Specifications of Navi 32 and Navi 33, AMD’s upcoming RDNA 3 GPUs


AMD has already taken a step forward with the introduction of the Radeon RX 7900 XT and XTX, two high-end graphics cards based on RDNA Architecture 3 which use the Navi 31 GPU. This graphics core will also be present in the Radeon RX 7800 and Radeon RX 7800 XT, while the lower models will use two different GPUs, Navi 32 and Navi 33.

We already know the detailed specifications of the GPU Navi 31. We know that it has 96 CU in complete configurationequivalent 6,144 shaders because AMD didn’t end up doubling the number of shaders per compute unit, something that many rumors hinted at but ultimately didn’t materialize. The Navi 32 and Navi 33 GPU specs have been up in the air, but we finally have solid information thanks to a new leak.

The Navi 32 will be configured with 60 compute units, leaving us with a total 3,840 shaders. This graphics core will be the one AMD will use in the Radeon RX 7700 and Radeon RX 7700 XT, so we have a noticeable increase in shaders compared to the Radeon RX 6700 XT, as it has 2,560 shaders. We must not forget that, in addition, the Navi 32 will be a much more advanced, powerful and efficient GPU. Since the distribution of 4 texture units and one raytracing accelerator per CU is maintained, this chip will contain 240 TMU and 60 ray tracing units.

The RDNA 3 reaches the upper mid-range and mid-range with two different designs

As for the Navi 33, it is a mid-range GPU that will form the Radeon RX 7600 and Radeon RX 7600 XT. This chip will have 32 computing units and 2048 shaders, the same amount we found in the Radeon RX 6600 XT, although the difference in performance should be important due to the jump to the RDNA 3 architecture. This chip would feature 128 TMU and 32 ray tracing units.

It is important to be clear that although the number of shaders ultimately matters novelties introduced by the RDNA 3 architecture and the frequency is increasingthey will also play a major role and greatly affect the performance of the new Radeon RX 7000. So, the Radeon RX 7600 XT will be much more powerful than the Radeon RX 6600 XT, even though both will have the same number of shaders.

We must not forget that RDNA 3 introduces new accelerators for ray tracing, which has dual emission shaders, which means they can work with twice as many instructions. It’s also important to note that this new architecture will be AMD’s first for the mainstream consumer market accelerators dedicated to artificial intelligence, This opens the door to a new AI-powered version of FSR technology that is truly capable of competing with NVIDIA’s DLSS and Intel’s XeSS.

The Navi 32 will have the same MCD design we saw in the Navi 31, with a total of four 6nm chiplets hosting infinite cache, while the Navi 33 will have a monolithic core design with no external cache, meaning all the infinite cache will share encapsulation with the GPU.
