• Tests Confirm the Marginal Difference Between the A9 Chips Made by TSMC and Samsung



    Recently published battery test results appear to support Apple’s claim of little difference in the longevity of an iPhone 6s when comparing an A9 chip made by Samsung to one that is manufactured by TSMC. During the tests, TSMC’s chip performed marginally better when it came to Wi-Fi browsing and GFXBench tests but actually ended up ranking a few points lower in WebGL scores.

    It should be noted that the test was conducted by the folks at Ars Technica where the site testers used two SIM-less AT&T phones, with each set to the same display brightness.

    Overall, the TSMC Model did do substantially better in Geekbench 3, moving past Samsung by roughly 28%. That being said, Apple did complain previously about Geekbench being “unrealistic” because it forces a phone to operate at peak CPU usage until its battery dies. The folks over at Ars concluded that under extremely CPU-intensive tasks, Samsung’s A9 chip can become a detriment.

    When it comes to the whole ordeal, just last week, Apple insisted that there should be no more than a 2%-3% battery life gap between any two comparable 6s models. Some anecdotes hinted that the difference could be one that is as large as two hours.

    Just as a reference, it should be mentioned that TSMC’s version of the A9 chip is manufactured using a 16-nanometer FinFET process whereas Samsung ends up depending on a 14-nanometer technique instead. Smaller process sizes typically result in more efficient chips.

    Despite being marginally better, an improvement is still an improvement!

      Nobody minds the GeekBench test when it suggests that the new iMac is 20% faster than the old one though?

      LOL This is the same model iphone though
      they aren't comparing 6 and 6s but 6s with 2 different chips.

      Glad I've got the TSMC

      I guess an improvement is still an improvement but this whole thing has still been blown out of proportion. That difference is not going to matter in the real world because everyone uses their phone differently and certainly not at top performance until the battery dies. If my 6s has a Samsung chip my phone could still last longer than someone's phone that has the TSMC chip. NOT A BIG DEAL!

      So what? The point is it’s acceptable when it suits them.

      Huh!?!?!? It sound like you are grasping straws with this one.

      No idea, what you’re talking about. Doesn’t sound like you do either.
