AMD Says GPU Efficiency Doesn't Matter To Most PC Gamers, Will Do Better On Ray Tracing In Future Generations (wccftech.com)

AMD's Radeon boss has talked about the RDNA 3 GPU power efficiency, 12VHPWR on Radeon RX 7000 GPUs & ray tracing capabilities.

The interview is very detailed and we would like you to visit Club386 and read the full thing here but some interesting comments were made regarding a few aspects of the RDNA 3 "Radeon RX 7000" GPU family and what we can expect in the coming generation.

Back when AMD was in the process of launching its RDNA 3 GPU architecture, the company promised a monumental +54% increase in power efficiency vs. RDNA 2 GPUs through the use of chiplets and other changes. However, the launch saw little gains in the efficiency department, all the while NVIDIA took their efficiency to a whole new level with the Ada GPU architecture. Scott says that AMD believes in offering good performance per watt across their GPU lineup & that it matters more on the notebook front. So far, AMD has only introduced its non-chiplet Navi 33 to laptops.

Righto, thanks for the detailed reply.

The CEO might not be far wrong in that case, the average user probably doesn't run their GPU long enough to notice efficiency gains. And given their preferred market are the ones with money to burn, it makes sense they'd target improved performance over efficiency.

I'm inclined to agree as well, although I do think energy efficiency is environmentally important and the solution shouldn't be to throw more power at the hardware. For that reason I do appreciate some middleground between the two.

Realistically, my friends 7900XTX compared to my 3080 are within the same power consumption under load but he has 24GB of VRAM where I do not. To get that there with NVIDIA needs an extra 150 watts for the 4090 or 3090. Regardless of performance elsewhere, that's pretty sizeable, so it would be a shame to potentially lose that in place of something like a 30GB VRAM card pushing 450 watts from AMD.
