Dr. Lisa Su took the floor at the AMD together we advance_PCs conference and showed the future of Ryzen processors. Fans of proper performance will obviously find their way again.
Zen 4 architecture and performance difference
The new Ryzen 7000 series are made with an emphasis on performance and efficiency. The Zen 4 architecture delivers according to AMD 14% increase in IPC and 29% increase in performance on a single core. In the first case, it is a few percentage points more than the manufacturer originally anticipated. AMD was not afraid of a number of comparisons with Intel, the top chip Ryzen 9 7950X is supposed to bring 57% more performance in raytracing rendering and at the same time it will be 47% more economical in terms of consumption.
The Zen 4 architecture uses a 5nm manufacturing process, which includes support for AVX-512 to improve machine learning. AMD predicts up to 1.3x improvement for nT FP32 and 2.5x for nT Int8. FinFET technology is used in production and the result is faster, smaller and more efficient transistors. All this in cooperation with TSMC.
According to AMD, the Zen 4 architecture can deliver the same performance with 62% less power consumption, and the processor generates 49% more power for the same power consumption.
The Zen 4 chip cores themselves are 47% smaller compared to the Golden Cove cores in Intel’s Alder Lake chips. Overall, they take up half as much space.
In the future, AMD intends to bring not only the improved Zen 4 architecture with 3D V-Cache, as was the case with Zen 3, but also Zen 4c. It is supposed to be more efficient and compact chips. The AM5 platform will be supported at least until 2025.
We will be seeing LGA 1718 and AM5 for a long time. AMD showed the first four types of chipsets for motherboards with this socket – X670E, X670, B650E and B650. The X series will hit the market in September, the B series in October.
Extreme variants will bring support in particular PCIe 5.0 also for the graphics card, the basic version has to make do with this interface only for memory. The good news is that AM5 socket and motherboards will be compatible with AM4 CPU coolers.
RAM was not forgotten either. These can be overclocked more easily thanks to AMD EXPO technology. Profiles created for memory overclocking will offer lower latency, higher performance and a better overview of the overclocking capabilities of RAM modules.
Chips and performance
AMD has started with the Ryzen 9 7950X, which will represent the top of the range. The maximum frequency of this 16-core model goes up to 5,7 Ghz. Performance in games is up to 35% higher compared to the previous generation, but it depends on the game. For productivity and creative activities, these values are even higher.
Synthetic performance per core destroys Alder Lake even in the case of the lowest model.
The complete range of chips will include four models for the time being, which corresponds to the launch of the previous generation. The Ryzen 9 7950X will complement the R9 7900X, R7 7700X and R5 7600X models. They will be available from September 27.
Prices did not move as much as originally expected. Ryzen 5 7600X starts at $299as well as the R5 5600X at the time of release. The Ryzen 7 7700X will cost $399, which is $50 less than the R7 5800X.
The popular R9 5900X chip replaces the Ryzen 9 7900X with an identical $549 price tag. Top model The Ryzen 9 5950X will then be a full $100 cheaper.
The number of cores remains unchanged and thus the frequency and TDP in particular increase. Let’s recall that the three most powerful Ryzens had a TDP of 105, now the Ryzens 9 reach a TDP of 170 W. The cache size also increased from 32 and 64 MB to 38, 40, 76 and 80 MB depending on the model.
Game performance will vary by game and chip. However, the basic Ryzen 5 7600X should be a decent upgrade for a number of titles, as the chart below shows.
