Intel Xeon W-3175X Review: Supercharged 28-Core Skylake-SP

Intel Xeon W-3175X - JetStream, LAME, Blender

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.

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 Xeon W-3175X hangs with the Core i9-7900X and Threadripper 2950X here, but the higher-clocked processors -- especially those based on newer architectures -- pull ahead. This is another test that doesn't benefit greatly from many-core processors, however.

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 particular audio encoding test will utilize only one or two threads, so it doesn't fully take advantage of the additional computing resources available with a many core processor either. As you can see though, the Xeon W-3175X still managed to finish in the upper-third and it outpaces all of the AMD processors.

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 make use of however many threads you can throw at it. You'd think a 32-core / 64-thread processor like the Threadripper 2990WX would be untouchable by a processor with a lower core count, but the Xeon W-3175X eked out a victory here and took the top spot.
