iPad processor blows away Nexus One
The A4 processor in the iPad is far faster than the Qualcomm Snapdragon processor running the Nexus One, according to early benchmarks. Although both run at 1GHz, Apple's chip is usually at least 9 percent faster loading most websites; it's up to 60 percent faster with very visually intensive websites. The AnandTech tests noted some unusual spikes, but even discarding these is an average of 10 percent faster.
The design is believed to still be based on the ARM Cortex-A8 architecture and has the chief advantages of a larger enclosure and battery that let it run at the higher speeds. However, it's not known how much if at all Apple will need to scale down the clock speed to accommodate it in the next iPhone, as no one has checked the power consumption of the A4 independently of its other components.
Apple will face stiffer competition after a 1.3GHz Snapdragon appears, but it's unlikely to ship in finished phones until late this year.
