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

Oct 25, 2007So I have a 1.8ghz dual G5 with 3gb of ram for work. I mainly work in Adobe CS and do a far amount of Photoshop work. At any given time I may have all of Adobe CS plus Office and a few other apps running -- and a gazillion fonts. Went to the store and saw the new 24" iMac. How would a new iMac compare to my late '04 1.8DP G5? On that same note, how would a new MacBook Pro compare to the above?
View 5 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?

Hardware :: Dell 2407WFP A04 Versus Dell G2410 Versus Dell 2209WA Versus Samsung F2380
Nov 2, 2009I'm looking for a new monitor to go with my MBP, and I'm stuck trying to choose between the ones listed above.
The 2407WFP is a couple of years old now I guess, but it's the rev A04 version, which supposedly fixed the (few) problems with what was otherwise meant to be a great screen. It's an sPVA screen.
I've heard good reviews of the G2410, with its LED backlighting. It's still a TN panel and I hear so much bad stuff about them.
The 2209WA is an eIPS panel which I like the sound of, but it's smaller and lower resolution.
The F2380 is a cPVA panel, the image quality looks better but I've heard bad things about blacks on this panel.
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?

Hardware :: Eyetv 250 Versus TVMax Versus Blackmagic Video Recorder?
Apr 30, 2008I'm trying to decide which product to buy and I was hoping for some advice.
First and foremost I want a device so that I may transfer my VHS tapes to DVD.
Live TV recording is secondary but for the price, I'd like to find the device that suits me best so I can continue to use it after i've transferred all my VHS.
Here are my concerns:
1) I'm going to be moving from the US to Ireland in a couple of months (not sure for how long, could be years+) Obviously there's the whole NTSC vs. PAL, ATSC vs. DVB.
I know with EyeTV 250 it's either or, any ideas if buying some sort of converter is an option (prices, quality)? If I bought just a PAL one, would I still be able to convert VHS or would it be completely unusable in the US?
2) I'd like some sort of HD/Digital abilities. From what I can tell TVMax is analog only and Blackmagic may also be but I can't find more specs on that.
Does this mean they'll be useless once the US undergoes the conversion?
So as of now I'm leaning towards EyeTV 250 but the question are there any forseeable problems with using a PAL to NTSC converter or using a PAL EyeTV in the US just to convert VHS.
Hardware :: Dell G2410 Versus Samsung F2380 Versus Other...
Oct 25, 2009I am planning on purchasing a new display for use (currently) with my imac. I am completely torn between these two models, and cannot make a decision. Any thoughts? I like the Dell because it is LED backlit, thus good blacks and little to no backlight bleed. But I like the Samsung because of the (supposedly better panel and (supposedly) better color reproduction. I like the simplistic look of both of them (though they could look a little better ) so I'm not sure which one to buy.

MacBook Air :: Upgrading From Rev A To Rev B - Real World Observations
Dec 7, 2008I bit the bullet and upgraded from a Rev A 1.6GHz 80GB HDD MBA - to a Rev B 1.86GHz 128GB SSD MBA. I wanted to post my observations on what it's like to upgrade - I know many Rev A owners have - or are thinking about - upgrading to Rev B. In this post/comparison, I refer to "Rev A" and "Rev B". The Rev A is my older 1.6GHz 80GB HDD MBA. The Rev B is my new 1.86GHz 128GB SSD MBA
Caveat - Unlike some (but not all!) Rev A MBA owners, I love my Rev A MBA. I've had zero problems with it. It runs cool and I have not experienced any core shut downs. It would heat up when most laptops normally heat up and the fans would kick. It would cool down quickly when I moved on to something else. With video it never stuttered... Perhaps my Rev A has run so nicely because I don't ask a lot of it. It is a second Mac to my Mac Pro - I use it primarily for email, word processing, iTunes movies and web surfing - on the couch and on the road. It has REALLY been a great laptop and I have nothing bad to say about it...................

View 4 Replies View RelatedMacBook Pro :: Virtual Machine Vs Real Install
Apr 13, 2012I have a mid 2010 MacBook Pro, just that you guys know. For my programming work with the robot (C/Assembler) I will need either Windows or a Linux OS. This is why I'm asking. I really hate Windows and I don't want to install that and besides, Linux is a much better option for compiling my code, etc..Should I use a virtual machine or should I install Linux (Ubuntu) on another partition of my internal HDD.
I will need to install quite a lot of stuff and I'm not sure whether my 4GB of RAM will be enough to run Ubuntu on top of Snow Leopard using a virtual machine. I will need to use another old computer or my parent's desktop for loading to compiled files onto the robot (my IR Tranceiver has a RS 232 connector). I have another old laptop which we commonly use as a 'tryout' computer, but for the most part I want my MacBook to be the computer I use because I cannot take that old (and really heavy) laptop with barely working batteries and super-laggy Win XP to school, where I will do a great deal of the work. So I definitely want Linux on my mac.The partition can be small, I will only need about 15-20GB of space (including the Linux).

Mac Pro :: 6GB Versus 8GB Triple Versus Dual Channels/PS4 Tests
Jun 30, 2009I ran some tests on my 2009 Quad Nehalem to try and determine what was up with the triple Vs dual memory "brouhaha".
I posted the results as a new thread because I think it will be useful information for a lot of quad owners, but it was originally going to be a reply to this thread: http://forums.macrumors.com/showthread.php?t=735845
Here we go. Tesselator suggested 3 tests that could show the differences in speed between triple and dual channel bandwidth.
Quote:
As one idea I would maybe try creating a few very large images (16-bit, blank white, blank black, gradient fill) and then duplicating and deleting that layer repeatedly a few hundred times.
So I did them, 10 times each. I could have gone on, but the results were very very stable after the first 2 attempts.
Set-up: a 40Mpx, 16bit image (8000*5000). First test it was simply filled white; second test: black; and third test a black to white gradient. I added a fourth test, using a real (photo) 12Mpx RAW image from my Nikon D300.
I created (took a while!) an action with 350 repetitions of "duplicate layer" and "delete layer", followed by a red fill to let me know the action was done. The same action was used in all four tests.
The computer was restarted before each of the four tests, which may explain the irregularities on the first 1-2 attempts. Nothing else but PS4 was launched.
The results are interesting:
We can clearly see that the simple white and black fills show a speed difference of around 10%.
We can also clearly see that this difference disappears when a more complex image is used. The use of more complex images represents a much more realistical use of PS.
To make things even more realistic, I also tested RetouchActions's speed test on my own 12Mpx image. I use nearly all of the operations of that action on a daily basis, so it's a lot more representative of the work I do on PS.
Here are the results:
The results are clear: 11% increase in performance using 8GB of ram (Vs 6GB) when working on a 12Mpx image.
Added info: number of page-outs after running the 10 test series (after about 45 minutes of intense PS work):
-17K when using 6GB (1.7K page-out avg).
-10K when using 8GB (1K page-out avg).
For me the results are definitive: unless I plan on working only with full black or full white images (not even black and white!), having 8GB is better, even when working on smallish 12Mpx files. I imagine the differences would have been even greater using bigger file sizes of actual complex images.
What would now be interesting: someone with a 2009MP Octo doing the same tests at 12GB and 16GB.
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.
