- JnOrris, on 10/12/2007, -2/+34do you guys understand that you are bitching over 1%.... how about this: the C2D Macbook Pro runs cooler.... there its settled.
- pOwErBoOkEr, on 10/12/2007, -6/+38Note that the headline was corrected to read "Core 2 Duo MacBook Pro runs 40 degrees (F) cooler." Fahrenheit is not an absolute scale, so percents are meaningless.
- M4v3rIC, on 10/12/2007, -5/+27Holy *****. Get over it, just read the article.
- Hindu_Wardrobe, on 10/12/2007, -9/+26Even better: "Steve Jobs takes a MASSIVE *****!!! With PICTURES!"
...hell, I'd have to digg that - noseeme, on 10/12/2007, -1/+18I'll have his last MacBook Pro if he doesn't want it. :|
- elastikos, on 10/12/2007, -15/+31Bloody hell, what's next for a Digg headline: "Apple changes a pixel in iTunes 7.0.4 - ***** Yeah!!!"
- JeremyBanks, on 10/12/2007, -1/+15Who uses Farenheit in general? It's essentially arbitrary!
- vagarach, on 10/12/2007, -3/+14...by a tiny amount. 6 or 7%, who cares!!!! When I need to use my laptop on my lap, I use centrino hardware control and set the clock to 600Mhz. And then it doesn't even get warm.
- reiggin, on 10/12/2007, -6/+17::: Even better: "Steve Jobs takes a MASSIVE *****!!! With PICTURES!" :::
Woz posts (another) bitter rebuttal: "Steve Jobs never flushed a toilet in his life! I was the man behind the scenes! I wiped every ass at Apple... I AM A TP GOD!" - cvrefugee, on 10/12/2007, -2/+11Who uses Fahrenheit when it comes to CPU temps? I've always seen (and used) Celsius.
- reiggin, on 10/12/2007, -7/+15This guy has two MacBook Pros? I don't care at what temp they operate... I hope his balls get fried.
- lilrabbit129, on 10/12/2007, -1/+9I'm sick of all the people that b*tch about how they got screwed cause their 5 month old computer isn't top-dog anymore. 5 months is an eternity when it comes to computers, plus unlike usual, everyone knew that Core2Duos were coming out and that they would replace the Core Duos in the (then) current MacBook Pros.
If you got a Core Duo MBP, enjoy it. Want to feel slow? I'm still on my 867mhz G4. - anonym41414, on 10/12/2007, -3/+10Your arithmetic is totally fracked.
The article says that a Core Duo MBP ran at 162°F. It says that the new Core 2 Duo one runs at 122°F. Room temperature is approximately 70°F; that's the temperature a MBP would be if it were off. So the Core Duo had a temperature increase of 92°F while the Core 2 Duo had an increase of 52°F.
That's 43%. Not 25%, and sure as hell not 6%. - Ireland, on 10/12/2007, -1/+7Just to clarify for all Europeans:
122ºF = 50ºCelcius
115ºF = 46.1ºC
117ºF = 47.2ºC
That's actually pretty cool with regards to the current generation of laptops, and I'm quite surprised. This whole "very hot" thing diluted my interest in buying any of the new Apple laptops, but that may change if these reports turn out to be the norm for these new MacBook Pro's. - thebiscuit, on 10/12/2007, -2/+8About -137'C if you're going by the Kelvin scale - 274'K is O'C so half of that is 137K, 137C
- rolf, on 10/12/2007, -1/+7Next to the article "Toyota just screwed all the customers who bought 2006 models 6 months ago by releasing 2007 models."
Shame on you Apple! - bparker, on 10/12/2007, -3/+8You got 2 macbooks? ... Can I have some money?
- anonym41414, on 10/12/2007, -1/+5Hee hee. Yeah, I'm sure he was using his laptop outside in a blinding snowstorm when he ran the test.
- foolfromhell, on 10/12/2007, -1/+5Oh, and a second MBP too! I wish I had his money!
- idiotwithastick, on 10/12/2007, -3/+6Who the hell cares about absolute scale anyways... if it runs 50% cooler absolute you'd be screwed... the numbers will all be under 10%.
And this guy didn't mention noise level at all... 30 dB of noise for 40 degrees (F) cooler might not be worth it... - cbegin, on 10/12/2007, -4/+7It could be due to the lack of a 7200 RPM hard drive option....
(7200 - 5400) / 7200 == 0.25
LOL - foolfromhell, on 10/12/2007, -1/+3Lucky bastard..... 2.33GHz MBP!
- umdigger, on 10/12/2007, -0/+2Got my MBP on Tuesday and I must say, compared to my PBG4 it is amazingly cooler. My powerbook pretty much had the fan running constantly, so it is quieter as well.
I did put a 7200rpm drive in my G4 though, so I'm sure that makes it a bit warmer. - QueenOfSwords, on 10/12/2007, -1/+2I've heard that the fans run faster by default in the new MBPs.... which is something current MBP owners can experience by running smcfancontrol or similar.
- grant1080, on 10/12/2007, -2/+3That's great, too bad I bought my MBP for school in September
- rolf, on 10/12/2007, -1/+2The fans in the first Mac Book Pro didn't come on often or fast enough. The heat was such an issue that there is a popular app out there that let owners control the fans themselves (Fan control 1.1). The article mentions this and that the fans come on more often this time around, so apple probably fixed that issue in this release of their premium notebooks.
