By now, all major tier one publications have published their reviews of the iPad. All reviews seem to be generally positive, but so far none have put the iPad under any serious benchmarks and stress tests.
The iPhone 3GS uses the ARM Cortex A8 CPU while Google's Nexus One uses Qualcomm's very speedy Snapdragon QSD8250 CPU. Both phones are fast by today's standards, but Apple's A4 CPU seems to stack up well against what's available.
"So how does Apple's A4 stack up against today's favorite smartphone brainchild? Extremely well. The A4 is particularly exciting because it combines Snapdragon-like CPU performance with a PowerVR SGX GPU. A much better option than the aging ATI core used in Qualcomm's QSD8x50 series," says Anand.
