Analyst: Graphics war heating up in mobile

SAN JOSE, Calif. – Mobile systems are driving toward better graphics, better voice quality and quad-core processors, according to 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 (Mountain View, Calif.) “I think we will see more game play on smartphones and less on dedicated devices like the Nintendo 3DS and Sony Playstation Vita—even 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.

Addressing the trend, Neil Trevett, head of the Khronos Group, will speak on mobile graphics in a keynote at an annual mobile conference Gwennap is hosting in San Jose in April.

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 200 Hz to 3.6 KHz of telephony to a range spanning 20 Hz to 20 KHz 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.

  • GPU是什么
  • GPU(Graphic Processing Unit,图形处理器)有时也被称为视觉处理单元(VPU),是一个专门应用于3D或2D图形渲染的微处理器
    GPU性能
    GPU可广泛应用于GPU嵌入式系统、移动电话、个人电脑 、工作站和游戏机。GPU在计算机图形处理方面表现优异,其高度并行的结构,使它相较于一般的CUP处理器更善于处理一系列复杂的运算。在个人电脑上,GPU(图形处理器)往往集成于显卡或者主板。
