I thought the 9.7" Pro was under-clocked? Anyone else?

    After almost 30 days of back and forth I decided to return my 12.9 and swap it for the 9.7 Pro. I ran Geekbench just to compare it to the 12.9 and the 9.7's processor is listed at a higher speed than the 12.9. The scores are pretty much what everyone else is seeing so I am guessing this is a geek bench error.

    Just wondering if anyone else has the same thing pop up for them?

    For me:

    12.9"
    2.24 GHz
    3222 Single Core
    5485 Multi-Core

    9.7"
    2.26 GHz
    3078 Single Core
    5285 Multi-Core

    Both iPads are on the same iOS and update of Geekbench.

    benchmarks there seem consistent with what people found, 9.7 is roughly 100mhz? "slower" than 12.9

    how anyone could care, is beyond me.

    now 4gb vs 2 for ram, that i could see

    Yeah, I don't care. Just a bit surprised that my 9.7 Pro lists a higher clock speed than the 12.9.

    Very possible your 9.7 was plugged in while running Geekbench

    It wasn't. Just got it today. Didn't charge it yet. Oh well!

    Apple says it's slightly underclocked, but with the smaller screen as compared to the 12.9 I think it's comparable or faster slightly.

    Now that I am looking online I am seeing a few different clock speeds.

    2.16
    2.18
    2.26

    But all the 12.9's seem to be at 2.24 GHz.

    Interesting either way.

    2.25 for me, but pretty much identical scores to yours.

    Or who making the Chips much like the iPhone 6s Plus some SKU's had the A9 CPU made by Samsung or the same A9 CPU made by TSMC which were 2%-3% faster.

    I wonder who makes the A9X CPU my guess is TSMC

    I've had beer but... Would the 12.9" not need a bit more oomph to run the 12.9" retina screen?

    *typed on one 12.9" Pro owned for a week tomorrow. Laptop hasn't seen light in this week. ☺️

    Yeah, your beer hasn't affected you that much ;) It takes a bit more oomph under the bonnet for the 12.9" Pro just to throw around those extra 2.5 million (ish) pixels compared to the 9.7".

    Guess this has already been addressed, A9X wiki says the max clock speed ranges between 2.16-2.26GHz

    What is interesting is that the range of reported clock speeds on the 9.7 seems to have no bearing on performance based on the actual benchmark scores. They are all consistent and consistently lower than the 12.9 (which is fine). So I wonder if the clock speed is simply misreported by geek bench or the chips are all throttled to maintain similar performance regardless

    Based on everyone running the same version of iOS and geek bench I would think its the latter, but who knows!

    On iOS 9.3.1 my geek bench reports 2.24ghz. Latest beta iOS is reporting 2.26ghz.

    Thought I'd run mine. 12.9"

    I'm curious if any of you have run the 3DMark Sling Shot Extreme benchmark? On two iPad Pro 9.7's I've run it on the results have been around 2300, significantly lower than the supposed 3000 average. Which makes me wonder if the 3000 includes results from the iPad Pro 12.9 or if it's the old results for the non extreme version of Sling Shot.

    (First photo iPad Pro 9.7 with 256GB, second one with 128GB, last iPad Air 2)

    A different run after I'd let it cool a while did manage 2600 (first iPad Pro 9.7 256gb, second 128gb)

    But a run a short ish time later was again around 2300 (again first iPad Pro 9.7 with 256gb, second with 128gb)

    I can post the results of my pro's a bit later (didn't grab a screenshot of those results). Both were consistently in the 3020-3080 area for single core. One iPad came running 9.3, the other 9.3.1, one says its 2.24ghz and the other 2.25ghz.

    Okay so I can get to 3000 on both devices if I switch off Demo mode first, running the demo first seems to throttle the iPad (again first is 256gb IPad Pro, second 128GB version)
    image.png image.png

    Comparing the Pro and the Air 2 repeating the Sling Shot Extreme benchmark without demo over and over 11 times one after another) that the Air 2 is throttling more slowly than the 9.7" Pro and seemingly less harshly. (iPad Air 2 only dropping 140 points over 11 runs, where the iPad Pro 9.7 dropped nearly 500 points over the course of 11 runs)

    Both devices at same brightness level 50%, volume at zero, wifi on, mail checking set to manual.

    Code:
    Pro 9.7               Air 2
    3088                  1932
    3027                  1917
    3050                  1918
    2862                  1923
    2929                  1929
    2768                  1926
    2670                  1904
    2741                  1875
    2621                  1825
    2716                  1800
    2600                  1793
