Quad-core processors: Do they really double up the efficiency of smartphones? – Part 1

As the numbers rise, so does the processor technology. Last year we saw dual-core processors dominate the game of smartphones and tablets. The year before, HTC brought the first Android smartphone with a processor clocked at GHz of speed, the original EVO 3G.

However, the technology has evolved and I must say that the process has been quite fast as the dual-core processors are now the thing of the past. The new quad-core processing units designed by technological company called ARM have been incorporated by NVIDIA. However, the latter one has managed to introduce the processor first in the market.

The processors succeed the predecessors the same manner car models do on the yearly or biyearly basis. The A8 single-core chip was replaced by A9 dual-core.

Differentiation comes two ways. ARM designs different chip models with different architectures — like the A8, A9, and A15 chips — each more capable than its predecessor. As a starting point, says Samsung’s Nick DiCarlo, you have to compare the architecture of each chip when comparing SoCs. A single-core A9 chip (also called Cortex-A9) will dominate a single-core A8 chip, and so on.

Though more processors are considered more efficient, experts have a different view to this expression. ARM designs the processors but how are they incorporated into the chip is the art of companies like NVIDIA and Qualcomm.
