CoreImage quality on the new mini?

I'm curious about the image quality of the GMA950. I finally got to play with the Core Duo mini (stock config) at my local Apple store.
I was able to play 1080p h.264 clips from the Quicktime site, though I did see some frame-dropping (perhaps due to the 512MB of RAM). 720p clips, as already established, played beautifully. Everything I tried seemed notably snappier than my own 1.42GHz G4 mini, of course.
I did see a weird blurring of the widgets during the ripple effect in Dashboard. (Steps to reproduce: drag the Dictionary or any other widget with text off the 'shelf' into the Dashboard, watch the 'ripple.') Until the ripple/bobbing effect ends, the text on the widget is blurred. As soon as the eye-candy effects are finished, the widget looks perfectly normal and sharp. I walked to an iMac 17" and an iMac 20" to compare, and there is no such blurring of the text during the effect. It just looks like the normal widget, surrounded by the ripple and appearing to bob up and down on a water surface.
Has anyone else observed this in-store or at home? If so, why might this occur? (Driver issues? Speed/performance of the GMA950? Shared memory performance?) I'm mostly curious about this because the quality of CoreImage rendering seems relevant as some developers begin to build image editing applications that make use of it.
Mac mini G4 1.42GHz   Mac OS X (10.4.5)  

That is normal if you have font smoothing enabled in the Appearance Preference pane. The ripple animation was most likely coded to disable the smoothing (or vice versa) until the ripple animation was done making eye candy. The GPU/CPU then doesn't have to try to smooth the ripple (which in effect is unsmoothing the text, no?)
I've been using my Core Duo mini for a few days now and am very, very happy with the graphics in terms of quality and speed. It compares very favorably with my older dual CPU G5 PowerMac which has a PCI-X dedicated graphics card and VRAM.

  • Will the new Mini do Core Image?

    I am waiting for the Mini upgrade. There already has been a silent upgrade where these Minis don't have CoreImage compliant graphics cards - which is ridiculous.
    So, in the end when there's the official upgrade. Will the new Minis be able to do Core Image?

    Sorry, but no one outside of Apple knows anything about future product releases. Anything anyone here would post would be pure speculation which isn't allowed here (the Discussions are for technical support on existing products). There are a number of rumor sites which you can read, but as to whether any rumors they report have any validity, your guess will be as good as ours.
    As to the currently shipping Mac mini that reportedly has some minor feature bumps, it apparently still has the Radeon 9200 and so still will not support Core Image.

    I have a new ipad mini that I need to activate but I need to get the data from my old ipad 1 and install on the new mini.  I have a itunes acct and also icloud acct.  How do I back up the ipad 1 data and then activate the mini.  I assume I will need to transfer the sim from the ipad 1 to the mini.

    That depends on what you define as "good quality".
    Honestly I'm not able to find that model on panasonic's website to find out if it is 720p or 1080p, I suspect it's only 720p.

  • Will the Airport from the new mini work in the old mini.

    I have a MacMini (Intel 2008 model) and I don't use the Airport in it. I want to remove the Airport in that mini and install it in my old MacMini (PPC 2006 model) which doesn't have Airport right now it has a usb wireless stick. I gave that old mini to my mother and she keeps forgetting that the sick is for her internet and removing it. it will also free up that usb port since right now there is no free usb port. Will the Airport from the new mini work in the old mini. I'm not afraid opening them I already installed ram myself in both.

    I assume the old PPC you have is a Mac Mini 1.42GHZ or 1.5GHZ G4 from 2005/2006, which should have shipped with AirPort Extreme and Bluetooth 2.0+EDR pre-installed. What happened to it?
    Anyway, both Mac mini models support Airport Extreme cards, but looking at the repair guides from ifixit.com, the Airport extreme cards look to be different in size.

    For the PowerPC G4 model here is a guide on installing the Airport card: http://www.ifixit.com/Guide/Repair/Installing-Mac-mini-PowerPC-AirPort-Extreme-C ard/271/1

    I don't think they would fit, but Good luck.

  • Does the new Mini support DVI DL?

    I may have missed this question, but:
    The new Mini has a Mini DVI port; does the Mini support DVI DL?
    Pete F

    The only way the new mini can support a DL-DVI display is through the Mini DisplayPort using the $99 Apple Mini DisplayPort to Dual-link DVI Adapter. The actual DVI port on the mini is single-link only.

  • Can I anchor the new mini-player to one screen while keeping iTunes in another on iTunes 11?

    I like having my main iTunes window on another screen while I'm browsing so that it doesn't distract me when I'm working. But I like the new mini-player & I ilke the fact that it notifies which song is playing each time it skips to the next one. So what I'd like is to keep the mini-player anchored to one screen (on Mountan Lion) while keeping the main iTunes window or the album artwork window in another one where I only need to go when I want to interact with iTunes in more detail. 
    This way I can keep the mini-player tucked away in one corner while I browse & I have quick access to the controls & the song info if I need it without having the full screen there. I know that I don't need to have the main iTunes window open all the time & I can simply Option-Command-M to toggle between the 2. But I'd like to have (if possible) the main window open as well on another screen. I have dragged only the mini-player to another screen but iTunes is anchored to the other one (via the dock options) so when I restart iTunes, both players (main & mini) open in the 2nd (non-browser) screen by default.

