ATI radeon X1900 vs ATI Radeon 9650

Hi there,
I was wondering if anyone could help me find out if my actual graphic card (ATI Radeon 9650 256MB) is my best option running Final cut pro studio and other graphics software or is there something better like the (ATI radeon X1900).
Any help would be greatly appreciated.
Thanks!

Hi,
you can not have ATI X1900 G5 card for your computer. This is a PCIe card and you have AGP - but I suppose you know that.
So, the best option for you (and better than Radeon 9650) is ATI X800XT or NVIDIA 6800 Ultra DDL. They are similiar (in performance) cards - it depends on the test. Check this sites:

Hope it helps,

Crash with ATI Radeon X1900 XT and second HD display (DVI) ?

hi ! i have a realy tough one for you guys : since 3-4 days i've been getting this realy strange (and scary!) kernal panic screen / crashes / freeze with my macpro dual 2.66 with ati radeon X1900 xt.
the crashes keep coming while doing extensive work (video converting, renders) or just letting the macpro running doing nothing much all night long...
now this is what i found for now : if i disconect my 2nd display (samsung syncmaster 2493hm HD in DVI 1080p) it seem to be stable. when i reconnect it sometime it can run again with this 2nd display for a while but when i leave a render all night long the next morning it will be frozen, nothing on screen (all black).
after rebooting it get this crash report from the system :

What is a good replacement for the ATI Radeon X1900 XT on a late 2007 Mac Pro

I recently took my late 2007 Mac Pro to the Apple Store because it was running quite loud. They diagnosed the problem as the fan on the ATI Radeon x1900 XT video card. Whie the card works fine otherwise, I was thinking of replacing it. I noticed some online recommendations that I need to upgrade to perhaps the Radeo HD 4870 if I want to install FCP X on this machine. I do use the Mac Pro for video editing, but haven't switched yet to FCP X. Anyone have a suggestion on a replcement video card that will work both on this machine and will be compatible with FCP X.
Thanks for any advice.

GPU enhancement issues with ATI Radeon X1900 XT

Upon startup, PS CS4 turns off GPU enhancements and displays the following error message:
"Photoshop has encountered a problem with the display driver, and has temporarily disabled GPU enhancements. Check the video card manufacturer's website for the latest software."
Problem is, according to all the research I've done, PS should be perfectly compatible with my Radeon X1900 XT card. To further complicate things, ATI does not appear to have driver updates for Radeon X1900 cards for Intel Macs on their website. Even a Google search doesn't seem to bring up any sites with the drivers. It's maddening!
Is anyone having similar problems, or can anyone offer advice? All Adobe and Apple support seem to recommend is updating my drivers, but of course that doesn't seem possible. Thanks!

I'm having a slightly different problem, but it fits in with what others are saying. I upgraded to CS4 the other day, and starting that night my system (a Mac Pro with the Radeon x1900 card) I have had issues with my display - that is, sometimes the display won't work after waking from sleep. The display is a 23" Cinema.
The rest of the system is fine (I have a laptop so I can peek in and control it remotely), and everything is just as I left it. The display itself responds to being turned on and off using the power button on the side (that is, the tiny light on the front turns on and off...). But the screen itself is pitch black, off entirely.
I took out the video card and it was, indeed, black on the intake with fine dust, so I cleaned that as best I could. That did not solve the problem, however.
Pull the plug to my desktop and plug it into my laptop, and it works just fine. Plug it back into the desktop...dead. The only thing that seems to fix it is shutting it down for a time. I don't know how long is required but it's more than a few minutes (so it's not a simple reset) and it's only been a few days and so far I've just gotten frustrated and left it over night - so it certainly could be related to cooling down.
Seems like Adobe is the culprit as the problem has *never* happened before, and has happened every day since the very day I installed CS4. I'd be reluctant to believe it...if I hadn't spent hours just upgrading to CS4 (I won't go into the legendary problems which plague Adobe's installers).
Given that when I bought this system a couple of years ago this was one of the few video cards I could choose, and it's the high-end of the bunch, there must be a lot of folks out there with this set-up plus CS4...
Sounds like the suggestion is to inhibit performance in CS4 so it doesn't fry my video card? I am running Temperature Monitor, but it doesn't show me that particular stat...

