11/19/2022 at 2:00 p.m. by Maximilian Hohm – AMD seems to have removed a comparison between the Radeon RX 7900XTX and Nvidia’s Geforce RTX 4090 from the official slides at the last second. However, this does not have to mean that your own graphics card would be less efficient, but rather suggests a faulty methodology, especially against the background of the real consumption of the RTX 4090. Read more about this below.
Nvidia’s new RTX 4000 graphics cards are also not cost-conscious, but compared to the sometimes very power-hungry Ampere graphics cards, both the Geforce RTX 4090 and the Geforce RTX 4080 are usually below their intended TDPs in gaming operation. AMD, on the other hand, had significantly higher efficiency and superior manufacturing technology with RDNA2. RDNA3 will also receive a die shrink and should increase efficiency again. At the latest on release on 13.12. the manufacturers will no longer be able to avoid a comprehensive comparison.

Against this background in particular, AMD’s latest step, which Computerbase has followed, is surprising. The manufacturer has apparently removed graphs with an efficiency comparison to Nvidia’s Geforce RTX 4090 from its materials for the presentation of the Radeon RX 7900XT and RX 7900XTX. These are hidden under the footnote “RX 841” and compare both graphics cards in four titles in terms of their efficiency. The crux of the matter, however, is the methodology.

Instead of paying attention to the real power consumption, which can differ greatly from the total board power (TBP), they wanted to use this as a basis for comparison. From a current perspective, that would not do justice to the RTX 4090, which also regularly consumed less than its TBP in our test. Probably also to prevent corresponding criticism from the community, AMD must have decided not to make this comparison.
According to previous information, AMD’s Radeon RX 7900XTX, the upcoming flagship, should be classified between the Geforce RTX 4090 and RTX 4080, at least in terms of rasterizing performance. In addition, it offers a wide 384-bit memory interface and 24 GiB of graphics memory and should therefore be a decent graphics card for enthusiasts.
