The first RDNA 3 GPUs are rumored to become available in the autumn, though no precise release date has been announced. The first RX 7000 units are expected to be released between the end of October and the middle of November, according to Twitter user Greymon55.

DNA3 would increase over RDNA2 over 50% generational performance/Watt increases over RDNA. The next-generation GPUs will be manufactured using the TSMC N5 (5 nm EUV) silicon manufacturing process and will have a multi-chip module design similar to AMD processors. The logic dies containing the GPU's SIMD components will be produced on the most advanced node, while the I/O and display/media accelerators will be fabricated on a little older node. AMD's rivals won't let them have all the spotlight. No one really knows when Intel will deliver its highly anticipated Arc desktop graphics cards globally, but they're coming. Late summer is when AMD/NVIDIA move to faster GPU architecture. NVIDIA's GeForce RTX 40 series, codenamed "Ada Lovelace," would likely ship in September or October. 

Rumor: AMD would be planning First rDNA 3 Graphics Cards in october
