2012 2,9 GHz Intel Core i7 vs. 2015 2.7Ghz Intel Core i5

[aimee2020]

Hi all,

so here's the dilemma.

I want to buy a new 13'' macbook pro but am not ready to switch to the new ones with the usb3 (to many worries about connectivity and high prices) that I am considering a 2nd hand of 2015.

I now own a 2012 2,9 GHz Intel Core i7 with 500 SSD
I am looking at 2015 2.7Ghz Intel Core i5 with 256 SSD

What is driving me nuts is the Intel Core. It looks like my older is quicker (it's a i7 with 2.9 instead if i5 with 2.7), is this really possibile even though it's 3 years older and what I bought back than was kind of a standard model?

I would really not want to buy this and see that it is slower than the one I have now.

Any suggestions?

Thanks!

You need to consider the IPC (instruction per cycle) which is how much work gets done per cycle.

Broadwell as higher IPC than Ivy Bridge

Check geekbench scores

Thanks, where do I find IPC info?
So you mean Broadwell is better than Ivy Bridge right?

HERE is where you find the information:
https://browser.geekbench.com/mac-benchmarks

Here is the results:

MacBook Pro (15-inch Mid 2012)
Intel Core i7-3820QM @ 2.7 GHz (4 cores)
12005


MacBook Pro (13-inch Retina Early 2015)
Intel Core i5-5257U @ 2.7 GHz (2 cores)
6745

From those results the higher number on the multicore is better. So the 2015 computer is substantially slower.

My vote is buy the best new computer with the highest specs you can afford and stay with it as long as you can. That's what I do.

Mmm that's not what I found.
I found:

MacBook Pro (13-inch Mid 2012) (what I have now)

Intel Core i7-3520M @ 2.9 GHz (2 cores)

3372

MacBook Pro (13-inch Retina Early 2015) (what I want to buy)

Intel Core i5-5257U @ 2.7 GHz (2 cores)

3546

So the scores you have above are the benchmark scores per core, the totals that @jlseattle listed are the combined scores of all cores together but that was comparing a four core model to a two core model processor.

To sum it up, based on processor speeds only, newer MacBook Pro with 2 cores will be faster than your current model.

I do want to add to notes:
1) If your current laptop has a standard HDD hard drive then you will also see a boost in total speed since the 2015 model uses an SSD hard drive.
2) Also, I'd check the amount of RAM you have; the 2015 model came stock with 8gb RAM and if you have less than that on your current machine that will also make the newer one faster.
