IPC of AMD Zen 4 is 24% higher than that of Zen 3

The 8-core 16-thread Raphael processor engineering sample frequency reached 5.2 GHz, which is 10% higher than the current Ryzen 7 5800X with the same number of cores. However, the latest news indicates that the frequency of the commercially available Ryzen 7000 series based on the Zen 4 architecture may be higher.

According to Moore’s Law is Dead, AMD Zen 4’s IPC is 24% higher than Zen 3, which means the IPC increase from Zen 3 to Zen 4 is higher than Zen 2 to Zen 3 (19%). In addition, the frequency is expected to increase by 8% to 14%. Although there are no specific numbers, referring to the existing data, single-threaded performance can be improved by 28% to 37%, and multi-threading will have a similar improvement.

The release time of AMD’s processors with the new architecture has also been updated, showing that all product lines will move to the Zen 4 architecture within a few months:
  • EPYC 7004 series (Genoa), A0 will be taped out in March this year, B0 is being tested, and will be released in the fourth quarter of 2022.
  • Ryzen 7000 series (Raphael), samples running, mass production coming soon, release in the second half of 2022.
  • Ryzen 7000 series (Dragon Range), samples are expected to come out within this year and be released in the first quarter of next year.
  • Ryzen 7000 series (Phoenix), testing progress later than Genoa, will be released in the first quarter of next year.
  • Threadripper 7000 series (Storm Peak), is planned to be released in the first half of next year.

The Threadripper 7000 series, codenamed Storm Peak, is rarely mentioned, first appearing in August last year. It is understood that the new generation of Threadripper processors has a maximum of 96 cores. Due to the late launch of the Threadripper 5000 series based on the Zen 3 architecture, AMD is likely to wait until the second quarter of 2023 to release the next-generation products.
