Windows Phone 8 could have dual-core chips but not use them

Qualcomm has revealed that dual-core chips have been approved for Windows Phone 8, but that they may not be used.

Windows Phones could go dual-core in the not too distant future. Qualcomm has revealed that its dual-core chips have been approved for Windows Phone 8.

Microsoft's Windows Phone software currently runs on a range of phones from assorted manufacturers, most notably Nokia, but they're all single-core. Chip-builder Qualcomm has suggested that will change when it's updated to the next big version of the software, Windows Phone 8.

Speaking at Taiwan trade show Computex, a Qualcomm boss told CNET Asia the company's Snapdragon S4 chip has been certified for Windows Phone 8.

Intriguingly he also said that even if a dual-core processor is put into a new Windows Phone, it didn't mean that "both cores would be used". I wonder what that means, as it doesn't make much sense to put an expensive processor in a phone and then fail to use it to its full capability.

Perhaps this is a reference to the way multi-core phones only fire up backup cores when they're taking on a tough task, leaving the day-to-day chores to one core. High-end phones such as the quad-core HTC One X and Samsung Galaxy S3, for example, only turn to the extra cores when taking on heavy work like playing fast-moving games or videos.

But the existence of quad-core phones just shows how far Windows Phone is behind other types of mobile. The iPhone 4S is dual-core, and so are many Android phones -- making single-core increasingly look like the budget option.

But that's not to say multi-core is universally popular. Simply chucking in extra cores isn't automatically going to make a phone as powerful as it could be: processor and software must work in perfect harmony too. And some think multi-core is a waste of juice -- Nokia reckons quad-core phones just waste your battery , while Sony sneers at quad-core inefficiency .
