SAMSUNG UNVEILED its Galaxy S5 flagship smartphone at Mobile World Congress (MWC) this week, and it's no doubt hoping its specifications will tempt buyers away from Apple's iPhone 5S.
While the two smartphones have similar names, they have different hardware and software, and are both looking to win the affections of punters in the market for a top-end smartphone.
We have lined up the two smartphones head to head on paper to find out which one comes out top in terms of specifications.
Design, measurements and weight
iPhone 5S: 124x59x7.6mm, 112g
Samsung Galaxy S5: 142x73x8.1mm, 145g
The iPhone 5S is both thinner and lighter than Samsung's Galaxy S5, measuring 7.6mm thick and tipping the scales at 112g. The Galaxy S5, in comparison, measures a slightly chunkier 8.1mm thick and weighs 145g.
The smartphones are very different when it comes to design, too, and it's likely that most buyers will have their favourite. The iPhone 5S is made entirely of aluminium, giving it a top-end look and feel, and it features an angular, boxy design. It's also available in three colours - black, white and gold.
The Samsung Galaxy S5, on the other hand, has a fully plastic casing, which Samsung has perforated on the back to make the device comfortable to hold. The flagship smartphone is available in four colours - black, white, blue and gold.
Interestingly, both devices feature a fingerprint sensor in their respective home buttons, and are the first two smartphones that do. This adds a layer of security to both the iPhone 5S and Samsung Galaxy S5, and makes the devices quicker to unlock.
While they both feature a fingerprint scanner, the Samsung Galaxy S5 trumps the iPhone 5S with its IP67 certification, which means that unlike Apple's flagship smartphone, it is resistant to dust and waterproof. The Galaxy S5 also has a heart rate monitor on the back, a feature that likely will interest fitness fanatics.
iPhone 5S: 4in 640x1136 resolution IPS LCD Retina display, 326ppi
Samsung Galaxy S5: 5.1in 1920x1080 resolution Super AMOLED display, 432ppi
The iPhone 5S features a display that's identical to that of its predecessor, the iPhone 5, and this was long regarded as the best screen you could get on a smartphone. Measuring 4in, the display features 640x1136 resolution and a pixel density of 326ppi, and thanks to its IPS technology it is among the best when it comes to viewing angles. However, with smartphone screens becoming larger all the time, some might consider the display too small.
Those that do might be pleased by the display on the Samsung Galaxy S5 - a 5.1in 1920x1080 resolution Super AMOLED screen with a higher pixel density of 432ppi.
