Many think the more cores a CPU has, the better it is, and this maximalism makes manufacturer power their handsets with more and more powerful processors. Today we are already talking about eight-core (or octo-core) smartphones like the ZTE Apache, but as you can guess, the more cores a smartphone sports the more expensive it is. So quad-core processors can be found on high-end devices only, while dual-core processors have become a standard. But this doesn’t mean quad-cores are better than dual-cores, and neither does it mean that quad-core processors will be available only for those who are ready to pay more.
According to Cens, MediaTek is going to break Qualcomm’s monopoly in Sony’s supply chain. This manufacturer is known for its chips made for low-cost handsets, but if Sony decides to use its quad-core chips in its upcoming smartphones, everything can change, otherwise, we’ll not hear about MediaTek anymore.
Those chips were made by using the 28nm manufacturing process and Cortex A7 processor cores. This means they can be clocked at 1.2 GHz, support LPDDR2 RAM, 720 x 1280 resolution displays, and a 13MP camera with 1080P video recording. Such chips will cost much cheaper, and they’ll make Sony’s smartphones much more affordable.
However, as I’ve said above, quad-core chips are not faster than dual-core ones. Especially this refers to the dual-core ARM Cortex-A15 found on Google’s new Chromebook. Moreover, the iPhone 5’s A6 uses the same architecture. It’s based on Samsung’s Exynos 5 Dual, which is clocked at 1.7 GHz and boasts a 12.8 GB/s memory bandwidth. Now it turns out this chip is way faster than Nvidia’s quad-core Tegra 3 and at least two different Intel Atom models (the N270 and the Z530). The tests showed the Exynos 5 Dual can easily beat those three chips, while when it comes to the 2.13 GHz Core i3-330M, we see a real difference between them.
So quad-core processors are not as productive as they can seem at first sight, and of course they can appear in Sony’s affordable devices.
