Thermals: The Leg Test

At the end of my 2010 15-inch MacBook Pro review I mentioned that the bottom of the chassis can get uncomfortably warm. The higher peak power draw of the Core i5/i7 combined with the discrete GPU of the 15-inch MBP can result in more heat dissipated than the previous model.

The 13-inch MacBook Pro is built off a mature yielding 45nm Core 2 Duo CPU. Given how long Intel has been making this CPU it's safe to assume that this chip is running as cool as physically possible. While the mobile Core i5/i7 still have a lot of improving to go through. While the base of the 13-inch MBP can get warm under normal use (aluminum conducts heat very well...towards your lap), it's not as bad as the new 15-inch. I'd say it's pretty much on par with last year's models.

To quantify these differences I pointed an infrared thermometer at the bottom of a few MacBook Pros and reported the surface temperatures. They were taken in a room with an ambient temperature of 76F.

At idle the 13-inch MacBook Pro is about room temperature. The new 15-inch is a few degrees warmer and the 2009 15-inch is actually the warmest. Remember that the Core i7 in the 15-inch has a very low idle power thanks to Intel's power gating.

While browsing the web the temperatures climb up considerably. The new 13-inch is still cooler than anything else, while the new 15-inch model's power efficiency let's it run cooler than the previous model.

Running Half Life 2 Episode 2 changes things dramatically. Now all three machines are running at or above 90F and the 2010 15-inch MacBook Pro is finally warmer than the previous model. If I measure temperature near the exhaust fan on the notebooks the new 15-inch model peaks at 105F compared to 99F for the previous generation and 92F for the 13-inch.

In all cases the new 13-inch MacBook Pro keeps surface temperatures under control. In most situations the 2010 15-inch MBP is actually cooler than the previous generation, it's only when the dGPU is active or under heavy load that the surface temperature can go well above what the older model would do.

    this is slightly off topic, but i wish some of you guys know the answer to this. right now i'm using a mac mini with a logitech mouse, and the movement of the mouse is just terrible. i did some research online and it says it's because of the mouse acceleration is different in macs. my question is, if i were to buy the magic mouse... would the acceleration be any different than me using my logitech mouse right now?

    thanks in advance. again, sorry for diverting.

    I've never noticed a difference between mac or other mouses and I've used mainly logitech mouses on my macs. There are logitech mouse drivers which I've never bothered to install, might help you though. Also try fiddling with system preferences/mouse settings.

    The acceleraiton would be no different, that is an OS related thing. However you may find the Logitech has faster tracking than the Magic Mouse.

    You can get little programs that "fix" OSX's different acceleration curve, one is called MouseFix or something like that.

    Good luck

    I'm very happy with my 2010 13" MBP and just Tuesday upgraded to Seagate's new Momentus XT. Aside from a 20mb/sec average read speed increase over the stock drive, it's caching to flash storage gives a great overall boost to everyday use.

    "For the past 1.5 years every single Mac has shipped with some form of NVIDIA graphics, standard, regardless of price."

    I was just on Apple's website and found iMacs that have Radeon GPUs in them.

    I know this wont mean anything to anyone who already has their mind made up. But I have a ridiculous desktop for running games and any intense windows apps. However I also have a 13" macbook pro that is awesome. It stays charged for a very long time even running a virtual machine (vmware fusion is great) for when i need to do something in windows xp or 7. I have it partitioned with windows 7 which I can either boot into if I really need the extra performance for something or I can load it in vmware to get any files I may need. It has some useful terminal commands built in and the trackpad is hands down the best I have ever used. Using any other laptop feels gimmicky compared to the multitouch and all the stupid hand swipe gestures that surprisingly increase productivity! It does cost more, but it isnt plastic and I really feel that people complain about the glossy screen just to find something to complain about. I would never buy an apple desktop but I feel that the 13" mbp is a great computer.

    If someone could do a review on the laptop that I
    currently suspect is the best "bang for your buck" out
    there. It's made by compal, and available on Cyberpower.com who's
    machines you've reviewed before.
    If you'd like it configured like I did, which I think is the best bang
    for buck, do this:
    Go to the website.
    mouse over 15.6" Laptops and click on the $999 Xplorer X6-8500. It has a 1080p screen.

    (I'm not sure why the people who run this site do this, but even though the other
    configurations use the same chassis when personalized they
    come out to cost more than this one; annoying since it makes me configure all 3
    or 4 machines built on the same base chassis to figure out which one is
    cheapest/best for me.)

    Then I configured
    it with the Core i7-620M CPU. (to get it over 1K so I can take advantage of the 5%
    off.) 4GB 0DDR3-1333, hopefully 7-7-7-21, probably not, but
    hopefully.
    ATI MR HD5650 1GB GDDR3
    320GB 7200rpm HDD (I did this cause I'm gonna take that HDD out
    and use the Seagate Momentus XT 500GB, thanks for that
    review!!)
    Everything else on that page I left untouched.
    The only thing I did on page 2 was switch to Intel wifi with bluetooth;
    Though I'm curious if the MSI option is
    equal/better; 17 bucks isn't nothing.

    It has HDMI out and a fingerprint reader. This page says 3 USB ports,
    the specs sheet says 4USB ports; not sure which is true. (I do wish
    they were USB 3.0 ports, but I was hoping you guys would test some stuff and
    tell me if that even matters for use with an external hard drive, mechanical
    disk 7200rpm. Transferring large files like movies and games mostly.)

    On page 3 I select "none, format only" for
    the OS. And select "LCD perfect assurance" cause even 1 dead pixel is
    unacceptable to me.
    This brings the total to $1008.90 after 5% off, or $992.75 if
    you get the MSI network card.

    So yeah, I really hope you guys can get a hold of one of these
    for review; as a loner or given as a review unit or maybe
    someone will just buy one and review it cause it's really tempting me right now...
    like a lot!
    If you're review is good I'm gonna start
    saving up and hopefully be able to buy it around Christmas. Thanks
    guys! A loyal reader. - Brian

    Have you installed Windows 7 on the new 13" MBP? I'd be curious to know what kind of battery life you get using Win 7.
