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.

The Display: Just as Good TRIM Support On the Way?

    I have a brand new Macbook on my desk here at work, as well as newish (Phenom X3) desktop with Windows 7.

    For a while it's been the case that I don't really care which OS I use for random tasks.

    On balance, I prefer windows simply because I can game when I want to.

    I never have the huge number of problems people seem to run into. Infact, I've had to force the Macbook off by holding down the power button more than once, so neither is perfect.

    Been there, done that.

    After my mother had her laptop crash consistantly when using school scheduling and grading software that the schools tech staff could not fix (many lost days in productivity) I have to say Apple is not necessarily always golden.

    Does that mean that PC is better for this? Not necessarily (as I do not have any direct experience with that. Apple has done a good job flooding the Education segment with their products from almost day one. Hell, I still remember "computer" class on an Apple IIe!!!!!)

    The only frustrating thing I find about the Mac is simply, well, simplicity. One person put it on another post it is the difference between "tone" and a 40 band graphic equalizer. Apple has a good amp, and a simple "tone" knob". PC's have that equalizer. Problem with PC's is that 4 BILLION different companies make those equalizers and YMMV (The Yiddish Equalizer puts Bass on the RHS!!! ;) )

    Anyway, that 1 day thing is a crock. I DO AGREE however, that you need to use BOTH for more than a few minutes to get a feel for them, their OS, their available programs and hardware and how they fit your lifestyle.

    If either stank, they would not be around this long.

    Period.

    Don't blame you guys for wanting some simple and stable to run on. You have what is essentially given as-is to you. You work within its limitation as well, as with all Apple products. So while this type of "closed" product is good for some it's not so great with others.

    Then you have the Windows OS PC side where you should expect issues. That's because just about everyone has a thing for it. If they screw up the PC screws up. But there's great flexibility there and you do have spend time to find the right products; which in itself is a fun thing for some :)

    So other than bashing one of the other, just enjoy how the PC suits your needs currently. And if you need should change, as it usually does, just pray that whatever product you have will allow it :) This to me the the most crucial.

    That's a rather insulting reply.

    In the past I've been professionally employed as a systems engineer, integrating Windows, unix and mainframe (IBM, Fujitsu, etc) systems. I've architected, designed and developed large scale multi-tier transaction processing systems across all these platforms, including middle ware products.

    From there I moved into the R&D of a 3G mobile network, actively architecting, designing and implementing parts of one of the most successful 3G networks currently being operated.

    If this makes me one of the people you consider a "moron" and that Windows is "clearly too taxing on their mental abilities", then so be it.

    Thank you for your considered and polite input to the debate.

    Do any of you remember Anand's first Mac article?

    I do not see how people can even allow themselves to complain. The MacBook Pro 13 features great construction quality (UniBody), has got premium speakers and a premium display, along with the best battery in the business. After all, nearly 10 hours web browsing with that performance behind is an incredible unmatched ratio.

    That it is thin and does not all excessive bulk anywhere (pretty much a flat surface), is to me more important than some ultra-portables weighing a few 100g less. Volume is what matters when you put it into a bag or similar.

    Otherwise everything about it just reeks of quality. I've tried the trackpad and the keyboard, and they both instantly became my favorites among the few notebooks I've tried with chicklet keys.

    Additionally, if you go to college, you can get an iPod Touch, eligible for upgrade to the new iOS4, for free. Considering how the trends state that you get more money in return when selling your Mac, than a PC, I personally consider the price tag a steal.

    I am really not weary to understand the hate against Apple. Sure, they do not support all standards, as they place bets only on the horses they in the future predict will be predominant. An adapter can solve pretty much any video output issue, whereas you have BootCamp in case you need Windows for something. Since let us face it, few among you have heard about people returning from OSX to Windows, as the former is simply superior in terms of user interface. Then what is there left to complain about? That they use dirty tricks in their marketing? I think most businesses do, and Apple has made a clear effort to actually improve their products to become eco-friendly and efficient. So even if their thoughts are somewhere else entirely (money & profit), these changes to apply to changes in reality.

    No complaints from me this time. The review was nicely done with little to no "ohh, woww, OMG" type of personal inputs. That I can live with as I'm actually reading a review rather than having to sort through all the irrelevant, persuasive comments.

    This time, I don't see how some could bash the review hahaha Nice work Anand.

    The PC fanboys seem absolutely threatened by any Mac reviews on this site, its lunacy.

    I myself use and like both Windows PCs and Macs, so whatever

    It seems clear to me that the new 13" MBP is really the best the new lineup can offer.

    While many of my pet peeves remain, such as the glossy display, poor resolution, lack of good connectivity choices etc. the improved graphics performance, battery and bumped minimum specs actually puts it back in the running as an option for a truly portable computer.

    While the lack of a 'modern' CPU is an issue on paper I have to say nothing about the actual performance seems that bad to me.

    Anand,

    I'd like to see an SSD comparison on one of the Mac platforms to understand which drives hold up the best in the non-TRIM aware OX S. There are some benchmarks out there, but none with your rigorous testing methodology.
