Somehow, it feels strange to see the cache in big blocks, like that. I guess I'm so accustomed to seeing LLC being more distributed, but it's certainly better if a SM doesn't have to fetch something from the opposite corner of the die, for instance.

Here's the twitter link:

I'd love to know something about its interconnect topology. I wonder if there's any direct GPC-to-GPC communication path, or if all GPC communication has to go through L2.

Also, does anyone know what "3D FF" is referring to?

I found a spanish forum saying 3D FF are texture engines/ RT Cores. For what it's worth. They were looking at AD102 vs GH100

Thanks! I can believe it, but I'm just trying to make sense of the name. I guess the "FF" is short for Fixed Function (i.e. not programmable)?
