There's yet another version of the Samsung Galaxy S4 on the cards, and it's even faster.
The benchmarks register a Qualcomm quad-core Snapdragon 800 processor clocked at 2.3 GHz. The model number is I9506.
The current version of the S4 boasts a 1.9GHz quad-core Snapdragon 600 chip in the UK, US and much of the world, except where they're lucky enough to get the eight-core version. The eight-core model packs Samsung's own Exynos Octa-core processor, but it's hard to find.
There are more versions of the S4 than you can shake a stick at. There's the wallet-friendly S4 Mini, the waterproof S4 Active, and the the camera-tastic S4 Zoom. There's the regular S4 and the eight-core S4. And now there's not one but two LTE-A versions too. Hit play to find out which one is best for you:
LTE-Advanced connects to the Internet at nearly twice the rate of today's 4G LTE phones. Technically LTE-Advanced is in fact true 4G, whereas the networks currently marketed as 4G are more like 3.5G or thereabouts. The world's first LTE-Advanced network is in Korea, giving phone fans in Seoul test speeds of around 100Mbps.
That kind of dizzying speed is a way off for us, however. EE is the UK's first 4G network, with the other major networks including Vodafone and O2 planning to launch 4G some time this year.
