Some time ago, popular leaker/YouTuber Moore's Law is Dead talked about AMD's upcoming RX 7000 series GPUs using the entry-level Navi 33 GPU and prophesized that it would bring a tangible performance uplift over its predecessor. Now, Tom has revealed some more information about AMD's next-generation RDNA3 graphics cards, and even mentions bits of information about RDNA4.
Most of the information sits in line with earlier RDNA3 leaks, which unanimously stated that the top-of-the-line Navi 31 GPU would use chiplets that will include 5 nm GDCs (Graphics Complex Dies) and 6 nm MCDs (Memory Complex Dies) stacked on top of each other, similar to the AMD Ryzen 7 5800X3D. A previous leak speculated that there would be two of the former and three of the latter, allowing AMD to pack nearly 15,000 cores into a single GPU.
The graphics card (presumably the Radeon RX 7900 XT) will feature a total of 512 MB infinity cache and up to 32 GB of VRAM on a 256-bit bus. Performance wise, it could offer double the Radeon RX 6900 XT's performance, at least in pure rasterizatrion, but its raytracing prowess remains largely unknown. As a cherry on top, it might draw a lot less power (450 W) than Nvidia's top-of-the-line offering, which has been rumoured to guzzle twice as much. AMD is expected to unveil it alongside a Navi 33 powered graphics card by the end of 2022.
The mid-range Navi 32 GPU will also feature an MCM design featuring two 5 nm GCD and 6 nm MCD tiles. However, it is slated to ship with lesser VRAM (16 GB) on a 192-bit bus and about 10,000 cores. It will draw about 300 Watts of power and offer a 50% performance uplift over the Radeon RX 6900 XT. However, an RDNA3 graphics card using the Navi 33 GPU will only hit shelves in H1, 2023, a while after the Navi 33 and Navi 31 cards have been out and about.
Tom rounds things off by stating that RDNA3' successor, RDNA4, could use GDDR7 memory. Previous leaks said that it will use a mix of 3 nm and 5 nm dies. However, recent trouble in TSMC's 3 nm manufacturing node could force AMD to switch things up a little. Then again, it is far too early to talk about a product that is unlikely to see the light of day for the coming months, if not years. In the meanwhile, one has to make do with refreshed RDNA2 graphics cards, which will reportedly be unveiled on May 10.
