I think Apple seriously upped the ante with this revision. So far in the few months that the Core 2 Duo MacBook Pro has been available, there have been no widespread reports of serious issues. I am not sure what exactly went wrong with the Core Duo MacBook Pro's quality control, but there were widespread reports of issues, not to mention my own trials and tribulations with four different units. This is Apple's second try with an Intel processor in their flagship notebook and the results are much better. So, how does a 4 cylinder make more horsepower than a V8? Its far more than the number of cylinders, just as its is far more than Ghz for CPUs.Source: version (Muscle cars made much more, but enlarged the engine and got terrible gas mileage) Today, we have 4 cylinder engines that produce 300 HP, and V8s that produce muscle car HP but get economy car fuel mileage. The i Series are built on that philosophy.Īnother way to look at it is this: Most common car (US) V8 engines in the 70s produced as little as 110 HP. This really showed when their mobile CPUs were beating out their desktop CPUs, so Intel switched to their 'mobile architecture' for everything, thus Core and Core Duo. Intel found the adding cores, reducing heat and improving cacheing improved performance more than Ghz. One thing to note is that the transition at Intel from Pentium to Core Duo essentially ended the Ghz wars.

Update: I see some additional questions in the comments about how a 2 Ghz processor can 'beat' a 2.4 Ghz processor.

If you still have a hard drive in your old Mac, the SSD alone will shock you in performance improvements for your Mac. Not only that, but the newer Mac features better graphics (even integrated graphics), built in SSD, etc. The newer i5 machine has a Geekbench score of 3609 vs 1320 for the Late 2008 MacBook Pro 15'. I assume your 2008 MacBook Pro is a 15' model, as the 13' did not ship with that CPU. The i5-6360U is in the Late 2016 13' MacBook Pro and is a Skylake CPU.
