These tests were performed in Chrome 75 on Windows 10 1903 with all updates installed and all hardware vulnerability mitigations active.
Even though Intel still holds a solid lead in Jetstream, the massive improvement from the Ryzen 7 2700X to the Ryzen 7 3700X is praiseworthy. Other tests see similar score uplifts, with AMD even claiming the Kraken benchmark. Performance gaps between the Coffee Lake and Zen 2 processors in these benchmarks seem to correlate with clock rate, which is quite a win for AMD.
The WebXPRT 3 benchmark is meant to simulate some realistic workloads one might encounter in web browsing. It’s here primarily as a counterweight to the more synthetic microbenchmarking tools above.
Once again, the difference here seems to mostly be down to clock rates.
Webassembly, often abbreviated to “Wasm,” was created by an assortment of browser builders in cooperation with the World Wide Web Consortium (W3C) with the intention of producing a portable binary format and programming language for high-performance web applications. PSPDFKit’s WASM benchmark simulates real-world Wasm workloads, and is intended to give an impression of a given machine and browser’s performance in the new format.
