No, actually the MBA should be slightly faster. It has a better memory controller and everything. And benchmarks I have seen appear to reflect this (MBA getting slightly better memory scores than the rMBP despite lower CPU performance).
I haven't heard or seen that. The rMBP has twice the processor speed 8gb of ram. Its a totally different animal.
Is the new MBA MUCH faster than an early 08 MBP? Since the 08 MBP has the gpu... Thanks.
Twice the processor speed?? The 13" base model has the i5-3210M CPU which is maybe 15% faster then the MBA's i5-4250U. And the Haswell CPU is a new architecture with an improved memory controller.
P.S. I am obviously not talking about the 15" rMBP here.
true so if the processor in the macpro's were 1.3ghz then the haswell would be faster.
I have no idea what you are talking about. The fact is, Haswell is faster then Ivy Bridge (the previous fastest architecture) clock-by-clock. Go and look at the benchmarks before you post nonsense.
P.S. And yes, it makes sense to use a slower clocked, cooler running CPU if the performance is sufficient. Or do you insist on going for groceries in a racing car? If you need performance, pick a higher-clocked model, it will outperform any other CPU.
