Leading browsers had moved to 6-week update cadence by 2011 at the latest , routinely delivering fixes at a quick clip. This lack of transparency is by design and provides Apple deniability while simultaneously setting low expectations, making them easier to exceed. What choice do developers have, but to sit and stew? But needs must.

I said something similar to the above, but with two important differences: I said hardware “threads,” not only hardware “cores” – it was about the amount of hardware parallelism available on a mainstream system. Longer answer follows: Here’s the main part from article, “Design for Manycore Systems” (August 11, 2009).

Hardware Past As Performance Prologue. If those specs sound eerily familiar, it's perhaps because they're identical to 2016's $200USD Moto G4 , all the way down to the 2011-vintage 28nm SoC process node used to fab the chip's anemic, 2012-vintage A53 cores.
