Intel is about to launch its range of ultra low-power processor (ULV) of the Sandy Bridge generation. They would be perfect for the MacBook Air: they are also saving its Core 2 Duo, while being more efficient. The Core 2 Duo SU9400 MacBook Air 11 “, with two cores clocked at 1.4 GHz, 10W TDP offers, its graphics chip, the Geforce 320M, it consumes up to 12W.
The Core i7 2657M looming meanwhile has two physical cores clocked at 1.6 GHz, four logical cores with Hyper Threading. It also has a Turbo Boost to enable it to reach 2.7 GHz on a single heart. He finally has a memory bus at 1333 MHz against 800 MHz for the Core 2 Duo. The gain in performance should be just as huge as the MacBook Pro 2011, without this being at the expense of consumption.
Its TDP is 17W indeed: it’s more than the Core 2 Duo, but we must not forget that the Core i7 also has a component 2657M integrated graphics, Intel HD 3000 Graphics. It equips the MacBook Pro delivers graphics performance and honorable, profile (great for video decoding, using for games) is perfect for the MacBook Air. Apple would go well with a solution to a single chip consuming 17W against a two-chip solution using 20 to 22W. What make room for a controller Thunderbolt.
The Core i7 2657M should be available in the second quarter: Apple may well introduce new MacBook Air before the summer. The i5 2537 m, the only other modern catalog ULV chip from Intel could then fit the model 11 “(1.4 GHz, 2.3 GHz Turbo Boost, Hyper Threading, Intel HD Graphics, 17W).
