AMD's RDNA2 graphics architecture, which sees real-time ray-tracing among other DirectX 12 Ultimate features, could see the company double the amount of stream processors generation-over-generation, according to a specs leak by _rogame. The increase in stream processors would fall in line with AMD's effort to increase performance/Watt by 50%. It may appear like the resulting SKUs finally measure up to the likes of the RTX 2080 Ti, but AMD has GeForce "Ampere" in its competitive calculus, and should the recent specs reveal hold up, the new "Navi 21" could end up being a performance-segment competitor to GeForce graphics cards based on the "GA104" ("TU104" successor), rather than a flagship-killer.

The RDNA2-based "Navi 21" GPU allegedly features 80 RDNA2 compute units amounting to 5,120 stream processors. AMD might tap into a refined 7 nm-class silicon fabrication node by TSMC to build these chips, either N7P or N7+. The die-size could measure up to 505 mm², and AMD could aim for a 50% performance/Watt gain over the "Navi 10." AMD could carve out as many as 10 SKUs out of the "Navi 21," but only three are relevant to the gamers. The SKU with the PCI device ID "0x731F: D1" succeeds the RX 5700 XT. The one bearing "0x731F: D3" succeeds the RX 5700, with a variant name "Navi 21 XL." The "Navi 21 XE" variant has a PCI ID of "0x731F: DF," and succeeds the RX 5600 XT.
