| Scoobes said: First benchmarks of the CPU (A6) are in. Twice as fast as the A5 in the iPhone 4. Interestingly though, ever so slightly SLOWER than the CPU in the Galaxy S3 (not by much, but still surprising). http://www.tomshardware.com/news/iPhone-5-Benchmarks-ARMv7-performance-Apple-A6-Chip,17634.html Not quite what I was expecting. |
One possible explanation is that the A6 uses a newer instruction set (ARMv7s), so apps will automatically be faster after a recompile. Javascript benchmarks just came out today and the new iPhone smokes the competition in this area:

Of course this Safari has surely been recompiled already. But it's also worth noting that broadly speaking, if a dual-core and quad-core have the same benchmarks, the dual-core will be faster in real applications due to non-parallelized code.
