The majority of quad-core parts only have 6MB of 元 and seem to do just fine, so I don't expect that this is too big of a deal. The default chips for both systems comes with 3MB of 元 cache. It's only in the thread heavy stuff that the Pro machines will pull away. This is actually a pretty big deal because it means that for single threaded applications you actually get similar performance to a MacBook Pro. Turbo is fully supported at the default Intel ratios (more on confirming this later). Both can be upgraded to the same 1.8GHz Core i7, a big change from last year's lineup where even the upgraded 11-inch model was slower than the base 13. The 11 comes with a 1.6GHz part by default while the 13 ships with a 1.7GHz chip. There are three different CPUs Apple offers in the new MacBook Air lineup:Īll three parts support Hyper Threading and Quick Sync, although the latter remains mostly unused in OS X. Max power consumption is likely lower on the new MBAs, although typical power consumption could be higher as Sandy Bridge cores are significantly faster than the Core 2s used before. The 17W SNB parts include memory controller and GPU, leaving only the chipset at 3.4W. The previous generation used a 10W part for the 11 and a 17W part for the 13, but remember those figures didn't include NVIDIA's GeForce 320M which is good for at least another 14W under load, and probably a watt or two with the GPU idle. While the previous generation MacBook Air used an NVIDIA chipset with integrated GeForce 320M GPU, Apple is relying entirely on Sandy Bridge's processor graphics this round.Īpple opted for ultra low voltage Sandy Bridge CPUs all with a 17W TDP. The cases are simply too small to accommodate any 32nm quad-core parts.Īlso NVIDIA is completely out of the picture here. Despite being named similarly to the Core i5/i7 in the MacBook Pro, only dual-core Sandy Bridge is offered in the MacBook Air. Like the iMac and MacBook Pro before it, Apple has blessed the MacBook Air with Intel's 32nm Sandy Bridge family of CPUs.
