AMD Ryzen 7 7800X3D Review: Return Of The PC Gaming King
AMD Ryzen 7 7800X3D: 3D Rendering, Audio and Video Encoding
LAME XP Audio Encoding
For this test, we created 16-copies of our own 223MB WAV file (an 11 minute Grateful Dead jam) and converted it to the MP3 format using the multi-thread capable LAME XP tool. Processing times are recorded below, listed in minutes:seconds. Shorter times equate to better performance.
Intel's architectures perform best in this audio encoding test, but AMD's Zen 4 based chips are not too far behind. Surprisingly, the Ryzen 7 7800X3D ends up out-running the Ryzen 7 7700X here by a few seconds.
Blackmagic RAW Video Encoding Speed
The Blackmagic RAW Speed Test is a CPU and GPU benchmarking tool that tests full-resolution Blackmagic RAW video decode performance. The tool can be used to evaluate the performance at various resolutions and bitrates on the CPU or using OpenCL on a GPU. We're reporting two results here, both using 8K resolution, but at differing bitrates and compression levels for the CPU test alone.
The Ryzen 7 7800X3D returned to its familiar position, just behind the Ryzen 7 7700X. Note, however, that it does offer a big leap over the previous-gen Ryzen 7 5800X3D and it even beats the 5900X. The Zen 4 architecture simply offered better performance than Zen 3, so much so that it can overcome significant core count deficiencies in some cases.
Cinebench R23 Rendering Benchmark
Cinebench rendering performance test based on Cinema 4D from Maxon. Cinema 4D is a 3D rendering and animation tool suite used by animation houses and producers like Sony Animation and many others. It's very demanding of system processor resources and can utilize any number of threads, which make is an excellent gauge of computational throughput. This is a multi-threaded, multi-processor aware benchmark that renders and animates 3D scenes and tracks the length of the entire process. The rate at which each test system was able to render the entire scene is represented in the graphs below.
Like many of our previous tests, Cinebench R23 has the Ryzen 7 7800X3D finishing in the expected position, just behind the Ryzen 7 7700X. This is another application that doesn't benefit much from a large L3, so the Ryzen 7 7800X3D's lower clocks hold it back.
POV-Ray CPU Ray Tracing Benchmark
POV-Ray, or the Persistence of Vision Ray-Tracer, is an open source tool for creating realistically lit images. We tested with POV-Ray's standard 'one-CPU' and 'all-CPU' benchmarking tools on all of our test machines and recorded the scores reported for each. Results are measured in pixels-per-second throughput; higher scores equate to better performance.
POV-Ray tells essentially the same story as Cinebench. The Ryzen 7 7800X3D trailed the Ryzen 7 7700X by a couple of percentage points here and even lands behind the previous-gen Core i5-12600K.
Blender Rendering Benchmarks
Blender is a free and open source 3D creation suite that can handle everything from modeling, rigging, and animation to simulation, rendering, compositing and motion tracking. It has a purpose-built benchmarking tool that will track the time it takes to complete rendering a particular model (or models). We used the CPU-focused benchmark with all three models currently available...
We saw more of the same with Blender. The Ryzen 7 7800X3D lands in the lower third, outgunning the Ryzen 5 7600X, but trailing the Ryzen 7 7700X.
Y-Cruncher Multi-Threaded Pi Calculator
Y-Cruncher is a multi-core-capable tool that calculates the value of pi to a specified number of digits. In this case, we ran the tool on all threads and had the application calculate the value of pi to 1 billion digits. The values below are the time required to perform the calculation expressed in seconds. As a result, lower values indicate better performance.
The Ryzen 7 7800X3D lands squarely in the middle of the pack here, beating the Ryzen 7 7700X by the slimmest of margins.

STARS Euler3d Multi-Threaded CFD Benchmark
STARS Euler3d is a computational fluid dynamics benchmark which uses a CFD grid that contains 1.23 million tetrahedral elements and 223 thousand nodes. The benchmark executable advances a mach 0.50 Advisory Group for Aerospace Research, or AGARD, flow solution for an aeroelastic test wing. The benchmark score is reported as a CFD cycle frequency in Hertz.
It falls a bit down the stack relative to the Y-Cruncher results above, but once again we see the Ryzen 7 7800X3D land just ahead of the Ryzen 7 7700X, by a small margin.
This benchmark is multi-threaded, but is also dependent on platform bandwidth, and cache and memory latency, so the final results are not determined by compute performance alone. Cache sizes / speed and memory bandwidth affect the score as well...
