH5 socket.

 

Bingo.

 

My bad, I completely missed previous rumors

 

That's not a rumor, someone at DOE did a big oopsie.

 

Was this public oopsie? Can't remember it, not that I doubt it either

 

Fortunately no.
But it still let NV know everything they're ought to.
