    I'm looking to update my 15 inch 2.66ghz 2010 MBP, and while i'd like to wait for Skylake, it's time for a new laptop.

    Has anyone with the just updated 15 inch 2.5ghz or 2.8ghz (Mid 2015 ) benchmarked on Geekbench yet.


    Can't find anything for it yet, or reviews:confused: i would have thought someone would have reviewed it by now....

    cheers

    Use the mid-2014 benchmarks, the CPUs are exactly identical.

    I looked at those, as the CPU is the same as the 2014 model

    But wouldn't the new PCI2 M.2 interface for the new SSD change the results?

    Not in Geekbench. But yes, those SSDs have a rocket engine attached to them (which isn't M.2 btw. Apple has its own connector on that thing).

    Geekbench only tests the RAM and CPU. Hard drive and GPU will not affect the results.

    For hard drive benchmarks, use Blackmagic disk speed tests. The hard drive benchmarks will be identical to the PCIe SM951-based SSDs found in the early-2015 13" rMBPs.

    For the GPU, use Cinebench or Unigine.

    Note that Apple does not use PCIe M.2 SSDs. Rather, Apple uses a custom PCIe SSD with a proprietary Apple form factor (which means non M.2). The late-2013 and mid-2014 ones used XP941-based SSDs (for the Samsung ones at least), and SM951-based in the early/mid-2015 ones (apparently Samsung is the sole supplier for the 2015 ones).

    Both of these custom XP941s and SM951s have the same form factor, but the XP941-based is only 2-lane (except the 1TB), while the SM951-based is 4-lane across all capacities.

    No worries, i assumed it would have changed the outcome:eek:

    i just called it M.2 as it is the closest interface that i could relate it to.

    ----------

    thanks for that guys,

    A new 15 inch 2.8ghz is a huge improvement over my older MBP, according to Geekbench, the performance is worth it . 3552 (2015 2.8ghz vs 1800-1900 2010 2.66ghz)

    Cheers

    They aren't the important benchmarks either, 64 bit multicore is the section you want with your 2010 getting 4818 and the 2014 is getting 14690

    You should be looking at 64-bit multicore benchmarks, not single core ones.

    The CPU looks like it is somehow a smidge faster...

    I am pretty sure that both are within a reasonable confidence interval. Every individual benchmark run will be different due to random causes.
