ARM A72 chips use out of order execution, which already gives 3x the performance.

- penagwin 7y agoI'm curious what benchmarks you've seen that actually show a 3x compute improvement? Most of the benchmarks I've seen show a ~30% improvement in CPU compute, while I/O has improved tremendously, as well as the memory. But again I've only seen ~30% improvement in CPU workloads, a far cry from "3x the performance" that I keep seeing.

- BubRoss 7y agoWhat makes you say that? Dynamic languages are usually chasing pointers which is something that out of order execution helps with tremendously.
- megous 7y agoThis is supposedly some TODO app being run repeatedly in Chrome, so it's much more than a JS benchmark. And Chrome as a whole is memory hungry.
