Comparing 13-inch:2.8 dual to 15-inch:2.5 quad

Is there that big of a difference between the 2.8 dual vs the 2.5 quad?

that's an easy answer.
go with the 15' for what you'll be using it for. it has it's own discreet graphics.
the 2.3GHz is better because of the quad core design. especially true for video editing.
the 13' will also do what you want but slower because of the built in intel video which is driven by the processor and uses part of the system RAM.
if you're not worried about speed and are more concerned about portability, then you can stick with the 13'.
whatever, you decide to buy, you'll be happy with either macbooks. just make sure you max out the RAM for your purpose.

This is a good deal.
I paid that for my 2009 27 inch iMac with similar specs through an Apple Reseller.
Is this from an individual or Authorized Apple Reseller?
If from an individual, then there will be no type of warranty.
An Apple Authorized Reseller wil have a warrany period of 30 days to six months depending.

It is the OS. have you ever heard of UNIX? If you installed linux on your mac it work run just at fast... windows is very resource intensive. Also apple make sure the drivers are correct and run properly while windows could care less. Someone else can give you more reasons.

IMac 21.5 inch 3.6GHz dual core works virtually like a Quad?

I read on apple.com that the iMac 21.5 can be configured to have 3.6GHz processor which supports hyperthreading. Does this mean, this will have 4 virutual processors/cores?
This machine has 3.6GHz dual core processor so, 3.6 + 3.6 = 7.2. Does this mean it is only approximately about a core less compared to a Quad core machine (Mac Pro or iMac)?
I'm just trying to understand all this and choose a machine which is not an overkill. I have a 2 year old Macbook pro which is fast enough for audio work but I'm looking to do video editing with a new desktop that I want to buy soon.

It seems the best thing to do is wait for some more benchmarks. Barefeats has some good ones, unfortunately they don't yet have a 3.6GHz i5:

Lost all Apple App's in Upgrade from G5 Dual 2.5GHz to the G5 Quad

I just got the new G5 Quad and did the Firewire rehost of all my data. Interstingly enough, all my app's like Reason, PhotoShop, Premier, Poser, Bryce, Maya, even MS Office and ZBrush moved right over with their respective serial numbers however Shake, Motion, Soundtrack Pro, Final Cut Pro HD, Compressor, LiveType and Cinema Tools all refuse to work without their serial numbers being re-entered. If you try to re-enter your serial# it tells you it is no good.
All I could do was throw all the Apple professional applications away and re-install them. Then the system would accept the same serial #'s it refused to accept before. I'm not sure is will work for all Pro App's yet as I've only had time to do Shake and Motion.
Anyone else seen this?
G-5 Quad 2.5GHz, Powerbook 1.25GHz Mac OS X (10.4.3)

Did you use the Migration Assistant? If so, that could be the problem. It probably didn't copy some important invisible files. I always suggest using Carbon Copy Cloner via Firewire Target Disk mode to clone a drive over.

Will my specific computer model (iMac 21.5-inch 2.5GHz Quad-Core Intel Core i5, May 2011) support an upgrade to 16gb ram and 1 or 2tb hd?

Just ordered it it says in Features under RAM, that it supports up to 8gb, but does that mean 8gb for each slot, or in total?
And for hard drive I'm curious as to the max supported as my old ~2008 macbook only supported up to a 500gb hd I've read. Looking to perhaps upgrade to 1 or 2 tb in the future. Also are iMac hds 2.5" or 3.5"?
Thanks for the info if anybody knows, can't seem to find this information anywhere

Issue with HP Z820 64GB RAM and dual Quadro K4000's and rendering and playback performance

