Spectre patch tested on the iPhone 6 - 40% DROP in both single and multi core performance

[Djole123]

So, with the recent Spectre and Meltdown problems arising, companies are hard at work at patching these flaws, with supposed 5-20% drop in performance.

 

Boy, was that an underestimate.

 

A Dutch entrepreneur, Melvin Mughal, tested his iPhone 6 on Geekbench after the 11.2.2 update against the 11.1.1 score he got earlier, and found out that the scores dropped about 40%.

 

So not only are you screwed on the battery side, but also because of the recent patch. Now, this is a single phone with a single update, so we'll see how it goes in the coming days, but if this is true, boy, is Apple screwing you over with the updates.

Ouch.....

 

But this is also geekbench so fuck accuracy

That's the problem. Geekbench is incredibly inconsistent, they should have used a real benchmark.

 

Geekbench sucks

Sure it suffers in a benchmark, but will games/apps/UI experience a difference? The impact for regular desktop users (E.g. using mostly non IO intensive applications) was negligible and most games had a loss under 1%.

For starters, Geekbench.

I'm on 11.2.2 and I'm getting 1498 on single core and 2511 on multi core

Second, WCCFTrash

i didn't know iphones used intel cpu's i always assumed they just use some qualcomm or apple specific processor.

ARM CPUs are also affected.

That's only true if Android devices don't see a similar performance drop.

They don't, the spectre flaw effects a very wide range of processors. What you are thinking of is meltdown which was exclusive to intel.

Edit: well it seems that some processors outside of Intel were impacted.

iPhone 6 uses the Apple A8, which is an ARM v8 based chip

ah, that must be it, i forgot that there where multiple flaws and that only meltdown was intel specific.

Well with the amount of BS spread on this forum attacking just intel. I cant really blame you.

[TetraSky]

Wow... Ouch.

No, certain very high performance ARM implementations also suffer from Meltdown as well. The Cortex A75 is confirmed (by ARM themselves) to be vulnerable to Meltdown. Apple also specifically said that mitigations for Meltdown is included in iOS, implying their custom architecture may also be vulnerable.

 

IPhones use some very fast PCI-e storage, which may explain the hits in benches.

The fact that my iPhone 7 is a slug after the update really concerns me, It’s just over a year old...

If the Android even gets updates.

Exlusively (not big.Little) Cortex A53 based devices won't need any mitigations for Spectre or Meltdown (sounds like the cheesy names news reporters would come up with). Cortex A57, A72 and A73 devices will probably need the mitigations. And Qualcomm is being a absolutely *insert expletive* with info about their custom CPU designs, namely Krait and Kryo. I fear the latter might also be affected by Meltdown.

Dang, this is the first time I'm hearing about that. Sorry about that confusion, earlier reports were suggesting that ARM processors were only effected by spectre.

Your performance should come back after 11.2.5 comes out. The 4th beta made things quite a bit quicker. It also might be worth your time to do a reset on the phone if you can't wait. 11.2.5 should come out very soon.

FYI, you need both the windows update and BIOS update to be protected from meltdown/spectre, so people testing just the windows update will not see nearly as big a drop as people testing with the windows update + the BIOS update

Well, it isn't exactly BS. Intel is the company most affected and the company that has done the most shady things before, during and after. So to call it BS is more misleading than anything else.

Yes, pretty much any modern processor is vulnerable to Spectre to some degree. That's pretty clear. That doesn't detract from Intel being the biggest culprit in this case.

any other sources? WCCF aren't the best at being 100% 

[Whiskers]

Not sure I trust the validity of this claim, at least not yet.

 

I just ran a Geekbench run on my iPhone 7 Plus, and scored a single core score of 3495 and multicore of 5923; within margin of error of my previous test results. I'm currently on iOS 11.2.5 beta 5, too.
