AMD RDNA 3 & RDNA 4 GPU Rumors For Next-Gen Radeon RX Series Graphics Cards: Higher Prices, Higher Performance, 2H 2022 LaunchMLID 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 targeting greater than 50% performance increase over the Radeon RX 6900 XT graphics card with its RDNA 3 architecture.
He states that he is confident that AMD will be able to achieve a performance improvement of 60% at a minimum but also states that theoretical top performance and real-world performance aren't the same things. This is MLID basically talking about that 2.5x improvement figure from earlier and that it could be based on a certain simulation or workload. The average performance improvement may change in the final silicon though several leakers are still confident about RDNA 3 hitting that 2-2.5x performance increase over RDNA 2.
It is also mentioned that like RDNA 2, the top RDNA 3 SKU has changed a lot over the last few years. This means that the product has seen several variations but the development and mass production of V-Cache chiplet stacking technology has improved the confidence of the team building the next-gen GPU in regards to its performance. Another interesting thing listed in the rumor is that RDNA 3 is expected to bring a big efficiency & ray-tracing performance increase while also simultaneously upping the power demand on the high-end models.
