With that said, let's see what sort of configurations we can expect with the Navi 3x "RDNA 3" GPU lineup.
The company's Senior Vice President of Engineering, Radeon Technologies Group, David Wang, said that the next-gen GPUs for Radeon RX 7000 series will offer over 50% performance per watt uplift vs the existing RDNA 2 GPUs.The AMD Navi 31 GPU, the flagship RDNA 3 chip, would power the next-gen enthusiast cards such as the Radeon RX 7900 XT graphics card.The Navi 31 GPU will also carry 6 MCD's which will feature 16 MB Infinity Cache per die and are also likely to carry the 64-bit (32-bit x 2) memory controllers that will provide the chip with a 384-bit bus interface.
While this equals 96 MB of Infinity Cache which is lower than the 128 MB featured on the current Navi 21 GPUs, there's also a 3D-Stacked solution in the works which was pointed out recently and that would double the Infinity Cache with 32 MB (16 MB 0-hi + 16 MB 1-hi) capacities for a total of 192 MB of cache.The AMD Navi 32 GPU codenamed "Wheat Nas" is also one of the two MCM GPUs featured in the RDNA 3 lineup.The Navi 33 GCD is expected to feature 2 Shader Engines and each Shader Engine has 2 Shader Arrays (2 per SE / 4 in total).
Just like the Navi 32 GPUs, the Navi 33 chips will be focused first on the mobile lineup with early graphics performance putting them ahead of the Intel Arc Alchemist lineup at less than half the cost & while pulling less power.The outlet also talks about two new features coming to AMD RDNA 3 Navi 3x GPUs for Radeon RX 7000 series graphics cards such as:.The AMD Radeon RX 7000 "RDNA 3" GPU lineup based on the Nav 3x GPUs is expected to launch later this year with reports pitting the flagship Navi 31 launch first followed by Navi 32 and Navi 33 GPUs
