RDNA2 “Navi 20” GPUs and RDNA “Navi 10 Refresh” GPUs will be together the new product portfolio for AMDs graphics cards

AMD currently seems to prepare several Radeon RX graphics cards based on the GPUs with Navi 2X (RDNA 2) and Navi 10 Refresh (RDNA 1). In an exclusive article on his new technology portal “Hardware Leaks” Rogame has presented several Navi-GPUs, ranging from Radeon RX to Radeon Pro graphics cards. As AMD has already indicated several times, the upcoming Radeon RX graphics cards will be split into two different GPU architectures: the next generation RDNA2-based navigation line-up and RDNA refresh cards.

Even with Navi 2X, the main focus is of course on the large Navi 21 chip, which is also sometimes referred to as the “Big Navi” GPU. It is expected that Navi 21 will be used on AMD’s enthusiast models to compete against NVIDIA’s current flagship products such as the GeForce RTX 2080 Ti and GeForce RTX 2080 SUPER, while challenging NVIDIA’s new GeForce product line with the Ampere architecture. What has been leaked so far:

  • Up to 80 processing units/5120 GPU cores
  • A die size of about 505 mm²
  • 50% better performance per Watt

All this still needs to be confirmed, but specs like this give AMD a real chance to be competitive not only in performance, but maybe even in performance per watt. Apart from the gaming performance, one of the many unknown puzzles with Navi21 is of course the pricing and AMD’s plan to segment such a large GPU. According to the leak, AMD is planning at least four variants of the Navi21 GPU, with the information coming from the PCI-IDs of the GPUs that have been leaked

Navi 21 XTX (0x731F:D0)
Navi 21 XT (0x731F:D1)
Navi 21 XL (0x731F:D3)
Navi 21 XLE (0x731F:DF)

Each GPU SKU will replace the existing Radeon RX 5000 series cards, but in a completely different performance segment. For comparison, Navi 10 also has four GPU-SKUs that are available for consumers. The Navi 10 XTX chip represents the performance peak with the Radeon RX 5700 XT 10th Anniversary Edition, followed by the Navi 10 XT GPU installed in the Radeon RX 5700 XT, the Navi 10 XL GPU in the Radeon RX 5700 and finally the Navi 10 XLE GPU of the Radeon RX 5600 XT .

In addition to the gaming graphics cards, there are also two Radeon Pro variants, which will also be based on the design of the Navi 21 GPU. Similar to the Radeon RX gaming cards, the Radeon Pro series would replace the Radeon Pro W5700X, which is equipped with the graphics processor Navi 10 XT, while the Navi 21 Pro-XLE will replace the current Radeon W5700 Pro graphics card. The following are the SKUs for the Radeon Pro Series based on the RDNA 2-GPU architecture:

The Navi 21 SKU fun doesn’t end here, of course, because AMD also makes at least four variants for next-generation Apple products, including

In addition to the Navi 21 GPU, there are also several PCI IDs for the AMD Navi 22 and Navi 23 GPUs, which are smaller than the Navi 21 chip, but whose die area is still about as large as that of the Navi 10 GPU. In the following, the device IDs for these GPUs are listed:

Rogame also mentions the Navi 10 Refresh lineup, which continues to be based on the RDNA 1 architecture but has important optimizations with a refined process node to achieve better performance than the existing Radeon RX 5000 series graphics cards. According to the leak, the GPU of the Navi 10 XT+ will replace the GPU of the Navi 10 XT on the 5700 XT, Navi 10 XM+ will replace Navi 10 XM on the 5600M and finally Navi 10 XTE+ will replace Navi 10 XLE on the 5600 XT.

The point of this product line is to offer something to the mainstream segment as well, while the large navigation GPUs cover the higher end of the spectrum. According to Rogame, there are at least three Navi 10 Refresh SKUs in the works, which also include at least three Navi 10 Refresh SKUs:

As reports suggest that the Big Navi ‘Navi 21’ GPU will be the first RDNA-2 chip to be made available to the gaming market, it is likely that an update to Navi 10 could cover the mainstream segment until AMD can launch its RDNA-2 powered mainstream product line with the Navi 22 and Navi 23 GPUs. This is interesting in terms of price. Rogame lists the chip sizes as follows:

  • AMD Navi 21 (505 mm²)
    AMD Navi 22 (340 mm²)
    AMD Navi 23 (240 mm²)

AMD itself sees itself in a good position and if one follows the manufacturer’s instructions then the PR films can be summarised as follows:

  • Optimized 7-nm process node
    Enthusiastic Desktop Graphics Card Options
    Support for ray tracing at hardware level
    A mixture of GDDR6 and HBM2 graphics cards
    More energy-efficient than first-generation navigation GPUs