IIRC, the first Mac Books can get similiar temperatures with that fan control applet. - pkghost, on 10/12/2007, -1/+2if that's how you feel, digg them down and move on with your life.
- Ireland, on 10/12/2007, -2/+3Actually guys, he said the old CoreDuo MacBook Pro's ran up to 162ºF, which works out at 72ºC. And the new one runs up to 122ºF, which is 50ºC, that's 22ºC cooler, not 6! That's a huge reduction in heat which nobody could argue with.
- rickcarson, on 10/12/2007, -2/+2Dude. Here's a clue. If you have to say zing... then you didn't zing them.
- thatbox, on 10/12/2007, -1/+1headband, that sounds about right from my four days of experience with my own new MBP. I watched a 720p x264 movie last night and it stayed around 50-57C. Idle seems to be around 45-48C, but I haven't tested temperatures under load, yet, although while running 3DMark 06 the fans ramped up to very noisy levels and the back bottom of the machine got -almost- too hot to touch.
- macbookpromat, on 10/12/2007, -2/+2I don't think these numbers are right. He must be comparing the first gen MacBook Pro that had all the bugs, because mine runs real cool for a laptop.
- mschuermann, on 10/12/2007, -1/+1This is very true. My new Core2Duo Macbook Pro was noticeably cooler just by perception. Honestly, for some general use, you actually CAN put this thing on your lap! It still warms up a bit when using intense tasks, but trust me, it's NOTHING compared to the Core Duo models.
- kodek, on 10/12/2007, -5/+5If it's 0c degs, and they say tomorrow will be twice as cold, what temperature will be tomorrow?
- marix, on 10/12/2007, -3/+3This just in! its now winter and its typically cooler than it was the last time he checked temps.
- ivc-, on 10/12/2007, -1/+1Database: http://www.intelmactemp.com
- galatians, on 10/12/2007, -1/+1My core 2 duo temperature fluctuates rapidly depending on usage but idles at 33 'C which is much cooler than my old P4 latop's 48 'C.
- FHKE, on 10/12/2007, -4/+4The Americans.
- wankey, on 10/12/2007, -1/+1yeah Core 2 duos are the next gen architechture. Core duos were the Yonahs.
- geminitojanus, on 10/12/2007, -1/+1You also have to understand that TDP does NOT equate to the actual amount of power put out of these chips. The Core 2 architecture is generally more efficient all around (effectively, a singular core without its L2 cache is only 20-25 million transistors tops [some estimation math for you: the Core 2 w/ 4MB L2= 291M transistors, w/ 2MB L2=167M transistors; 291-167 = 124M transistors per 2MB L2. 167 - 124 = 43M transistors per 2 cores without L2; /2= 21.5M transistors per core, which is still inaccurate due to it including the transistor count for the smart cache controller/2, and for the on-chip core-to-core APIC and L1-to-L1 connection. It's feasible that they could fit a single Core 2 chip without L2 in under 20M transistors), which is TINY, barely bigger than some Pentium 3's without caches [it's roughly twice the size of the original P3, however, which makes perfect since because it's a 64-bit processor with 64-bit code pathways requiring twice the transistors]), and with its more complex gating and lower voltage levels it could put out less heat for most operating scenarios and put out more in others (thus averaging out to the same TDP, but using less power; this is also the reason for the increased battery life in the Core 2 models).
- hakro807, on 10/12/2007, -1/+0Which is quite pointless to mention since a CD/C2D consume _much_ less energy than a P4.
- elpayo, on 10/12/2007, -1/+1My Core 2 Duo MBP is also far cooler - looks like Intel's done an excellent job of cranking more power out of a cooler running chip.
- cptcomic, on 10/12/2007, -1/+0"if it runs 50% cooler absolute"
I wonder if some of you guys realize that percentage is a relative term? - bangmalley, on 08/30/2008, -2/+1so, who actually done good job here? Apple or Intel? or someone else?
- Morky, on 10/12/2007, -1/+0Intel on the processor. Apple on the design and the perfectly executed platform migration.
- headband, on 10/12/2007, -6/+5I agree
DL.TV yesterday they said the new one runs at 70C under load instead of 90C
guess what...my e1705 with a t2500 runs at 45C under load
yeah apple sure has some amazing engineers - akashra, on 10/12/2007, -2/+1I'm a little confused. The TDP of both chips is almost identical, and the process is the same. So where does the wasted heat/efficiency come from - that's a huge number when you consider they've added a few million transistors and that it consumes the same amount of power etc...
- TylerDurden0, on 10/12/2007, -2/+1Oh yes, very nice...
- cptcomic, on 10/12/2007, -3/+0"Who uses Farenheit in general? It's essentially arbitrary!"
Which scale is not? - mastercheif, on 10/12/2007, -5/+1Mac people are new to this whole CPU Temp thing, they usually don't have to worry about it.
- usernameistaken, on 10/12/2007, -9/+4The whole upgrade of the Digg algorithm to prevent pointless stories from reaching the front page... it still needs some work.
