The pace of rise in mobile phones has been incredible in the last few years. Recently, 1GHz continues to be the norm for processor speed, however in single-core processors.
Now, the next generation of smartphone is arriving, but instead of just boosting clockspeeds further, dual-core CPUs will be the order of the day.
The benefit of going dual-core in these phones is that it offers more capability for multitasking and video, two highlights of mobile phones that have become more prominent.
With smartphones able to replicate much of a PC’s functionality, juggling all that at once needs a good quantity of parallel processing power.
1080p video recording was previously a specialist capability, but it’s arrived on many phones along with the power of dual-core CPUs. It’s not just about having more power in your phone, but about being able to do more with it.
İt is our regularly updated round-up of the current crop of dual-core smartphones, so you can see what each offers and find out which one’s right for you.
1. Samsung Galaxy S2
Release date: Out now
Specs: 1.2GHz dual-core processor, 1GB RAM, 4.3-inch 480 x 800 Super AMOLED Plus touchscreen, 16GB storage, eight-megapixel camera with 1080p video recording
As soon as we saw the Samsung Galaxy S2, it was clear it was going to a phone to watch. Over the next few months, we got more information and the news that the handset would be bumped from 1GHz to 1.2GHz, which promised blistering speed when coupled with the healthy 1GB of RAM. Plenty of on-board storage means accessing the stored apps and media should be lag-free, too.
When we finally got our hands on a review unit, it turned out to be just like fast as we were hoping. The Samsung Exynos system-on-a-chip (which can be replaced by Nvidia Tegra 2 in some regions) never gave us any slowdown problems, and the ARM Mali-400 GPU makes graphically intensive apps such as Google Maps run as smoothly as we’ve ever seen.
2. LG Optimus 2X
Release date: Out now
Specs: 1GHz dual-core processor, 512MB RAM, four-inch 480 x 800 LCD touchscreen, 8GB storage, eight-megapixel camera with 1080p video recording
The LG Optimus 2X has the distinction of being the earth’s first dual-core phone, beating everyone else to market by a slim margin. Powered by a 1GHz Nvidia Tegra 2 system-on-a-chip and sporting 512MB of RAM, it’s got the potential to be fast, though is beaten by the Galaxy S2 both in spec listing and in real use. However, these slightly milder specs (they’re still pretty sharp) have meant that LG is offering the Optimus 2X at an amazing price ? you can pick it up for free for less £25 per month.
In our Optimus 2X review, we found that it was nearly as fast as we’d hoped. Certain parts of LG’s tweaks to Android appeared like the could have used a little more optimisation here and there, however, many apps ran unbelievably fast, and 3D games played extremely smoothly due to Nvidia’s low-power GeForce GPU.
3. HTC Sensation
Release date: 19 May
Specs: 1.2GHz dual-core processor, 768MB RAM, 4.3-inch 540 x 960 qHD Super-LCD touchscreen, 1GB storage, eight-megapixel camera with 1080p video recording
The HTC Sensation is the first dual-core phone from the manufacturer that became synonymous with the best of Android after releasing phones like the HTC Desire and HTC Desire HD. Its 1.2GHz CPU will match the power of the Samsung Galaxy S2, though HTC is using Qualcomm’s MSM 8260 Snapdragon, paired with an Adreno 220 GPU. The excess power of Qualcomm’s parts imply that the newest version of HTC Sense will feature slick 3D elements. The qHD screen nearly matches the Retina display of the iPhone 4 for pixel count, too.
4. Motorola Atrix
Release date: Out now
Specs: 1GHz dual-core processor, 1GB RAM, four-inch 540 x 960 qHD LCD touchscreen, 16GB storage, five-megapixel camera with 720p video recording
There is a lot about the Motorola Atrix that’s similar to its peers. Nvidia’s Tegra 2 system-on-a-chip powers the handset, running at 1GHz, like the LG Optimus 2X; there’s 1GB of RAM, just like the Samsung Galaxy S2; the qHD screen matches that offered by the HTC Sensation. But the specs are only a small part of the story. Where the Atrix stands out is in its innovative Webtop mode, using the power of its dual-core CPU to provide a laptop experience when plugged into a screen with the HDMI cable.
Being a dual-core phone, we were reasonably impressed with the Atrix. Apps loaded extremely quickly, and navigating around Android was snappy. However, the main reason to pick this phone up is surely that desktop capability. You can control it with Bluetooth mouse and keyboard peripherals, or use a laptop dock that the phone slots into. When you are done working at your computer you simply grab your phone and take your desktop with you. Breathtaking.
