the versions he's testing are like 3 updates apart so it's entirely possible that the regression isn't even due to 11.2.2, if it exists at all.

I think more people would be screaming if it’s that bad wouldn’t geekbench’s database be the best place to check?

Updates often trigger a re-index which will jam up a core for a while (almost like that's 50% of your phones processing power 🤔)

Stereotype posted:A lot of those look pretty "daily use" to me. JPEG, HTML5 parsing, PDF rendering, all down like 40%. seems like any camera accelerator worth a poo poo would have hardware jpeg encoding, that shouldn't drop off at all due to cpu performance. at least every camera accelerator i have tested has had it, and i have worked on 3 of them.

genius yospos solution to avoiding the spectre bug is to get a phone with an operating system that will never get updated against the spectre bug

BangersInMyKnickers posted:The sample size is 1 so maybe reserve judgement for a little bit i tried geekbench 3 on my iphone 7 and it's identical to the original performance of 10.0. i think something else is going on with that idiots phone, or maybe it only affects older iphones. it probably thermal throttled after sitting there updating to the new ios for 20 minutes and then he immediately ran the benchmark, or it was doing some background post-update housekeeping tasks while it was running. whatever it is, that article is fud.

BULLSHIT. Have you _looked_ at the patches you are talking about? You should have - several of them bear your name. The patches do things like add the garbage MSR writes to the kernel entry/exit points. That's insane. That says "we're trying to protect the kernel". We already have retpoline there, with less overhead. So somebody isn't telling the truth here. Somebody is pushing complete garbage for unclear reasons. Sorry for having to point that out. If this was about flushing the BTB at actual context switches between different users, I'd believe you. But that's not at all what the patches do. As it is, the patches are COMPLETE AND UTTER GARBAGE. They do literally insane things. They do things that do not make sense. That makes all your arguments questionable and suspicious. The patches do things that are not sane. WHAT THE F*CK IS GOING ON? And that's actually ignoring the much _worse_ issue, namely that the whole hardware interface is literally mis-designed by morons.

Too much effort, they're deprecated CPUs anyways, and we can now hold a gun to people's heads about security and jack the price of our current gen which is compatible with our patches, and next gen procs through the roof!
