Mystery AMD RX 5950 XT ‘Big Navi’ 7nm GPU Flagship With RDNA2 Packing 2X Performance Of RX 5700 XT Leaks Online

After the 7nm AMD Ryzen 4000 Series Mobility CPUs and APUs, the company is rumored to be introducing the powerful next-gen GPU based on the Big Navi or RDNA2 or Navi 2x Architecture. The flagship GPU of the upcoming AMD’s next-generation 7nm Navi 21 series is reportedly one of the largest in terms of die sizes, indicating several new aspects and features. Although the information is purely a rumor and uncorroborated at this stage, the AMD Big Navi based GPU, fabricated on the 7nm Fabrication Node, is expected to have significantly higher processing power than the current generation of AMD GPUs.

AMD’s next-generation 7nm Navi 21 GPU Has A Large 500+ mm Die Size With 2X Performance Of RX 5700 XT?

The current-generation AMD Vega Graphics has had a great run so far. Now the company will allegedly be ditching its Vega architecture in favor of RDNA 2-based Big Navi. Incidentally, the only confirmed RDNA 2 graphics that have been announced so far are the GPUs inside the upcoming Xbox Series X and the Sony PlayStation 5 game consoles.

Serial tipster AquariusZi who has been quite consistent and often accurate about leaks on AMD has posted (via KOMACHI_ENSAKA) the die sizes of AMD’s upcoming ‘Big Navi’ lineup. The upcoming 7nm AMD flagship GPU, which might be called the AMD RX 5950 XT, will allegedly feature a huge 505 die. Simple math indicates this roughly translates to at least 2x the performance of the current-generation RX 5700 XT GPU.

In addition to the flagship GPU that will undoubtedly be based on the Big Navi Architecture, the die sizes of the Navi 22 and Navi 23 have been leaked as well. According to the Tweet, the Navi 22 and Navi 23 will have 340 and 240 die sizes respectively. Incidentally, the measurements reportedly have an error of 5 on the up and down sides.

The AMD Navi 23 based GPU is likely going to be a successor for the current generation flagship, the RX 5700 XT. Moreover, considering the RX 5700XT is exactly 251, the die size for the Navi 21 does seem practical and possible. Based on the RDNA1 architecture, the current generation flagship contains 40 CUs (Compute Units).

AMD Navi 23 based GPU To Pack Double The Compute Units Or Compromise For Dedicated Ray Tracing Cores?

Based on the newer and much more powerful RDNA2 or Navi 2x Architecture, the upcoming AMD RX 5950XT could easily pack 80 Compute Units if the die sizes turn out to be accurate. This would translate into a total of 5120 Stream Processors. Even if efficiency improvements going from RDNA1 to RDNA2 are completely ignored, this would mean a 2X jump in performance compared to current generation AMD GPUs.

It is, however, important to note that there is still the matter of dedicated Ray Tracing Cores, which NVIDIA already accounts for in its own next generation of GPUs. If AMD does opt to deploy dedicated ray-tracing hardware in the Navi 2X family, then the Compute Units could drop significantly. Nonetheless, even if AMD adopts the same GPGPU approach to Ray Tracing dedicated cores, like NVIDIA’s deployment of Tensor cores on Turing, the flagship AMD GPU would still be a big leap over the current generation of RDNA1 based GPUs.

There’s little doubt that AMD is gearing up to launch its next generation of Navi 2x based GPUs with Ray Tracing. Several AMD cards have also recently passed RRA certification, which is a very strong indicator of an imminent launch of the new generation of Graphics Cards.

It is interesting to note that NVIDIA hasn’t offered many details about its own next-generation of Ampere-based GPUs. It is quite likely that NVIDIA is waiting for AMD to launch its own line of next-generation products to decide on the final retail pricing of its own products. Experts indicate AMD might name the new cards as Radeon RX 5950XT (the flagship), Radeon RX 5950, Radeon RX 5900 and the Radeon RX 5800.