Nvidia GeForce 7300 GT and ATI Radeon X1900 XT

I have a Mac Pro 2,1 running 10.6.1 and BootCamp.
I had a Nvidia GeForce 7300 GT video card in it and it ran well under BootCamp.
I installed a ATI Radeon X1900 XT.
Under BootCamp the 2 cards seem incompatible, with an error message that the driver on the Nvidia card has been disables due to an incompatibility with the other card.
Is there a solution for this?
If I wanted 2 cards inside would they both need to be the ATI's or Nvidia's?
Thanks

Hi I would maybe get a Apple Upgrade Kit the GT 120 is 512MB's & dose not use all 16 lanes as it like to make you think & will work on 2006 Mac Pro's at $149.00 I would say if you just want more displays get two & eBay your old cards. Please know if you game you will want more power but if only for more displays this 1 slot card is great.

NVIDIA GeForce 120 or ATI Radeon X1900... which is better?

Hi-
I currently have the ATI Radeon X1900 graphics card installed in my Mac Pro 2.26 Nehalem. I'm not having any issue's with the card except that the fans turn On quite frequently, and they're a little loud.
I'm not using it for any games, etc... My primary use is with Pro Tools (a music DAW application).
The ATI Radeon X1900 is running a Apple 30" display and a Sony Bravia 46" LCD.
If I replaced the ATI Radeon X1900 with a NVIDIA GeForce 120, would I be asking for trouble?
Thanks in advance.

If I replaced the ATI Radeon X1900 with a NVIDIA GeForce 120, would I be asking for trouble?
If your Mac Pro came with ATI Radeon X1900, then it needs a card with EFI-32 firmware. The NVIDIA GeForce 120 has EFI-64 firmware, and won't work in the pre 2008 Mac Pro. The only upgrade for early Mac Pros is the ATI Radeon HD 4870

After Effects 7 with ATI Radeon X1900 XT

Hi everyone,
I use Adobe After Effects 7 a lot and I'm not happy with my current machine (PowerPC G5 2x1.8GHZ, 2GB DDR SDRAM, ATI Radeon X800 XT), it is too slow to work smoothly when I have several layers and effects going on. Previewing the work on the timeline (OpenGL or Adaptative resolution) is painfully slow and takes on my nerves. I believe this is mainly due to my graphics card, and the fact is not 100% compatible with OpenGL on After effects.
I'm ready to upgrade with a Mac Pro 2.66 GHz Quad Xeon with ATI Radeon X1900 XT, but only if I'm going to enjoy a real improve with After Effects 7, as this is my main editing application right now.
Does anybody have experience with this configuration?
Thanks in advance for reading and replies!
PowerPC G5 2x1.8GHZ Mac OS X (10.4.7) 2GB DDR SDRAM, ATI Radeon X800 XT

I have this configuration, but sadly have had no time to play around with After Effects. AE's realtime playback capabilities are limited (especially when compared with something like Motion), so you're probably still going to be rendering to RAM a lot. I believe the OpenGL support is for things like anti-aliasing, blur, and blending modes -- so a faster video card may not automatically equal huge performance boost across the board. Four Xeon cores and a lot of RAM will help it a lot more (see exception below).
Also, AE 7 still has to run under Rosetta which results in a slower performance than if it was native. Also, be aware that there is a limit placed on all Rosetta processes that do not allow them to address more than 1.5GB of RAM combined. This will most likely limit your render speed and preview lengths. See this thread on Adobe's forums for more info:
http://www.creativecow.net/articles/jonesgraham/AE7_on_IntelMacPro/index.html
EDIT: The above link was to the performance comparisons, but not the original Adobe forum thread. Here it is:
http://www.adobeforums.com/cgi-bin/webx/.3bc2401b
However, if you read the thread, and follow the link in it, the author is seeing huge performance gains with AE7 on his MacPro 3GBs over his old dual G5 4.5GBs.
So most likely, you'll see a performance benefit from upgrading. And when an Intel native version of AE ships, things will really fly.

ATI Radeon X1900 worth it for only FCP and Color?

