Lightroom 4 tech specs question?

Lightroom 4 tech specs says it runs on Intel® Pentium® 4 or AMD Athlon® 64 processors. Will it only run on these processors? Or will it run on others like say XEON?

It depends on what your definition of "run" means and what camera file types you will be using. I started using LR1.0 on XP 32 bit with my Canon 300D 6Mp images on a 3.0 GHz Pentium 4 system with 2GB memory. Everything worked quite well right up through LR3 when I bought a Canon 5D MKII 21Mp body. The 21Mp CR2 raw image files brought LR3 to its knees, making it almost unusable. LR4 requires even more processor resources.
I currently use LR4.2 on Windows 7 64 bit with an i7-860 processor based system and 12GB memory and it runs quite well with the 5D MKII 21Mp raw files. There is what I believe to be a small group (<5%) of LR users that are experiencing performance issues with LR4, some on fairly high-performance systems. In some cases attached USB devices (phones, monitor calibrators, MP3 players, etc.) was the cause and removing them has resolved their performnce issues. My best suggestion would be to use a high-performance dual-core or medium to high performance quad-core processor with at least 6-8 GB memory. I suggest downloading the trial copy of LR4.2 and give it a test drive.

  • Want to buy Photoshop Lightroom 4, but the tech specs ask for specific processors?

    Hi all,
    I'm thinking of buying product listed in question, but the tech specs for it says that I need either "Intel® Pentium® 4 or AMD Athlon® 64 processor", but I have intel inside core i5 processor.
    Will Photoshop still work, or are the processors listed on the tech specs just the best processors for it?
    Thanks.

    Those are minimum specs. Your i5 based machine should be fine.

  • How can I get the tech specs of my MacBook Pro?

    Hi - I want to sell my MacBook Pro (to buy a new one). I am one of those people who loves Apple because I do not have to worry about techy things as I had to when I was a PC guy. The problem is that, as a result, now that I want to sell my MacBook, I cannot remember its tech configuration and do not know how to get it!!
    I am sure this question is most silly for most of you. Could someone please let me know how I can get the tech specs of my MacBook? In particular, I was thinking of:
    - OS X version
    - Processor
    - L2 cache
    - System Bus
    - Memory (RAm)
    - Hard Drive
    - Optical Drive
    - Graphics card
    - Graphics memory
    - Video capability
    - Display resolution
    - Expantion slots, etc
    - Ethernet card
    - Wireless card
    Thanks a lot!!

    For the published specs, click on the Support tab at the top of the page, select the "Tech Specs" link, and search for your model of MacBook Pro. For specifics about your system, run System Profiler, which will be in Applications -> Utilities folder on your MBP.

  • Tech Spec's for Mac Mini 2.0

    Hi All,
    Having been a long time user since 1995 of several models of Windows (95, 95SE, XP HE, XP Pro, Vista Home Basic &amp; Vista HP) desktops and notebook pc's, I have never used 'Mac' computers before, (though I DO currently use an iPad 4 and an iPhone 5 and am very impressed with these devices). I have a question as to what the standard tech specs of an Apple Mac Mini 2.0 are supposed to be. On the bottom of the casing of the white 'Mac Mini 2.0' is printed '2x512//120/SD/AP/BT - GBR' after the serial number. Is it possible to find out what the tech specs of this would be from this info?
    The serial # number is YM*******YL2.
    There are also 4x USB ports, 1x 'dvi' port, 1x Ethernet port and some 'other' ports that I don't recognize, below the on/off button at the back of the unit one of which must be the mains power connector. There is also a slot loading optical drive at the front.
    How would the tech specs of this 'Mac Mini 2.0' compare with my current Win Vista HP desktops (Core Duo 1.6Ghz &amp; Core2 Duo 1.6 Ghz, both with 2Gb Ram and Windows Media Centre, but only one of them having a wifi card and a 'Freeview' decoder - the one with Core2 Duo), and is there any point in trying to buy this Mac Mini from my younger brother? (What is it likely to be worth?).
    He also has a previous model of Apple TV which he does not seem to use, which is at least three times the size of his 'new' Apple TV box. Is this 'old' Apple TV item worth having, and what would the specs and value of this device likely be?
    Any answers very greatly appreciated.
    Thanks
    Bob

    Hi BDAqua,
    Wow!, that sure was quick reply. So thanks for the info. Your answer confirmed what I had thought. I WAS going to ask my brother what, if anything, he was planning to do with his 'old' Mac Mini, and 'old' Apple TV, seeing as he has a new Apple TV, and a new 27" iMac, and does not appear to be using the 'old' ones at the moment.
    I think perhaps, I may not bother, and just save up for either my own new Mac Mini or iMac (or a MUCH HIGHER SPEC Intel i7 /Win' 8 PC) when I have finished paying for my iPad 4 and iPhone 5. It was just an idea, since I am so sick of my Windows pc's seemingly needing full destructive recovery every three months or so, that it is doing my head in.
    This is even though I check for and install the update for the Windows OS and Norton Internet Security every single day, and do a full scan with Norton Internet Security, and run Norton Utilities every couple of days, which has NEVER found anything that it has not already removed or quarantined, while PC is in use at other times.
    I guess that is what happens when you (I mean I) try to get by with a 'cheap' PC instead of the one I should have bought.

