According to the latest report by computer based, AMD has reportedly removed a performance-per-watt graph comparing the cards to Nvidia’s RTX 4090 from their recent RX 7900 XTX and 7900 XT graphics card presentations. It’s the RX-841 of the RX 7900 XTX, but AMD didn’t announce it.
Specifically, AMD initially announced the RX 7900 XTX and 7900 XT’s wattage savings compared to Nvidia’s very power-hungry GeForce RTX 4090 based on their published peak power consumption numbers (TBP/TGP). I was supposed to present a performance slide per. However, the decision to exclude the results was clearly made at the last minute as this slide was not shown and AMD inadvertently left this footnote in their presentation.
We have no confirmation as to why AMD decided to remove this slide. There are several possible reasons for the omission. Nvidia’s 40-series cards consume huge amounts of energy, but the new architecture is more power efficient than their predecessors. Additionally, the cards consume much less energy during the game and often don’t consume TGP completely.
For example, in our review of the RTX 4080, we found the card to have very good performance per watt. Nvidia-powered he outperformed the RTX 3090 Ti, consuming far less power while gaming than the max 320W TGP would allow. In fact, according to our tests, the RTX 4080 Founders Edition consumes just 221W at 1080p. Additionally, the only workload that could make the most of the RTX 4080’s power budget was Furmark combined with GPU overclocking.
Nvidia also tried to highlight the efficiency of the 4080. own articles on the same subject, (opens in new tab) The RTX 4080 says it can reach a power draw of just 251W in average gaming conditions (albeit at 1440p resolution), calling out the fact that its GPU doesn’t pull full TGP while gaming. According to Nvidia’s article, this is an impressive feat given that Nvidia’s previous-gen RTX 3090 Ti draws significantly more power than the RTX 3080 at 398W under typical gaming workloads. is. This accounts for his 37% power reduction of the RTX 4080, not considering the 4080’s slightly faster gaming performance.
It’s logical to expect AMD’s upcoming RDNA 3 GPUs to be so power efficient that they can easily match or beat the RTX 4090. However, as with all presentations, AMD wants to make sure it has enough leads to highlight the benefits of its architecture. Conversely, AMD said that the RTX 4090 likely won’t pull out the full TGP during gaming, so comparing the two cards based solely on their total power rating might not be the best approach. You may have noticed something.
We probably don’t know why AMD dropped the comparison, but one thing is for sure, it’s missing in the deck.
