  50. 50. What to Expect in 2012 ?The Answer is “Quad-Core Phones” o One of the big mobile buzzwords of 2011 was “Dual-Core”. o Dual-Core processors became the standard for high-end smartphones, starting with the LG Optimus 2X . o In 2012, however, it is all about quad-core. o But other than having double the cores of this year’s smart phones, what do quad-cores mean for the smart phones of 2012?
  51. 51. The State of Multicore Processorso Nvidia : • Was the first to bring dual-core processing to mobile with the LG Optimus 2X, which debuted at the beginning of 2011 with the Tegra 2 chip. • Is blazing the multicore trail again with the release of the Asus Eee Pad Transformer Prime TF201 tablet which is also the first device with 1.3 GHz Tegra 3 quad cores .  For now, it’s the only quad-core device on the market.  The Transformer earned high praise for its stunning graphics and zippy performance. • Future : It has said that Nvidia is working with a number of device makers on Tegra 3-powered phones, but can’t reveal who they are due to nondisclosure agreements. Quad-core phones are “on track”, however, for 2012. • The rumored HTC Edge will supposedly be the world’s first quad-core smartphone, running the Tegra 3 chip. Mobile news site “PocketNow” was first to claims to have exclusive images as well as a spec sheet.
  52. 52. The State of Multicore Processorso Qualcomm : • Stated that its quad-core Snapdragon chip, the APQ064, will join its S4 line of products. • Based on ARM architecture, the S4 chips will run at clock speeds upto 2.5GHz. • Qualcomm’s Vice President of Product Management Raj Talluri, confirmed that the first phones with quad-core Snapdragon chips will ship in 2012.o TI (Texas Instruments ): Raj Talluri • Unlike Nvidia and Qualcomm, chipset manufacturer TI isn’t putting a number on its OMAP processor. Rather than calling them dual- core or quad-core, TI refers to them as “Multicore”. • Latest system-on-a-chip is the OMAP 5 by TI. • The company didn’t give any exact benchmarks, but maintains that the OMAP 5 produces speeds competitive with Nvidia’s quad-core processor.
  53. 53. The State of Multicore Processorso Samsung: • Its phones and tablets have used both Snapdragon and Tegra chipsets, but the manufacturer’s semiconductor division is hard at work on the next generation of its own Exynos line of systems-on- a-chip. • The next one, the Exynos 5250, isn’t quad-core, however; it is a dual-core ARM Cortex-A15 processor. • Like TI, Samsung seems to be confident that the Exynos 5250 can produce benchmarks and performance competitive with a quad- core processor.
  54. 54. The More the Cores, the Better?o According to Nvidia : • quad-core processors improve performance during multitasking as well as the performance of multithreaded applications. • quad-core processor will bring to your phone a level of performance comparable to that of a desktop computer. • Nick Stam (Director of technical marketing at Nvidia) : “People are going to consider their phones as their primary computer” “Phones with a quad-core processor are really full computers that can replace many functions of laptops or desktop computers. It is a level of performance that truly does rival a desktop processor.”o According to Qualcomm : • It expects users will see the power of quad-core in the multitasking speed. The speed in which you switch between open applications will be much faster than that of a dual-core phone. • Gaming, of course, is the popular example. Quad-core processors support multithreaded applications, meaning an app that runs multiple processes at once, like a game. Therefore, Gameplay on a phone that can support these simultaneous processes is much more fluid and snappier with higher-quality graphics. • Imaging softwares can stitch together multiple photos much faster than a single or dual- core phone.
  55. 55. Battery Life: What’s at Stake?o 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.o But Nvidia says that quad-core processors are actually easier on battery life than single or dual-core chips.o With the Tegra 3 : • The processes are distributed across the multiple cores, and therefore a quad-core phone consumes less power than a dual-core phone. • 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.o Qualcomm’s quad-core chips will be able to run simultaneously at different clock frequencies and at different voltages.

  59. 59. What is a GPU?• A Graphics Processing Unit is a co- processor that takes on graphical calculations and transformations so that the main CPU does not have to be burdened by them.• The use of a GPU can greatly increase the performance of a device, especially when used for tasks such as 3D gaming.• A GPU can be a stand-alone chip or, as is more often the case, integrated into a complete chip design that includes one or more CPU cores.

  73. 73. • Usually slower than PowerVR SGX Series 5.• But in several Game Scenarios it is found that GeForce GPU is 25-50% faster than PowerVR series 5.• Hardware accelerated Adobe Flash:-NVIDIA worked closely with Adobe to offload the Flash processing from the CPU core and do nearly all the rendering on the GPU core.• This reduces the amount of power consumed and greatly increases the overall performance because the CPU is freed up to handle other tasks.• In the popular Flash benchmark GUIMark2, NVIDIA found that hardware accelerated Flash improved performance 2x to 3x over competing devices that use the CPU to process Flash content.
