In 2012, however, it will be all about quad-core. But other than having double the cores of this year’s smartphones, what exactly is a “quad-core” processor, and what do quad-cores mean for the smartphones of 2012?

In 2012, however, it will be all about quad-core. But other than having double the cores Nvidia was the first to bring dual-core processing of this year’s smartphones, what exactly is a “quad- to mobile with the LG Optimus 2X, which debu- core” processor, and what do quad-cores mean for ted at the beginning of this year with the Tegra the smartphones of 2012? 2 chip.

Quad-core phones are “on track,” however, for 2012s first quarter. Of course, that doesn’t stop the blogosphere from speculating.

It is a level of performance that truly does rival a desktop processor.” Qualcomm’s Talluri expects users will see the power of quad-core in the multitasking speed.

The Tegra 3 chips actually have a fifth “companion core” that is built using a special lower-power-silicon process. This companion core handles tasks at a lower frequency for active standby mode, music playback, and video playback. Qualcomm’s Talluri explains that Qualcomm’s quad- core chips will be able to run simultaneously at dif- ferent clock frequencies and at different voltages. For example, say you open an e-mail (which requires little power) and then click on a link that opens a Flash-based website with video (which requires significantly more power). The system will smartly Games aren’t the only applications that can real- adapt its cores to handle the different power levels. ly benefit from a quad-core processor, however. Imaging software, such as a panoramic app, can I predict that we’ll see more quad-core tablets at stitch together multiple photos much faster than a CES in January, and that the first quad-core phones single- or dual-core phone. Photo and video apps, (likely from Nvidia) will appear the following month like Adobe’s Photoshop Touch for tablets, also benefit at Mobile World Congress. But right now, it is still from the extra horsepower. too early to predict the impact of quad-core phones on the mobile world. One of the arguments against quad-core mobile devices — and really, even dual-core devices — is Related Articles: that not enough content is optimized to fully take advantage of the CPU’s power. Both Nvidia andhttp://blog.batteryfast.co.uk/quad-core-smartphones-what-to-suppose-in-2012/ Qualcomm assured me that they are actively wor- king with developers to optimize content for their chips. But in reality, we won’t see a boom of these fully optimized applications until actual quad-core products ship. Battery Life: What’s at Stake? Shortened battery life is the thorn in the side of smartphone innovation. Smartphone batteries can’t seem to hold up as processors get more powerful and networks become faster. But Nvidia says that quad-core processors are ac- tually easier on battery life than single- or dual-core chips. With the Tegra 3, the processes are distributed across the multiple cores, and therefore a quad-core Love this PDF? Add it to your Reading List! 4 joliprint.com/mag Page 3
