CPU Performance

Now that we have a good idea of what the A8 SoC looks like, we can talk about performance. While we covered this in the preliminary article, it’s worth going over again. For those that are unfamiliar with our test suite the CPU-based tests are mostly browser-based benchmarks. Once again, although I’m not quite happy with the state of benchmarking things we’re getting close to a more platform-agnostic solution.

For the most part, the A8 SoC performs admirably despite the relatively low (1.38 GHz) frequency and half the cores when compared to competing SoCs. It seems that this is mostly building upon the lead that A7's Cyclone CPUs began. It remains to be seen if other SoC manufacturers will catch up in their CPU architecture at one point or another (NVIDIA's Project Denver in particular is interesting), but for now Apple seems to be quite far in the lead in CPU performance.

    Inevitably stop working? If you really have that many cable failures maybe it's the Radio Shack cables that are the problem? I've never heard of one of them failing. Maybe try Monoprice. They have a line with metal housing on the connectors and they're cheaper than the Apple ones.

    I just use the ones that come in the box with the iPad or iPhone. Cost = free :)

    I've never had a cable failure with any Apple cable, except those I abused (and even most of those are going strong 2-3 years later). If your wife's cables are failing predictably, it has something to do with how it's being used. That's not to say she's mis-using it - it may simply be that her use involves additional strain. Perhaps she uses a car mount or other device that kinks the cable at the end?

    in my experience, both micro usb and lightning crap out after some use. The only difference is that it cost on average 4-5 times as much to replace a Apple cable.

    Actually, I've never had a problem with the 30-pin connector (I believe they replaced it mostly for size reasons), nor with microUSB. I'm somewhat unconvinced there's a strong argument for Apple not to use microUSB. There may be one, but I've not heard it.

    How is the lightning connector defective? Personally I love it. It has no pins to break like a USB connector, does not have to be inserted in one specific direction, and works quite well overall.

    I don't think Apple are interested in the low end. Apple's strategy is to make fewer devices, but more profit from each one. It seems to be the best strategy.

    They bend after applying 70 lbs of force. Thats a LOT.

    Can you bend them by hand? sure

    But it's not possible to bend them unless you were TRYING to damage them. Ie, during normal use they shouldn't bend.
  • GerryS - Wednesday, October 1, 2014 - link

    Agreed. I feel certain I could also bend my laptop screen if I wanted. I don't want.

    The only people that don't like the Lightning connector also don't own any Apple devices that use one.
