AMD Ryzen 5/7/9 7000 65W Tested: Low Power, High Performance

AMD Ryzen 5/7/9 65W Processors: 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 common 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

For this test, we created 16-copies of our own 223MB WAV file (an 11-minute Grateful Dead jam) and then converted it to MP3 format using the multi-threaded LAME XP tool. Processing times are recorded below, listed in minutes:seconds. Shorter times equate to better performance.

There weren't any surprises in our custom LAME XP audio encoding test; the new 65W Ryzen processors slotted in just where you'd expect. What's perhaps most interesting is the leap in performance over the previous-gen 5000 series. The Ryzen 9 7900 actually outpaced the Ryzen 9 5950X here, despite the latter's increased core count.

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.

The Blackmagic Raw Speed Test also had AMD's latest lower-power Ryzens finishing just behind their higher-powered counterparts, with only a couple of percentage points separating the various chips. 

Cinebench R23 Rendering Benchmark

Cinebench is a rendering performance test based on Maxon's Cinema 4D, which is a 3D rendering and animation tool suite used by animation houses and producers like Sony Animation and many others. It's very demanding on system processor resources, and it can utilize any number of threads, which make it 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.

Cinebench tells of more of the same. The new 65W Ryzen processors finished just where you'd expect based on their branding. And the Ryzen 9 7900 continues to trade blows with the previous-gen flagship Ryzen 9 5950X.

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 chips' positioning in the chart are mostly unchanged -- the only difference is that the Core i5-12600K was able to inch out in front of the Ryzen 7 7700 here.

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...

Yet again we see the new 65W Ryzen processors slotting in just behind their X-branded cousins. There's a few different systems and processors in this chart, but the ultimate trend remains unchanged. Despite their lower peak power, these new 65W Ryzens offer relatively strong performance.
