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.
AMD has partially been caught with its pants down on its GPUs. They’re claiming that they’re more power efficient, but really only in the context of laptops, handhelds and other embedded devices. They are not talking about the power/performance ratio, in which case nVidia easily beats them on the desktop.
They simply need a new GPU architecture that can handle all of the newer rendering concept being utilized these days. Desktop GPUs only use more power because we are looking at very demanding games that are ran at maximum settings. Eventually, these rendering ideas will show up on other platforms. At which point, either they admit graphical inferiority or waste more energy running those features than the competition.
