AMD Ryzen 9 7900X / Ryzen 9 7950X Benchmarks Show Impressive Zen 4 Linux Performance
For those running PHP scripts or doing server-side web development from your desktop, going from the Ryzen 9 5950X to 7950X yielded a 29% speed-up and the 7900X enjoyed a similarly sized big speed-up. But for as great as that is, Intel Alder Lake was still faster for the PHP performance and even Rocket Lake. PHP has historically performed very well on Intel CPUs given their server emphasis while at least with Zen 4 the gap has been narrowed a great deal. This is also a single-core PHP scripting benchmark and for those trying to build a LAMP server or so with a Zen 4 desktop CPU, there is more to consider for the overall performance and leveraging the higher core/thread count of the 7900 series.
Python scripting performance has also generally been the fastest with Intel CPUs, but these tested Zen 4 CPUs show that to be changing. Some of the Python benchmarks were now leading with the Ryzen 9 7900X/7950X while in other sub-tests it was a fierce competition.
Generationally though the Ryzen 9 7900 series is looking very great compared to prior Zen 3 and especially against Zen 2 if still running a Ryzen 3000 series processor or older.
As shown in the separate Zen 4 AVX-512 article, simdjson is one of the workloads able to make use of AVX-512 now with Zen 4 and is also why the Core i9 11900K is faster here than the Core i9 12900K. As such, the Ryzen 9 7900 series now able to easily outperform the Intel Alder Lake and Rocket Lake processors that previously had the upper-hand over the Zen 3 processors.
Thanks to AVX-512, the Ryzen 9 7900 series was performing exceptionally well for this workload.