I'm having major issues with performance on my system (running windows 8.1. Premiere CC 7.2.2). My friend in the office here has a Mac Pro (2013) with 6 core cpu and dual D500's and I have dual Xeon 2665's and dual K4000's.
The problem is that he can export twice as fast as me on mercury software and almost 3 times faster on Mercury GPU. He can also add twice as many affects before his system drops frames (using same settings and video file). When I go to GPU-Z my gpu's are hardly working with GPU export selected... with software only my CPU's get to 60% load max whereas his CPU get's to about 84%. Am I missing something? I know the D500's are almost the same as W8000's (and he has two), but dual K4000's shouldn't be that far behind? And how does selecting cpu exporting get him an export time of 6 minutes compared to my 15 minutes when I have a 32 threads to work with??
Am I doing something wrong? Have I got a setting somewhere that is causing this that I might have missed? Are dual D500's really THAT much better than dual K4000's? AND HOW is my 7k+ machine that much worse than his £3200 mac?
Please help. I'm losing my mind here!
Thanks
Edit - Would just like to add that the video files we are using are pro res 422 and that I have the latest bios and latest nvidia performance drivers

That HP Z820 should kick the Mac pros butt! For example we run Autodesk Flame systems ( 150k software) on the Z820's with Quadro 6000 cards and they fly. We also had a new mac pro in for testing a few months ago w the dual fire pro cards all decked out and it was crap next the the Z820. Of cource the new MP cant run allot of highend software because of its lack of nvidia support and the firepros lack of open GL but we did run premier and smoke etc on it for testing. ( Although i thought it looked cool the total lack of exandability and nvida support was to much so we sent it back). Graphic workstations need PCIe expandability and a choice in GPs.
Anyhow here are a few observations:
-Software being used will dertermine the hardware purchased,
-The dual xeons at the much lower clock speed are meant to work 24/7 like a lamans endurance race, not a sprint race. Better to get highest frequency xeons.
-Having dual CPUs with all thoughs cores will only work with a software that is properly mulithreaded, premier is definetly not one of those softwares so you not getting any advantage.
- the advantage to Quadro cards are much more noticable in 3d tha 2d. If your running Autodesk maya, 3ds max or the recently disscontinued XSI you would be flying compared to the W7000.
-dual GPU cards do not preform at twice the speed. On average the second card gives about a 10 percent boost.
-At present ( and as akways) , nividia Quadro drivers are much more uptodate and bug free compared to ATI highend cards. This will inevitably change as openCL over takes openGL, until then Quadros are the clearly superior cards for those with DEEP pockets.
-I think you would have been far better off with a single Quadro 6000 vs dual K4000s. Also any higher end ATI firepro card would have worked since Premier now uses open CL and no longer needs openGL. Main advantage to Quadro at this point ( besides 3D ) is to be compatible with the most softwares and get the best and most optimized drivers. Firepros will work properly in far fewer softwares at this point but I can see a day over the next few years this may change but not as of yet in 2014. So his W7000 wins this sprint race in this single simple example but in most any other situations your cards will actually work and win. I like saving money like the next guy but I even purchase Quadro cards for my home use and experimenting, but Im not a gamer.
-FYI: Cuda core count no longer is true measure. For example older Fermi cards worked at twice the frequency than the newer kepler architecture so in effect today you need double ( actually more) the amount of cuda cores to equal the older cards. Also the true compute power in the new Keplers is also much inferior to the older cards. Its all creative advertiseing today more akin to creative accounting / smoke and mirrors. What im trying to explain is when people read the charts that show the cuda core count and say the higest is best is completely not true. It may have the most "cores" but it will not render correctly, double percision is missing, colors may pop, anti aliasing is inferior and inconsistant, interaction ( most important) and shaders will be buggy or missing. There are very good reasons people spend money on highend Quadro cards but the charts and reviews generically speaking never understand or can even test for this stuff.
-Even given the above scenarios your Z820 should be killing your competition. Using a decked out Z820 is way overkill for anything CC. ( Kinda like driving an F1 to get groceries.) get your HP rep to come over and replace / test your rig. Its free and covered in your coverage.
I am CLEARLY not a tech guy as my talent in is creation and design but I overhear the tech guys talking.

Macbook Pro Compare Question for Premiere CS5.5

Hi, I am ready to buy a macbook pro to handle premiere cs5.5 processingwedding films that I edit on my imac 27".
Due to limited budget, one part of me wants the 15" screen but the 13" is $300 less expensive with the 2.8 dual core vs the 2.2 quad core of the 15". Based on the specs below, is it worth the 300 more to get the hard drive power of the 2.2 quad core?
The 13" has 250 more GB hard drive. Will the 13" macbook pro be suitable enough to import DV film, process the final files and burn DVD's quickly and effectively?

