How much faster is the 2.7GHz Quad Core Intel Core i5 than the 2.7GHz Dual Core Intel Core i5?

Hi there,
I'm considering buying either a Mac Mini (2.7GHz Dual Core Intel Core i5) or an iMac (2.7GHz Quad Core Intel Core i5). I'm just wondering what the difference in speed is between the two different chips. If both had 4GB of memory would the iMac be a lot faster than the Mac Mini? I'm a graphic designer so I'd be mostly using Adobe Illustrator and Photoshop.
Many thanks,
Richard

How much faster are the Quad-Core Macpros?

Does anyone have any idea how much quicker a Two 3.0GHz Quad-Core Intel Xeon will encode video in FCP, Compressor, and DVD SP, vs. a Two 3.0GHz Dual-Core Intel Xeon?
Thanks.

in some areas motion in particular or exporting mpeg2 from fcp timeline, is slower on this 8 core than on the older dual2gig PPC. this machine has the Nvidea quadro FX4500 which one would hope is faster using motion but doesn't seem to be. that being said compressor rocks using temp Qmaster 4 instance like making 2 pass mpeg2 from a movie file, 90 min movie compressed in 40 min. photoshop and after effects rocks due to multiprocessor use and rendered timeline stuff though not always clean is much faster. having to render more than once and having to watch top to bottom from a QT export out of FCP ***** somedays. Over all it's worth it in my busy every day world

How much fast are the new iMac's?

I've been looking at upgrading my G5 PowerMac for a while and now Apple has just updated the iMac. How much faster are the new models over the just superseded ones and my G5 (spec below).
I mainly us it for my work with Photoshop CS2 and the G5 does a great job most of the time but is showing it's age. I was looking at the 2nd model but for not much more you can get the 27inch screen with better upgrade options.

Hi Craig,
even the very first 2006 released Intel iMacs were faster than the G5 iMacs including yours.
See this Barefeats test http://www.barefeats.com/imcd3.html
Check additional tests on Barefeats on older iMacs against newer ones http://www.barefeats.com/
The new 2010 iMacs of any sort run circles around the 2006 iMacs, so you are in for a very pleasant surprise

How much faster are the new iMacs from my older Macpro?

Anyone have any idea how much faster a new iMac would be than my older Macpro? Please see attached image. Thanks!

There are a number of benchark tests for the new iMacs. A quick Google search found:

Macbook pro or imac, how much faster is the imac?

I work on huge photoshop files. Up to 15gb sometimes. In the studio I have a macpro 8 core, 32gb ram. However, I also do work abroad, and for this I bought a macbook pro 2.4ghz intel 2 duo, 3 years ago. when travelling I keep my files to 1GB or less. It's still painfully slow.
I need a faster portable option. Can anybody advise me on the new macbook pro, vs macmini, vs imac? how do the fastest macbook pro hold up against the fastest imac?

Take a look at this. There are probably a few more on the web that you can find.
http://www.primatelabs.ca/geekbench/mac-benchma
The fact is that the iMacs have faster processors than the MBPs but the new MBPs will be significantly faster that your old one. With that said, your MAC PRO will still be faster than both the new MBP and the new iMac.
I suspect that if portability is an issue, the MBP probably should get the nod. The iMac's are big and heavy.
Ciao.

How much faster now vs. 4 years ago?

My computer (Apple iMac Desktop 24" -- 2.8 GHz Intel Core 2 Duo, 2 GB RAM, 320 GB Hard Drive) is coming up on four years old. I use it extensively for video production, including Final Cut Studio.
How much faster will the newest iMac model be (for Final Cut Pro rendering, DVD writing, etc.)?
The age-old question: Buy soon, or wait till even better models come out?

How on earth do you manage with only 2GB of RAM? Doubling that, or better would speed up your Mac.
How much faster will the newest iMac model be (for Final Cut Pro rendering, DVD writing, etc.)?
Nobody knows except Apple. The rest of us will know when they anounce it! And of course, Final Cut Pro has been discontinued.
The age-old question: Buy soon, or wait till even better models come out?
Definitely!

