AMD that with architecture RDNA 4 he doesn’t want to go high-end, that’s a known fact. The successors to the Radeon RX 7900 have been canceled and we can only expect the Navi 44 for the low-end, which will aim somewhere around the GeForce RTX 4060 Ti to the Radeon RX 7700 XT, and the Navi 48 in the mainstream, where the performance of today’s RTX 4080 and possibly the future RTX 5070 is expected .We shouldn’t get any higher, however, information is now leaking about what the upcoming high-end card with RDNA 4 (apparently Radeon RX 8900 XTX) was supposed to look like. These cards are referred to as Navi 4X or Navi 4C and there were supposed to be 9, 50% more, against the Navi 31 with 6 Shader Engine (SE) units.
But the question is how many CU units there would be. If the card kept the same configuration of 16 CU per SE, we would be talking about 144 CU, which is already quite a high number. However, for example, a Radeon RX 7700 XT has this ratio of 20 CU to one SE (3 SE and 60 CU), which would bring us to 180 CU with 9 SE, i.e. almost double the current state. There were even rumors on the internet (by @adroc_thurston) claiming that it was even well over 200 CU. We’ll probably never know how much it actually was, but we can probably be pretty sure it was at least 144, and even that would mean very high performance close to the level of today’s GeForce RTX 4090.
Let’s remind you that for the time being everything indicates that AMD will not introduce high-end cards, but this has not been officially confirmed.
