This morning AMD has presented the new Ryzen 7000 processors, a generation that uses the Zen 4 architecture and that, as we have seen in previous articles, is compatible with DDR5 memory and uses a new platform, known as AM5. However, this time AMD has focused on details at the architecture level and performance data, something totally understandable considering that a few weeks ago we already had the opportunity to learn more about the main motherboards designed for this new generation .
We have a great list of Graphics card. Check on Desktopman Graphics category to know more.
In the end, the forecasts that we had seen in the most recent leaks have been fulfilled, since AMD has announced a total of four new Ryzen 7000 processors , with which it covers the mid-range, the mid-high range, the high-end and the low-end. “top” or “enthusiastic”. These are all the models presented and confirmed for launch , ordered from least powerful to most powerful:
Ryzen 5 7600X: It has 6 cores and 12 threads running at 4.7 GHz-5.3 GHz, normal and turbo mode, adds 32 MB of L3 cache and 6 MB of L2 cache and has a TDP of 105 watts.
Ryzen 7 7700X: This processor has 8 cores and 16 threads running at 4.5 GHz-5.4 GHz, normal and turbo mode, it has 32 MB of L3 cache and 8 MB of L2 cache and its TDP is 105 watts.
Ryzen 9 7900X: It has 12 cores and 24 threads at 4.7 GHz-5.6 GHz, normal and turbo mode, it has 64 MB of L3 cache and 12 MB of L2 cache, and its TDP is 170 watts.
Ryzen 9 7950X: It has 16 cores and 32 threads at 4.5 GHz-5.7 GHz, normal and turbo mode, has 64 MB of L3 cache and 16 MB of L2 cache and has a TDP of 170 watts.
All these Ryzen 7000 processors come with an integrated Radeon GPU with two compute units (CUs), that is, with 128 shaders, enough for office automation, multimedia and old or undemanding games.
The Ryzen 7000 offer significant improvements in single-thread performance
During the presentation event AMD has confirmed that the Ryzen 7000 processors have improved the IPC by 13% compared to the Ryzen 5000, although thanks to the increase in the maximum working frequencies, which finally exceeds 5 GHz, the maximum improvement of Single-wire performance is up to 29% compared to the previous generation. We already talked about this topic a few weeks ago, when we told you everything we knew about the Ryzen 7000 and Zen 4 .
And how has AMD been able to improve the IPC so much compared to the previous generation? Thanks to five fundamental keys : doubling the amount of L2 cache per core, which goes from 512 KB to 1 MB, a new “front end” and improvements in load/storage, in the jump predictor and in the execution engine. It is also important to be clear that AMD has broken an important barrier with the Ryzen 7000 by widely exceeding 5 GHz, and that the increase in frequencies that it has achieved compared to the Ryzen 5000 has been so great that it is responsible for much of the increase in performance. single-wire performance of this new generation.
Ryzen 7000 processors will have an MCM design with between one and two CCD units (chiplets). Each chiplet consists of 8 Zen 4 cores, can handle 8 processes and 8 threads thanks to SMT technology, adds 32MB of L3 cache and 8MB of L2 cache, and is manufactured on the 5nm node. Said node uses FinFET technology and represents an important leap that has allowed the integration of smaller, faster and lower consumption transistors.
And speaking of consumption and efficiency, AMD has confirmed that the maximum TDP of the Ryzen 7000 will be 170 watts, but we must bear in mind that this new generation will be able to reach a PPT (package power tracing) of 230 watts in turbo mode , which means that the latter will be its maximum value. It is perfectly understandable, since AMD has fine-tuned the working frequencies and the turbo mode to the maximum so that this new generation of CPUs can develop its full power without problems. It is also important to note that these processors will support the AVX512 and VNNI instructions, which will significantly improve performance on INT8.
As in previous generations, the Ryzen 7000 has all the I/O elements outsourced , including the memory controllers, which are present in a chiplet manufactured on the 6nm node and interconnected with the CCD units. This interconnection between the CCD units and the I/O chiplet is done through the Infinity Fabric system.
AMD has also delved deeper into support for DDR5 memory, which is one of the key pillars on which this new generation of processors has been built, and took the opportunity to present AMD Extended Profiles for Overclocking , also known as EXPO. This technology is presented as an alternative to Intel XMP 3.0, and will allow you to overclock DDR5 memory with a simple click.
Thanks to this advance we can expect a performance improvement of up to 11% , low latency (up to 63 nanoseconds), very simple operation and a completely license-free and cost-free model. Major memory manufacturers including giants like Corsair, A-Data, GeIL, G.Skill, and Kingston have already confirmed that they will have several AMD EXPO compatible kits ready for launch with frequencies up to 6400 MHz.
A look at the performance and efficiency of the Ryzen 7000
During the presentation AMD showed numerous performance comparisons to demonstrate the generational leap that the Ryzen 7000 represents, and in general terms I can tell you that what I have seen fits perfectly with my expectations, since I was convinced that thanks to the increase in IPC and the great increase in AMD working frequencies was going to significantly improve the single-thread performance of the Ryzen 7000.
The Ryzen 9 7950X, which will be AMD’s most powerful chip within this new generation, is up to 62% faster than the Core i9-12900K in V-Ray Render , and if we compare it with the Ryzen 9 5950X we see that the performance improvement can reach up to 48%, also under such test.
In games, the difference in performance may vary depending on the specific game. For example, in Shadow of the Tomb Raider, the Ryzen 9 7590X outperforms the Intel Core i9-12900K by 14%, but in Borderlands 3, both achieve a tie. The Ryzen 5 7600X , which is undoubtedly the most attractive processor of the four for those who want to build a powerful and balanced gaming PC, easily beats the Core i9-12900K as it offers an average of 5% more performance in games.
