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.
Yeah, it also matters the specific setups and cards. There’s still some issues with idle power on newer AMD cards in multi-monitor configs where they draw >50w doing nothing and some configs draw 100+w idling. It’s been an issue since the 7k cards released I believe. They’ve had a few updates which has helped for some people according to various reddit threads, but not everyone. I think the Nvidia ones by comparison only pull like 8w-20w idling.
This isn’t major for most users utilizing sleep most of the day, but it’s also add up over time.
