Anand Shimpi got his hands on one of the new MacBook Airs and ran some preliminary benchmarks:
- Battery capacity has not changed
- The chip Apple is using in the new MacBook Airs is the Core i5-4250U
- The 3D rendering performance of the new CPUs is similar to the performance of the 2012 model, but the 2012 model runs slightly faster on multi threaded tasks
Base 2013 13 inch Cinebench Single Threaded Benchmark = 1.11
Base 2012 13 inch Cinebench Single Threaded Benchmark = 1.11
Base 2013 13 inch Cinebench Multi Threaded Benchmark = 2.46
Base 2012 13 inch Cinebench Multi Threaded Benchmark = 2.65
- The SSDs are substantially faster than the SSDs on the previous model
2013 MacBook Air SSD (Samsung) Peak Sequential Read Performance = 793.831 MB/s
2012 MacBook Air SSD (Samsung) Peak Sequential Read Performance = 407.5 MB/s
2013 MacBook Air SSD (Samsung) Peak Sequential Write Performance = 767.488 MB/s
2012 MacBook Air SSD (Samsung) Peak Sequential Write Performance = 372.6 MB/s
