    Mac Mini I7-3720QM versus i5 4570 ?

    How much more powerful is the desktop i5 4570 for video encoding and general processing?

    Thanks

    Mobile processors are always slower than their desktop equivalents. The gap is being closed in but it's not there yet. The 4570 will be much much faster than the mobile processor on the mac mini.

    Still amazes me how people spill this bullcrap without even looking at the specs. You're completely wrong.

    i5: http://www.cpubenchmark.net/cpu.php?cpu=Intel+Core+i5-4570+@+3.20GHz

    i7 mobile: http://www.cpubenchmark.net/cpu.php?cpu=Intel+Core+i7-3720QM+@+2.60GHz&id=895

    Truth is, the i7 mobile is faster. I've experienced this as well, with an i7 15" MBP outperforming a 21.5" i5 iMac w/32GB RAM in Logic 9 (the iMac's CPU kept getting maxed out, whilst the MBP handled it like a dream).

    The i7, although it's mobile, is a quad-core processor with hyper threading (8 virtual cores). The i5s are native quad-core without any virtual threads.

    My advice: if you want the best performance, get a desktop i7 processor (i.e.: an i7 CPU in an iMac). Hope this helps. :)

    You are right. For whatever reason I thought the i5 was an i7 and had hyper threading. No reason to be an a&&hole

    Sorry, I thought you were in the camp of 'desktop CPUs are always quicker'. I've seen it loads on MR where people recommend buying an iMac over a 15" MBP just because the iMac has a desktop processor, and frankly it's misinforming people so I'm a little short tempered whenever I read that stuff.

    Apologies for the misunderstanding, my bad. :eek:

    No worries. I am like that when it comes to people saying they can build cheaper better hardware than the new Mac Pro. I pretty much explode.
