According to well-reputed leaker @Broly_X1 on Twitter, AMD’s next-gen GPU and CPU offerings will launch roughly around the same time late next year. The next-gen Ryzen 6000 processors are going to feature TSMC’s 5nm EUV process along with the new Zen 4 core architecture (and possibly 3D V-Cache), and as such you can easily expect a performance boost of up to 25-30% compared to the Zen 3-based Ryzen 5000 lineup.
As per rumors, we will see two additional CPU lineups from AMD before Zen 4 launches in the last quarter of 2022. However, I’m skeptical, and a single Zen 3+ refresh based on TSMC’s 6nm process is more likely, although we may see a single or dual-product stack with the 3D V-Cache technology as already explained the other day.
As for the next-gen Radeon RX 7000 GPU lineup, we’re expecting a chiplet approach (at least at the higher-end). The source believes that RDNA 3 will be taped out later this year, meaning we should start seeing a fair number of leaks by early 2022. There are two main GPUs that have been discussed, namely Navi 31 and Navi 33.
Navi 33 will most likely be Navi 21 with the same 80 CUs (or 5,120 cores) but built atop the Navi 3X microarchitecture with enhanced ray-tracing capabilities and possible hardware units for upscaling. Navi 31, on the other hand, is rumored to feature a chiplet design with two Navi 33 dies, bringing the core count to over 10,000 stream processors or 160 Compute Units (80 WGPs). Three compute chiplets are highly unlikely because of multiple reasons and none of the patents so far indicate a separate I/O die either. You can expect Navi 33 to be 30-50% faster than Navi 21 (RX 6800 XT/6900XT) while Navi 31 should be close to twice as faster. It’s unclear whether the two dies will be used for multiple SKUs, but taking the price considerations of the latter into account, Navi 31 will most likely power just a single GPU. Like with Navi 21, Navi 33 can and will be used for multiple designs down the stack.
