AMD has been working on RDNA 4 for some time, its next GPU architecture that will be used in the Radeon RX 8000 graphics cards, whose launch should take place between the end of this year and the first or second quarter of next year.
New data appearing in ROCm through GitHub confirms the existence of the Navi 44 and Navi 48 graphics cores, identified as GFX1200 and GFX1201. This gives strength to the rumors that Navi 41 had been cancelled. This graphics core was going to be the true top of the range within RDNA 4, since having been canceled there would no longer be, supposedly, a top of the range Radeon RX 8000 graphics card.
If this is confirmed there will be important changes with the Radeon RX 8000 compared to previous generations. Not only will AMD not release a top-of-the-line graphics card this generation, but high-end performance could be behind the top-of-the-line Radeon RX 7000 series.
The Navi 48 graphics core would be the most powerful, and will be used to create a graphics card whose performance would be approximately at the level of a Radeon RX 7900 XT. The rumors do not quite agree, some say that this new generation of AMD will use GDDR7 memory and others that it will not, that it will be limited to faster GDDR6.
I have also heard some speculation that says that AMD has made this decision because it wants to use RDNA 4 as a transition generation with which to start better using AI applied to games. Rumors speak of the use of the AI accelerator cores introduced with the Radeon RX 7000 to accelerate and improve the technologies incorporated by AMD FSR.
