    Hey all, i'm currently doing some video editing on a 2012 mac mini 2.6 core i5 and have found a 2008 mac pro with a quad core 2.8 and half decent gfx card.

    Do you guys think this will be a big jump in horsepower for me as I read that the newer i5's are better?

    Many thanks

    Passmark benchmarks put the E5462 (2008 Mac Pro) at about 30% more performance then the 3210M (2012 Mini).

    The i5 can ramp up to 3.1Ghz, but that's only when it's doing 1 thread, but when using both cores it will only go up to maybe 2.7-2.8Ghz. So it is more efficient of a core, but the E5462 has 2 more physical cores. So it can make up through brute force.

    Which brings me on to Hyper-Threading. Hyper-Threading will allow the i5 to handle 2 threads per core, which will make it appear as a quad core to the operating system. But you have to understand what Hyper-Threading is doing. It allows the core to inject a 2nd thread into the core to use "wasted" clock cycles. So for instance if Thread 1 goes in and only requires 60% of the CPU to do its thing, another thread can be injected to use the unused 40%. So for light CPU usage, it's a fantastic technology.

    But with HT when you load up the core with a thread, it will still accept a 2nd thread but there will be very little idle cpu cycles to go towards the 2nd thread. So the single core becomes a more traditional single core performance wise. That's where a true quad core will beat a Hyper-Threaded Dual Core.

    Thank you so much for this, I think I might pull the trigger on this mac pro then. As i'm doing video editing etc I can always buy a bigger and better gfx card as and when? :)

    The Mac Pro 2008 will consume 155 W idle so it may not be cost effective in the long run. Maybe save up for a more recent Mac Pro? 2010 or 2012?

    Don't know much about 08's and new cards off the top of my head mind. RAM is quite expensive.

    Would have thought a decent spec > 3 Ghz i5 would be much faster than an 08 Pro which uses Core 2 tech.

    Also remember to factor in cooling costs due to the thermal output of a Mac Pro vs. a Mini.

    So i've taken the plunge and got it in a great deal on eBay :) I've got a couple of SSDs to go in her. I've one quick question though?

    It's coming with a ati radeon hd 4870? Can anyone recommend a gfx card upgrade for me as i'll be doing some FCP stuff with her.

    Thanks again everyone :)

    If it's a 2008 Mac Pro Quad Core, there is actually an open socket on the logic board ready for another processor and heatsink. The upgrade costs about $70 if you can get a good deal. Search the forum for guides to do so, it almost doubles your multicore horsepower.
