AMD Ryzen Threadripper 2920X And 2970WX Review: Lower Cost, Many Core Beasts

Ryzen Threadripper 2920X And 2970WX - JetStream, LAME, And Blender Performance

Next up, we have some numbers from the JetStream Benchmark Suite developed by WebKit. The JetStream Benchmark Suite uses a wide array of latency and throughput benchmarks to evaluate JavaScript performance, and all of the results are tabulated with roughly equal weighting. The benchmark measures both metrics of traditional JavaScript programming styles used on websites as well as new JavaScript-based technologies used on more modern, rich web applications. Scores in this benchmark are an indicator of the performance users would see when browsing and running advanced web applications.

JetStream JavaScript Benchmark
JavsScript Performance Testing

All of the systems were tested using the latest version of Microsoft's Edge browser, with default browser settings, on a clean install of Windows 10 Professional x64.

The latest Threadrippers finished about in the middle of the pack here. Not much separates the many-core processors in this benchmark and the majority of their resources go unused, hence the relatively strong performance by the higher-clocked, mainstream Intel Core and AMD Ryzen processors.

LAME MT
Audio Conversion and Encoding
In our custom LAME MT MP3 encoding test, we convert a large WAV file to the MP3 format, which is a popular, day-to-day use case for many end users, to provide portability and storage of their digital audio content. LAME is an open-source mid to high bit-rate and VBR (variable bit rate) MP3 audio encoder that is used widely around the world in a multitude of third party applications.

In this test, we created our own 223MB WAV file and converted it to the MP3 format using the multi-thread capable LAME MT application in single and multi-thread modes. Processing times are recorded below, listed in seconds. Shorter times equate to better performance.

This benchmark utilizes only one or two cores, hence the tight grouping of Threadrippers and the strong performance by Intel's highest-clocked Coffee Lake processors. The Threadripper 2920X's relatively high clocks versus the WX-series processors does shave a couple of seconds off the encoding process, however, and pushed it up the stack a few notches.

Blender
3D Rendering Benchmark

Blender is a free and open source 3D creation suite that can handle everything from modeling, rigging, animation, simulation, rendering, compositing and motion tracking, even video editing and game creation. It has a built-in benchmarking tool that will track the time it takes to complete rendering a particular model. We used a CPU-focused BMW model for these tests here...

Blender will take advantage of as many cores / threads as you can throw at it, and as a result, the Threadripper 2970WX finishes near the top of the heap, behind only the 32-core Threadripper 2990WX. The 2920X puts up a strong score as well, that easily outpaces the much more expensive Core i9-7900X and recently introduced 9900K.
