The driver ATIRadeon9700 is somewhat generic, as it covers more than the 9700 card. As this tip is useful, it is not specific, as on my Power Mac G5 first generation 2x2GHz with a ATI Radeon 9600 (not XT, Pro or anything) this driver is shown as loaded (in Apple System Profiler) The more specific info is shown under Hardware, PCI/AGP Cards. You should see at least one entry to the right with the cryptic info about the GPU on your card. Mine shows as ATY,RV350 ATY of course means ATI. The RV350 is the Radeon 9600.

The codes are as follows:

I compared the performance of three cards using CINEBENCH 2003. (http://www.macgurus.com/forums/showpost.php?p=75651&postcount=161)

Skip 9200. Reviews of performance are poor. Useful for "palettes" and such on a 3rd monitor when you have to use PCI. Users of B&W G3s find it isn't any better really than the older PCI Radeon Mac.

Your best low cost choice Radeon 9000 Pro if can't use the OEM 9000.
Flexible Dual Monitor Support
Double your monitor work space. To provide for flexible display options, the RADEONª 9000 PRO Mac Edition comes with an ADC connector port, a DVI-I connector port and a DVI-I to VGA adapter.

William Frank] The ATTO UL4D is not the only ATTO SCSI card with G5 problems. I bought and subsequently returned an "unreturnable" Atto UL4S SCSI card, as being "Not fit for Purpose", because although the G5 still booted and it performed OK as a SCSI card with legacy external SCSI devices in my dual 1.8 GHz G5, it conflicted somehow with the OEM ATI 9600 card. All manner of video wierdnesses and lockups occurred and disappeared concident with whether or not the ATTO card was present.

Kevin Kirwan describes a bug with a Radeon 9600 video card in the Power Mac G5, fortunately resolved by an exceptionally good Apple Store "genius":

For months I have been experiencing the problem with my G5 waking from sleep with no video. I have a G5 Dual 2 Gb with a 20" Cinema display.

This problem had been getting worse, and I tried everything I found here on this site. I finally cracked and took it to the Genius Bar. After informing me I was 2 months out of warranty, he tried several things for 20-30 minutes including a Hardware test that turned up no problems. While restarting it to remove the disc and send me on the way, the "problem" occured!

Long story short, he worked on it further and found Apple has a documented hot issue (under CD issue) with the RV350/ATI Radeon 9600 Pro Video Card. He replaced it for free, and knock on wood I have once again been able to put m machine to sleep without worry.

Finally, a very high end AGP card for the G5 that does not suck up a PCI-X slot. Will look for it at MWSF. k
9800 SE Specifications

* 256MB DDR memory
* Dual Integrated 10-bit per channel 400MHz DACs
* Dual 165MHz TMDS transmitter (DVI compliant)
* Multiple display connections
* ADC port
* DVI-I port
* DVI-I to VGA adapter included

ATI Radeon 9600 256MB AGP 4X

GPU runs at 400MHz like the OEM Radeon 9600XT and 9650.
The memory clock is 270MHz (effectively 540MHz)
the OEM Radeon 9600XT came with 620MHz memory clock
the original Radeon 9600 Pro for the PC had a 600MHz memory clock.
All of the 96xx line feature a 128-bit wide memory bus offers 8.6GB/s of memory bandwidth.

ATI has 'quietly' changed the 9800 SE (G5 only).
The 9800 Pro no longer comes with 8X AGP rating. Though the replacement 9800 Pro is rated at 4X AGP, it will still work in the G5's 8X slot.

However, even though the older Radeon 9800 Pro 2X/4X yielded results slightly slower than the Radeon 9800 Pro Special Edition 8X (see the graphs above), that could be as much to with the memory difference (128MB vs 256MB) as the AGP rating. In the past, we have proven that an 8X card is no faster than a 4X card when all other specs are equal.

I doubt the AGP bus is being saturated beyond the capability of a 4X rating -- so ATI's decision to go with 4X doesn't really penalize the G5 user.

