Mac Pro :: Future Of Software Development - Multiple Core Usage
Sep 21, 2010
I am on the verge of buying my first Mac Pro and have a few questions to those with some insight into the software development world before I make my decision on whether to buy a 1cpu or 2cpu MP.I am buying this computer to last me for many years and because of that wondering alittle about the future of software:-)1) Are software developers in general shifting towards making programs that utilize multiple cores? Will games, business software, leasure software etc. slowly start to be made with multiple cores in mind? Or is the trend that multiple core usage is mostly for professional editing?

This will primarily be used for application development, primarily with Xcode.
I'll also use it for photography/video (GIMP, and stepping into Aperture and Final Cut Express).
I've ruled out an iMac because I want plenty of expansion options.
I know Xcode scales linearly depending on the number of cores but I am trying to look for a sweet spot in performance and budget. I want something I can grow with for a few years (i.e 3-4).

It's the last question before I buy the MBA. I have a program that can run under Win or MAC. That's a Picture convert and compile program work with my project. This program needs 100% CPU to and last 15 minutes to work under my old Pemtium M 1.6Ghz notebook. Usually I do my job use my notebook in home or my desktop PC in office. But occasionally I need to do some compile outside the office.
So I really need to know whether the MBA will definitely shutdown one core when the CPU usage is 100% and last 15 minutes? Or maybe you can tell me if the MBA will shutdown when rendering a project in Mayar or 3D Max last 15 minutes. It's important to me before I buy the MBA. I just need a light notebook and I can do some hard job occasionally, but reliable. I like a Fujisu S6510 too, but it is too expensive and heaver than MBA.

For those of you with a new i7 iMac, if your machine is completely idle, what does your CPU usage look like in Activity Monitor? I'm routinely seeing Finder consume 70-90% of my CPU. The single CPU bar meter view in the dock is basically pegged most of the time. The graph shows it as system usage. If I open the CPU History window, all 8 threads look like they're just about maxed out.

I'm looking to get a MBP, but since i can't swing the $3k+ for it (laptop, warrenty, accessories, and software) I want to get a mac mini. How well does it run the Adobe suite? can i hook it straight up to my own vga / dvi moniter? will my standard windows keyboard / mouse work with it, usb? Where is a good place to find benchmarks on this product?

i was wondering if anybody here was developing for Windows Mobile 7 on their Mac? It may seem strange but I'm a Windows Mobile 7 developer and I really, really like it.
I know it goes against the grain here but I am a huge fan of Visual Studio. I really enjoy CSharp, C++, and VB.net. Though I'm partial to CSharp.
Anyway I joined the beta SDK program (its free) and I really enjoy programming for Windows Mobile 7. I noticed many other developers are using Mac as well. In fact, one of the presentations you can view shows Microsoft employees using a MBP.
I'm flipping between VMWare and Bootcamp because the XNA code requires a DX10 card which VMWare doesn't use. Though VMWare is great for Silverlight stuff.

I just got my first Apple product, a 13.3" MacBook Pro, and have been loving every minute of it. I'm using it mainly for work (systems development and graphics design).
1) Salesperson from Apple shop strongly advised against keyboard protectors citing it causes overheating; he recommended regular vacuuming and blowing with compressed air instead. Is this true?
2) Will I see a noticeable performance increase with a 7200rpm HDD? Will a larger capacity and faster spinning speed of 7200rpm degrade battery life? How about heat issues?
3) I'm thinking of getting a matte screen protector to reduce glare and reflection. Will the matte screen degrade image quality and brightness. I seen several sellers (from HongKong) selling cheap ones at US$6 to US$9 with shipping on eBay, are they safe to use?
Here is one such example [URL]

(ex: Working with Core Data, Implementing Push Notification). Certain videos appear to download but when I try to play them, the download starts again. I have "downloaded" the same video 5 or 6 times, and it still won't play.
Other iTunes video downloads from iOS Development Resources work without any problems (ex: Ingredients of Great Apps).
Specifically: if I am in iTunes, and navigate to iTunes U, then select the iOS Development Videos category, I see a list of all the videos that are available. If I click the little "Get" button for many of the videos in the list, the download process seems to work perfectly (I see the progress of the download in the header section, and it all looks normal). However, as soon as the download is complete, the "Get" button reappears and the video listing looks just like all the other videos that have not yet been downloaded. If I attempt to play the video (select it, and click the Play button) the download starts all over again. I have found one video that actually downloaded, and can be played.
Is there a setting that controls this behavior? I haven't been able to find it.
Info:
MacBook Pro, Mac OS X (10.7.3)

Here is the Wired Article. This is big, especially the part about simultaneous releases for future titles. They have even ported the development tools. I also have thought about the rumors of an HDMI equipped mac mini. Think about playing steam games on your big screen,

