Apple releases MacBook Air SMC Firmware Update 1.2

New high-end MacBook Air is slower than the previous one

In yet another of its reviews new Apple computers, the Macworld tested the new MacBooks Air, launched at the opening of WWDC ’09. Although the new top-of-the-line model is equipped with a 2.13GHz Intel Core 2 Duo processor and a 128GB SSD, appearing to be faster than the previous model, tests carried out by the magazine's editorial staff confirmed a slight drop in performance in relation to the machine equipped with a 1.86GHz processor.

At the Speedmark, benchmark used internally by staff at Macworld, the new ultraportable scored a total of 175 points, while its correspondent from the previous generation reached 179 points. Of the 18 tests done by the Speedmark, the new machine only managed to be faster in seven, as reported by Jason Snell, editor responsible for the analysis.

Although the new top-of-the-line model is not slower than the basic one overall, Snell reports that certain operations may run faster on the newer cheaper MacBook Air, which costs $ 1,500 and also comes with a 1.86GHz processor, in addition to a 120GB SATA HDD. Video compression and 3D rendering are some areas highlighted by the journalist in this regard.

The most accepted hypothesis is that the advanced configuration is being hampered by its thermal envelope, which apparently has not changed much from one generation to another. Even so, the components must be assembled in a way that does not compromise its energy efficiency or raise the average temperature of the machine, which may be making it match the lower configurations, when it does not slow it down.
