Intel Core i5 13400 Linux Performance - Raptor Lake 10 Cores / 16 Threads For $239

Given the Core i5 13600K and Core i9 13900K Raptor Lake CPUs were both reviewed last year on Phoronix and working well under Linux, to no surprise the Core i5 13400 was also in good shape for Linux use on existing motherboards. The only caveat encountered is that while the RAPL CPU power monitoring with the K-series Raptor Lake processors was working since ~5.19, for the Core i5 13400 it was only working with Linux 6.1+, presumably due to just missing an additional ID. But in any case most Linux users aren't meticulously monitoring their CPU power consumption like I am during benchmarking...

So long story short, if you are running a modern Linux distribution you should be in good shape for running the Core i5 13400 and the other new Raptor Lake 65 Watt desktop processors.

For showing how the performance of the Core i5 13400 looks, in this article are benchmarks against an assortment of other recently tested AMD and Intel processors. The processors tested for this article included the:

- Core i5 12400
- Core i5 12600K
- Core i9 12900K
- Core i5 13400
- Core i5 13600K
- Core i9 13900K
- Ryzen 9 3900X
- Ryzen 9 3950X
- Ryzen 5 5600X
- Ryzen 7 5700G
- Ryzen 7 5800X
- Ryzen 7 5800X3D
- Ryzen 9 5900X
- Ryzen 9 5950X
- Ryzen 5 7600
- Ryzen 5 7600X
- Ryzen 7 7700
- Ryzen 7 7700X
- Ryzen 9 7900
- Ryzen 9 7900X
- Ryzen 9 7950X

All of the processors were tested on Ubuntu 22.10. The processors were tested with 2 x 16GB DDR5-6000 memory and then 2 x 16GB DDR4-3600 for the Zen 2/3 platforms, 2TB Samsung 980 PRO NVMe SSD, and AMD Radeon RX 6800 XT graphics. Basically a straight-forward continuation of the Linux testing from earlier this month following the Ryzen 5 7600 / Ryzen 7 7700 / Ryzen 9 7900 Linux review.
