With the Samsung Galaxy S5 now out, buyers across the world have wondered how the Korean firm's new flagship compares to its more established Nexus 5 and iPhone 5S competition.
On paper the Galaxy S5 holds up rather well, featuring a custom fingerprint scanner in its physical front facing Home button and custom Knox 2.0 security service designed to make it as enterprise friendly as Apple's iOS-powered iPhone 5S.
Under the hood it also has a number of radically upgraded internal specifications that should let it match, or beat, the iPhone 5S' and Nexus 5's performance. Key additions include a reworked 16MP rear camera sensor, latest generation, quad-core Snapdragon 801 processor and Full HD 5.1in Super Amoled display.
However, as we all know, specs don't always ring true with real-world testing and occasional flies in the ointment can hamper the performance and user experience of even the mightiest of smartphones.
To see how the Galaxy S5 actually performs against the iPhone 5S and Nexus 5 we've pitted the phones head to head in a series of speed test challenges, designed to see how they actually perform when challenged with real-world tasks.