Hello,
I've been looking around these posts for a while and I can't seem to find this specific answer, so I apologize if my question has been asked already.
I am looking to purchase a MacPro tower. I don't use Motion. I don't play video games. I don't need 8 zillion giant monitors. I intend to use the computer mainly for Final Cut Pro 6.0 and probably a fair amount of Color as well.
With this being the case, what are the benefits of the
ATI Radeon X1900 XT 512MB Graphics Card, over the
NVIDIA GeForce 7300 GT 256MB Graphics Card? Is it really worth the money? I've seen some posts that say you won't see a difference in FCP, but is this also true for Color? And if so, what exactly will the difference be?
Thanks,

Here's what they said at the Color board...
With anything less than an ATI x1900...you may experience issues such as lack of realtime playback, missing support for 10-bit images and 2K frame sizes, no float support for your grade settings.
For this version of Color, ATI is the way to go. I wouldn't go so far as to say an Nvidia card gives you a crippled version of the program, but it's close.

Please help: what options do we have other than ATI Radeon X1900 XT

I think my video card (ATI Radeon X1900 XT) is about to die and I'm trying to figure out what to replace it with. (I'm on a 1st gen MacPro, still on Tiger).
What I can't easily figure out from this site, however, is a list of alternative cards I could purchase that will fit in this machine. I gather from the ratings that the ATI X1900 has failed for just about everyone that has used it intensely. And I'd like to avoid buying the same one that is about to fail for me now, but how can I tell what my alternatives are and if they will fit in the slot and/or be compatible with my machine?
I have been to the Mac Pro spec area, and it lists these as the "build to order" options:
* ATI Radeon X1900 XT 512MB (two dual-link DVI)
* NVIDIA Quadro FX 4500 512MB (stereo 3D, two dual-link DVI)
* Two NVIDIA GeForce 7300 GT 256MB
* Three NVIDIA GeForce 7300 GT 256MB
* Four NVIDIA GeForce 7300 GT 256MB
are those the only cards I can choose from? Are there any other better options?
Forgive me if I sound like a totally idiot. I'm just trying to learn...

You should visit Bare Feats and see the various reviews and benchmarks. You have several options now available besides the ones that came originally with your model. There is now an NVidia 8800 card in a version for pre-2008 MPs, the ATI 2600, and the new ATI 3870 just released. You can learn more at Bare Feats and by searching the MP forums.
You have posted this topic in the MacBook Pro forum which is the wrong forum for your question.

Signal Problem MacPro 1.1 w/ATI Radeon X1900 XT

Before I run out an purchase a new video card wanted to run my issue by the forum. I have a MacPro 1.1 (early 2007) with a ATI Radeon X1900 XT card. When booting up recently my screen is blank, no signal. If I switch video ports it fires up.
Is this a video card issue or something else with the OS (running Mac OS X 10.6.6 (10J567))?
Would appreciate a little insight from the forum.
Thanks,
Koyangie

1. There was a replacement program that ended 1/31/2011 for some X1900
2. Any owner by know should have known and been doing a good deep cleaning for dust, and upping the system fans a tiny notch (900 rpm is quiet but more efficient) to keep more air circulating
3. While you can't directly measure GPU temps, you can with other sensors
4. Do you hear the video card fans or system fans working hard?
Poor design with the cooling chamber on X1900 made it a dust magnet and headache.

Need Power Connector Cable for ATI Radeon X1900 XT

I need the 6pin power connector/cable for my ATI Radeon X1900 XT to work with my Mac Pro.
I can't use the card as I lost the small cable pior to installation and now I can't find one anywhere.
It is the 6 pin cable that connects into the Radeon X1900 XT and the other end into the Mac Pro motherboard.
Can someone help me?
Thank you

Worst service ever at the local(Canada) Montreal/Laval Apple Store........''go ask ATI or call Apple, etc....''

Brandnew 8-core MacPro and ATI Radeon X1900 xt

I had this quadcore MacPro with an ATI Radeon X1900 XT and now I am switching to a newer octo-core MacPro.
I managed to install the card into the computer case. But alas, i don't see anything on my screen...
System Profiler discovers the card but gives it an generic name "Display" with Vendor ATI and DeviceID 0x7249.
But no "displays" found attached to it, which is b.s.
Please please don't tell me i cannot use this graphics card in the octo-core MacPro?!

