AMD introduced a new Zen4 architecture this year, which is a big change in terms of technology. The 5nm technology upgrade, a lot of kernel improvements, and the new AM5 platform, which supports DDR5 memory, PCIe 5.0 and other new technologies.
The Zen4 family already has a desktop version of Ryzen 7000 and a server version of EPYC 7000 series. At CES in the next few days, there will be a mobile version of Ryzen 7000, a Ryzen 7000G APU version and a 3D V-Cache version.
Throughout 2023,AMD's CPU line will be beefed up around the Zen4 to cover every market.
While the Zen4's architecture is not yet fully written down, the desktop Ryzen 7000 is a big improvement, but not as big as the Zen3's. The single-core and gaming performance is back to the level of the 12 Core, which is slightly less than the 13 Core.
And in the pricing also made the flagship Rydragon 9 7950X debut 5499 soon became 3999 yuan time, it is hard to avoid hitting the confidence of AMD high-end users.
A What else can you do with food? One is to expect AMD to continue polishing the 4nm Zen4. In addition to the Ryzen 7000 Mobile,The 3D V-Cache version of Ryzen 7000 will also be 4nm process, plus the advantage of super cache, to win back the lead on the game.
However, upgrading the Zen4 from 5nm to 4nm is unlikely to make a qualitative difference, which will require the next generation Zen5 architecture, which is still under development by AMD, but should be in the later stages.
For the Zen5, there aren't many details right now,AMD mentioned earlier that the Zen5 architecture would be built from scratch to continue improving performance and energy efficiency,There will also be Zen5, Zen5 V-Cache, and Zen5c variants.
Another important change for the Zen5 is the new technology upgrade, this time with 4nm and then 3nm. This looks similar to the 7nm and 6nm upgrades for the Zen3 and 5nm and 4nm for the Zen4, but it is different.
The previous two iterations of the upgrade process are compatible, while TSMC 4nm is a variant of 5nm, and 3nm is a new generation process that is incompatible with 4nm.
As for why AMD adopted such complicated and excessive Zen5 architecture, I'm afraid it has something to do with the schedule of TSMC's 3nm technology. One is delayed, the other is expensive, and only Apple can afford the limited initial production capacity. In 2023, almost all of the limited production capacity will be taken by Apple, and maybe only Intel can take part of the N3E process order.
NVIDIA, AMD, Qualcomm, Mediatek and others won't be able to use 3nm technology until at least 2024, and even then the chances of everyone using the 3nm Zen5 in 2024 aren't very high,Since the initial version will be a 4nm Zen5, the full blood version will be a 3nm Zen5 until 2025.