>not quite clear what minimum of two disk drives and 7200 rpm means?
A 5400rpm drive does not transfer data fast enough for video editing
Trying to use only ONE Hard Drive for Video Editing
You are a music conductor, with a baton that you use to point to various parts of the orchestra... this is like Windows pointing to various parts of the hard drive to do Windows housekeeping or to load program segments for various functions
Now, at the same time and with the same hand... while still using the baton to conduct the orchestra... pick up a bow and play a fiddle... this would be doing something with your video file at the same time as all the other work
You as a person cannot do both at the same time with the same hand
A computer is a LITTLE better, in that it can switch from one kind of task to another very quickly... but not quickly enough for EASY video editing
You need AT LEAST two hard drives (separate drives, never a partition http://forums.adobe.com/thread/650708 for more) with Windows (or Mac OS) and software on your boot drive, and video files on a 2nd drive so the boot drive is not slowed down by trying to do everything
I find that the three drives I use work very well for me, for editing AVCHD video... some people use a 4th drive, so video INPUT files are on drive three and all OUTPUT files are on drive four... I only bought a mid-tower case instead of a full tower case (my bad... but had to fit in the space available on my office desk!) so I use the three drives that will fit
Depending on your exact hardware (motherboard brand & model AND USB2 enclosure brand & model AND external hard drive brand & model) AND the type of video file, you may... or may NOT... be able to use an external USB2 hard drive for SD (Standard Definition) video editing
Steve Grisetti in the Premiere Elements forum http://forums.adobe.com/thread/856208 and Jim Simon in the Premiere Pro forum http://forums.adobe.com/thread/856433 use USB externals for editing
A USB3 hard drive connected to a motherboard with USB3 is supposed to be fast enough for video editing (I don't have such, so don't know) but eSata DOES have a fast enough data transfer for video editing... I have not used the eSata Dock below... for reference only, YMMV and all the usual disclaimers

Big jump from G3 iMac to G5 Dual!

I'm buying a secondhand (fairly new) G5 Dual to replace my old iMac 400DV (OS 9.2.2).
I have questions:
What should I look for in the way of problems, apart from pixel deaths?
Will I be able to install my 9.2.2 applications?
Will the G5 be able to read my CD reference originated on the G3?
Anything I particularly need to know?
The most pressing question is - how I pay for it?
Thanks in advance for any assistance.
If you would kindly reply in a way which is understandable by a technophobe, I would be most grateful!

I'm buying a secondhand (fairly new) G5 Dual to replace my old iMac 400DV (OS 9.2.2).
What sort of G5? What's the price? What's the specs of the machine and video card? What are you going to use it for? Want to 3D game or not?
Some are better than others and the Dual series are about to be obsolete, they are over 3 years old already and most of the rest of the new Mac consumer line are already Intel based Dual core processors.
What should I look for in the way of problems, apart from pixel deaths?
Pixel deaths only apply to monitors. But the Dual PowerMac G5 series (not the Quad) suffer from a beeping power supply. Sometimes it can be remedied with installing Tigers' developers tools and Processor Preference pane (turn off Nap Mode)
Depending upon which PowerMac your getting, depends upon what sort of PCI cards, video cards you can upgrade to.
Will I be able to install my 9.2.2 applications?
I still think Tiger will allow the installation of Classic environment which is needed to run Classic applications. The problem of course is the apps OS 9 based installer disks might not run in Classic. Then there is copy protection schemes that might need installation directly from the apps disks, which might not work. Font and printing problems, trouble with connecting scanners and driver software is common with Classic. Most just switch to Mac OS X, it's easier.
Will the G5 be able to read my CD reference originated on the G3?
Yes, if you mean files and not a app installation disk of some sort.
Anything I particularly need to know?
Yes tons.
The best way to go to Mac OS X is directly, with all new apps, etc. Bouncing back and forth in Classic while your trying to learn Mac OS X on the same machine is not going to be fun, you won't know what's right or wrong. Use your older Mac for OS 9 until your completely up on the new machine. Use the older Mac for connections to old scanners and whatnot. Is my recommendation.
Also since your making such a great leap, perhaps you should wait until the Intel processor PowerMacs (Mac Pro's we think it will be called) and Mac OS 10.5 arrives (aka: "leopard") sometime this year.
This way you jump from a old OS and old processor type to a new OS and a new processor type in one stop. Without wasting money on software or software upgrades.

