AMD Navi 21 “Big Navi” GPU Stack Leaks Indicates Future Roadmap For Radeon RX Graphics Cards

AMD has been actively readying and testing multiple variants of the upcoming Radeon RX Graphics Cards which will be based on the new ‘Big’ Navi Architecture. However, the company has been rather quiet about the exact specifications. But a new leak is offering some details about the future roadmap for the Navi 21 (RDNA 2) and Navi 10 Refresh (RDNA 1) GPUs.

As AMD has previously implied, there will be three ‘Big’ Navi 2020 refresh for AMD Radeon RX Graphics Cards. The AMD Big Navi 21 Series was reportedly the most expensive, and reserved for a top-end graphics card with hardware-level ray-tracing. AMD’s upcoming “Big Navi” Navi 21 GPU will be applicable across Gaming, Pro, and Apple-exclusive segments indicate the latest leak.

AMD Navi 21 Based On RDNA 2 Architecture Gaming Radeon RX Graphics Cards GPU SKU Leak:

AMD has indicated that it is working not only on RDNA 2X but also on RDNA 3X architectures. Now serial tipster @_rogame has posted some interesting information on AMD’s “Big Navi” GPU as well as a Navi 10 Refresh for the low-end and mid-range gaming segment. This report ties in well with the PCIe device IDs that @_rogame posted last month. Simply put, there’s a lot of consistency, and eager AMD Radeon RX Graphics Card buyers can expect multiple variants to arrive before the end of the year.

As reported earlier, Navi 2x will feature three GPUs: the Navi 21 (505 m²), Navi 22 (340 mm²), and Navi 23 (240 mm²).  According to a new leak, AMD is planning at least four variants of the Navi 21 GPU which should power the premium Radeon RX Graphics Cards. The leaked PCI IDs of the GPUs indicates the same. Following are the SKUs as revealed by the tipster:

The AMD Big Navi 21 RDNA2 will be primarily segmented for three markets: Gaming, Pro, and Apple. In other words, each variant of the SKU will be part of a different performance segment. The commercial gaming variants include the XTX, XT, XL, and XE SKUs. These are quite similar to the current-generation AMD Radeon RX 5600 and 5700 series GPUs. As has been the norm, each GPU SKU or PCI ID will be replacing the existing cards in the Radeon RX 5000 series family.

The AMD Navi 10 Refresh also has four GPU SKUs that are available to consumers. The Navi 10 XTX chip is the top-end part which will power the Radeon RX 5700 XT 10th Anniversary Edition. Next up is the Navi 10 XT GPU that will power the Radeon RX 5700 XT, and Navi 10 XL which will power the Radeon RX 5700. Finally, the Navi 10 XLE will power the Radeon RX 5600 XT.

The XT and XL SKUs will also be offered as Pro variants. These will be intended for the workstation market. We have previously reported on the Radeon Pro W5700X and the Radeon Pro W5700, and the next generation should have products for the enterprise segment from the Big Navi RDNA2 family. Interestingly, AMD is reportedly making early-access XT and XL chips as well as their Pro variants exclusively for Apple. The iPhone maker would use the top-end premium variants in the upcoming iMac/iMac Pro Refresh and the next Mac Pro.

Strangely, the leaked GPU SKU or PCI ID list does not have any mention of mobile variants. Additionally, there’s no “G” for GXL models. If that’s not odd enough, the original list features Navi 10 Refresh but the Device IDs mentioned are identical to the Big Navi 21.
