AMD releases Zen 4 architecture Ryzen 7000 processor
Today, AMD officially released the Zen 4 architecture Ryzen 7000 series desktop processors. The new generation of processors is built with TSMC’s 5nm process. The new architecture is 13% higher than the existing product IPC, and supports DDR5 memory and PCI-E 5.0. The new AM5 platform will be a starting point for AMD’s new era. AMD promises to support the new platform until at least 2025.
The Ryzen 7000 series processors are very different in appearance from the previous Ryzen processors. The AM5 platform will use the LGA 1718 interface, and there are no pins on the back of the CPU. Now the CPU needs to be fixed with a fastener, but the radiator is compatible with the existing AM4, at least there is no need to replace the radiator.
Compared with the previous generation, the number of iGPUs of the Ryzen 7000 series processors has not changed significantly, the L2 cache capacity of each core is doubled from 512KB to 1MB, and support for the AVX-512 instruction set has been added. It is still 8 cores and one CCD, and each CCD has a 32MB shared L3 cache. The first four models will go on sale on September 27, including:
- Ryzen 9 7950X, 16 cores and 32 threads, the base clock is 4.5GHz, the boost clock reaches 5.7GHz, TDP 170W, the price is $699
-
Ryzen 9 7900X, 12 cores and 24 threads, the base clock is 4.7GHz, the boost clock reaches 5.6GHz, TDP 170W, the price is $549
-
Ryzen 7 7700X, 8 cores and 16 threads, the base clock is 4.5GHz, the boost clock reaches 5.4GHz, TDP 105W, the price is $399
-
Ryzen 5 7600X, 6 cores and 12 threads, the base clock is 4.7GHz, the boost clock reaches 5.3GHz, TDP 105W, the price is $299
The new Zen 4 architecture is 13% higher than the Zen 3 architecture IPC, while the Ryzen 7000 series desktop processors use the more advanced TSMC 5nm process. The boost clock can reach 5.7GHz, which is 800MHz higher than that of the Ryzen 5000 series. The combination of the two improves the single-threaded performance of the Ryzen 7000 processor by as much as 29%.
Compared with the Ryzen 5000 series processors, the Ryzen 7000 processor can bring a 29% increase in game performance, a 44% increase in computing performance for creators, and a 28% increase in energy consumption ratio.
Compared with the opponent’s Core i9-12900K, the game performance has increased by 11%, the computing performance has increased by 44%, and the energy consumption ratio has increased by 47%. This gap is not small. Of course, the top Core i9-13900K of the next-generation Core processor has 8 more E-Cores, and the frequency increase is not low. Coupled with the change of the cache, it is hard to say what will happen.
Compared with the Ryzen 9 7950X and the Ryzen 9 5950X, the most obvious improvement in game performance is “Shadow of Tomb Raider”, which has improved performance by as much as 35%.
This comparison is more interesting. The performance comparison between the Ryzen 9 7950X and the Ryzen 9 5950X under the same power situation. The performance of the new processor is improved by 74% at TDP 65W, 37% at 105W, and 35% at 170W. The new architecture and new process do have a great improvement in energy efficiency.
Among the improvements to the Zen 4 architecture, the new front end contributes the most to the IPC improvement, followed by the load/store system, followed by the branch predictor, execution engine, and doubled L2 cache.
AMD has launched EXPO memory overclocking technology, similar to Intel’s XMP 3.0. The user can directly enable the memory in the BIOS to make the memory work at the best frequency, the highest frequency can reach 6400MHz, with the low-latency DDR5 memory, the memory delay can be reduced to 63ns. There will be DDR5 memory that supports AMD EXPO technology from 15 different memory manufacturers.
In terms of motherboards, AMD has built four chipsets for the AM5 platform, including X670, X670E, B650, and B650E, of which X670 and X670E will come with the Ryzen 7000 processor. The B650 and B650E will be launched in October. The starting price of the motherboard is $125, but the matching PCI-E 5.0 SSD will have to wait until November. The newly launched Ryzen 7000 processor has an iGPU, but no specific details were announced at today’s conference.
