    At the heart of this suite is the ARM Cortex-A72 processor, which is the highest performing CPU technology available for developing mobile SoCs today. In target configurations, the Cortex-A72 processo...

    ARM is closing the performance gap with Intel quickly and efficiently than we all thought, which is after all a good thing. I am really amazed with such high performance that too with traditional power efficiency of ARM processors. All the best ARM.

    They could launch a new processor every year if they want, but i still can´t tell the difference in performance between an S3 and an S5 for example.

    Small apps you really won't notice a difference for a few reasons.

    1. If it's a game it's because of the resolution difference, there needs to be a way to test the two devices with the same resolution.

    2. Some apps really don't require a whole lot.

    What you will notice the difference in, are benchmarking apps, apps that requires higher extensions(Such as Dolphin and Open GLES 3), or productivity apps such as Office or Google Drive apps.

    You would notice it better too if there were better apps to monitor usage on Android like there are on Windows built in.

    True, but for the average user, which probably means 90%, it´s just the same thing with a bigger screen.

    Note one thing, no one of thoses slides, informations about the A72 speak about performance gain over previous architecture, but power efficiency at some arbitrary power level. Marketing slides are sometimes ( offtly ) a bit missleading

    Not in the enterprise field.

    We had to upgrade our Ipad and Ipad 2's because both the Google apps and Microsoft Office apps did not run correctly on the devices, as well as a few of our devices did not support them.

    As long as new releases of ARM processors don't consume more power than their predecessors, I say keep up the work. Otherwise - STOP!!! When the Cortex A15 was released, sure, it was a nice model, but its power efficiency was just too high for phones. It was ok for HTPCs and tablets, but the reason ARM made so much success was because of phones.

    I don't need a phone more powerful than my office computer. I need a phone with a reliable battery and performance good enough to get me through my day.

    " the Cortex-A72 processor will deliver CPU performance that is 50X greater than the leading smartphones from just five years ago. "

    Is the X factor based on the CPU's clock speed? I had a Motorola Droid X (2010 Model) with a Cortex-A8 @ 1Ghz. How would the (X-Greater) be calculated here?

    Many factors.

    Number of cores, efficiency of cores, cache sizes, any new extensions. Really you would just have to look at the die of the SoC to know.

    The uses for ARM have increased because of the power increase of ARM systems. I mean you even have servers that are ARM based now.

    For power draw, the A15 was never meant to be just an SoC for phones. It was made for mobile devices, and while the final power draw was higher than compared to the A9, A15 did feature more power saving techniques to where the increase in highest power draw didn't make any difference.

    Also look at Nvidia, they aren't in the mobile phone world anymore since their ARM SoC's use too much power for one.

    Do you own both? I've seen a massive difference just between an S3 and an S4 (though comparing Samsung phones in everyday performance isn't the best benchmark as the Touchwiz UI has always been a laggy mess)

    Let s not compare phones please.
    Here at guru3d wi do not compare processors for how windows runs on them.
    Because you now, phone is a soc, but still touchscreen and flash memory and ram is paried by the vendor.
    Also.. for s3 and s4 maybe he was referring to the snapdragon models?


    With this power efficency maybe we will see soon 512 cores affordable servers :) with all this virtualization fashion they could be a nice deal.