I am surprised .... I don't have (any ideas), so I don't know for sure
You know, that doesn't help or further things and puts out false ideas that there even might. Then I'll hear "but I read somewhere something."
Apple changed the firmware on 2008. That is well known and pretty obvious, and graphic cards have to follow suit.
Nvidia doesn't seem to know or follow ATI's path of using a "hybred" (for want of better term) EFD? ROM that works across EFI32 and EFI64. Been explained over and over, or if not explained, given as cause to why.
At least we have a few years before EFI128!
NVidia GeForce 7400 gfx card
Now that is very elusive.
The 7300GT works only in 2006-7 Mac Pro, which were dual processor / dual or quad-core, but all used EFI32; 667MHz FBDIMM; had 1333MHz front side bus; PCIe 1.0/1.1 (but not PCIe 2.0 that came out in 2008).
And with brand new 2009, DDR3, you graphic option is really between GTX 285 and ATI HD 4870 - forget the GT120 even as a viable option for most.

Can I put two ATI Radeon X1900 XT's into a MacPro?

Hi
We've just bought a MacPro, with 3 NVIDEA 7300 cards. Sadly it seems the 7300 does not support the apple DVI-Video adapter. Our system requires three dual link DVI ports supporting the adapter, so on face value we should be able achieve this by removing the 7300's and installing two ATI Radeon X1900 XT's instead.
The question is is it possible to put two ATI Radeon X1900 XT's into a MacPro? Has any one done this? or indeed does anyone know how to get the 7300's to recognize a DVPAL device such as video projector or analogue video monitor?
Cheers
Nick
MacPro Mac OS X (10.4.8)

PCI-E (Peripheral Component Interconnect-Express) is a newer implementation of PCI which uses a much faster physical-layer communications protocol than older PCI bus architectures.
Rather than using a bus as PCI did, PCI-E uses dedicated, unidirectional, point-to-point connections known as "lanes" to communicate with PCI-E devices.
The Mac Pro features four PCI-E 16-"lane" connectors on the main logic board. In PCI-E, these are known as "x16" slots. These can be used for PCI-E-compatible cards, like the ATI Radeon card that is available as a configure-to-order option in the Mac Pro.
PCI-E cards will work in slots that are at least as large as the card is. This means that the "x16" slots in the Mac Pro computer also supports "x1" and "x4" cards as well. However, all four slots cannot simultaneously support four cards that implement the same lane configuration. Only one slot actually has 16 lanes going to it—you can put a x16 card into a slot that is only using one lane and it will operate properly, but it will operate more slowly than the same card in a x4, x8 or x16 slot.
The Expansion Slot Utility, located in /System/Library/Core Services, allows you to configure the PCI-E expansion slots and how many lanes each slot will support, as illustrated below. This example shows a "x16" graphics card occupying the first slot, and the other slots are configured to support an "x1" card in slot two and "x4" cards in slots three and four. The example shows the other options available. When you have picked the appropriate configuration of slots to support your compliment of PCI-E cards, click the Save and Restart... button to implement the configuration.

Alternatives to ATI Radeon X1900 XT 512 MB

Hi Guys,
I'm pretty sure my ATI Radeon X1900 XT 512 MB graphics card has failed...
I run MacPro1,1 (2008) Dual-Core Intel Xeon with 2 x 23-inch DVI Apple Cinema Displays. Tonight only one of the screens would wake from sleep - the screen in port 2.
I've tried...
1. Swapping the DVI cables, this results in the non waking screen waking and the waking screen, not waking.
2. Tried running just one screen off DVI port 1 and nothing happened, blank screen but power light on.
3. Tried running same screen off DVI port 2 and still nothing happened, blank screen but power light on.
To re-cap - None of the DVI ports work on their own and only Port 2 works when both screens are plugged in.
So... is there any other tests or checks I can do to confirm 100% it's a faulty card? I've unplugged and done the SMC reset.
Secone part to this - if the card is shot can anyone recommend an upgrade to the ATI Radeon X1900 XT 512 MB?
Thanks

You could use a Mini-DisplayPort to DVI adaptor on one of the ports, I would think. Otherwise, you don't have two many choices. You might look for a used ATI 4870, Mac Edition model. It's performance will be similar to the 5770 since the 2006 MP only has PCI-e 1.0 slots so the 5770 can't take advantage of it's capabilities if installed in a PCI-e 2.0 slot.
Other cards that will work include the older Nvidia 8800 GT for Mac. You must be sure with these other cards that you look for the ones that are compatible with a Mac Pro. These were the ones made specifically for Apple. Non-Apple cards will not work unless you have the hardware, ability, and knowledge to re-flash ROMs.
