MacBook Air :: Looking For Reliable Notebook (CPU Usage And Core Shutdown)

May 27, 2008

It's the last question before I buy the MBA. I have a program that can run under Win or MAC. That's a Picture convert and compile program work with my project. This program needs 100% CPU to and last 15 minutes to work under my old Pemtium M 1.6Ghz notebook. Usually I do my job use my notebook in home or my desktop PC in office. But occasionally I need to do some compile outside the office.

So I really need to know whether the MBA will definitely shutdown one core when the CPU usage is 100% and last 15 minutes? Or maybe you can tell me if the MBA will shutdown when rendering a project in Mayar or 3D Max last 15 minutes. It's important to me before I buy the MBA. I just need a light notebook and I can do some hard job occasionally, but reliable. I like a Fujisu S6510 too, but it is too expensive and heaver than MBA.

MacBook Air :: When Is Core Shutdown Ok?

Jun 25, 2008

I have a MBA, and I do notice, more often than I had expected, that I'm experiencing core shutdown. I do agree with a previous post that it could, at least partially, be related to the video card/driver. If I decide to run a YouTube video while having Outlook open in VMWare Fusion, I'll usually shutdown a core. Other combinations of applications can do it too, but this combo is almost guaranteed.

My question is: Is there a time where core shutdown is good, for example, to preserve the integrity of the hardware? I don't want to go into the Genius bar complaining if all they're going to say is "Well look what you're running! Of course it'll shutdown!"

MacBook Air :: Getting Core Shutdown - Any Way To Confirm?

Jun 21, 2008

I think I am getting the well publicized core shutdown with my MBA but I can't be sure. I will be doing a task and things like expose will be as smooth as can be but then all of a sudden it slows to a complete halt, everything lags, expose is jerky, cmd+tab takes ages to switch application and keystrokes such as typing take seconds to appear. For a good 5+ mins the computer becomes totally useless. Is this what a core shutdown does to the computer? Is there an application I can use to monitor how many cores are running? I looked in the activity monitor but couldn't find information about how many cores are running. I have used smc control to monitor my cpu temp and I sometimes turn the exhaust up to max rpm before I watch a video or do something that has been causing the core shutdown (if thats what it is) in an attempt to try and keep the cpu cooler.

I have read about coolbook but I don't fancy paying for an application to stop a fault that shouldn't be happening. Are Apple fixing these faults? Is this a problem with ALL MacBook Airs? I ask this because there seem to be two groups of people. People that don't experience this (or say they don't, maybe don't want to admit a fault with there new shiny toy?) and people who have had 3-4 machines all with the same problem. I would love to know if this is indeed a core shutdown fault and if Apple replace it for me as it is becoming increasingly frustrating and not acceptable for a $1200 computer. Would also like to hear from people that have had the core shutdown fault fixed or replaced from Apple and if it has fixed the problem, or if it still exists.

Mac Pro :: Future Of Software Development - Multiple Core Usage

Sep 21, 2010

I am on the verge of buying my first Mac Pro and have a few questions to those with some insight into the software development world before I make my decision on whether to buy a 1cpu or 2cpu MP.I am buying this computer to last me for many years and because of that wondering alittle about the future of software:-)1) Are software developers in general shifting towards making programs that utilize multiple cores? Will games, business software, leasure software etc. slowly start to be made with multiple cores in mind? Or is the trend that multiple core usage is mostly for professional editing?

IMac :: Core I7 CPU Usage When Machine Completely Idle

Nov 21, 2009

For those of you with a new i7 iMac, if your machine is completely idle, what does your CPU usage look like in Activity Monitor? I'm routinely seeing Finder consume 70-90% of my CPU. The single CPU bar meter view in the dock is basically pegged most of the time. The graph shows it as system usage. If I open the CPU History window, all 8 threads look like they're just about maxed out.

MacBook Pro :: Differences Between Core 2 Duo / Core I5 And Core I7?

Dec 4, 2010

I see the numbers of everything from Core 2 Duo, to the slightly faster and cooler Core i3, to the supposedly faster core i5s and i7s. The benchmarks go up accordingly, but I found this does not always equate in a faster experience on most tasks.

Here's my experience so far on processor upgrade:

In one computer trade school re-certification class I am in, we are working with Windows Server 2003 on a Quad Xeon platform and it's incredibly slow.

But in a previous class we had the previous generation server edition on older Xeons, and while not fast, it was much better. On paper the newer multi-core Xeons should have made a difference, but could 2003 server software be that much more bloated than the previous Windows server edition that it would stall like that and make us wish we had the older setup?

I am going to try out the Adobe CS lab and put the new high end Dells to the test there and see if they work better than when we had an older CS version on older Xeon equipped Dells.

I don't know if this is something to do with Dell, or if Apple's increasing processor bumps/generations are going to similarly not make a difference in the speed things appear to go at, whether it's Adobe stuff, server stuff, or anything else that needs power.

