Radeon RX 7900 with 20 Gbps GDDR6 memory according to the latest rumors
Video card enthusiasts know that in the latter part of the year, NVIDIA and AMD will return to collide with a new generation of GPUs. In home AMD everything seems to go smoothly to gradually bring the models of the family Radeon RX 7000 on the market. The first solutions should debut at November based on rumors. The heart of the new proposals is architecture RDNA 3a project that aims at increase performance per watt by more than 50% compared to what has been achieved by the RDNA 2 architecture.
The adoption of the production process a 5 nanometersas well as the use of advanced packaging technologies and the chiplet approach popularized by the Ryzen family CPUs, will play a pivotal role alongside the new generation of Infinity Cache and other improvements.
While waiting for AMD to enter into the merits of all the news, the rumors about the technical specifications of the new RDNA 3 GPUs are becoming more and more complete (and we hope also truthful). In the past few hours the leaker Greymon55 he has declared that RX 7900 series models will feature 20 Gbps GDDR6 memory, a value higher than the 18 Gbps that has been rumored for months. Faster VRAM means higher bandwidth and potentially higher performance.
Based on rumors spread by RedGamingTechAMD’s top of the range for the next generation could be called Radeon RX 7975 XT. A GPU on board Navi 31 with 12288 stream processors and 24 GB of GDDR6 memory at 20 Gbps on 384-bit bus for a bandwidth – not counting the effect of the new generation of Infinity Cache – equal to 960 GB / s.
Navi 31 should end up on two other models, Radeon RX 7950 XT e RX 7900 XTobviously in a weakened configuration: in one case we speak of 11264 SP and 10240 in the other. The 7950 XT should keep 24 GB of GDDR6 memory at 20 Gbps on 384-bit buses such as the 7975 XT, while the RX 7900 XT may have 20 GB of GDDR6 memory at 20 Gbps on a 320-bit busfor a maximum bandwidth of 800 GB / s (again without counting the effect of Infinity Cache).
Even the family Radeon RX 7800 should have three models – RX 7800 XT, 7800 and 7700 XT – based on a GPU called Navi 32. The specifications leaked so far indicate for these models a quantity of stream processors respectively equal to 8192, 7168 e 6144. The 7800 XT should be paired with 16 GB of GDDR6 memory on a 256-bit bus, the RX 7800 with 16 or 12 GB of GDDR6 memory on a 192/256-bit bus, and finally, the RX 7700 XT should have 12 GB of GDDR6 memory on 192-bit bus.
To conclude, AMD would also have the cards in the pipeline RX 7600 XT, RX 7600 e RX 7500 XTbut these are probably models that we will only see in the course of 2023. All of these cards should be based on a GPU Navi 33: The 7600 XT should have 5120 stream processors and 8 GB of GDDR6 memory on 128-bit buses, the RX 7600 on 4096 stream processors and the same memory configuration as the XT and the 7500 XT should aim to offer 2560 stream processors and 6 GB of GDDR6 memory on 96-bit bus.
Since these are indiscretions it is always good to take them with the benefit of the doubt. In the rumor game it will be interesting to see how many of these “predictions” turn out to be spot on and how the cold numbers will turn into performance, especially compared to the strong NVIDIA competition.
