AMD Ryzen 9 7950X gets first preview, nearly 2x faster than previous generation

Sisoftware has unveiled the first preview of the yet-to-be- released AMD Ryzen 9 7950X processor based on the Zen4 microarchitecture . This is not an official review, but a collection of all publicly available data. The AMD Ryzen 7000 ships with the new AMD AM5 platform and added AVX-512 ISA support.

The AMD Ryzen 9 7950X features 16 cores/32 threads based on the Zen4 architecture. This processor has a base clock speed of 4.9 GHz , which can be boosted up to an insane 5.7 GHz . And that’s not all, the “F-max” frequency of this chip can reach 5.85 GHz . The Ryzen 9 7950X is rated at 170W TDP . For extra overclocking performance under heavy workloads, PPT ( Package Power Tracking ) can go up to 230W.

Sisoftware then mentions that if the AVX512 ISA is sufficiently well optimized, performance gains of over 100% can be seen in various programs.


In legacy integer testing, the Ryzen 9 7950X outperforms the latest generation 5950X by a whopping 42%. Legacy floating point increments are 31% over the 5950X and 37% over the 12900K .

When using the AVX-512 ISA, performance is greatly improved: the 7950X is 60% faster than the Zen3 king across the board.

Moving on to the image processing benchmark, the AVX512 does wonders with the 7950X, with the AMD Zen4 outperforming it by over 2x on average . The 7950X completely destroys the 12900K Alder Lake . Raptor Lake will need something big to catch up with those numbers. AMD has set the bar relatively high for the blue team this time around.

With AVX512 vectorized code for heavy computing, there is currently no better processor. Intel will have to bring the AVX512 back fairly quickly if it wants to stay competitive.


Efficiency and prices

Sisoftware did a comparison of performance and price, and the results show that the Ryzen 9 7950X is an absolute value for money. This processor gives you 2x the performance of the 5950X for the same price ( 39 points for $1 vs. 19 points for $1).

The efficiency is higher than that of the previous generation, but the increase is not as sharp. Compared to Intel , AMD always leads in terms of efficiency. For every watt used, the 7950X gives you extra performance.

With the Ryzen 7000 series debuting on September 27th , prices seem relatively low for the kind of performance you’re getting. However, the main hurdle for AMD is the price of AM5 combined with expensive DDR5 RAM . All things considered, this is an early investment as the AM5 will be supported for many years to come. We’ll keep you updated as new benchmarks become available.
