JetStream And LAME MT Tests

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.

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 higher-clocked, SpeedShift-enabled Kaby Lake-based Core i7-7700K took the overall lead here, but the Core i7-6700K, 6900K, and 6950X weren't that far behind. The next three in-line, however, were the AMD Ryzen processors, which notched in just ahead of the Core i7-5960X and older FX 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.

The entire Ryzen 7 line-up performed well here. Their single-threaded results weren't spectacular, but still represent huge performance gains over the FX and A10 series parts. Multi-thread performance (which utilizes only two threads in this test) scaled well though, and pushed the Ryzen processors up the charts a bit. Not, that it was only Intel's highest-end processors that outran Ryzen here.
