Mac Pro :: Best For Pro Tools 8 Cores 4 Cores?
Mar 16, 2009I 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 :: Hyperthreading Versus Real Cores
Sep 9, 2010Assuming all cores are maxed out, how would the performance of the virtual cores stack up against physical cores (say, in the instance of a i7-620m)?
View 2 Replies View RelatedMacBook Pro :: Sandy Bridge MBP Is Dual Cores?
Dec 14, 2010The 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.
MacBook Pro :: System Profiler Only Showes 2 Cores?
Aug 10, 2010I 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?
MacBook Pro :: Quad Core Saving Battery Life By Only Using Two Cores?

Mac Pro :: What Does More Cores Mean
May 14, 2008I 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, 2008People 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.

Mac Pro :: Which Video Editor Make Use Of All Eight Cores?
Feb 16, 2008Which, 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.

Feb 23, 2009Are 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?

Jun 16, 2009I 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?

Aug 3, 2009Just 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, 2009Just 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 not trying to use 2 copies of the same thing on different machines, I just want to put a new os on one machine and move the existing one to another.I am reluctant to purchase the Mac Box Set version of Snow Leopard for the iMac because I do not want or need iLife and iWork.
View 2 Replies View RelatedMacBook Pro :: Running Extremely Slowly And Fan Continuously Running Loudly?
Jun 4, 2014My Macbook Pro (from mid-2010) has recently started running EXTREMELY slowly, and the fan continuously runs loudly. From other posts, I have checked my activity monitor to see if any process is taking up a lot of the CPU % and have found that nothing seems high, except the kernel_task which, from what I understand, is supposed to be high. I have also attempted to reset the SMC which didn't fix the problem either. I have taken my computer to the genius bar 3 times now, and they keep telling me nothing is wrong (because it works perfectly there), but when I get it home the fan comes back on, and everything runs slowly.

MacBook Pro :: Late 2008 (2.53/4GB Ram) Running 10.7.3 Seems To Be Running Slower?
Mar 15, 2012My Mac feels as if it is running slower these last couple of months. I have thought of pursuing a commercially available "clean up" product, but thought I would try the community first and also for pointers using the Mac's own internal diagnostics or system improvement capabilities. Any and all advice is most welcome. I have a 250GB hard drive that is half full, I always update to latest revisions and have an extra high-speed internet connection. Computer is not heavily loaded with apps and typically using Firefox for browsing. (MS Office for Mac as well, but usually limited to one program such as MS Word or Excel at a time.) No heavy graphics utilization. Videos from the internet load slowly and some are choppy. Even scrolling just doesn't seem "brisk".

View 2 Replies View RelatedIntel Mac :: Running Constantly Hot - Changed The Hard Drive But It Is Running Hot?
Mar 5, 2012I've had an iMac for just about a year and over time I guess I just didn't notice but the machine always ran very quietly. At the same time the back of the computer would heat up so bad that it would nearly burn my hand if I left it there. Well last week I decided to upgrade to Lion from Snow Leopard and when I did the install failed and froze up the hard drive. I took the computer in to the apple store and they determined that it had to have a new hard drive installed because the old one (only a year old) had a physical malfunction (was broke). So anyway I have my iMac back and get it started up, backed up from time machine, and then finally get Lion istalled - and now all of the sudden I notice that the fans in the computer are CONSTANTLY blowing - I can hear them spinning and can hear the air venting out of the back of the computer - and the computer is STILL really hot on the backside of the screen.
So now I am wondering if the originial problem was the computer heating up and if that may have broken the otherwise good hard drive? Also now that I have a new hard drive - should I be concerned about the fans being on ALL the time? I mean they never go off. Even when I leave the computer for hours and come back to it and the screen is asleep the fans are STILL buzzing away at top speed. Here is the stats on the computer at the time that I'm typing this note - there are no other programs running than Firefox and Mail. Also - I don't know what the optical drive is exaclty - but if it's the DVD drive (superdrive) - there is nothing in the DVD disc drive
