Neither the iPhone 6 nor the Samsung Galaxy F is even out yet, but the rumor mill is busily churning out speculations about both of them. Apple Inc. (NASDAQ:AAPL) has been facing off with Samsung Electronics Co., Ltd. (LON:BC94) (KRX:005930) for years, each trying to outdo each other. So how will the iPhone 6 and the Galaxy F—which, by the way, we don’t even know exists—stack up to each other? Let’s examine what people are saying.

iPhone 6 Samsung Galaxy F

Now let’s be realistic here. We’ve seen neither one of these handsets, so all we’re really doing here is comparing the rumors. But anyway, let’s get started.

iPhone 6 and Samsung Galaxy F design

Both handsets are expected to feature metal casings. Apple Inc. (NASDAQ:AAPL) has been using metal backings for years with the iPhone, but Samsung Electronics Co., Ltd. (LON:BC94) (KRX:005930) has stuck with plastic. Fans have criticized the plastic backing, and there have been rumors about a metal-backed Galaxy smartphone for years. When we started to hear about an even more premium handset from Samsung, a metal backing just seemed to make sense. The company could have thought it was too expensive to use metal in its flagship Galaxy S5.

And then there’s the matter of the display size. Apple Inc. (NASDAQ:AAPL) is rumored to be working on two sizes of the iPhone 6. One is expected to have a 4.7-inch display, while the other could be a phablet-sized 5.5-inch display. There are mixed reports about whether both sizes will come out at the same time, however. Meanwhile the Samsung Galaxy F is rumored to be falling right in between, at 5.3 inches.

Other possible features

Many of the iPhone 6 and the Galaxy F’s rumored features are comparable. Apple Inc. (NASDAQ:AAPL) started putting 64-bit chips in its iPhones with the 5S, and Samsung Electronics Co., Ltd. (LON:BC94) (KRX:005930) has suggested that it could move to 64-bit chips later this year or early next year. Depending on when the Galaxy F comes out, it could have a 64-bit chip. Both smartphones are also expected to offer biometric security in the form of a fingerprint sensor, just as their most recent predecessors have.

One place where the two phones significantly diverge is in the camera. Some have suggested that the Samsung Galaxy F will have a 20.7-inch megapixel camera, while the iPhone 6 could stick with the same 8-megapixel camera that’s been in previous models.