How improve MathScript speed & how much fast in 8.2

Hi
Right now I'm working on data acquisition and process.
For processing the data, I'm using the MathScript.
However whenever I run the vi, it's extremely slow because of the MathScript.
Like one of this forum's answer, I did use multiple Mathscripts and try to put
an unnecessary calculation outside MathScript, but still it took a lot of
time to run the vi.
Is there any tip or method improve speed of MathScript?
Beside, I heard that the MathScript in the labview 8.2 has a significant speed improvements.
So, how much faster, compare the labview 8.0?
Maybe it's a stupid quesiton, but I really need to know before I try labview 8.2.
Thank you in advance.
Have a good night.
Best regards
aggie

Hello,
MathScript is implemented on top of LabVIEW. MathScript is also a typeless language while LabVIEW is strictly-typed. The combination of these two factors make MathScript run slower than native LabVIEW code. However, there are some steps to take in order to improve the speed of MathScript. You mentioned two of them: Moving calculations outside of MathScript and breaking larger scripts into multiple smaller ones. Another thing to look for is if the MathScript node is inside a for or while loop. Passing variables into and out of the MathScript node during each iteration of a loop is very expensive. It is better to use a MathScript global variable to store variables that are only updated in the MathScript node. But perhaps the best method to improve the speed of the MathScript node is to vectorize your code. This means taking operations that are performed in a loop and instead performing them on the entire matrix at once. For example, if you want to implement a clipping algorithm that clips values of a matrix greater than one, the following code will work:
for i=1:length(A)
    if (A(i) > 1)
        A(i) = 1;
    end
end
However, an approach that will run substantially faster is to use matrix indexing to do the work for you. The same operation can be performed in one line:
A(A > 1) = 1;
Any time you see code that is iterating over elements of a matrix, ask yourself if it's possible to vectorize the code.
The speed of MathScript has been improved in LabVIEW 8.2. The most notable difference is in the compile speed. This means the MathScript Window is more responsive and that your wait is shorter when running a VI after changing the MathScript node. A run-time speed improvement was made for matrix indexing (hence another reason to try to vectorize your code). These two speed improvements can be quantified as follows:
Up to 300% compile time speedup
Average of 500% speedup for indexing with vectorized operations
The indexing operations that realize the greatest improvement:
Writing operations such as
A(:, 1:3) = B;      % Replacing consecutive (or nonconsecutive) columns with a matrix
A(1:3, : ) = B;       % Replacing consecutive (or nonconsecutive) rows with a matrix
A([1 3], [2 4]) = B; % Replacing elements (nonconsecutive rows and columns) with a matrix
Reading operations such as
B = A(1:2:end);       % Reading elements (consecutive or nonconsecutive)

How much faster or better is the new iMac... really?

Hello all,
I have a 20" 2.33Ghz C2D iMac w/256Meg video RAM, and 3Gig of RAM. I understand that many factors come in to play when you compare the over all speed of a computer. How much faster, over all, is the new iMacs over the system I have? Has anyone tested the two next to each-other yet? I am sure the new one is faster in some ways, but is it really lots faster in over all performance, or just a little?
Apple //GS

Hi Patrice,
Within Apple’s slim new 21.5- and 27-inch iMacs are NVIDIA GeForce GPUs, based on our new Kepler-class architecture, which helps make them up to 60 percent faster than last year’s models. This follows news in June that Apple’s 15-inch MacBook Pro with Retina display uses Kepler GeForce GPUs.
The new 27-inch iMac offers the GeForce GTX 660M as its base GPU, with even faster GeForce GTX 675MX or GeForce GTX 680MX GPUs available. The 21.5-inch model comes with the GeForce GT 640M GPU, with an available upgrade to the GeForce GT 650M GPU.
http://blogs.nvidia.com/2012/10/big-imac-news-less-heft-more-kepler/
So, any Apps that use the GPU to assist GPU should be much faster.
Though I don't see it listed here, it may be too new, I suspect it may be supported...

I need to sort very large Excel files and perform other operations. How much faster would this be on a MacPro rather than my MacBook Pro i7, 2.6, 15R?

I am a scientist and run my own business. Money is tight. I have some very large Excel files (~200MB) that I need to sort and perform logic operations on. I currently use a MacBookPro (i7 core, 2.6GHz, 16GB 1600 MHz DDR3) and I am thinking about buying a multicore MacPro. Some of the operations take half an hour to perform. How much faster should I expect these operations to happen on a new MacPro? Is there a significant speed advantage in the 6 core vs 4 core? Practically speaking, what are the features I should look at and what is the speed bump I should expect if I go to 32GB or 64GB? Related to this I am using a 32 bit version of Excel. Is there a 64 bit spreadsheet that I can us on a Mac that has no limit on column and row size?

