On the occasion of its Financial Analyst Day, AMD unveiled more information about its upcoming “Zen 4” CPU architecture. Expected later this year on Ryzen 7000 desktop processors, the latter would focus in particular on energy efficiency with its new 5 nm engraving.
It didn’t take long after Computex for AMD to be talked about again. The group organized its traditional Financial Analyst Day this week, the opportunity to say more about its projects, but also to give us concrete clues of what we can expect from the Zen 4 architecture. which will power Ryzen 7000 desktop processors later this year.
As pointed out AnandTech, this is the first time that AMD has revealed precise data concerning its new CPU architecture, particularly with regard to IPC (instructions per cycle). We thus learn that this new design will make it possible to develop between 8 and 10% more IPC compared to the Zen 3 architecture. single thread up to 15%.
Performance boosted by increasing energy efficiency
These performances, the firm would mainly succeed in obtaining them by raising the frequencies applied to these future Ryzen 7000 processors. A rise in frequency allowed by the progress of the Zen 4 architecture in terms of energy efficiency. The latter will leverage TSMC’s 5nm etching to deliver, according to AMD, up to 25% more performance-per-watt over Zen 3 architecture — at least on a desktop Ryzen 7000 processor with of 16 cores used for measurements.

All in all, AMD is talking about a 35% increase in overall performance for its next-generation processors. A figure that will deserve to be confirmed (or not) by independent tests, but which could indeed be achieved thanks to the better performance per thread promised for the Zen 4 design, but also thanks to the higher TDPs previously announced by AMD, underlines AnandTech.
On its roadmap, AMD also mentions the arrival of “V-Cache” stacking technology on its Zen 4 architecture. As on current Zen 3 chips, only a few references will be affected, but the firm ensures that this technology will be perpetuated in its CPU offer. We finally learn that the Zen 5 architecture, initially based on 4 nm engraving, will arrive on the market by 2024 without further details at this stage.
