AMD updates CPU architecture product roadmap: Zen 5 architecture planned for 2024
AMD announced its own CPU product roadmap at its Financial Analyst Day event. In addition to the Zen 4 architecture that the upcoming Ryzen 7000 series processors will be equipped with, we can also see AMD intends to deploy the next-generation Zen 5 architecture in 2024.
From this picture, AMD’s Zen 4 architecture processor will contain three cores: Zen 4, Zen 4 V-Cache, and Zen 4c. At present, both Zen 4 and Zen 4 V-Cache have been ticked, indicating that these two cores are ready. The high-density version of Zen 4c is still in preparation, and this core will be used in the new generation of EPYC Bergamo processors. At present, there is not much news about Zen 4c. Zen 4 currently uses TSMC’s 5nm process, but there will be a 4nm version in the future.
Regarding the upcoming Zen 4 architecture, AMD has supplemented the news they announced at the Taipei Computer Show, and the IPC of the new architecture has increased between 8 and 10%. Thanks to the frequency increase brought by the new 5nm process, the single-threaded performance of the processor is improved by more than 15%. In addition, AMD also confirmed that the Zen 4 architecture supports AI and AVX-512 instruction sets.
AMD expects Zen 4 to increase performance per watt by more than 25% over Zen 3, while multi-threading will increase by more than 35%. These are based on the desktop version of the 16-core 32-thread processor. Of course, the performance improvement per watt does not mean that its power consumption is reduced. It is certain that the AM5 platform will have a higher socket power than the AM4 platform, and the maximum TDP of the processor has also increased to 170W, which is much higher than the current maximum 105W.
By 2024, AMD will plan to launch a new Zen 5 architecture, which, like Zen 4, will have three versions of Zen 5, Zen 5 V-Cache, and Zen 5c, and will have TSMC 4nm and 3nm versions. AMD refers to Zen 5 as a new microarchitecture, which means it’s not just an incremental improvement over Zen 4. The new Zen 5 will re-optimize the front-end pipeline, further increase the front-end width, and optimize the integrated AI and machine learning instructions. Compared with Zen 4, it will have better performance and energy consumption.