I know somebody who plans on a Core 2 Duo, i5 or i7 MBP and I was wondering if the higher end processor is worth it in that case (iMovie being the main program of use).

MacBook Pro :: 13" MBPs - Core 2 Duo Versus Core I3 Processors

Apr 18, 2010

There's a lot of people wondering if the 13" MBPs would have been a lot better with a Core i3 processor, but everything has been just hangups over perceived old vs. new technology, and really the only thing the Core i3 adds is Hyper-Threading, but it doesn't have Turbo Boost, which helps the Core i5/i7s tremendously. Let's compare using Geekbench since it is cross-platform and one of the few available sources of info...

Core 2 Duo P8600 2.4GHz (~3362)



Core i3 330m 2.13GHz (~3472)


Core 2 Duo P8800 2.66GHz (~3700)



Core i3 350m 2.26GHz (~3680)


As you can see in both cases, the difference is pretty minimal indeed, and in single threaded applications, the C2D will easily outdo the Core i3 which lacks Turbo Boost and runs at lower clock rates.

And you get a 320M instead of Intel HD graphics with the new 13".

The Geekbench results from the old 15/17" to the new 15/17" are quite an order of magnitude better.

So unless people are expecting Core i5 processors in the 13", sticking to the C2D was actually a good decision, and given the differences between 2.4 and 2.53 isn't so large, one is far better buying the base 13" and then putting the money saved towards a good 7.2k HDD or SSD.

Note - I took averages of the 32-bit numbers and added them.

Note 2 - The C2D Pxxxx are 25W TDP processors, which are more efficient than the Core i3 which are 35W TDP processors. Less heat, better battery life from C2Ds.

MacBook Pro :: 13" 2.4 Core 2 Duo Versus 2.2 Core 2 Duo Santa Rosa

Apr 29, 2010

I've been debating whether or not to upgrade my 3 year old 15" Macbook Pro that has a 2.2Ghz Core 2 Duo (Santa Rosa) to the new 13" 2.4Ghz Macbook Pro. FYI... My current system also has 4GB of RAM. Since both systems are Core 2 Duo, what kind of speed bump am I going to see? Would this be a substantial upgrade?

MacBook Pro :: Quad Core Versus Dual Core?

Jan 8, 2011

Just in case Apple surprise us with a Sandybridge Quad core, and even if they don't I was wondering the following.

1 ) During sustained use in 3D gaming does a Quadcore with lower clock speeds beat a dual core with higher clock speeds.

2) Can the quoted turbo speeds be achieved in sustained use (ie 3D gaming where maximal load can be applied for a couple of hours).

MacBook :: Is There Reliable Pre-paid 3G Usb Modems Out There

Feb 21, 2009

They'll pay most of that for the time being BUT in this economy and speeds getting faster almost every year, I'd be stuck with it. MOST I'd want to go is a year(carrier doesn't matter we get $50/mo. but goes to a person not a business) in case there's any changes in staff and being stuck paying it or having a 5 G or something a year in and pay to break it off.Basically it's to show off to clients how ads work at our company and how they can see there's other clients of ours have work for them that they can submit bids on. Usage is very light. Not a replacement for my broadband only on the road type of things. Questions:1. Is there reliable pre-paid 3G usb modems out there?2. Is there a cheaper way of doing this say, change out my sim card to the device from my Iphone? We're all ATT I know first gen (what I have) iphone allows me to use a crappy older cell when I go to the beach or anywhere it's too bulky or easier to break.

MacBook Pro :: Which SSD Is Most Reliable For Boot Camp

Jun 6, 2010

I'm a long time user of PCs but have just bought my first Mac - a new 2010 MacBook Pro 13". I want to replace the hard drive with an SSD, however looking through the threads on this forum have got me worried. The Intel ones seem to have issues with Boot Camp (I want to install Windows 7 x64 on it as well as OSX) and the OCZ Vertex forums have horror stories of Macbooks not booting at all off the SSD (albeit on the 2009 Macbooks).

Is there any SSD that has proven just to work? Ideally it should have garbage collection as well and be 120-160GB but that is my only stipulation.

MacBook Pro :: 15" Core I5 Versus Core I7

Although i'm hardly impressed by the prices and specs of these 'new' machines I need one so I'm buying!

Just need to know before I make the plunge. Is the i7 variant with the extra GPU ram really worth it? I would use the extra power in my work but I honestly need to know if I'd notice any difference as for a few seconds less waiting it would hardly justify the price.

MacBook Pro :: Finding Notebook With Hexacore-CPU?

I dont call this for good, but it shows what is possible and that others work an Core i7-980X laptop while we get only C2D chips.

6 vs. 2 Cores for equal prices (sure not egual quality and it's very ugly) and Apple is still cool and thinks we are all happy with our mac's.

If this six core could run OSX, I would think about it. But I still hope for a 17"MBP with 4 cores.
