A series of brand new rumors regarding the AMD RDNA 3 and RDNA 4 GPUs that will power next-gen Radeon RX graphics cards have been leaked by Moore's Law Is Dead. The insider talks mainly about the RDNA 3 GPUs but also give a slight update on RDNA 4 GPUs, both of which will feature MCM chip designs.

MLID starts straight off by talking about the performance estimates and we have had several of those for a while now. We have seen previous rumors claiming a performance increase of up to 2.5x for RDNA 3 over RDNA 2 and MLID states that AMD was always targetting greater than 50% performance increase over the Radeon RX 6900 XT graphics card with its RDNA 3 architecture.
