Rumor: iPhone 5 to Feature Quad-core CPU from Samsung

With summer well underway, the Apple rumor-mill is chugging along in preparation for the launch of the next iPhone. Expected to be announced in September, just like the iPhone 4S last year, we don't know a whole lot about the iPhone 5. As usual, Apple is keeping pretty quiet, so we're left to scour the web for talk of the device.

The latest comes via Digitimes and relates to the CPU we can expect to find powering the newest iPhone. The site quotes industry sources in reporting that competition in the quad-core smartphone arena is going to heat up considerably in Q4 thanks to the launch of a quad-core iPhone 5. Not only that, but this new iteration of the iPhone will be running on none other than Samsung's quad-core Exynos CPU.

If this rumor is true, it represents a significant performance increase over the iPhone 4S, which used a dual-core A5. However, we also need to consider the possibilty of an LTE iPhone 5. Right now, quad-core phones generally don't mix with America's LTE networks. For this reason, many manufacturers of quad-core devices have swapped in a dual-core CPU for the American market. This includes Samsung's Galaxy SIII, which uses a quad-core Exynos in international markets but a dual-core Snapdragon from Qualcomm in the U.S. With the launch of the 4G iPad six months ago, we're not sure Apple would choose quad-core over LTE. Still, we could be wrong. Guess we'll have to wait and see.
