Ryzen 7 7800X3D processor

In total for today's Ryzen 7 7800X3D launch-day testing I ran more than 240 benchmarks across all of these different CPUs on the near-final Ubuntu 23.04 with Linux 6.2. You can see all the individual benchmarks and their associated power metrics and performance-per-Watt results via this result file.

Geometric Mean Of All Test Results benchmark with settings of Result Composite, AMD Ryzen 7 7800X3D Linux Benchmarks. Ryzen 9 7950X was the fastest.

When taking the geometric mean of all 240+ benchmarks, the Ryzen 7 7800X3D came out overall similar to the Ryzen 7 7700X. The Ryzen 7 7700X had the advantage of the 5.4GHz boost clock compared to 5.0GHz with the 7800X3D. However, in many technical computing workloads like OpenFOAM 10 CFD, the Ryzen 7 7800X3D was performing particularly well and even competing with the Ryzen 9 7900X/7950X processors. As shown over the past number of weeks, there are a variety of technical workloads on Linux where these AMD Zen 4 3D V-Cache processors can perform very well.

While having a 120 Watt rated default TDP, in my tests under Linux the Ryzen 7 7800X3D never topped 92 Watts in these benchmarks. That's with the latest BIOS and relying on the usual PowerCAP/RAPL sysfs interfaces. The Ryzen 7 7800X3D power consumption was much lower than the similar-performing Ryzen 7 7700X and also much lower than the other X3D parts. This further opens up the Ryzen 7 7800X3D for serving as an interesting ~$450 processor system for developers where dealing with workflows able to make use of the 3D V-Cache and desiring leading power efficiency. With the increasing number of AMD AM5 server motherboards/barebones coming about, the Ryzen 7 7800X3D with its robust power efficiency could also serve as a nice development server / continuous integration (CI) server or other small office / home office use-cases.

It's great seeing AMD continue to innovate with their AMD Ryzen 7000 series line-up and at $450 USD this is an interesting processor that can not only deliver great Linux gaming performance -- especially with not having to worry about any cache/frequency scheduler behavior -- but also a variety of other Linux uses. Thanks to AMD providing the Ryzen 7 7800X3D and other tested Ryzen processors for today's launch-day Linux performance coverage.
