Primate Labs, the creator of Geekbench software, has published one of the first benchmarks of the new MacBook Air. The benchmark measures only processor and memory performance, and compared them with last generation MacBook Air, MacBook Pro 13″ model and iPad. The use of NVIDIA GeForce 320M video card and flash storage in the new MacBook Air is expected to offer significant overall performance improvements, but processor and memory performance gives a different perspective on the positioning of the new MacBook Air.
There are two ways you can look at the new 11-inch MacBook Air; it’s either a much smaller but slower MacBook Pro, or a much faster but larger iPad. The 11-inch MacBook Air is small enough that I’d consider bringing it instead of an iPad, but I’d worry it’s not fast enough (or have enough screen space) to be my primary laptop.
The 13-inch MacBook Air is a much more straightforward produc; it has 80% of the processor performance of the latest 13-inch Pro, making it an acceptable substitute for users looking for a slightly more portable Pro.
