AMD released its RX 6000 graphics card a few months ago, but the next generation of cards are based on the new rDNA 3 architecture, of course, in the works. Liker Kitiyuko (via Wccftech), who had a successful streak with Ampere and Big Navi Leak, shared some information about the upcoming Navi 33 GPU.
The cryptic tweak states that the Navi 33 is equivalent to the Navi 21, as well as a next-gen IP core. With the specs equivalent to the current Navi 21 GPU points to the rDNA 3 core.
Navi 33 (?) = Navi 21 + Next Gen IP Core

The Navi 21 variants are inside the RX 6900 XT, 6800 XT, and 6800. The top-end chip inside the 6900 XT has 80 compute units, 80 RT cores and 5,120 shades, and according to Kittyuko, the next-gen Navi 33 GPU will feature the same specs. However, a patent from last year suggests that AMD may use a chiplet design inspired by the Ryzen processor, which will place two GPU cores next to each other for a total of 160 compute units and 10,240 shades.
In general performance, AMD has seen a normal-on-gene improvement of about 50% from GCN to rDNA and rDNA to rDNA 2, so it would make sense to look at twice the computed units, RT cores and shades in AMD’s next . General Card.
The improvement can be immense, though. The Next-Gene RX graphics card is rumored to be built on TSMC’s 5 nm process node, and they can provide as much as 2.5x uplift on current-gen designs. AMD has not previously unveiled RDNA 3, but AMD Executive Vice President Rick Bergman and CEO Drs. Lisa Sue has both confirmed that the company is hard at work on it. Bergman said the performance-per-watt improvement would bring RDNA 3, noting that it is “a major focus” for AMD.
Originally, we expected an RDNA 3 graphics card in late 2021 or early 2022. However, Twitter users @ Kepler_2 It is suggested that the cards will not arrive until 2022 later. This may take longer depending on the 5nm supply available to AMD. The shortage of semiconductors is still gripping the world, and executives at companies such as Intel suggest it will take a few years for supply chains to fully recover.
