SiSoftware already has various benchmarks with the AMD Ryzen 9 7950X and has compiled and compared them. In the end there is great praise for the new flagship, even if the increased power consumption is criticized. Intel Raptor Lake is still missing in the comparison.
In the tests that users created with the Sandra software suite from SiSoftware, the Ryzen 9 7950X (Zen4) competes against the predecessor Ryzen 9 5950X (Zen3), which also has 16 cores and 32 threads. There are also comparative values from Intel's Core i9-12900K (Alder Lake, 8+8 cores, 24 threads) and the Core i9-11900K (Rocket Lake, 8 cores, 16 threads).
Enormous benefits also thanks to AVX512
Due to the new architecture, the doubled L2 cache, the AVX512 support and last but not least the significantly higher clock rate including a greatly increased TDP, it is not surprising that the Ryzen 9 7950X can clearly beat its predecessor. In the first integer tests, the advantage of more than 40 percent is clearer than in floating point tests with around 30 percent. Intel's CPUs are already behind the Ryzen 9 5950X here and therefore have no chance.

The jump in performance from the Zen 4 is significantly smaller in the crypto/hashing benchmarks, where the lead over the Zen 3 is only 11 percent and 28 percent, respectively. SiSoftware points out that these tests depend primarily on RAM speed and Zen 4 benefits from the move to DDR5. Intel Alder Lake is actually significantly faster in some of these tests.

Sandra 20/21 Scientific Analysis (Image: SiSoftware)In benchmarks using financial analysis software, the Ryzen 9 7950X is 27 percent to 88 percent ahead of the 5950X. The benchmarks from the science area are even better for the Zen 4 with twice the performance compared to the Zen 3. In one test, however, Intel's Alder Lake architecture is also unassailable here, while it falls behind in the others.
In the average of the eight benchmarks for image processing, Zen 4 shines with an average of twice the performance compared to Zen 3. However, the Core i9-12900K can only take the top spot in one test. Here, too, the AVX512 support helps immensely, according to the report. Zen 4 is not always faster in the latency tests.

Compared to the Core i9-12900K, but with only half as many performance cores, the Zen 4 CPU is still 60 percent ahead.

A clear win by AMD without the challenger
In this comparison of the collected benchmark results, packaged as a “review”, the AMD Ryzen 7950X is convincing across the board. However, the actual opponent is still missing: Intel's Core i9-13900K from the Raptor Lake generation. This will offer twice as many efficiency cores, more cache and more clock. Intel had already promised performance increases of 15 percent in single-thread and 41 percent in multi-thread applications compared to Alder Lake. It remains to be seen to what extent this can be translated into the Sandra benchmark suite. Nevertheless, the duel with the Ryzen 9 7950X should get closer. However, Intel will have to increase power consumption again for this.
Real independent tests of the new Ryzen CPUs are expected in the coming days. The market launch is on September 27th.
Intel will probably only present Raptor Lake on the same day, while the first Z790 mainboards are to be unveiled at the same time. The first Core i 13000 models are expected to be available in October.
