AMD already works on the Navi 31 GPU, what will the Radeon RX 7900 XT look like?

We are seeing a lot of rumors lately about AMD RDNA 3 GPUs, so as we always say, they are rumors and have to be treated as such. That being said, the latest of them claim that the Big Navi GPU for the RDNA 3 generation, Navi 31, was going to feature 240 Compute Units or 120 CU per die for a total of 15,360 cores; However, it has now become known that the era of Compute Units is over for AMD and they are now treating them as WGP or Workgroup Processors for your next-gen GPUs.

What will the Radeon RX 7900 XT “Big Navi 31” look like?

Compute Units have been the building block of the AMD GPU family for nearly a decade, but with GPU MCD (Multi Chiplet Die) Next generation the amount of CU will increase dramatically. As such, a drastic change is also required and AMD could have decided to use WGP as the main term for its computing blocks. As we told you yesterday, each Navi 31 GPU matrix will have 30 WGP and 256 Stream Processors for each of them, giving us 7,680 cores per die or 15,360 cores in total.

There is also more interesting information that ensures that the flagship of the AMD RDNA 3 generation “Big Navi 31” could present a total of 60 WGP, which is equivalent to 120 compute units. There is also speculation regarding a CU design very different for chiplet-based GPUs and standard monolithic offerings like Navi 33. We would also find significant improvements in the shading motor.

Graphics memory design becomes more interesting as the Infinity Cache solution is integrated into AMD’s RDNA 3 GPUs. Navi 31 “Radeon RX” GPUs are expected to feature up to 512 MB of Infinity Cache, almost quadrupling the number of Navi 21 but retaining the 256-bit bus interface. The next graphs are expected to keep the memory matrices GDDR6 but with faster and more optimized power and frequency specs.

On the other hand, there have been several rumors that the upcoming RDNA 3 GPUs will outperform everything NVIDIA has to offer in terms of raster performance. It looks like AMD will take the lead this time by offering the first MCM-powered GPUs in its Radeon RX line of graphics cards, but at the same time NVIDIA is expected to make a rapid transition to its own MCM graphics line that will deliver a performance boost of more than three times compared to Ampere GPUs.

This is the expected return:

Navi 31 GPU performance

AMD’s new line of Radeon RX graphics cards with RDNA 3 architecture are expected to deliver up to three times the performance improvement over existing GPUs. It would mark a big step forward in the evolution of graphics and now that AMD is already on board with next-generation technologies like FSR and Ray Tracing, fierce competition is expected in the next generation of red and green equipment.
