Which processor is better?

which processor is better?

A used mid 2010 Intel Core i7 2.8 GHz Processor (2 cores,still under applecare til oct)

Or an Apple refurbished jued 2012 2.5 GHz Dual-core Intel Core i5 processor (Turbo Boost up to 3.1GHz)

Does the 2010 not have a turbo boost? What does the turbo boost do? I am looking for a mac to succesfully run Omnisphere which requires a 2.4 ghz processor. And it is for live music performance.

The newer one is better, even though the clock speed might be higher on the old one, the performance isn't as good as in the newer one.

Turbo boost means that for at shorter period of time, the clock speed of the cpu can boost too a higher speed.

If the minimum requirements are a dual core with 2.4 I would consider a CPU with a higher speed than 2.5 GHz. But if it's only 2.4 single core requirements, you should be more than good with either one. Even though I would buy the newer

The 2012 is significantly better. Just look at the bench marks:

It is not possible to compare processor speed by simply looking at ghz UNLESS it is the same generation - the 2012 and 2010 are not the same generation. If it is several years newer it is, generally not always, almost certainly faster.

2012 CPU is ~10% faster.

You basically compare the i7 640M with the i5 3210M.
Check the list here with various benchmarks.

They rank right next to each other and are for most stuff equal. The 3210M though has some newer features like Quick Sync which is very useful for HD streaming acceleration (meaning taking your screen content and encoding it on the fly into h264 for broadcast over the network or to the web).
Both have Turbo boost but the clock speed difference is negated by quite a bit better IPC (Instructions per clock).

So would the new i5 2.5 ghz MacBook run Omnisphere better than the 2.8ghz 2010 MacBook? The min requirement is 2.4ghz. I don't think screen size will matter all that much to me. I use an external display for studio stuff and when live I prolly won't use the screen all tht much because ill have midi controllers.

Yes, the new one would be faster. You can only really compare ghz to ghz within the same generation. Newer processors are faster per ghz.

I also wouldn't take the '2.4ghz' as a hard guideline because of that. For example a 2012 15" with the 2.3Ghz quad core CPU would be even faster than the 2012" 13" 2.5ghz dual core if your application supports multiple cores.
