A report is producing the rounds saying AMD will not start Zen 4 until finally This autumn 2022, with RDNA3 tipping up at the same time. It is not the initially time AMD would have synchronized a CPU and GPU start, but it indicates a extended-than-predicted hold off concerning Zen 3 and Zen 4.

This autumn 2022

A person point we have acquired in the latest times is that AMD will start Ryzen CPUs equipped with a significant, vertically mounted L3 cache later on this calendar year. It’s not apparent which CPUs the aspect will occur to — AMD showed off a 5900X 12-core thusly outfitted — but we expect to see these CPUs launch right before the stop of the year. It is not very clear how considerably down the products stack the attribute would stretch, but AMD has implied we could see a 15 efficiency uplift at the exact same frequency in comparison with a 5900X with a standard 32MB L3 cache per chiplet.

We know less about what RDNA3 could appear like. Texts from late May hinted that we may see a dual-chiplet architecture with 80 CUs for every chiplet, or 10,240 cores in full assuming 64 GPU cores for every CU.

-5nm(no subject TSMC or SEC)

-Advertisement102 in transition or GH202 in revolution?

-RDNA3, GFX11, how does AMD reach its perf intention? Double the SIMD in CU?

-How about Intel?

At a guess, SEC is Samsung Electronics Company, not the Securities and Trade Fee. Some factors of this make sense. RDNA3 staying on 5nm alongside with Zen 4 by the conclusion of 2022? Very easily plausible. But if this timeline is correct, and generally take experiences like this with a grain of salt, AMD won’t refresh RDNA2 for very a lengthy time.

AMD has not retained pace with Nvidia’s GPU start agenda for at the very least 5 years. RDNA and RDNA2 had been pitched as closing the hole, with RDNA debuting in July 2019 and RDNA2 launched November 2020. Holding RDNA3 till This autumn 2022 would be a roughly two-year hole in between RDNA2 and RDNA3. That is longer than we’ve observed beforehand the hole in between Vega 64 (August 2017) and Radeon VII (February 2019) was 18 months, not 24.

AMD has struggled to supply the GPU market place given that pandemic-relevant shortages started, probably because of to the number of chips it’s been setting up for Sony and Microsoft. The PlayStation 5 and Xbox Series X SoCs are not as big as GPUs like the Radeon 6800 XT, but they are not specifically little, either. The Xbox Sequence X is a 360.4mm sq chip, whilst the PS5 actions 308 mm sq. Which is roughly on par with the 6700 XT, which fields a 335mm sq chip.

This rumor isn’t necessarily correct, of system. Even if it is, AMD may possibly maybe have an RDNA2 refresh prepared with tweaks to clocks or the underlying microarchitecture of the GPU. It seems unlikely that AMD would participate in the exact V-Cache trick yet again. We do not even know if it would advantage from accomplishing so, viewing as the RDNA2 relatives has much additional cache offered by default than your common large-end Ryzen 5000 (32MB as opposed to 128MB).

The most important attribute RDNA3 could present currently — no matter of when it launches — is availability at MSRP.
