Yes, thats how small the Quad-Core processors are. So why choose quad-core processors ? Well, because the name is a bit catchy. No seriously, Quad-Core processors provide a higher computing power at a lower battery consumption rate. Now since most of you know Android has battery problems (unless of course you use extended battery packs) this becomes an essential element in improving the phone’s battery life and increasing performance of the device.
Now to solve one of the greater myths about the Quad-Core processors. Quadrupling cores DO NOT increase performance by 4 times the original. The increase in performance is considerable but not 4 times. Quad-Core processors are an essential component in mobile multi-tasking or multi-threading. They provide a significantly smoother performance as well as enable a wider range of tasks to be carried out simultaneously. A single core CPU runs at higher speeds (clocking speeds) than a multi-core CPU but consumes more energy than the multi-core CPU. Now for Multi-Core CPU, since there’s more than one each CPU can run at lower frequencies and complete tasks at a lower energy rate and at the same time ensure that multi-tasking is efficiently carried out.
Mobile devices who have Quad-Core SMP (Symmetric Multiprocessing) have the ability to run desktop-style browsing processes. The ability to utilize multi-cores for the faster web page loading times is possible with a Quad-Core SMP processor. (Usually all Quad-Core processors in the market are SMP enabled)
High Performance is a necessary condition in today’s mobiling world and with the growing innovation in applications on Android the stress on processors continues to grow. The quad-core devices now use their quad-core enabled processor to aid in the working of applications that involve photo-editing, video-transcoding, web-browsing and multi-threaded gaming.
For Example, 3D Panorama is a mobile application that takes panorama pictures and stiches together the images to form one continuous panoramic image. The heavy image processing involved for detecting edges and stitching together images is greatly enhanced and speeded up by the Quad-Core processor.
Top 3 Quad-Core Processors in the market at the moment
1. NVIDIA Tegra 3 Processor
NVIDIA Tegra 3 previously known as the Kal-El integrates quad core ARM architecture processors which is a 32 bit reduced instruction set computer (RISC), central processing unit, 12 core GeForce Graphics Processing Unit, Northbridge and Southbridge support and memory controller in one single package. (For Le Man’s this is AMAZING).
Tegra 3 provides the power for 4 ARM Cortex A9 processors which is the first of its kind. The Cortex A9 is a very powerful processor by itself. The Tegra 3 runs at a 1.4 GHz frequency and each core can be selected individually. This aids in decreased power consumption. There is also a FIFTH core within the processor which runs at a maximum of 500 Mhz. Tegra 3 also supports NVidia 3D and Stereoscopic 3D which will enable the users to play games on 3D.
What others have to say:
“The Eee Pad Transformer Prime is a category-defining product. Powered by Tegra 3, it launches us into a new era of mobile computing, in which quad-core performance and super energy-efficiency provide capabilities never available before. With Transformer Prime, ASUS has once again led the industry into the next generation.”
– Jen-Hsun Huang, President and Chief Executive Officer, NVIDIA
“Tegra 3 is a marvel. Its quad-core CPU, 12-core GeForce GPU and vSMP technology are revolutionary. We worked closely with NVIDIA to build the ultimate tablet — the Eee Pad Transformer Prime — that delivers a magical, uncompromised experience to consumers.”
– Jerry Shen, CEO at ASUS
2. ARM Cortex A15 Quadcore CPU
ARM have their first Quad-Core processor just raring. It runs at 2 GHz without killing the power efficiency of the its dual-core sibling. Manufacturers will get the same power usage as earlier Cortex-A9 chips and faster turnaround times for their SoCs, since they won’t be able to fiddle with them the same power efficiencies will be maintained on every device.
