AMD introduces the Ryzen 7000 processors
AMD presents the new Ryzen 7000 processors on the new Zen 4 architecture. The manufacturer promises up to 35 percent more performance in games and up to 45 percent in other applications.
Thanks to the Zen 4 architecture, the Ryzen 7000 processors are said to have 13 percent faster instructions per cycle (IPC). New interface standards such as DDR5 and PCI Express Gen 5 should also speed up systems. The number of cores, however, remains the same. The CPUs are manufactured in the 5-nm process at TSMC. Here is an overview of the line-up with the specifications:
| CPU | Kerne / Threads | Basis- / Boost-Takt | TDP | PPT | Cache L2 | Cache L3 | Max. Speicher-Geschwindigkeit |
|---|---|---|---|---|---|---|---|
| Ryzen 9 7950X | 16 / 32 | 4.7 / 5.7 GHz | 170 Watt | 230 Watt | 16+1 MB | 64 MB | DDR5-5200 (2x16) |
| Ryzen 9 7900X | 12 / 24 | 4.7 / 5.6 GHz | 170 Watt | 230 Watt | 12+1 MB | 64 MB | DDR5-5200 (2x16) |
| Ryzen 7 7700X | 8/ 16 | 4.5 / 5.4 GHz | 105 Watt | 142 Watt | 8+1 MB | 32 MB | DDR5-5200 (2x16) |
| Ryzen 5 7600X | 6 / 12 | 4. 7 / 5.3 GHz | 105 Watt | 142 Watt | 6+1 MB | 32 MB | DDR5-5200 (2x16) |
The processors will be available from 27 September 2022 and AMD is quoting the same introductory price as for the previous generation. So the processors should probably cost between 300 to just over 800 francs (299 to 699 US dollars).
This is what AMD promises
AMD claims an increased IPC of around 13 per cent and up to 29 per cent higher single-thread performance at the presentation. This is mainly due to higher clock speeds of up to 5.7 GHz on the Ryzen 9 7950X - that's 800 MHz more than its predecessor.
In gaming, the performance of the flagship is said to be between six and 35 percent better. The entry-level Ryzen 5 7600X is said to beat Intel's flagship Core i9-12900K by an average of five per cent in 1080p resolution games.
AMD is also focusing on performance per watt at the presentation. For example, the 7950X is said to have a 47 per cent better performance per watt in the V-Ray benchmark compared to the 12900K.
As always, the manufacturer's specifications should be taken with a grain of salt. Only the independent reviews will show what the processors actually perform.
Socket AM5
AMD introduces the brand new socket AM5 with Ryzen 7000. AMD is switching from the Pin Grid Array (PGA) to the Land Grid Array (LGA). The 1718 pins are therefore no longer on the CPU but on the mainboard, as is also the case with Intel. With the change to the new socket, the mainboards are compatible with DDR5 and PCIe 5.0. Pleasing: All previous cooling systems fit on the AM5 boards. AMD promises that future Ryzen generations will be compatible with AM5 by 2025 at the latest.
New chipsets
The chipsets of the motherboards are also new. There are four of them. X670E and X670 are in the high-end range and the B650 and B650E are in the mid-range. Motherboards with X670/E will be launched in September, the B650/E in October. The difference between B650 and B650E is that B650E offers support for PCIe Gen 5 for graphics cards and SSDs, while B650 non-E supports PCIe 5.0 SSDs and PCIe 4 GPUs.
Alternative to XMP
AMD is also introducing a new memory profiling technology called EXPO, which makes memory overclocking easier. It is a royalty-free technology that includes specific memory settings for the AMD architecture - similar to Intel's XMP, which can still be used. .