Grant Bennet-Alder,
It’s funny you mentioned using Activity Monitor. I use it all the time to watch when a computation cycle is finished so I can avoid a crash. I keep it up in the corner of my screen while I respond to email or work on a grant. Typically the %CPU will hang at ~100% (sometimes even saying the application is not responding in red) but will almost always complete the cycle if I let it go for 30 minutes or so. As long as I leave Excel alone while it is working it will not crash. I had not thought of using the Activity Monitor as you suggested. Also I did not realize using a 32 bit application limited me to 4GB of memory for each application. That is clearly a problem for this kind of work. Is there any work around for this? It seems like a 64-bit spreadsheet would help. I would love to use the new 64 bit Numbers but the current version limits the number of rows and columns. I tried it out on my MacBook Pro but my files don’t fit.
The hatter,
This may be the solution for me. I’m OK with assembling the unit you described (I’ve even etched my own boards) but feel very bad about needing to step away from Apple products. When I started computing this was the sort of thing computers were designed to do. Is there any native 64-bit spreadsheet that allows unlimited rows/columns, which will run on an Apple? Excel is only 64-bit on their machines.
Many thanks to both of you for your quick and on point answers!

How much faster is Oracle.DataAccess.Client over System.Data.OracleClient ?

Ok, I can use two differenct data providers in VisualCSharp/.NET:
1.) MS built-in data provider:
using System.Data.OracleClient ;
2.) Oracle ODP.NET data provider:
using Oracle.DataAccess.Client ;
How much faster is Oracle over the built-in access provider ?
Does Oracles ODP use MS basic ADO.NET as underlying layer
or does it bypass it ?
What are the other advantages when I use Oracle ODP?
Is there a side-by-side comparison chart between the two access methods ?

I would say that it is both for speed and for functionality. The ODP data provider has Oracle specific functionality that is not available via the MS data provider.
From the ODP.NET page:
ODP.NET includes many features not available from other .NET drivers, including a native XML data type, the ability to bind array parameters, RAC tuning, and statement caching.

How much faster on an iMac?

I've been editing and burning soccer team video on my 12" PowerBook G4 (1.5G, 512 RAM). Needless to say its been painful but very successful. I've pretty much talked myself into upgrading to an iMac mainly to expedite the burning of that first DVD. How much faster can I expect to burn (render) that first DVD. Typically I'm filming about 1.5 hours of video and then burning a couple copies. That first DVD currently takes about 6 hours to burn.

on my old Cube, increasing RAM beyond 1GB (under OsX) made a significant jump, and switching to Intel adds another reallife noticeable speedbump ...

How much faster will ipad 4 charge with new charger

Has anyone seen a number that tells us how much faster the new ipad 4 will charge?
Can anyone guess how much faster the ipad 3 would charge with the new charger brick?
I can't even find estimates in articles on the web... Maybe we won't know till some of them ship?
Thanks,
Tom

Thanks... That's pretty disappointing - 20% more power and only 5-7% improvement in speed.
I'm sure hoping the ipad 4 does better than that.
Cheers,
Tom

How much faster is an i7 2.66GHz vs a Intel Core Duo 3.06GHz?

Is there anywhere you can go to see how much faster these new crop of i7 chips are vs the chips they are replacing? It is always hard to try and quantify how much more you are willing to pay when you have no idea how much faster it is going to be?

Excellent, the chip I just bought is the 13th fastest one made right now.
That is much better than buying the 160th fastest chip. Interesting read an thanks for the link.

How much would be the monthly cost to host a small Linux instance in Azure?

Hello Guys,
I just wanted to ask how much would be the monthly cost of hosting a Small instance of Linux VM in Azure. I doubt this
detail has all the pricing parameters included. It’s just the VM itself it seems.
I know there is a pricing calculator but I’m not sure what parameters would be involved for this very basic instance. If you guys can give me an example calculation or at least point me to the basic parameters to include in the calculation, I will really appreciate
it.
FYI – these instances will be running a FreePBX system. I hope this helps to point out which parameters should be considered and included in the calculation.
Thank you very much,
Arnel
