On October 20, 2010, Apple CEO was Steve Jobs the newly upgraded MacBook Air models with 11.6 inch and 13.3 inch screens. The new MacBooks's that have been achieved slimmer easier but, at a price. These laptops have no high processing capacity. If you want to do some performance improvements over hardware upgrade. 11.6 Inch MacBook comes with two variations-1.4 GHz Intel Core 2 Duo processor with 3 MB on-chip shared L2 cache or 1.6 GHz Intel Core 2 Duo processor with 3 MB shared L2 cache. Both processors have 800 MHz front side bus. The machine comes with 2 GB 1066 MHz DDR3 SDRAM, the onboard memory that can be upgraded to 4 GB. AnandTech revealed that the 1.6 GHz processor coupled with 4 GB RAM significantly increases the machine performance at the expense of seven percent "battery endurance." Here is the performance graph of various Apple laptops based on Adobe Photoshop CS4.
Now compared to the $999-configuration (11 "MacBook Air 1.40 GHz processor with 64 GB SSD"), this upgrade would cost $1399 (1.6 GHz Intel Core 2 Duo processor, 4 GB of RAM and 128 GB SSD) but it's worth the additional performance from your lean machine would receive. I'm not a technology expert, but I think that there is another fact behind this performance. Although Apple uses old processor, MacBook Air models have a powerful NVIDIA GeForce 320 M graphics processor. The iLife suite has HD Photo and video editing capability and the MacBook Air runs iLife11. So, this GPU plays an important role in promoting MacBook Air's performance.
