      Because it represents a generalized view of how slow the CPUs are on Android vs iOS. Don't care so much about browser v browser.

      It's a combination of factors including optimization effort, the gameability of the benchmark, and CPU speed.

      And the next gen pixels come out tomorrow, so probably the worst possible time to evaluate pixel perf.

      Tested the 835 chip the Pixel 2 will use. Scored 60-65 in the Samsung S8 and OnePlus 5. Still atrocious.

      Ruby's key insight was to stop this kind of bending over backwards for the compiler and spoil the programmer with beauty they'd appreciate. https://twitter.com/michaelhaeu/status/846545631023894528 …

      In what way is the poor HTML and JS performance on Android helping any users or developers? They’re offering commodity rendering.

      Some ways: more users can afford it; Android vendors don't need to make their own chips.

      Comparing equally priced Android & iOS devices, iOS performance beats the pants off the Androids.

      No one is expecting a $100 Android phone to equal a $1000 iPhone. But it would be nice if $800 Androids weren't 2 years behind iOS perf-wise

      The $349 iPhone SE is TWICE AS FAST as a $900 Samsung S8. That’s just not right regardless of how you slice it.

      Twice as fast according to a benchmark you happen to be fixated on. I share your goal but this tactic makes it worse

          Is there something you don't like about the benchmark? Or the fixation, just?

          Focusing on a single benchmark rarely results in better real world perf. Especially a microbenchmark.

          If difference is 50%, I buy that. But it’s a 500% difference. Even if it overstates real world by 2x, iPhone still more than twice as fast.

          What’s worse: Rate of Android improvement is very low. Nexus 5x: 41 -> Google Pixel: 51 -> Sam S8: 60.

          You don't need a benchmark to tell you js is slower in android. Or does someone has some data showing the opposite ?

          I would supplement with a more "Real Life" benchmark. It's well-known that synthetics are the worst of benchmark types.

          I’m all for benchmark skepticism when differences are small, but a 5x difference in apples to apples comparison has to mean something, no?
