Also I don’t see how it’s any different to Ampere and Ada where INT32 instruction throughout is half FP32. Is there any evidence that...

Also, when it can't dual issue from the same wavefront, why can't they make it so that it could fill the other ALU from another...

Since (for reasons unknown to mankind) I can't reply to 7900 reviews thread anymore I'll just do it here. I dunno why people are...

Now that we have a production game using UE5.1, I'd really like to start seeing benchmarks of performance comparison for Nanite and...

There’s a recent Mesa commit that puts it all together. Most useful dual issue instruction is probably fmac, which is a 2-operand...

The Anandtech article briefly mentions it. While we’re on the subject of AMD’s L3 Infinity Cache, it’s notable here that it’s actually...

VOPD - see the speculation thread, there's nothing more to say, frankly. Pixel shaders seem likely to be wave64. RDNA 2 seems to...

On the SIMDs, is there any idea here on how often it will dual issue ? I mean vaguely of course. I assume it's most of the time or it...

Too much data traffic. You do a lot of hierZ and stuff in there.

ROP is a screen-space construct these days, each of which owns sets of screen tiles that don’t necessarily map 1:1 to interleaved memory...

Why not put the ROPs on the MCDs as well? Dont' they usually benefit from being as close as possible to the cache and memory? Or maybe...

architecture "to exceed 3GHz" confirmed

Wonder what Ryan was talking about. GCN as scalar as it gets, has literally 0 instruction coissuing capabilities. If anything, Fermi...

No. They moved to software scoreboarding, and introduced a very limited form of VLIW2, supporting only a subset of opcodes. The ISA...

I'd wager it will be a miniscule number of games that require RT GPUs to run.
