Hardware leakers have been running wild over the past few days with plenty of purported insight regarding AMD’s next flagship GPU, the RDNA 3-based Navi 31. According to a roundup shared by 3DCenter, Navi 31 will be built on one of TSMC’s 5 nanometer or 6 nanometer processes and leverage a multi-chip module (MCM) design comprising two graphics core dies and a single multi-cache die. What would presumably be the Radeon RX 7900 XT is also said to feature 15,360 cores, 256-bit GDDR6 memory, and a larger Infinity Cache (the Radeon RX 6900 XT features 128 MB of Infinity Cache). AMD’s Navi 31 GPU will supposedly offer 2.5x the performance of Navi 21 and release in the second half of 2022.

There have been several rumors stating that the upcoming RDNA 3 GPUs are going to outperform whatever NVIDIA has to offer in terms of rasterization performance. It looks like AMD will take the lead by offering the first MCM-powered GPUs under its Radeon RX graphics card lineup. But at the same time, NVIDIA is expected to quickly transition to its MCM GPU lineup which will offer over 3x performance boost over Ampere GPUs.
