Quadcore vs. Octocore Smartphone Processors - What's the Difference?
There's been a recent trend of using Octacore processors in smartphones, particularly in premium smartphones such as the Samsung Galaxy S6 and the HTC One M9. However there are plenty of high-end smartphones which feature a quad-core processor including the iPhone 6 and 6 Plus and the Sony Xperia Z3. Does it make much of a difference to the performance of your smartphone?
A Quadcore processor comes with four cores and an Octacore processor features eight cores (although you probably know that already.) Up until this year, the most cores you would expect to see in a smartphone was four but smartphones with Octacore processors seem to be all the rage in 2015. It's worth mentioning though that an Octacore processor isn't necessarily twice as good as a Quadcore processor. The key to a smartphone's efficiency and performance is actually down to how the processor is set up.
A Quadcore processor will have four individual cores which each power a specific area of a smartphone such as the camera, gaming functions and basic tasks including calls, texts and emails. An Octacore processor is actually made up of 2 separate Quadcore processors with each one powering certain functions within a smartphone.
Usually a handset with an Octacore processor has one Quadcore processor which is more powerful than the other and the more powerful chip is used for more advanced smartphone tasks such as recording video and gaming. Meanwhile the lower powered chip is responsible for more basic functions such as sending messages and emails and internet browsing. One of the advantages of having an Octacore processor is that thanks to the lower powered chip taking care of the majority of the running of your smartphone, it's a more efficient way of preserving and extending battery life.
As we know the quest to improve battery life is an ongoing one for most smartphone manufacturers so it looks like Octacore processors will be here to stay.