The most pressing question is - how I pay for it?
Well if you don't have money or credit...
Your really behind in the times, may I suggest you do some online reading at various Mac websites so you can get up to date with the latest information to make better decisions.

MacBook Pro Late 2013 13 inch & games like Minecraft.

Hey, I'm just wondering if the MacBook Pro Late 2013 - Mid range 13inch laptop will handle games like Minecraft on high at 60fps? I'll also be using the machine for video/photo editing. Thank you.

That should easily be possible. You would get up to 100 on the lowest spec model (13 inch, 4gb ram, quad core i5 2.4ghz processors, intel iris integrated graphics)

Will macbook pro (13-inch: 2.7 GHz, 8GB Ram), run logic pro9/pro tools8?

i have been looking at macbook pro's for a while and i thought that this would run the software fine, but i heard that it may not, i am not at all experienced with the was mac's in general distribute the cpu usage in comparison to windows and how memory/power hungry they are, obv they are not as bad as windows, they are alot more efficient, but thats as far as i know. ijust wnodered whether i needed to buy the macbook pro 15 inch with the quad core proicessor, will this be significantly faster and run the software logic pro9/pro tools8 better...please help me???
Thanks alot
Ben

It would run it, but you'd do a lot better with the 15" i7 model
If you buy the RAM upgrade from OWC it would save you some cash to put towards the better spec machine ...

I7 2.7 dual VS i7 2.0 quad

which is faster, 2.7 dual i7 or the 2.0 quad i7 for the imac mini, I dont really care for the video card, just need the horse power
Thank you

There is something of a paradox with these machines.
If running a single application that is not multithreaded
and only having one or two apps active, the dual 2.7 will
actually be faster for that app.
However, if running an application that is multithreded
(Handbrake comes to mind) or having several applications
actively running at once, the quad 2.0 will actually be faster.
It all depends on the applications used and whether they can
utilize multiple cores.

Is there a noticeable difference between Dual Core i7 and Quad Core i7?

Hi everyone.
I'm going to be a college freshman this fall. I'm looking at 13" MacBook with Retina Display with dual core i7. I'm also looking at the 15" MacBook Pro with Retina Display with Quad Core i7. I want to major in science and have a concentration in photography, which means that I will run programs like Excel, PowerPoint (or keynote), and Photoshop.
Anyways, will there be a noticeable difference between a Dual Core i7 processor and a Quad i7 processor?
Thanks!

Ceteris Paribus, the quad-core will be twice as fast as the dual-core.

FYI--Compressing times of a dual 450 vs dual 1.25 vs Quad

Just got my quad and after some hoops to jump thru I have fcp 4.5/compressor 1.2 running fine now.....
Now these times are not 100% accurate....off by a few minutes here and there but this is what i've got from going from two g4's dual 450 and dual 1.25 to a G5 Quad.....
This project is 1 hour and 40 minutes with a fair bit of colour correction, a third of it time remapped, and a third of it with a widescreen matte...
dual 450 - just the video compress --approx. 15 hours
dual 1.25 - just video --approx. 10 hours
Quad - just video compress---under 1 hour and 30 minutes....
All I have to say is holy crap batman!!
For me getting the quad now certainly makes a lot of financial sense as I will be able to finish projects a lot faster. I have a back log of about a dozen projects. Can now ship off my slowest mac to a friend who can work for me as well.....:)
The Upgrade is coming in the next week or two and I should see a bit of a difference there as well.....
WOW WOW WOW.......
