Roadmap of AMD CPU architectures as presented at Financial Analyst Day 2022 (Source: AMD) Zen 5: a major architectural change But it does mean that these processors will benefit from slightly better silicon properties. This isn’t some radical change, the N4 process is an improved derivative of the 5nm N5 process and there is some compatibility between the two. This is a surprise, because the Ryzen 7000 and Epyc 7004 (both Bergamo with Zen 4c and Genoa with standard Zen 4) are definitely 5nm according to previous officially communicated information.īut AMD has now revealed that the mobile version of Zen 4 codenamed “Phoenix Point”, which will launch in the Ryzen 7000 generation, will be manufactured on a 4nm process – presumably TSMC’s N4 technology. AMD says in the roadmap that Zen 4 will be manufactured on a 5nm process, but in addition to that also on 4nm technology. The second new information is about the production process.

This technology is therefore going to continue being part of AMD’s strategy. However, it is supposed to support all the instructions that the full-fledged Zen 4 can do (which includes the AVX-512).īut the roadmap now confirms that there will also be a Zen 4 with 3D V-Cache alongside the Zen 4c and the base Zen 4. This will be used in the Epyc 7004 Bergamo processors and seems to involve a smaller 元 cache and probably other modifications to reduce die area and increase power efficiency (at expense of lower peak performance). We’ve known for some time that Zen 4 will have a “compact” version of Zen 4c designed for cloud servers. The new content of the roadmap starts with the Zen 4 generation.

So it’s not clear yet that there will be a Zen 6 core (but there probably will be). For now, AMD has shown a roadmap ending in 2024, which includes Zen 4 and Zen 5. We’ll start with an overall roadmap of processor architectures – meaning the cores themselves, not specific processors. The company has revealed these plans for practically all market segments, which comes after a long time during which we didn’t see any roadmaps from it and could only rely on unconfirmed leaks. Now let’s take a look at the roadmaps for future processors. AMD processor roadmaps for 2022, 20 officially revealedįrom AMD’s Financial Day 2022 conference on Thursday, we’ve already covered here what the company said that was new about Zen 4 and Ryzen 7000 (especially the IPC reveal).
