So I'm standing by to instantly buy the new MBP now that I have gotten C-suite approval and financing for this IT upgrade (read: my wife said OK
) and as an inveterate Mac rumors follower, I have a pretty good handle on what we expect.
We are all but certain that there will be a top-end dual-core option (2620M). But there is a chance that there will be a quad-core option (2720QM). The differences are really only in the core count and clock speed. So here's my question:
Does the turbo capacity of the 2720QM allow it to perform equally well compared to the 2620M despite the difference in base clock speeds (2.2GHz vs. 2.7GHz respectively) across all tasks? I ask because there was a relatively well-developed discussion regarding the better performance of the 3.33GHz 6-core Mac Pro compared to lower-clock-speed 8- and 12-core models on tasks that were not easily distributed across cores.
I understand that for some processor-intensive tasks that can be broken up across cores (video encoding, which I do, albeit rarely) the quad-core will always outperform. Rather, I'm wondering to what extent the turbo boost feature will allow the quad-core processors to scale performance up to match a high-clocked dual core on tasks in which (in the past) the higher-clocked dual core would have outperformed.
Thx!
(I guess the thread title should be "Understanding turbo boost." Honestly, I'm a bit embarrassed to even post this thread -- I always kind of thought I had a handle on the hardware side of things! Oh, well....)