  • Tech Spec? - Sound compatability Problems

    Sorry all ........ I posted this last week but nobody answered my query .......... could someone help with some SIMPLE TECH SPEC?
    When playing back any of the work which we produce in iDVD in a Home Cinema 5.1 type environment, there are soundtrack incompatibility issues and the result is DVD's made in iDVD playback clicking,spitting & at the wrong pitch!
    Having done a little research with the very helpful Dolby consultants in England, I found that the audio formatt a "standard" commerciallly available movie encoded in 5.1 uses is 16 bit 48 khz ......... however, having scoured the iDVD website, I can't find definitive Audio Spec for the vob files that iDVD resolves in it's final masters. To confirm my suspicions that for some reason Mac chose to use a different standard of their own, CAN ANYONE POINT ME TO SOME DEFINITIVE AUDIO TECHNICAL SPEC?
    Many thanks Richard

    Hi Len
    Many thanks for your input. Unfortuanately my question wasn't what "iDVD likes" .................... I'm having great trouble finding an answer to - WHAT IT MAKES ?
    I'm a movie composer and have started using iDVD to compile showreels of clips from movies that I've scored. So my "source" is actually a series of Quicktime PAL DV movies which have been exported from original masters. The Quicktime files that I drop into iDVD all contain stereo 16 bit 48 khz soundtracks.
    When you play any of my iDVD compiled showreels on a standard stereo DVD player (or even in the Macs own DVD player), they play absolutely fine.
    HERE'S WHERE THE PROBLEM BECOMES A BIG ISSUE:
    A lot of production companies have 5.1 "Home Cinema" type playback systems in their offices, and I've found that when they play iDVD derived stuff back through the 5.1, the resulting soundtrack (ie. my years of hard labour!) is horrid.
    I simply wonder what the DVD's we burn from within iDVD resolve as a sound format when they make the VOB files - because they use a differnent format to the one used by the companies that manufacture commercial DVD's for the worlds motion picture industry? ie. What is the Sample/Bit Rate of iDVD produced DVD's
    Many thanks Richard

  • Apple's tech specs are weird

    I didn't know what forum to put this on, but I'll try this one. I was wondering on which iPod I wanted to buy and I was looking at the iPod tech specs and I noticed that for the iPod nano 8gb can hold 2000 songs and the iPod touch 8gb can hold 1750 songs and I'm wondering what's up with that. Also, the iPod nano 8gb can hold 7000 photos but the iPod touch can hold 10000. I'm just wondering if that they use some sort of compression that differentiates the two.

    I don't know why they are different. But, please keep in mind that those numbers are just ball park estimates and your actual storage will be different depending on how long your audio files are, which encoder is used and the bit rate selected. Same with photos. Also the more songs you put on, the less space for photos. And the more photos, less space for songs.
    So that said, both are in the ballpark of each other in terms of number of songs and number of photos so I wouldn't get too worked up about the small differences. The question should be, is being about to store roughly a couple thousand songs (might be 1500, 1800, 2123, 1901, etc.) and roughly 6000-12000 photos enough for your needs? If you are way below those numbers, then you are all set. If you are right about at that level, you may run out of space and need to be creative on how you load the iPod or think of a larger model. If you are way above that, then look at larger models or just be ready to selectively sync only certain things on at any given time.
    Cheers,
    Patrick

  • Tech Specs for 24" Imac Screen/Comparison

    Does anyone have the actual tech specs for the screen itself in reference to the 24" Imac (response time, etc.)
    How do you think the screen on the 24" Imac compares to this HP 24" monitor?:

