2600xt?

really?? Are you that serious?? then why does it say PRO instead if XT?? I'm getting a little hyper right about now:D:D

We don't know why it says pro under os x, but clearly from ati's point of view it's an xt. You can even download xt drivers under os x and they'll boost performance about 10-15%.

EDIT: It's really more of a hybrid. The core chip is the same as in a moblie xt, but the clock speeds plus memory are that of a pro.

Really :)
In your Windows partion the systems profile will give you the correct type.

It also appears that iMac 2.8 duo core extreme users do not find the word "extreme" added in their OSX system profile, but when booting in the Windows partition it is correctly displayed.

MAMA!!! This is awesome news, do you have to download drivers manually? and how? it wont let you download PRO drivers? so your seriously telling my i have 512mb of vram on this baby?

Erm no, sorry to disappoint you, not 512MB, it is under-clocked and has the memory of the 2600PRO, just like Muncher told you.
But you can manually download the drivers of the 2600XT and this will increase the speed quite a bit.

I don't think you have 512mb of vram, but I'm not at my mac right now so I can't tell you for sure. What I do know is that the best way to to things (in my opinion) is to download the latest catalyst drivers and the mobility modder in windows, and follow the instructions on the modder's page. It is a noticable increase in performance.

ok, so let me get this straight, my imac has 256MB of vram, the core chip of an XT, like the man thing and everything, but the clock speeds are as slow as the PRO, is that right? and what happens if i download PRO drivers and updates? would it say it's not compatible? and where can i get the drivers and updates from

Pros and XTs are identical save for the core clock speeds and memory speeds. ATI never made a Pro version of the Mobility 2600 so Apple downclocked a Mobility XT to desktop Pro speeds and called it a Pro.

Ok, either way, im happy, it's great to know i have something better than a PRO, but not exactly an XT, but what happens if i download PRO drivers and updates? would it say it's not compatible? and where can i get the drivers and updates from?
 
So which method should I use to install the drivers?

Use the Mobility Modder or

Use this method

If someone could inform it would be great! :D
 
But heres the thing. the 2600 series are in the desktop series, which is the RADEON series, i guess it makes sense that a huge, bulky video card wouldn't fit in an imac.:rolleyes:

And the iMacs use a Mobility Radeon 2600. Its six of one, half a dozen of the other. There is increasing less difference between desktop and laptop parts as far as video cards go these days, particularly in the low-mid end of things. Clock speeds and memory capacity are about the only distinguishing factors.

Very confusing, but I think i get it, the video cards in the imac is the 2600 XT, but has a clock speed of the PRO, and RAM of a PRO. and is also a mobility model, either way, im happy, I am not sure if I am thinking correctly, but I believe the whatever video card in the imac is better than the 2600 PRO radeon for desktop, not mobility
 
it's not an XT

It's not an XT, nor is it a hybrid card as some have claimed. If you install the proper ATI drivers it shows up as what it is - a regular 2600 Pro. As nice as the XT would have been the Pro still plays Bioshock and Crysis just fine so I don't care so much.

It is an XT but it is a Mobility (laptop) chipset. There is no Mobility variant of the Pro but it runs at desktop Pro speeds, hence the moniker. The chip id has been confirmed as a Mobility XT part. ATI drivers don't install out of the box on XP or Vista because ATI does not provide laptop drivers but the desktop XT drivers work just fine. Again, the only difference between XT and Pro is clock speed and VRAM.

Does anyone know if it uses DDR2 or DDR3 RAM?

DDR3

bluedoggiant said:
well, at this point, im confused, but i can tell you that the XT takes ddr3, and the PRO takes ddr2

Pro's can take DDR3 as well but many are configured with DDR2, hence the poor performance results being bandied about for 2600Pro cards.

Hi, just a query as I'm new to all this 'under-clocking' and 'drivers' stuff. :confused:

If I download these 2600PRO (XT) drivers for my 24" 2.8GHZ iMac and install them thus adding speed to the Graphics Card does that mean that the iMac has to work faster and if so is there a chance that the fans won't be able to handle the heat and cause a major issue with my Mac?

Is this why it is under-clocked on the Mac due to heat reasons?

Thanks
 
Drivers under OSX and VMWare

I have 2 related questions:

1. Is there a way to install the XT drivers on the OS X side (Leopard) to take advantage of the superior graphics power under OS X or do we depend on Apple to improve the Mac drivers?

2. Would you have any performance improvement when running XP in a virtual machine (VMWare) or do these solutions use their own graphics drivers?

Thanks for the insight,
D.

1. There are no XT drivers for Apple, otherwise everyone would be using them. Windows drivers are not compatible (and neither are Linux drivers).

2. VMWare/Parallels use their own graphics drivers/card to run. Usually the card emulated was a S3 virge (or something like it), nowadays I imagine the VM's that can draw 3d graphics use a more recent card for emulation, but nothing too new.
 
Thanks for this quick answer. This means we can only profit from the updated graphics drivers under Bootcamp running Windows XP (or Vista?).