    Thanks for the replies. The only problem with this solution is that any time I restart iTunes, it'll revert back to normal settings and both will pop up on the same desktop. As opposed to when you anchor it to a particluar desktop so that it open there not matter where you are when you launch the software.
    I realise as I nitpick over this that may not be a very important issue at all But I just hoped there might be a solution to it. Thanks anyway.

  • The new mini keyboard + volume key or F12

    I just got rid of the clunky black keyboard that came with the computer for the new mini keyboard that Apple offers. On the old keyboard the F12 functioned as the volume which it is set up for. Since attaching the mini keyboard the F12 functions as the Dashboard which it is NOT set up for. Is there no way to change this? All settings are same as original keyboard.

    Go to Sys Prefs/Keyboard/Keyboard Shortcuts/Dashboard & Dock. Is the Dashboard box ticked?
    Yours could be different because I have no Leopard kit to check.

  • Can the 30" monitor run on the new mini?

    Can the 30" monitor run on the new mini and is the new mini more powerful/faster than my current original 20" iMac intel duo?
    Thanks in advance for everyone's feedback!
    PS. I know the 30" is due for a refresh and would wait....

    You would need the mini-DVI to Dual-Link DVI adapter, but the 30" would work with that up to it's maximum 2560x1600 resolution.
    However, while the new mini will be a little faster than your existing 20" iMac (assuming by 'original' you mean the 2.0GHz 'early 2006' model), it's not going to offer you a significant performance boost. The mini would offer you greater maximum RAM (4Gb instead of your current 2Gb limit) and has a significantly faster bus and greater L2 cache, and it has 11n wifi rather than your existing 11g, plus a number of other minor enhancements, but you need to consider whether the benefits in terms of better performance and greater flexibility of buying this system, and the display to go with it, are sufficient to justify the costs.
    Much may depend on which software you are using, or plan to use. If you are habitually running legacy software which needs Rosetta, and often need more than one such application open at a time, your maximum of 2Gb RAM may be limiting system performance overall by quite a bit. A mini could help significantly simply by allowing you more RAM. Alternatively, if you are running little more than basic and common applications such as web browsers, email, etc, and have just 1Gb RAM, you might find that a better investment would be to increase the RAM in your iMac to 2Gb, and keep using that for a while longer - perhaps while you decide exactly what your future needs are going to be and thus which hardware is best suited to meet them.
    Alternatively, if you are just feeling that it's time for the iMac to retire and you want a new system, the new mini looks to be a very credible choice for a wide range of users - and pretty good value too!

  • Transferring programs to the new mini

    I have purchase a new mini and want to transfer programs from my older MacPro before recycling it. Problem is, it's 4 yrs old and I have run upgrades via downloads and no longer have discs - but then again the new mini doesn't have an optical drive...so how do I do this?

    A 2008 or even a 2006 Mac Pro should still fetch a pretty good price used. They are hard to come by here and actually the 2008 is probably still worth as much or more than a new Mac Mini. If you don't mind sharing your general geograpic location, (no pressure) I'm here in Califorina and have been looking around for a used 2008 Mac Pro for sometime.

  • How is everyone finding the video quality on the new appletv?

    I had the old 40GB appletv and got the new one yesterday. To me the video doesn't look as good. Getting a full signal, using the same HDMI cable and playing the exact same video files as before I am finding this on everything from netflix(comparing this to my xbox360 or PS3 actually) to my own video and movies and podcasts ect. Am I just being paranoid or is the video just not as good?

    I find the ATV2 to be significantly lower video quality than ATV1.
    I have an Mini with an iTunes library I use to stream to my several ATV1s with many movies and TV shows. My "Man Cave" has a Denon 5 HDMI 1080p switcher, with a Mitsubishi 1080p projector on a 110" screen. After doing many A-B comparisons using the same media streaming to both ATV1 and ATV2 in this room, I find the video quality to be significantly lower for the new ATV2 compared to ATV1.
    I'm a fan of all things Apple, but I'm really disappointed with Apple's decision to dumb down the ATV2's resolution to 720p, - it REALLY shows on a big screen.
    AND, I'm ready for Apple to update the ATV1 software to support Airplay - PLEASE!!
    Thx to all who posted on this thread...

  • The new mini ipad

    Hi, i am new to tablets and want to buy my first one, (7''ish). I'm considering the new Ipad mini coming out because it's one of the few that have back facing cameras for stills and video. But the difference between the 16Gb and 32 Gb for storage is quite high. I like to back up all of my music, videos and photo's ect on to pen drives rather than a exterior hard drive. My question is; by using the lightning to USB connector would it be possible to connect the Ipad mini to a pen drive on the move and read & write to it for extra storage and even stream video to and from it?
    Hope this doesn't come across as a stupid question as i'm a bit of a novice with hand held devices.
    Many thank's.

    With the full-sized iPads you've only been able to use the camera connection kit to copy photos and videos from SD cards, cameras, and some flash drives (a lot require too much power) to the iPad's Photos app (and the card/flashdrive needs to have a DCIM directory off its root with the photos and videos underneath with 8 character filenames plue extension) - you haven't been able to copy content off the iPad with it nor to copy music to the iPad with it. I doubt that that will change with the mini-iPad.
    There are a number of wifi-enabled drives now on the market that allow you to stream content to the iPad (and I assume that they will work with the mini-iPad) e.g. Seagate GoFlex Satellite etc.
