I tried this benchmark in Chrome on 3 computers: * 6 year old Macbook Pro i7-4980HQ, Windows 10 - 102 * 5 year old Macbook Pro i7-5557U, OS X - 100 * Threadripper 2990WX desktop - 99 So, uh, I might have some questions about this benchmark's general validity now?! - though maybe it is some evidence in favour of my vague feeling that the Threadripper sometimes doesn't feel as fast as it seems like it ought to feel.

The Jetstream benchmark is made by the WebKit team. Its scores will vary per browser, so you have to compare browser to browser. I compared an iPhone 11 running Safari to a MacBook Pro running Safari. Apples to apples. Moreover, while the Threadripper 2990WX is a really awesome processor, single core benchmarks (I think Jetstream is mostly limited to a single thread) aren't particularly its strength. Over multiple runs it should beat your Macbook Pro, but not by a huge amount. If not, take a look at how you're cooling that beast :)

  iOS Safari and desktop Safari aren't identical.

    Okay, thanks? Two actual apples are never identical either, but they're still more comparable than to oranges.

  I updated a six core i7 3930k with a sixteen core 1950x threadripper on one of my boxes. Biggest reason for the update was the disk IO (m2 drives) and number of cores and I'd had the 3930k since the launch day at Microcenter. On Windows, single threaded at stock speeds, the cores were comparable from a 6-8 year gap between the two CPUs. For hosting virtual machines... the speed did not matter as much as having an abundance of physical cores. Still - I was not expecting the 'core speed' as reported by a video game to be as close as it was. The Zen2 (3900x) core speed on the other workstation reported as almost twice as fast, with 12 cores. Really wish that TR4 board supported the 39xx threadripper series.

I don't think a threadripper would be expected to have particularly good single-threaded performance?

  Zen 2 was a big uplift in single-threaded performance. Ryzen and Threadripper 1000- and 2000-series, and Ryzen Mobile < 4000-series are all on Zen or Zen+ architecture. The current gen Ryzen and Threadripper 3000-series and the Ryzen Mobile 4000-series are the ones running on Zen 2. This is where AMD is competitive with Intel on single-threaded workloads, largely across the board. Parent mentioned a 2990WX, which is a Zen+ part.

    Oh, right; didn't realise Zen 2 ones actually existed yet.

  It's the opposite. The latest generation of ThreadRipper is not only ahead in multicore peformance it is also comparable to the highest possible single core performance from the regular Ryzen Lineup.
