AMD Ryzen 7 3700X + Ryzen 9 3900X Offer Incredible Linux Performance But With A Big Caveat

Here is a look at the geometric mean across all of the dozens of Linux CPU benchmarks carried out for this article. The Ryzen 7 3700X showed an 10% improvement or so over the Ryzen 7 3700X and that was about 5% faster than the Core i7 8700K. The Ryzen 9 3900X meanwhile performed very well and on the geometric basis was comparable to the Threadripper CPUs due to the mix of single and multi-threaded benchmarks. What's notable here though is that the Ryzen 9 3900X came out about 10% faster than the similarly priced Core i9 9900K.

Overall, the AMD Ryzen 7 3700X and Ryzen 9 3900X are very capable performers and ran superb. That is, when they could boot Linux. If it weren't for this major problem of newer Linux distributions not currently booting successfully with the new AMD hardware, it could have been an instant home-run for Linux enthusiasts looking for their next PC upgrade or replacement. It's still possible that this Linux systemd service issue might not be a big problem in the long-term assuming it's quickly rectified and some workaround exists for letting current Linux ISOs boot fine -- as opposed to having to wait until the next round of Linux distribution releases or jump through other steps like first installing the distribution using a separate CPU/motherboard in order to apply any patch/updates. But as of writing there is no easy solution and it's even more perplexing that Linux 5.2 can still run great with Ubuntu 18.04 LTS.

So as compelling as the performance is for the AMD 3700X/3900X, if you are a Linux user wanting to run a bleeding-edge distribution you may want to hold off on purchasing this new hardware until hearing more on Phoronix. But if you want to use the likes of Ubuntu 18.04 LTS, the Ryzen 7 3700X and Ryzen 9 3900X pose incredible competition to Intel's latest processors for both single and multi-threaded workloads.

I'll certainly be running follow-up tests over the days ahead as well as looking at the thermal/power consumption and other areas I didn't have time to address ahead of today's launch.
