Is there any reason to be excited about the new CPUs? I'd say that the high-res display on 15" and better battery life are more interesting.
Also, any info if the graphic cards switch automagically or you have to log out?
- Anon84 17y agoAccording to the website you shouldn't even notice the switch: www.apple.com/macbookpro/performance.html

- jrockway 17y agoIn my experience, the i7 is ungodly fast. A linux recompile is about 20 seconds on my box. Unfortunately, it's the i5 that has crypto acceleration. The i7 does about 80MB/s/core, and the i5 does something like 2000MB/s. But is slower otherwise. Fucking Intel....
- petercooper 17y agoI can't speak for the mobile models but on the desktop, i5 vs i7 is a wash for most tasks with only a few percent in it.
- Anon84 17y agoHow so?
- petercooper 17y agoToms Hardware did a reasonable roundup: http://www.tomshardware.com/reviews/intel-core-i5,2410.html http://www.tomshardware.com/reviews/intel-core-i5,2410.html On the media apps, the i5 beats the equivalently clocked i7 on most of the benches. On the productivity section, the i5 is equal to the i7 on 2 of the 5, and beaten by 10-20% on the others (those that seem to feed heavily on the hyperthreading and extra cache of the i7). Notably, though, the i5 and i7 are a wash in the Photoshop test (a key benchmark for the sort of things I do).
- borism 17y agowhat crypto acceleration does i5 have?
- arete 17y agoActually the latest mobile i5 and i7 are both Arrandale variants and support the AES New Instructions: Core i5 2.53GHz: http://ark.intel.com/Product.aspx?id=43544 http://ark.intel.com/Product.aspx?id=43544 Core i7 2.66GHz: http://ark.intel.com/Product.aspx?id=43560 http://ark.intel.com/Product.aspx?id=43560 I think the only real difference is clock speed and that the i7 has an extra megabyte of cache.
