AMD RDNA Three Leak Reveals How Highly effective RX 7000 Playing cards Will Be

AMD released its RX 6000 graphics cards a few months ago, but next generation cards based on the new RDNA 3 architecture are of course in the works. Leaker KittyYuko (via Wccftech) who had a successful streak of Ampere and Big Navi leaks shared some information about the upcoming Navi 33 GPU.

The cryptic optimization says that Navi 33 equals Navi 21, plus a next-generation IP core. This suggests an RDNA 3 core with specifications that match the current Navi 21 GPU.

Navi 33 (?) = Navi 21 + next generation IP core

The variants of Navi 21 are in the RX 6900 XT, 6800 XT and 6800. The top-end chip in the 6900 XT has 80 processing units, 80 RT cores and 5,120 shaders and, according to KittyYuko, the next generation Navi 33, the GPU has the same specifications. However, a patent from last year shows that AMD may be using a Ryzen processor-inspired chiplet design that places two GPU cores next to each other for a total of 160 compute units and 10,240 shaders.

In terms of overall performance, AMD saw approximately 50% improvement from gene to gene from GCN to RDNA and from RDNA to RDNA 2. Therefore, it would make sense to see twice as many computing units, RT cores and shaders in AMD's next units. gen cards.

However, the improvements could be much greater. Rumor has it that next-generation RX graphics cards are made on TSMC's 5nm process node and could offer a 2.5X increase over the current generation design. AMD has not yet unveiled RDNA 3, but AMD executive vice president Rick Bergman and Dr. Lisa Su, CEO, both confirmed that the company is working hard on it. Bergman highlighted the per watt performance improvement that RDNA 3 will bring and said it was "a big focus" for AMD.

We originally expected RDNA 3 graphics cards in late 2021 or early 2022. However, Twitter user @ Kepler_L2 suggests the cards won't be available until later in 2022. This could take even longer depending on the 5 nm supply from AMD. Semiconductor shortages are still gripping the world, and executives at companies like Intel suggest it will take several years for supply chains to fully recover.
