    Okay, I just watched this video and I can’t get my head around it. Around 08:30 he starts comparing the performance of both phones by opening Minecraft. The 8 Plus was a bit faster but as he says it might be down to the fact that A11 ramps up to it’s full power faster than A12. Fine, makes sense, it was a short task anyway and the difference was negligible. However then he proceeds to the “mother of all phone processors test”, the exporting of a mighty 4K 60 video. I felt that here the A12 should shine since it’s a very demanding task which needs more time. More than enough time for A12 to show it’s brute strength, right? Well, the 8 Plus starched the XR again, with a considerable difference I might add. So what gives? How’s this possible? Is it an optimization issue or what? This is kinda important for me because I edit small (but hefty) GoPro videos on my phone all the time. My 7 plus is very good at it and while I’m contemplating the jump to the XS or XR I need to know that their power is not on paper only.

    See Round 1. XS beat X.



    And for extra credit...XS is currently the speed champion on Phonebuff speed test:

    That's because they are using a (Product) Red phone for the 8. Red makes it faster.
    :p

    can someone explain why speed matter so much? everytime i upgraded my iphone, it was because either size/battery life. it was never because of speed

    To me, speed matters when to no longer have it. What I mean is as the phone ages and newer versions of iOS gain more functionality, the phone feels slower than when new.

    A phone that was faster when new would likely be faster as it ages. A phone that's slow when new will be awful at year 3.

    'Da Red Goes Fastah' indeed, but they used XR red as far as I can see :D

    It’s one data point and could be the result of many factors.

    Lol, right? It’s hard to understand what exactly is going on. If the A12 takes more time to come to full speed in order to improve efficiency and battery life then it’s not exactly faster(as advertised) but more efficient. I am aware of the benchmarks and yes, there are a lot of videos where the A12 seems faster (not by much) but in this case, with the 4K video export, it’s simply inexplicable. The A12 should run circles around A11 in any circumstances and in any case scenario.

    They don’t state storage size comparisons in the OP thread. If the 8+ has 256GB that could explain the speed difference since the 256GB models have faster memory than 64GB and 128GB models.

    Is
    That true even on the XR? I’m wondering because my XR rarely crosses 11,000 On Geekbench 4. It’s high 10,000s so I’m not complaining just wondering if that may be why I’ve never seen the scores people are posting in the 11,200-11,400 range.

    This may very well be due to optimization. I remember EverythingApplePro did the same export test last year with the 7 Plus vs the 8 Plus and the 8 Plus lost to the 7 Plus and he mentioned it was due to optimization.

    Really, is that so? Glad to hear! I have a new 256 Gb Product Red 8 on the way.

    Thanks, I kinda forgot about this. Memory speed definitely is a factor here. Nevertheless, I’m gonna pull the trigger on a 128 black XR, the same storage as my 7 plus. I expect faster exporting times than my 7 plus because the storage speed should be the same and the the rest is down to the different processor. Also, I assume that optimization plays a role, usually it takes at least three to four months of “polishing” for these app to utilize the new hardware to it’s fullest potential.

    I would compare both setting them as new phones, cause sometimes weird stuff happens from restore.
    That way we could tell if its a hardware or software issue.

    Otherwise it could be that Apple is using a slower nand on the XR, but since is the only case ive seen of A11 beating an XR i doubt it.
