AMD announced the highly anticipated AMD Ryzen 7000 processor and Zen 4 architecture at the “together we advance_PCs” conference yesterday on August 29, and announced AMD’s future development plans.
The Ryzen 7000 processors include the Ryzen 9 7950X and the Ryzen 9 7900X, Ryzen 7 700X and Ryzen 5 7600X, based on TSMC’s 5nm process and using the new Zen 4 architecture.
The Zen 4 architecture surpassed the preset target of a 10% increase in instructions per cycle (IPC), and the IPC increased by 13%. Compared with the previous generation Zen 3 architecture, the Zen 4 architecture improved single-threaded performance by 29% and multi-threaded performance by more than 35%.
Thanks to the cooperation with TSMC, the Zen 4 architecture also has a higher instruction speed per cycle and a better heat dissipation design, and the performance per watt is more than 25% higher than the previous generation.
The Zen 4 architecture also adds support for the AVX-512 instruction set. In March, Intel just announced that the subsequent 12th generation Core processors will disable this instruction set.
Intel has found that executing such instruction sets significantly increases CPU power consumption.
Su Zifeng said that the Geekbench scores of Ryzen 7000 all exceeded Intel’s flagship processor i9-12900K.
Su Zifeng also claimed that the Ryzen 7000 flagship model Ryzen 9 7950X is currently the most powerful gaming CPU in the world.
The Ryzen 9 7950X has 16 cores, 32 threads, a basic clock of 4.5GHz, and a maximum clock of 5.7GHz, which is 800MHz higher than the previous generation processor and 200MHz higher than Intel’s 12th-generation Core flagship processor i9-12900KS.
The actual performance of the game scene, AMD Ryzen 9 7950X “Tomb Raider” and other games provide a 35% performance improvement compared to the Core i9-12900K, and when performing v-ray scenes, the Ryzen 9 7950X is 62% faster than Intel’s flagship CPU i9-12900K, and each 47% higher watt performance.
The Ryzen 9 7900K has 12 cores, 24 threads, and a main clock of up to 5.6GHz. Its positioning is comparable to the AMD Ryzen 9 5900X, and it has the same price as the latter. It can be said that the increase in volume does not increase the price. As we already mentioned in a post before, The CPU giant decreased the prices.
The entry-level Ryzen 5 7600X has 6 cores and 12 threads, a base clock of 4.7GHz and a maximum clock of 5.3GHz. AMD claims that this entry-level chip still has a 5% performance improvement over Intel’s 12th-generation Core flagship.
Better Performance with Better Price?
In terms of price, the flagship AMD Ryzen 9 7950X is $699, the AMD Ryzen 9 7900X is $549, the Ryzen 7 7700X is $399, and the AMD Ryzen 5 7600X is $299.
AMD said that the Ryzen 7000 series processors will be available on September 27.
AMD also debuted a new GPU with RDNA 3 architecture. According to Su Zifeng, the GPU adopts a stack of small chips and adopts TSMC’s 5-nanometer process. Compared with the existing Radeon GPU, the performance per watt is improved by 50%.
A demonstration video of the Ryzen 9 7950X and the RNDA 3 architecture GPU executing the game was played on the spot, but the details of the GPU game performance were not announced.
In addition to publishing products, AMD also published a short-term roadmap.
AMD shows a more detailed Zen architecture blueprint, and in 2024 AMD will release a Zen 5 architecture processor with a 4/3nm process.
Su Zifeng said that AMD will release three new architectures, Zen4C, RDNA3 and XDNA in a few seasons.
