Not one to be left out of the fun, Samsung’s head of mobile, JK Shin, explained that future Galaxy-branded devices will have 64-bit chips not dissimilar to the A7 found in the iPhone 5S.
Apple announced on Tuesday that the iPhone 5S will be the first mobile device to ship with a 64-bit CPU and instruction set, explaining that it adds a significant amount of processing headroom to the platform. Developers will be able to optimize their apps for the 64-bit chip in Xcode, but it’s not clear whether the same will be necessary on Android.
Samsung derives its chips from two places: its own Exynos solution, which has recently adopted ARM’s Cortex-A15 chipset and, using big.LITTLE, added four Cortex-A7 chips for low-power use; and Qualcomm’s Snapdragon chipset, which is a variation of ARM’s flagship line with energy optimizations and, in many cases, a built-in baseband. It’s not clear whether Shin is talking about Samsung’s Exynos or Qualcomm’s Snapdragon going 64-bit first, but there is reason to believe it’s the former. End users likely won’t notice the benefit of that expanded pipe for some time, but as Android devices approach 4GB of RAM, such chips will become necessary.
Shin intimated that the changeover may not happen for a while, but we’ll likely see 64-bit chips in the next year.
