Mobile is now all about graphics

Mobile systems are driving toward better graphics, better voice quality and quad-core processors, according to a veteran market watcher.

Graphics seems to be key area of investment, as mobile systems become the game platform of choice," said Linley Gwennap of the Linley Group. "I think we will see more game play on smartphones and less on dedicated devices like the Nintendo 3DS and Sony Playstation Vitaeven tablets are taking away from game consoles," he said.

Nvidia is trying to get console game titles ported to its Tegra3 chip as Apple courts developers to port games to the new iPad that packs twice the graphics capabilities of its previous model. Separately, Qualcomm recently launched its Snapdragon S4 Pro, mainly focused on enhanced graphics, he noted.

"The amount of silicon devoted to the GPU is starting to increase significantly as we look at die photos of mobile chips, he said.

Separately, mobile networks and handsets are gearing up for increases in voice quality through support of improved audio codecs, Gwennap said. "We see a business model where carriers implement higher quality voice for a fee," he said.

Tensilica and Qualcomm are already offering such capabilities in silicon. Some of the work involves expanding support for broader audio frequency ranges from the traditional 200Hz to 3.6kHz of telephony to a range spanning 20Hz to 20kHz in the future, he said.

"People using Skype on a PC already get those good voice experiences, but once you go back to a mobile phone it sounds like tin cans and a string," he said.

A slow move to quad core processors is the other major mobile trend in the works. Nvidia is there with its Tegra 3, Huawei announced a similar chip in February and Freescale is set to ship one later this year.

"I think it's clear with the right software quad core is a better solution [but] most Android apps don't take advantage of quad cores, and Apple hasn't pushed the iOS infrastructure for more than two cores yet," he said.

"Most of today's mobile software is not really going to use three and four cores, but that will evolve over time and things will become more favorable for quad core over the year," he added.