I see the numbers of everything from Core 2 Duo, to the slightly faster and cooler Core i3, to the supposedly faster core i5s and i7s. The benchmarks go up accordingly, but I found this does not always equate in a faster experience on most tasks.
Here's my experience so far on processor upgrade:
In one computer trade school re-certification class I am in, we are working with Windows Server 2003 on a Quad Xeon platform and it's incredibly slow.
But in a previous class we had the previous generation server edition on older Xeons, and while not fast, it was much better. On paper the newer multi-core Xeons should have made a difference, but could 2003 server software be that much more bloated than the previous Windows server edition that it would stall like that and make us wish we had the older setup?
I am going to try out the Adobe CS lab and put the new high end Dells to the test there and see if they work better than when we had an older CS version on older Xeon equipped Dells.
I don't know if this is something to do with Dell, or if Apple's increasing processor bumps/generations are going to similarly not make a difference in the speed things appear to go at, whether it's Adobe stuff, server stuff, or anything else that needs power.
I know somebody who plans on a Core 2 Duo, i5 or i7 MBP and I was wondering if the higher end processor is worth it in that case (iMovie being the main program of use).

What do you think is the most probable future BTO graphics option (eg. for the Nehalem generation) Mac Pro?
I would like to add one of the two new ATI cards (HD 4850 or 4870) in my mac pro to use in Windows.
I would like to replace the 2600XT completely and flash the new card for mac once there will be a version with an EFI-ROM (which probably will happen sooner or later, like the 3870 now) and therefore I want to get the card which is more likely to appear as mac version in about a year.

I have an opportunity to get a single 3.0 GHz quad core Clovertown.
Should I go for it? There's no advantage to having two cores in two sockets versus having four cores in one socket, right?

is it even possible to upgrade an old dual core powermac g5 to a quad core or even an 8 core.
I have a dual core one and i really need to upgrade to a quad or even 8 but it is so expensive to buy a whole brand new one and i was wondering if there was a way to just get a new processor and more ram or what not.

So the older Mac Pro's from 2008 have 2 2.8ghz Quad Core Intel Xeon processors, without hyperthreading, for a total of 8 cores, and the top of the line iMac has a Quar Core i7 2,8ghz with hyperthreading for a total of 8 (virtual) cores.
With the ghz being the same but less "real" cores, but probably newer CPU architecture, which CPU will actually be faster?

There's a lot of people wondering if the 13" MBPs would have been a lot better with a Core i3 processor, but everything has been just hangups over perceived old vs. new technology, and really the only thing the Core i3 adds is Hyper-Threading, but it doesn't have Turbo Boost, which helps the Core i5/i7s tremendously. Let's compare using Geekbench since it is cross-platform and one of the few available sources of info...
Core 2 Duo P8600 2.4GHz (~3362)
[URL]
vs.
Core i3 330m 2.13GHz (~3472)
[URL]
Core 2 Duo P8800 2.66GHz (~3700)
[URL]
vs.
Core i3 350m 2.26GHz (~3680)
[URL]
As you can see in both cases, the difference is pretty minimal indeed, and in single threaded applications, the C2D will easily outdo the Core i3 which lacks Turbo Boost and runs at lower clock rates.
And you get a 320M instead of Intel HD graphics with the new 13".
The Geekbench results from the old 15/17" to the new 15/17" are quite an order of magnitude better.
So unless people are expecting Core i5 processors in the 13", sticking to the C2D was actually a good decision, and given the differences between 2.4 and 2.53 isn't so large, one is far better buying the base 13" and then putting the money saved towards a good 7.2k HDD or SSD.
Note - I took averages of the 32-bit numbers and added them.
Note 2 - The C2D Pxxxx are 25W TDP processors, which are more efficient than the Core i3 which are 35W TDP processors. Less heat, better battery life from C2Ds.

I've been debating whether or not to upgrade my 3 year old 15" Macbook Pro that has a 2.2Ghz Core 2 Duo (Santa Rosa) to the new 13" 2.4Ghz Macbook Pro. FYI... My current system also has 4GB of RAM. Since both systems are Core 2 Duo, what kind of speed bump am I going to see? Would this be a substantial upgrade?

Does anyone think Apple will release updated notebooks any time in the near future? I know anything we come up with will purely be speculation, but sometimes Apple tends to follow trends. My 17" i5 MBP was just replaced with a gift card, and I'm wondering if I should wait for a bit (Apple had a Mac event in October to announce the unibody) or go ahead and get what I want now. I suppose I can always sell it later if something THAT much better is released.

The ivy bridge processors are coming out soon (or may already be out). I have heard that macbook pro 13" models might be able to use the new processers due to their lower energy useage. I presume that I will be able to take my mac to an apple store and have it installed. Is this information true?
