Do the new MB Pro's throttle?

Hi,

Kindly check if the new Macbook Pro's throttle their CPU's under loads when plugged in...?

I am considering to buy Macbook Pro 15 with i7 and standard screen ( high res not available in India__ 17 inch model does not come with i7 here)...

 

Are you still looking at using Windows or OS X?

 

i've read about some cases of the i7 throttling over at engadget but most users i read about haven't had this problem till now.

 

If your question is about the throttling, then ya! I will be using Parallels whenever I require 7.

If your question concerns my signature, then yes!I am still considering between OS X and Windows 7. I am bored_so to speak_ after working little extensively on Windows 7 and Linux.So I am considering trying OS X for a change.I just need the CPU power, I don't game that great.(GT 330 M could suffice for my purposes)

Since this would be my first laptop purchase, I want a pleasant long lasting one.Also, we are required to pay around 1000$ more than what you need to pay in US for a given MBP.And 3000$ (for the base model) Apple or 4000 $ Elitebook 8740w or Precision...
Has been a tough and loooonnnnng call...(waiting for 4 months to decide with money in hand)

Wanted some nice advices,... posted few questions in the related threads, but had satisfactory answers...I just dont know why I cant make up my mind clearly on one model... HP / Dell will have to wait a month to be delivered... Apple I can just pick it up... At one point I was even considering VAIO Z...
Hope you understand my situation

 

If it throttles,is there any way we can disable that?

 

From what I've read, the throttling is a safety thing for when the system gets too hot and is used to help the system cool down. I'm sure there must be some kind of controls for windows to override it but I wouldn't recommend it. Hopefully someone will be able to answer your questions properly. Good luck

 

In my experience, no. I have an i7 MBP and in both Windows and OS-X I've never had the system maxed on out temperature to the degree where the CPU is throttling down. I do tend to max out the CPU doing chess processing that pegs it at 100% or so for extended periods of time.

You will probably have to download an app called smcFanControl for OS-X to take manual control of the fans at high load. If you do so, the system will remain at 80C or less under max CPU load in my experience and thus will not throttle. In Windows 7 (which I run under bootcamp) the fans turn on much quicker and the temps are also therefore reasonable under full load.

The only systems I've heard about where throttling is a serious issue are quad core laptops running on Intel's 45nm architecture. This issue kept me from buying a Studio 17 with an i7-720QM a few months ago. I'm very happy with the 15" MBP I have now instead. But it's a real shame you can't upgrade to the hi-res and anti-glare screen; it is by far the best upgrade!

 

Well its Apple's policy here.
If you want a upgraded system,you have to order it for 3400$ (+tax and shipping) from Singapore.whereas in US it is 2400$...

What to do now? Cant buy MBP 17 because of i5, so have to compromise at 1440 x 900 with i7

 

The last generation of MacBooks seemed to throttle like crazy. By last gen I'm referring to the MacBooks with MCP79/9400M GPUs. The problem seems to stem from the fan controller not spinning the fan RPM up fast enough to meet the cooling demand. As a result the system throttles. I went through both a last gen MacBook and MacBook Pro with both of them throttling due to this problem.

At my local Best Buy they still have some last gen MacBooks and MacBook Pros as display models and I was able to recreate the throttling issue with Prime 95 there just yesterday. I have a new 2010 13" MacBook Pro that does not suffer from this issue at all. From what I've been hearing on the forums and the recent Apple scuttle bucket the new 15" and 17" models don't suffer from the issue either. That 17" Pro that throttled over at Engadget seems to be an isolated incident from what I understand. Still though it's something to be wary of...

 

Man, I feel you pain. Have you tried other sources, besides official apple website???
I am in China right now, and there is no official mac reseller, but the ones that do claim to be "official" are not bad...

 

I'm running the Studio 17 in my sig with a 920XM (w/ a 150w Dell PSU) and it passed a Prime95 Maxheat 30 min run with no throttling.

Of course in the process of disassembling the Studio 17 I did use some MX-3 on both the CPU and GPU and cleaned up Dell's terrible compound application. I also enlarged the grill holes for air intake with a dremel.

Runs like a champ and games like a champ with the CPU and GPU running great.

I have a few messages in the Dell forums where even without the intake mods, the 920XM was able to pass a Prime95 Max heat test without throttling. Most of the time it is a terrible compound application job by Dell that is the kiss of death. It looks like they sprayed it on with a fire hose.
