Is there any way to tell when the new processors are in turbo mode and shutting a core down and increasing clock frequency?Would be cool if there was a way to force this and see performance differences...

My 2011 macbook pro started shutting off with increasing frequency. It was very frustrating. I installed mavericks and now it seems to shut off about every 5 minutes! Only if I'm working, if it's streaming it seems fine. I think it would be impossible to actually get work done. I've read many others are having the same problem and taking theirs in for costly ineffective repairs.

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)

vs.
Core i3 330m 2.13GHz (~3472)

Core 2 Duo P8800 2.66GHz (~3700)

vs.
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.
I am a bit puzzled about my new MacBook Pro. I got the i5 but I have read online that these are actually dual core processors. What is the difference between the Core 2 Duo and the new i5s then?
Also I have a 27" iMac with i7 Processor, those are quad-core, any difference in processing power besides the clock speed?
I have observed the tech specs on numerous models of MacBook Pro, but it says nothing about 2nd generation processors. I assumed that they did have 2nd gen processors as the image they use to advertise the processor is for the 2nd gen series of Intel core processors. I just wanted to confirm this belief.

I just ordered a Mac Pro with Two 2.8GHz Quad-Core Intel Xeon, 2G of memory, 2 500G hard drives and I am wondering it is possible to upgrade it to 3.2GHz more cost effectively then buying it from apple directly during the purchase of a computer or even post purchase?
Also my unit came with 2 500G HD's, this comp is the lifeline for my webstore, web design and storage for all my personal stuff. So i am wondering if I should just buy 2 more 500G drives for roughly 80-90 a drive(memoryamerica.com) and a Raid Card to back up the first 2 500G drives or just buy a Western Digital 1 or 2 TB external OR buy a 1TB Time capsule.
The sole reason for the external or extra internal drives is in case the first 2 500G drives fail I don't lose any data.
Lastly, I bought the basic ATI Radeon HD 2600 XT 256MB card to run two monitors(one for the webstore, one for web design, photoshop and Adium or anything else I would use on the daily). I plan on putting in as BR drive(i know Leopard does not support it) but I was looking to use it for burning BR movies, and if need be run MV(microsoft Vista) to view/copy and burn BR movies(the two screens I am getting are HDCP), i am afraid this card does not support 1080P BR data, does any one know which one will?
I have talked to a Mac Genius and got no real info do to me wanting to use non Apple components IE non apple supplied HD's, memory(buying a 8G memory kit from Memoryamerica.com to reach 10G of memory) and BR drive and Dell Monitors(more cost effective and supports HDCP/BR)....

View 2 Replies View RelatedI'v just noticed, after installing iStat menus, two different CPU usage measurement graphs. Core 2 duo, so apparently one for each core or chipset, whatever . But the weird thing is, that sometimes, while watching movies, burning dvd etc. (sample "high usage" situation), when the CPU temp. goes around 60 celc. and fan spins at 6200 rpm, one of the "core graphs" shows nothing, like the core is shutting down (screen attached). It's annoying, because the whole system slows down, I can't do anything, and after like 5 mins it gets back to normal (after closing for example the movie). Any solution for this or should I just get used to it?

As this is a feature of the chip I'm assuming this is true for the new Quad core as well. Is it? How can I find out? Any online reviews/overviews/etc. that looks at the new chips?
New mac user, just bought a new MBA -- when should I just close the lid vs shutting it down completely? i.e. is there a general guideline where if you're not going to use it for at least, say, an hour, then shut down but if you are then close the lid, etc. Also let's assume we are talking about the MBA not being plugged in for this scenario but operating off battery.

I'm trying to zero the data on an iBook hard drive before selling it. When I connect it to my Powermac via firewire in Target Disk Mode, it shuts down completely about 30 minutes into the proceedure (and yes, the power adapter is connected).
This has now happened 3 times in a row.
I just got a 8 core Mac Pro at work and it has developed a nasty crashing habit. I think that I have narrowed the problem down, but I wanted to see if anyone had any advice. The machine crashes whenever I view a PowerPoint (08) or Keynote (09) file in presentation mode. In the current setup I have the presentation on one screen and my notes and information on the other screen. I am running dual 24 inch LED monitors (not mirrored) and when I disconnnect one of them, there is no crashing and the presentations work great. I have two NVIDIA GeForce GT 120 512 video cards.
View 2 Replies View RelatedI searched the archives and I can't believe no one has mentioned this yet! This is a huge problem on both my Rev A and my new Rev B. When you connect an external monitor and external speakers using the headphone output, there is a high frequency ringing sound coming out of the speakers. I've managed to live with it by turning the treble to minimum and keeping the volume low enough but at the expense of sound quality. The strange part is, if you disconnect the monitor, the ringing sound stops. The problem only occurs if you have speakers and monitor plugged in at the same time. I've tried this on my Samsung monitor, my SONY TV, and my Panasonic audio receiver. The problem occurs with both Rev A and Rev B while my white MacBook and 2007 MacBook Pro all sound fine.

I'm planning to order + install a OCZ Vertex TURBO (128 Gb) in my new MBP. Unfortunately, as these SSDs are still fairly new, I could not find any information from people who have experience working with them, let alone working with them on a MBP.
Does anyone have one of these, and have you encountered any problems? Or would you not recommend buying one of them, and go for the OCZ Vertex instead (which seems to have a larger user-base).
I have the i7-2620M CPU. How does turbo boost work on my Mac. And what is the max GHz speed for Turbo Boost 2.0 in 2011 MBPs?
View 3 Replies View RelatedI've been using airport express for a year, but lately the airport utility ceased recognising my airport express. No matter what I did, nothing changed.I took it to my friends house, to try it on his mac, and the utility found it and the strangest thing was that my macbook (at my friends house) also found the airport express in the airport utility menu. But when I took it back to my place same thing happened, the utility could not find the wireless device. What could be the causing this? I mean, it worked at my place before and now it doesn't, but it works at my friends house. Could there be something that interferes with the apple airport express frequency?
View 1 Replies View RelatedI 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).
So this past week when my mini hasn't stayed in sleep mode, it shuts itself down about a minute later after being in sleep mode. I haven't changed any of my settings in a year and a half, normally it would stay in sleep mode until i come back to it and logged on again. When it does shut down i just cannot power back on i have to unplug the adapter then replug it in for it to start up again. I've searched google and on here for possible ideas. I wouldn't think it to be overheating since I'm not running any applications when i put it in sleep. It might be the power supply since i have to do that process to get it to work again. Let me know what could be causing this or ways to troubleshoot this problem.
