Mac Pro :: Best For Pro Tools 8 Cores 4 Cores?

Mar 16, 2009

I Have been agonizing over which Mac Pro would optimize the performance of my Digital Audio Workstations, Pro Tools in particular. Honestly, I have been back and forth with deliberating that now I am burnt out,

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?

MacBook Pro :: Number Keys On Keyboard Are Malfunctioning Besides Number 0

Sep 2, 2014

-Processor: 2.4 GHz Intel Core i5
-Memory 4GB 

Only the number keys on my keyboard are malfunctioning besides the number 0.  For example when I press 1 it appears as q1.  When I press 2 it appears as w2.   

I am not sure if I accidentally pressed something on my keyboard that has changed the functioning of my number keys. I've tried fidgeting with the keyboard settings in System Preferences and holding down the f6 key but nothing has worked. 

MacBook Pro, OS X Mavericks (10.9.4)

Mac Pro :: What Does More Cores Mean

May 14, 2008

I 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?

Mac Pro :: Use Lightroom And 4/8 Cores?

Dec 15, 2008

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.

OS X :: Application To Turn Off Cores?

Jan 7, 2010

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?

Mac Pro :: Which Video Editor Make Use Of All Eight Cores?

Feb 16, 2008

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.

Mac Pro :: 2.8 Versus 3.0/3.2Ghz Quad Cores

Feb 23, 2009

Are the incremental steps in processor options worth it? are they significant enough to notice performance increases? especially heavy files in photoshop

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?

Mac Pro :: Having More Cores / Higher Clock Speed?

Apr 20, 2010

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.

MacBook Pro :: Sandy Bridge MBP Is Dual Cores?

Dec 14, 2010

The 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.

Mac Pro :: Final Cut Pro Rendering Using Full Capacity Of 8 Cores?

Jan 18, 2008

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.

MacBook Pro :: System Profiler Only Showes 2 Cores?

Aug 10, 2010

I 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?

Desktops :: Cores Or Faster Processor For Video Editing?

Jun 16, 2009

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?

Mac Pro :: Quad Core MP Shows 8 Cores In Activity Monitor

Aug 3, 2009

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.

Applications :: Can Utilization Graphs Actually Be Trusted When The 8 Cores Are Virtual

Nov 17, 2009

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?

Desktops :: One Or Two Processors?

Sep 23, 2008

I recently acquired a used G5. When I look at "about this mac", it tells me that I have a two processor, 2ghz machine but when I open the case I only see one G5 icon. The serial number is from late 2005. I just wanted to make sure that I have two processors as I'm planning on selling/trading up to a mac pro.

MacBook Pro :: New Processors And 8GB RAM

Jan 7, 2009

So the new MacBook Pro 17" can have 8GB ram and New MacBook Pro 15" can't anyone figured out way it is that way, cuz only difference I can tell is the new processors but those don't matter with memory it is the chip and as far as I can tell is the same unless apple is not saying something. I don't have $1200 for 8GB of Ram anyway, but be nice to know my new MBP 15" in a year when the prices are lower can have 8GB Ram.

Mac Pro :: Mac Pro Processors Be Swapped Out?

Feb 22, 2010

I'm about a year into the Mac platform after switching from pc. My first Mac was a 17" MBP and I'm looking to get a Mac Pro. Like most I'm waiting to see when the new ones will come out. I have always been curious and just wanted to know can the processors be swapped out like on a pc? I realize this involves mother board issues and whatnot but the processors we're waiting for are the same ones that can be purchased by anyone. I always wondered why someone with say a 2008 Mac Pro could not just simply swap out the processors since the tower itself is still the same. Again, I'm fairly new but just was wondering if anyone knew the answer (s). Thanks again for any insight as I'm trying to really learn and understand the Mac system under the hood so to speak.

Mac Pro :: Getting Multiple Processors Or Not?

May 1, 2010

I am looking into getting a new mac. I am a photographer and my major concern/application is Photoshop. At this point in time apple will be releasing (soon I hope) new models. When they come out, I believe I will have the choice of finding the current models somewhere or getting the just released products. Money is a little bit of an issue. I would like to keep as much of mine as possible and give apple as little as I can. That being said I have no problem investing what I need to. I just don't want to waste on something that isn't going to give me any real gain. Like i said I mostly use photoshop. will photoshops usage of multiple processors equal the cost or should I save the money. Purchase the a quad or what ever they release ( 6 core) and put the money saved into memory and ssd drives or drives.
