Today it’s time to talk about the red side, more precisely the AMD Radeon RX 7900XTits future high-end GPU, where it is stated that thanks to the architecture AMD RDNA3and design chipletmaybe more than twice as fast compared to its predecessor, the current high-end GPU AMD Radeon RX 6900XT.
This shouldn’t surprise us, and for now we expect the same from NVIDIA and its GeForce RTX 4090which would be at least 2x faster in 4K games with RayTracing compared to the GeForce RTX 3090. In this way, a real leap in performance is coming in the future generation of GPUs on both sides, which will harden the competition even more and force the next generation of GPUs to leave Intel try to keep this pace.
The known leaker greymon55 believes that the chip-based GPU will be twice as fast as the 6900 XTbut the retail variant may even be a bit faster or slower, because energy consumption is further optimized. Additionally, the GCD (Graphics Die) of the RX 7900 XT will have a surface area of 350mm^2, which makes it slightly smaller than the AD103, the die that would power the GeForce RTX 4080, and it must be remembered that NVIDIA will continue to use a monolithic designand RT Cores and Tensor Cores take up quite a bit of array space.
In the case of AMD, all this technology fate of the graphics chip in the form of MCD (Memory Complex Die) which surround the main silicon, whose size is reduced.
Possible specifications of the AMD Radeon RX 7900 XT
According to the leaks we have so far, this graphic would come to life through a multi-chip design (MCM) built with the manufacturing processes of 5nm and 6nm hoping to have access to a total of 12288 stream processors (vs 5120 SP on the RX 6900 XT) with 24 GB of memory GDDR6 @ 18 Gbps with a memory interface of 384 bit (16 GB @ 16 Gbps with 256 bits) to achieve a bandwidth of 864 GB/s (vs 512 GB/s), while its TDP could reach up to 600W (against 300W).
