During Financial Analyst Day, AMD shared a lot of information about its upcoming products. Let’s try to summarize all the announcements.
AMD introduces some more Zen 4 and Zen 5
Therefore, on the occasion of FAD, AMD introduced new roadmaps for its future products and introduced Zen 5.
The Zen 4 family will be eligible for 3 different iterations:
- Basic Zen 4 at 5nm
- Zen 4 with 3D V-Cache at 5nm
- Zen 4c (compact/dense) at 4nm.
The first processors of this family should appear at the end of the year along with the Ryzen 7000.
Zen 4 is described as the first high performance x86 processor in the 5m. This will result in a significant increase in performance per watt and frequency. Finally introduced IPC, which is 8-10% more than Zen 3 (thanks AVX 512!). In addition to faster frequencies, this promises single-core gains of over 15%.
So in Cinebench R23, the upcoming 7950X will have >25% performance per watt and >35% multithreading.
After Zen 4, the Zen 5 family will come, which will also be split into three different “architectures”: Zen 5 and Zen 5 3D V-Cache at 4nm and Zen 5c at 3nm.
The architecture this time will be significantly changed. This should lead to a fairly large increase in CPI and possibly a small increase in frequency (but stagnation or even decline cannot be ruled out).
Not forgetting server processors
Of course, the new architectures will be available in server versions with Zen 4 for Genoa, Genoa X with 96 cores, Siena with 64 cores and Zen 4c for Bergamo with 128 cores.
Genoa and Genoa X will feature 96 Zen 4 cores on a 5nm process with the latest technologies such as DDR5 and PCIe 5.0. The second will be entitled to more than 1 GB of L3 cache thanks to 3D V-Cache. Based on performance, we are over 75% faster with Java compared to Milano. The launch is scheduled for the fourth quarter of 2022.
Meanwhile, Bergamo will use 128 Zen 4c cores and get the same benefits over the Zen 4 architecture with one difference regarding the caching system. The release is scheduled for the first half of 2023 with a density performance 2 times higher than that of Milan.
In terms of processors, AMD will offer us some very good products in the future and now we have to see how Intel responds to that.
