AMD’s RX 7900 XT reportedly “at a minimum 40% better than an RX 6900 XT”
AMD’s RX 7900 XT reportedly “at a minimum 40% better than an RX 6900 XT”
According to Moore’s Law is Dead, AMD is internally confident that their RDNA 3 architecture will provide them with a graphics card that’s 60-80% more powerful than their Radeon RX 6900 XT, with the YouTuber predicting that AMD’s RX 7900 XT will “at a minimum be 40% better than the RX 6900 XT”.Â
RDNA 3 graphics cards reportedly feature models that feature an I/O die, and at least 1 compute die, making AMD’s next-generation graphics architecture a chiplet-based design. AMD’s chiplet approach is said to have larger performance penalties than AMD’s multi-chip approach with Ryzen, though the benefits of multi-chip GPU design appear to mitigate those downsides.Â
AMD has already confirmed publically that they target large performance/watt gains with their RDNA 3 architecture, hoping to achieve a similar uplift as their RDNA-to-RDNA 2 shift. This will give RDNA 3 a 50%+ gain in efficiency over RDNA 2, which is great news for all gamers. Lower power draw allows AMD to fit more performance into their graphics cards without facing power or thermal limits, which is great news for desktop and mobile GPU users alike. Â

Moore’s Law is Dead has also claimed that AMD’s next-generation RDNA 3 graphics cards will offer gamers a significant increase in Ray Tracing and Geometry performance per Dual-CU, a factor which will help to enable stronger performance for Radeon graphics cards in titles that rely on ray tracing.Â
The Per Dual-CU claim is worth noting here, as this should allow AMD to increase their GPU’s ray tracing performance without relying on higher CU counts to increase their RT throughput. If AMD also launches GPUs with higher CU counts with RDNA 3, gamers can expect AMD’s ray tracing performance to explode with their next-generation offerings.Â
With RDNA 3, AMD reportedly believes that they “can truly win” against Nvidia, a bold claim. AMD’s Radeon graphics architectures have seen staggering levels of improvement in recent years, and if AMD can continue this rate of improvement, there is no reason why AMD can’t achieve their bold performance targets,Â
AMD has already publically claimed that their RDNA 3 based graphics cards would use an “Advanced Node”, suggesting that RDNA 3 will be a post-7nm product. Whether or not RDNA 3 will be based on TSMC’s 5nm lithography node remains to be seen, though such a move is probable.Â
Whether or not these rumours prove to be true remains unseen. That said, we know that AMD is not sitting on their hands when it comes to Radeon’s architectural development. With the success of Ryzen, AMD now has the finances that they need to execute their R&D visions with RDNA, and that should help create a GPU market that’s more competitive than ever.Â