    The 24" ALU iMac's display panel is an *LG.Philips LM240WU2-SLB1*.
    According to TFTcentral, it's an 8-bit S-IPS panel. For more specs see:
    http://www.tftcentral.co.uk/articles/panel_parts.htm
    Great specs, but the specs don't say anything about iMac's problems with
    uneven backlighting. The white 24" used the LG.Philips LM240WU2-SLA1,
    and had a gorgeous display -- as does NEC's professional LCD2490WUXi.
    Check the specs, but also check some [24'' ALU iMac screen photos.|http://picasaweb.google.com/TheLooby]
    How do you think the screen on the 24" Imac compares to this HP 24" monitor?:
    [HP w2408|http://www.shopping.hp.com/product/display/display/1/storefronts/RY117AA%2523ABA]
    I don't have a mfgr's part number, but it uses a 6-bit TN panel. Faster
    than S-IPS, but significantly poorer viewing angles. OTOH, it probably
    doesn't have the brightness gradent problems common in ALU iMacs.
    For $75 more, HP's LP2465 and Dell's 2407 have superior 8-bit LCD panels,
    and much better warranties (3-year & 5-year versus 1-year on the w2408).
    I'm sure there are many other good (or better) choices as well, but I haven't
    been monitor-shopping lately.

  • Can I get the tech spec for my mac mini online?

    I am selling my mac mini and need the tech spec as the one's on the Ebay catalog are not correct for this model. There must be a way of entering my serial number but I can't find a suitable site and Apple Support will charge me for asking them!!!

  • Adobe AIR 14  video player app : windows 8+, Mac OS 10.8 &10.9, android 4+ not mentioned in Access tech specs

    We're currently studying to develop a video player app using AIR 14 targeting Windows, Mac OS and Android.
    Access DRM is needed but reading online tech specs (URL Adobe Access - Tech specs), there is no mention of windows 8+, Mac OS 10.8 &10.9, android 4+ support.
    Can you please give us accurate information on that topic ?
    Thank you.

    Hello,
    Sorry for delayed reply.
    Adobe Access DRM are supported on those platforms.
    Basically Adobe Access requirements are same as Adobe AIR requirement.

  • Are the CS5.5 tech specs too low?

    Looking at the CS5.5 Design Premium tech specs (http://www.adobe.com/products/creativesuite/design/tech-specs.html) I wonder how well the software would work if installed on such a computer. The new entry level quad-core i5 iMac for example has a lot higher spec than what Adobe says is required. Is it that Adobe lists the minimum required specs and that what could be achieved with the software on such a computer would be limited?
    For example, CS5.5 programs support multithreading so there should be a significant difference between how the software performs on a quad-core computer compared with a Pentium 4 or even a dual-core processor. The other concern is that it is usual for designers to have multiple programs open at once, like Photoshop, Dreamweaver and Flash. Surely a higher spec computer is needed to be able to work productively.
    Also, wouldn't a screen size of only 12000 x 800 (as listed) be too small to work productively in CS5.5? Programs like Photoshop have many windows that would more than fill such a small screen leaving only an impractical work area.
    Is it fair to say in terms of productivity and what could be achieved with CS5.5, that a new i5 quad-core 21.5" iMac  (1920x1080) would be significantly better and preferred spec?

    Yes, that would be fair. I use Windows most of the time and just built a new machine with an i7 processor and 16 gigs of RAM.

  • HOW TO PREPARE TECH SPEC FOR OOPS PROGRAM

    Hi..
    This is Sri .I Created a Report program in oops. can any one help how to prepare tech spec for this oops report,,can i need to mention Classes ,Methods, ref-classes,screens in preparation of Spec..
    Thanks in advance..I surly reward with points if my prob is solved,,,,,,
    SRI

    Hi Sri,
    Tech Spec is nothing but a document containing some technical information about
    the object you have developed/coded. Normally this should be prepared before you code and not the other way round.
    You should mention relevant classes created / used. If you have created / added some class components like attributes/methods/events/interfaces mention that too.
    You can also mention functionality to be coded in methods of the class. Please understand it is not a replica of your program but some useful technical info that the coder will use to code and later people will use for maintainance purpose.
    It is better if you have some defined template for the tech spec, else just put the info in a structured and readable manner.
    Regards

    Where is the link that says you need a 32 bit processor?  On my MBA, in the past I've ran both Office for Mac and Windows 7 (MS Office) via Parallels (Bootcamp does the same thing).  I chose installing Windows 7 in the 32 bit mode ONLY because I have a couple of other legacy Windows programs that only run in 32 bit mode.

  • Why is the iPad 3 not available? Not even the tech specs!

    Why isn't the iPad 3 available? Not even the tech specs!

    There have been five iPad models: the original iPad, the iPad 2, the third generation iPad, the "iPad with Retina display" and the iPad Mini.
    http://store.apple.com/us/browse/home/shop_ipad/compare
    The original iPad and the third generation iPad have been discontinued. There is not now, nor has there ever been, an iPad 3 so if you are searching for technical specifications look for iPad (3rd generation).
