That said, I've been wondering if they could go with multiple smaller ones instead. Like one per layer maybe even?
What are your thoughts on that? You seem to be more qualified than me on that matter.
- thunderbird120 2mo agoLots of chiplet interconnects hurt your max performance pretty severely and drives up your complexity a lot. There's a reason they want to keep it monolithic. I already harped on Cerebras, but their approach of just copy/pasting a whole bunch of identical functional blocks, over-provisioning the chip by ~8%, and then just fusing off blocks with defects allows them to effectively have 100% yield on a wafer-sized monolithic chip. This is very desirable, and just another reason I like their approach better.
