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.
It's unclear how much of the performance difference comes from software, as the iPad and Nexus One use different web browsers and different JavaScript engines. However, both use modern WebKit engines. The tests also show it being much faster than the iPhone 3GS, which is much more likely to be directly comparable; in most cases, pages loaded in just over half the time on the tablet.
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.
