the epicentre of debates on whether benchmark scores can actually relate to real- world performance. Snapdragon processors are known to be better at multimedia related SIMD processes even though these score lower at benchmark tests. Snapdragon’s hardware acceleration of Adobe Flash and WEBGL content delivers a smooth Web experience without the freezing or jerking seen if you have tasks running in the background.
This SOC also utilises a Harvard Superscalar architecture. It comes with embedded processor (supporting GSM, GPRS, EDGE, UMTS/WCDMA, HSDPA 7.2Mbps, HSUPA 5.76Mbps, HSPA+ 28Mbps/11mbps, MBMS baseband), embedded seventhgeneration gpsone GPS module and gpsonextra Assistance.
Apple A5 800MHZ
Designed by Apple and manufactured by Samsung using a 45nm process, this is the latest ARM processor from Apple featured in its iphone 4S and ipad 2 devices. A5 is a chip based upon the dual-core ARM CortexA9 Mpcore CPU with NEON SIMD accelerator and a dual-core Powervr SGX543MP2 GPU clocked at 200 MHZ. Apple lists the A5 to be clocked at 1 GHZ on the ipad 2’s technical specifications page, though it can dynamically adjust its frequency to economise on battery life. The SOC also contains 512 MB of DDR2 memory clocked at 533 MHZ.
This chip includes an image signal processor unit that does advanced image post-processing such as face detection, white balance and automatic image stabilisation. Apple remains the only company to have a Powervr SGX543 graphics solution on its SOC. This solution makes the A5 chip a lot more expensive than the rest.
TI OMAP4460 1.2GHZ
OMAP 4460 features dual-core ARM Cortex-a9 Mpcore built using a 45nm process just like the Apple A5. One difference is that this OMAP is clocked much higher (1.2GHZ) than the A5 ( 800MHZ). TI’S datasheet specifies that OMAP 4460 can handle up to 1.5 GHZ but it’s clocked at 1.2 GHZ to keep battery consumption within limits. The GPU featured here is the Powervr SGX540, which helps in 2D and 3D graphics acceleration.
This SOC also features TI’S Smartflex technology that reduces power consumption by dynamically controlling the voltage, frequency and power based on the device activity, modes of operation and temperature. It can handle 1080p HD video as well as 1080p stereoscopic 3D video.
