That is virtually useless as most people will not be doing video processing on an 11" computer.
Core i7-620UM 18W does 2111, 4004 on Cinebench single and multi
Core 2 Duo 2.13ghz 17W does 2054, 3281 on Cinebench single and multi
The i series chips only have a very modest (less than 10%) improvement over the Core 2 chips integer wise. That is clock for clock if you are lucky. i Series has seen improvements to the floating point unit and vast improvement to vector or SIMD capabilities. The question you have to ask your self is so? Really when looking at an ultra thing small laptop is this sort of performance what is important to most users? How many AIR users use the device for this sort of work and how many are inclined to use an even smaller machine for this sort of work.
If the Core i7 18W Arrandales' Intel GPU could do enough of what Mac OS X and iLife applications require, these might be a possibility in the 11.6" MacBook Air.
I would be extremely surprised to see any i series chip in such an AIR. To many compromises and to much power. Most importantly where is the OpenCL support. That one little feature is key to the future of Mac OS/X, without support for OpenCL Apple would be forced to run everything through the i86 cpus.
This one little issue, OpenCL, is why I think AMD's Zacate Fusion product has a chance on this platform. Yeah the CPU performance isn't outstanding but the big concern is over all capability and long battery life.
Apple would also be saving space since they wouldn't have to allocate space for the Nvidia 320M.
True but then they have to live with crappy Intel video!
Based on Solipsism's Intel links below, even the most expensive Core i7 18W CPU is the same price as the 2.13GHZ Core 2 Duo 17W.
I doubt Apple pays those prices. When buying by the hundreds of thousands you do get discounts.
Interesting... The only question is how will the Intel GPU in the Core i7 18W series do under OS X tasks.
Interesting? Come on man we already know the answer to that one.
Does anyone know how often the Intel graphics switch to the discreet graphics in the MacBook Pro 15"? Say, when rendering iMovie or editing adjustments to photos in iPhoto?
Depends upon your software. Besides Apples goal was to make that switching transparent so you have to go out of your way to know. In any event you don't want Mac OS/X to be held back by Intel Integrated GPU technology when alternatives are available.
Also consider this, what does the performance look like with that i7 18 watt CPU when running single threaded or modestly threaded software that doesn't afford itself GPU acceleration? In a way they are suckering you in with references to Cinebench which matches up well with the i series architecture. Instead look for benchmarks that cover more common software on such a platform.
