I used to have an Apple application that sat in the menu bar. It gave you the option to select how many processors/cores you wanted to utilize. You could turn off the others.
Does anyone know what's it called and where to find it?
I have seen some images posted of the cores being monitored to show their usage but I don't know what people use to see this activity. Are there any free apps that you can install on the Mac Pro to monitor usage of the cores?

I hear Mixed Reviews on the New Nehalem 2.26 GHz Mac Pro Octo. I have also come to believe that 8 Cores Benefit Video More Than Audio, the diagnosis being that 8 Cores Is Overkill for audio. Is Pro Tools A Multi-Threaded App. And What Mac Pro Would Be Best For Audio?

View 1 Replies View RelatedI hear people saying stuff like " to bad that 8 cores wont be used" Or " 8 cores can actually be slower and 2 cores"
How is that?
Wouldn't a 8 core 2.8ghz be faster than the 4 core 2.8ghz in the mac pro?
What would the 8 core be good for? Or doing what puts those 8 cores to use?
And finally is the 8 cores worth getting?
People that use lightroom, can you look at your CPU usage for all 4/8 cores and tell me what the usage is when your importing/searching/doing whatever and if there is any point in me getting 8 instead of 4 cores (Save myself �300 and get 8gb ram vs 4Gb!)
System will be on 300Gb Velociraptor and data on a 1TB Samsung F1, so lets say IO won't be that bottlenecked.
What kind of PPD can we expect?
Hopefully some of you guys will puts its power to the MaCrumors Folding effort!
Any specific window to access on the Air to see if one core has shut down?
View 6 Replies View RelatedHi, I have a question to Owner of the New Mac Pro Nehalem (4 Cores):
How many CPU you see in After Effects CS4?
Which would be faster and why?
Two 3.0GHz Dual-Core Intel Xeon processors
One 2.93GHz Quad-Core Intel Xeon
I have the option to buy the first one (used) for $1,900 OR buy the 2nd one brand new from for $2,999
Which, if any, of the video editors make use of all eight cores of the Mac Pro? I haven't tried the pro apps yet, but CPU utilization for iMovieHD was only about 200% on the one project I have done on my new 2.8 Octo. It seems like this would be widely-known information, but I was unable to find it on Apple's site, and my extensive search of this forum was unavailing.

Also is the 8800 GT worth getting over the 2600 XT. and can one have two 8800's (or is that too much power draw). I am assuming you can have one of each (1x 8800 + 1x 2600) so you can run 3 spanning 30's. Any drawbacks in have spanning screens with different spec cards?
Are there any producers or audio engineers out there who have an opinion on which of the new Mac Pros would be best for a DAW using Pro Tools LE? I'm not able to find much information on whether having more cores or a higher clock speed is beneficial.

View 2 Replies View RelatedThe Sandy Bridge version of MacbookPro's isn't likely to use the quad core version but instead a dual core version with hyper-threading much like the existing lineup offers.According to current Sandy Bridge listings:
[URL]Sandy_B...ile_processors the quad core Sandy Bridge mobile CPU is 45W TDP while the current i7 processor used in MBPs today is only 35W.
Due to size constraints and Apple's push to have 8+ hours of battery life they will be incapable of continuing to offering 8 or more battery hours if the switch to Sandy Bridge 45W quad cores is chosen.
The current 35W offering of Sandy Bridge is only a dual core with hyper-threading. There's still expected to be some improvement in performance as early benchmarks by Anandtech are showing a 10-30% performance boost per core on the desktop variants.
MBP 13" and regular Macbooks should see the switch to Sandy Bridge dual cores due the the integrated IntelHD 200 graphics(which appears to be on par with an ATI 5450) eliminating the need for a discreet Nvidia 320M in lower end models.
When I export a QT video in Final Cut Pro, I look at iStat and my CPU usage is total around 25%, with that usage being spread evenly through the cores. Is there a way to get it to take absolute full advantage of the processors, or is it doing its best job?
I have the new octo 2.8 MP.
I'm looking at replacing my ancient G5 tower with a new Mac Pro, and looking at the options, obviously I have to decide between the single CPU quad-core or the 2 CPU "eight-core" solution.

View 5 Replies View RelatedI just received my new MBP with i7 processor.
What I understood is that the os should recognize 8 cores because of the 4 cores with multi threading. The system profiler however, only shows two.
Was I misinformed or is something up with the hard/software?
I am in the market for a Mac Pro for all my FCP editing. I found a guy who can get me a great deal on a brand new 8 core 2.8GHz Mac Pro, but it is the older version before the "Nehalem" chips.
This computer will be right around the same price as purchasing a brand new quad core 2.93GHz Nehalem Mac Pro.
So what I need to figure out is, what is more important, more cores, or faster newer processor?
Just got a Mac Pro with a single 2.93 GHz Quad-Core Xeon (Nehalem) and it's all working fine, but I'm wondering why this 4-core machine shows 8 cores in Activity Monitor - 8 columns in both the floating CPU windows.
I'm sure the answer's obvious, but it's late in the evening and I did search around the forum threads a little bit before posting.
Just got my i7 iMac the other day. Not all apps use all cores (as expected), but I'm interested to understand this one. Export MPEG2 (TS stream) from EyeTv to AppleTv format (I think it uses quicktime but can't tell).
Check out the pic. Now there are 4 real cores, but OSX is showing the 8 virtual cores. Anyway, given there are 4 cores, what does it imply to have around 50% total utilisation? Two threads? Four threads?
I notice that BOINC (einstein@home) only gets up to total utilisation when its running 8 threads. Does this mean that EyeTv (quicktime) is asking for number of cores and then creating that many threads? EyeTv is only showing one line time in Activity Monitor at around 400%.
Can these utilisation graphs actually be trusted when the 8 cores are virtual?
I am trying to use my MBP 8,2 with two of my four cores shut down in order to preserve battery life. Is this at all possible through 3rd party apps?

View 2 Replies View RelatedHad (used) iBook G4 several months now & thoroughly enjoy it, even tho' I live in the sticks where there's no hi-speed/wireless available; I connect to internet & power, which is fine.
This weekend I went to turn off my iBook & it wouldn't turn off. It's now permanently on, with opening info barely visible (like I need to click on F2 to brighten up, except nothing happens).
Currently using my "back up" computer, my iMac Grape, which is pretty much an antique by now.
I have a problem with my 17'' MBP unibody:
1) Bluetooth is ON:
I can't turn it off. The checkbox is inactive.
But I can turn it off, if I choose "Share my internet connection for other units". (I don't know, if this is the right text in english, because my OSX is in german)
2) Now Bluetooth is OFF:
But I can't turn it on, because the checkbox "ON" is inactive.
It turns only on, if I choose "New Unit"(?). Then there is a new window, that says, that this is only possible if Bluetooth turns on. If I say OK, bluetooth turns ON.
Back to 1)
What's the problem. Why is this f* checkbox for turning bluetooth on and off inactive?
This is not a hardware problem, because I can have stable bluetooth connections.
I did a smc and am pram reset. But it doesn't help.
I was playing around with my mac g4 logic board... ( yes, i know... ) anyways, i press the power, the light turns on, and the fan spinns up then everything just turns off... http://docs.info.apple.com/article.html?artnum=95035
^ my tower, (agp graphics, ftw)
my g5 was on all day. i was working on it this evening and it made a loud pop and shut down. now it won't turn on at all. i tried resetting the smu. no luck. any suggestions?
