During a live event held on Thursday, May 26, AMD’s Technical Marketing Director Robert Hallock answered several questions about the Zen 4 processors.

Zen 4: Performance ? TDP ? RDNA2?

During Computex, AMD took the opportunity to reveal new information about their upcoming Zen 4 architecture, which will be used by the Ryzen 7000.

With a doubled L2 cache and a boost frequency exceeding 5 GHz (AMD showed gampeplay with a 16-core Zen 4 reaching 5.5 GHz in boost), the future Ryzen would offer more than 15% single-threaded performance compared to the 5950X (and not the 5800X3D which was mentioned as AMD’s fastest CPU).

That being said, there were still several questions, some of which were answered in a live Youtube interview with Robert Hallock on the HotHardware and PCWorld channels with an interview by TechPowerUp.

Ryzen 7000 are confirmed with 16 cores maximum, to have a higher core count, we will have to wait for the next generations. On the single-core performance, he reaffirms that the figures were “conservative” and that we will have to expect higher frequencies at launch, moreover the announced performance in multi-core (under R23 probably as for the single core) is about 40%!

Regarding the TDP, Robert Hallock wanted to come back on it, because of the confusion created by the TDP and PPT used by AMD. The TDP is indeed 170W with a PPT at 230W for the AM5 (against 105 and 142 for the AM4 platform).

Concerning the RDNA2 IGPU incorporated in the IO die of each Ryzen 7000, the characteristics will be identical between all the CPUs. This addition will not kill the APU range, which must offer decent graphics performance for video games, while the Ryzen 7000 have it for the sole purpose of being able to do without a GPU for display, video encoding, installing drivers …. A dozen other questions were answered during these interviews, we invite you to go and watch the video to see all the answers.
