AMD Spring CPU Refresh: Ryzen 7 5700X And An Affordable Ryzen 5 Trio Tested


AMD Spring Ryzen Refresh: 3D Rendering, Audio and Video Encoding

In our custom LAME XP MP3 encoding test, we convert 16, large uncompressed WAV files to the MP3 format, which is a popular use case for many end users, to provide portability and storage of their digital audio content. The LAME engine is an open-source MP3 audio encoder that is used widely in a multitude of third party applications.

LAME XP Audio Encoding

In 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.

To this point, we've seen a somewhat predictable performance trend. In our custom audio encoding test, the Ryzen 5 4500, 5500 and 5600 once again fall-in just behind the Ryzen 5 5600X (as you would expect) and the Ryzen 7 5700X notches another victory over the Core i5-11600K.

x265 Video Encoding Benchmark

The multi-threaded HWBOT x265 Benchmark is based on the open source x265 encoder that leverages modern CPU instructions to speed video encoding. We tested the CPUs represented here with the 64-bit encoder using the default 1080p and 4K workloads.

The x265 video encoding benchmark had the Ryzen 5 4500 trailing the Core i5-11600K, whereas the Ryzen 5 5500 and 5600 pulled ahead. The Ryzen 7 5700X, however, clearly outran the Core i9-11900K and finished just behind the Alder Lake-based Core i5-12600K.

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.

Our Cinebench R23 results had one minor hiccup / anomaly in that the Ryzen 5 5600 just barely edged out the 5600X in the multi-threaded benchmark, but we'll chalk that up to somewhat better thermals for the newer chip, which allow it to maintain peak all-core clocks for slightly longer durations. The rest of the new processors fall in-line with expectations.

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.

Our POV-Ray results tell the same story as Cinebench. Once again, the 5600 and 5600X are right on top of each other in the multi-threaded test, with the 5600 just barely scoring a win, but the Ryzen 5 4500 and 5500 and Ryzen 7 5700X slot in right where their branding suggests.

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.

No surprises here -- the Ryzen 7 5700X finishes right on-par with the Core i5-11600K and the new Ryzen 5 processors fall in line just behind the Ryzen 5 5600X. Note, however, the massive performance increase offered by the 5500 and 5600 over the 4500, which is based on an older architecture.

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.


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...

As expected, the new Ryzen 5 series processors fall in-line just behind the Ryzen 5 5600X again here and the Ryzen 7 5700X slots in between the two 11th Gen Core processors.
