    Other things being equal, i.e. assuming that the OS/apps can handle multiple cores properly, it depends on the task. In order to benefit from multiple cores/threads the job needs to be sliced-and-diced, the pieces processed separately, then the results reassembled in a meaningful way. For that to be effective the individual elements need to be minimally interdependent. If they're not then it's ineffective to process them separately.



    Multiple cores work well for tasks like 3D rendering or for video processing. Video compression on the other hand also requires continuous analysis of frame-to-frame differences, so subdividing the job isn't as effective.



    That's why when we see benchmark results of multi-core Macs the results can be all over the place, depending on the nature of the particular test. For some people a higher clock speed may be better than more cores, for others not.

    So when can I start seeing this or even quad-core in my regular Macbook Pro?

    But will it run Crysis?

    Mmmmm.... Light Peak. But I think it's too soon. I have nothing to base that on, I just think it is.



    - Jasen.

    Thankfully Intel has been working dilligently to improve multithreading capabilities in not only their CPU but also their development tools with Intel Thread Building Blocks. They've also helped with memory bandwidth with their Quick Path Interconnects



    Apple will continue to push Grand Central Dispatch and my hope is that most developers are onboard with GCD optimized software after 10.7.



    Sandy Bridge is going to bring 8-core per socket so we're going to see 16 core 32 thread CPU in 2011. We'd better have the bus bandwidth and software smarts to keep as many cores fed as possible.



    And Larabee will take over the GPGPU market.

    And it still won't be able to animate smoothly 2 dashboard widgets with a freaking GTX 285. That's some criminally negligent programming at Apple.



    Running OS X on these is such a waste of perfectly good hardware.

    Can you ever really win? If you buy something between refreshes, the new one comes out the next week. If you are an early adopter, you have to deal with a bug or two until updates come out.

    I will probably get one of these. after I wait a bit to make sure there aren't any major problems...

    Heh, woot, woot,

    I'm waiting to replace my (very capable) old dual 2ghz G5.

    Finally, a reason to buy a Mac Pro instead of an iMac i7.

    I can't wait to run Adobe Illustrator on one of these...



    and watch it peg 1 CPU, while 11 sit idle.

    Sorry, I was too lazy to dig up the link earlier. Here it is.



    Not conclusive but certainly interesting reading. And yes, the problem is memory bandwidth.

    I second that. There's nothing like sending a long HD project to Compressor and having to wait 20 hours to two days for all of the rendering to be done. Same with Color.

    If that animates smoothly on the MacBook Pro I have I guess it should do the same on Mac Pro with GTX 285 graphics.
