".. The main advantage of dual core cpus is, that they actually use less power, generate less heat, all while outperforming single core cpus. A single core cpu has to run at max voltage and still wouldn't outperform a dual core cpu that is running at a significantly lower clock speed and using a lot less power doing so..."
"..ARM Cortex A9 - This is the chip that's going to dominate 2011. Most of the 2011's most advanced smartphones (including the iPhone 5) will likely feature a dual core version of the Cortex A9. In that configuration, it's more than twice as powerful as the Cortex A8 while consuming less power and generating less heat..."
"..But we wont just see faster load times and better rendering, well also experience less processor and battery heat and longer battery life from our smartphones. Here are additional benefits to dual-core processing:
Faster Web page load times
Lower power consumption and higher performance per watt
Higher quality game play experience for advanced console-style mobile game
Highly responsive and smoother UIs (user interfaces)
??Faster multitasking
Technology has been moving at a ridiculously fast pace, and one area of tech weve been hoping to see catch up is battery technology. As our gadgets do more and consumer more power, batteries seem to be improving at a snails pace. So far, getting the most out of the battery has been up to good user management and optimized software, but with dual-core processors we could see a pretty dramatic change in battery life..."
Das müsste reichen
