SilverBench v2.0… .js edition

How does it work?

• We are using JavaScript Web Workers. TL;DR Use any browser, any version (Chrome, Firefox, Edge, etc.). If using Internet Explorer, 10+ is required. TS;WM To run the benchmark, you need a browser with HTML5 Web Worker support. All browsers supported this a long time ago (for example, Google Chrome since 2010), with a notable exception - Internet Explorer, which requires at least version 10.
• Browser's .hardwareConcurrency feature is required by our rendering engine. Internet Explorer (even the latest Internet Explorer 11) does not support this at all. And it ships with Windows Server 2019! Uh!? So, we emulate / simulate :) And it somehow works.
• We are rendering exclusively using CPU. It does not matter what GPU (video card) you have. It will not affect the rendering speed, and thus, the final score.
• Browsers tend to limit how many Web Workers a single page can create. 32/64 threads should be fine, though.

Explain

• Performance test renders 1 frame, Extreme - 10 frames. Stress test never ends. It runs all cores at a maximum full 100% usage until stopped, making it an awesome CPU burn test.
• Performance and Extreme scores are submitted by a user. Stress score is submitted automatically after the 10th frame. Result is shown at frame 13th.
• Intel i7-6700K @ 4.00GHz CPU performance benchmark score is about P20000.
• Samsung Galaxy Tab S 8.4 (2014) performance score is about P2000.
• Huawei Mate 20 Pro (2018) performance score is about P9500.
• Intel i7-6700K @ 4.00GHz CPU extreme benchmark score is about X2000.
• Intel i7-6700K @ 4.00GHz CPU stress benchmark score is about S0.0700 (FPS).
• Multiple CPU sockets will increase overall performance.

What do these benchmark numbers mean?

• For the Stress test a score represents FPS (frames per second). For example, score S0.1886 indicates that about 5.3 seconds is required to render a single frame. At score level S1.0000 - exactly 1 second is required to render 1 animation frame. At score level S2.0000 - computer is able to render 2 frames per second.
• Both for Performance & Extreme tests results are relative to time needed to render a complete scene (all animation frames). For example, result P33454 is about two times faster than P17000.
• The Performance score is relative to the Extreme score with a factor of 10. For example, score P33454 and score X3356 indicates that both machines can render the animation frame at the same speed.

Known limitations (as of November 2018)

• Edge is slow. About 2 times slower than Chrome / Chromium.
• Firefox is super slow. About 10 times! Uh?
• Firefox only reports max 16 cores via .hardwareConcurrency property. This is due to the .maxHardwareConcurrency limit. Use + and - keys to adjust the correct core value.
