How much more powerful is this processor

2.5GHz Intel Core i5-2400S, quad core with 4 threads (used in the baseline 21.5" 2011 iMac) vs 2.0GHz Intel Core i7-4750HQ, quad core with 8 threads (used in the baseline late-2013 15" rMBP: http://browser.primatelabs.com/geekbench3/compare/352255?baseline=523255
The 2.0GHz i7 is significantly faster, because:
1. i5s only have a maximum of 4 threads, so hyper threading isn't supported.
2. The Haswell chip in the rMBP supports newer instructions and has double the number of threads.
In simple terms:
The 2.5 i5 is like a four-lane highway, where everyone is driving at 25mph.
The 2.0 i7 is like a double-decker four-lane highway, where everyone is driving at 20mph but there are *twice as many people*.

Depends which Sandy and Haswell you compare. But sticking to MacBook Pros: Haswell i7-4750HQ and Sandy Bridge i7-2860QM the difference is pretty small.

Number 36 and 42 on the list.
I know both are i7
But you should compare processors which are similar in application. Both were in Macbook Pros.
Maybe specify what procs are you talking about exactly?
The 2400S is a processor with lower TDP. I mean lowe then a standard 2400 cpu.
To stick with metaphors:
The i7-4750HQ and i7-2860QM are big tracks full of load. Delivering stuff in one big slow package.
The 2400S is a small truck, speedy, and it uses much less gasoline. And is not destroying roads delivering stuff (is not heating whole computer)
It all depends what you need?

The OP was comparing between a Sandy Bridge 2.5GHz quad core i5, so there would be a massive difference with the Haswell 2.0GHz quad core i7.
Between the Sandy Bridge 2.5GHz quad core i7 and the Haswell quad core i7, the difference wouldn't be much.
agree
i just don't see the point of making such comparison. And it makes an illusion of overall big difference between Sandy bridge and Haswell cpus, when in real life it's not that big (if you compare the same grade of cpus)
