Thanks to such internet clowns as JaysTwoCents who made such bullshit as water cooling in electronics a almost "desirable" norm.

I know this isn't anything new, the Voodoo 5 5500 was huge and that was 23 years ago, but ram, CPUs and GPUs have advanced to the point where you can get a laptop with a 16 core processor, 64gb, and Quadro GPU, the AMD AMD Ryzen 9 7900X has 12 cores and reasonably capable graphics in a relatively compact design, yet add-in graphics cards are huge, consume significant amounts of juice, generate a lot of heat and require 1 or 2 power connectors.
I think we should boycott any graphics card that is so physically large that it looks like someone is trying to compensate some other shortcoming.
We need new physics or completely new materials (photonics?) to tackle the issue.

Not a fan of large GPU's, ironically in general the bigger they are the better they are cooled, three fans help.

Doing that doesn't double performance but it does remove (or raise) a performance limit in certain compute bound scenarios. It's like having more ROPs - only makes a difference in certain scenarios but significant in those scenarios.
I'm curious where you saw the "4xFP" reference other than maybe packed instructions working on small data types (eg 2 FP16 instead of 1 FP32). I don't remember seeing any reference to 4x in our slides or ISA guide.
The only "4xFP" I can think of would be the combination of dual-issue and packed FP16, but even that would not be 4x since RDNA2 also supports packed FP16 IIRC.Last edited by bridgman; 26 August 2023, 01:41 PM.Test signature

I couldn't get 60Tflops to anything tho. I guess is 30Tflops + 15Tiops + Your Imagination