Update: didn't see the part where ATI will be killing off the current 9800's for 4x only model wtih 256MB (in addition to the new 9600 just announced) which will be for G4s and G5s, and for current price of $299 and require a power connector.

(ie, over-clock at your own risk)
If we were talking about an isolated situation with just one transistor, then there wouldn't be much of an argument, but with the X800 core, we're dealing with around 160 million transistors - greatly complicating things.

The problem with making smaller transistors running at high frequencies is that there ends up being a great degree of interference or crosstalk between adjacent wires connecting these transistors on the chip. The amount of crosstalk goes up as the operating frequency increases (and as the transistor size decreases), thus becoming a problem as you try and increase the clock of a GPU. ATIcceleratorII

ATI Radeon Mac Shop (http://shop.ati.com/searchresults.asp?dept_id=31) The new prices on 9800 (128MB and 256MB) are now available. $249 for the 2x/4x 128MB ME and $299 for 9800 SE (G5 only). $499 for the X800 XT.

"Quartz 2D Extreme" is the name for the new shader-based Quartz 2D acceleration in Tiger... Nothing to do with Quartz Extreme or Panther.

Massive 3D Rendering
With 16 parallel pixel pipelines, and six parallel vertex processing pipelines, the RADEON X800 XT Mac Edition delivers well over twice the horsepower of its highly acclaimed predecessor, the RADEON 9800 PRO.

By comparison, the RADEON X800 XT Mac Edition delivers these impressive performance gains:

* Pixel fill rate gain of 150%
* Memory bandwidth gain of 50%
* Geometry performance gain of 90%
* Floating point operations/sec. gain of 140%


ATI's second set of lower pricing numbers for the X800 and X800 XL was essentially incorrect. In reality, in the market, the 16-pipe Radeon X800 XL competes with the 16-pipe GeForce 6800 GT. The 12-pipe Radeon X800 competes with the 12-pipe GeForce 6800.

Operating Systems Support
* Mac¬ OS X 10.3.6 or higher

Display Support
* ADC port for Apple¬ digital displays
* Dual-Link DVI-I port for digital flat panel or CRT
* DVI to VGA adaptor included
* Drive two displays simultaneously with independent resolutions and refresh rates
* Built-in VERSAVISION» for portrait displays

gamers aren't the only ones who stand to benefit from the card. As more and more Macintosh creative applications leverage OpenGL -- especially with Mac OS X v10.4 "Tiger's" forthcoming release -- creative professionals will also see marked improvements in performance by switching to a faster card, according to Ossias."

ATI Radeon X800 XL - A $299 6800GT Competitor (http://www.anandtech.com/video/showdoc.aspx?i=2299)
Radeon X800 XT Mac Edition

ATI has officially announced via a press release the availability of the Radeon X800 XT Mac Edition. This card sports 256MB of GDDR 3 and will support 30" Apple Display thanks to its DDL plug. It has an additional ADC plug.

The Mac X800 XT has one Dual Link DVI and one ADC port and supports the Apple 30-inch Cinema HD Display as well as legacy Apple ADC Displays and (with adapters), VGA monitors. The X800 XT features 16 pixel pipelines, six vertex pipelines and 256MB of GDDR3 memory.

Another advantage of this card, it should not sacrifice a PCI-X slot when installed in its AGP slot. The official price is $499, same price than the nVIDIA 6800 GT and $100 less than the nVIDIA 6800 Ultra.

This card only exist as PCI Express format, so ATI must have used a bridge to retro-adapt it to AGP slot.

The Dell display also offers a wealth of connectivity options, including VGA, DVI, composite, component, and S-video connections. It also has integrated picture-in-picture (PiP) that works with any pair of inputs. The PiP lets you display a small window in one corner (user-selectable) or side-by-side windows. The addition of component inputs is welcome and makes the unit suitable as a small HDTV monitor. But the DVI input does not support HDCP content protection, so you can't use it with HDTV sources that require HDCP. Since this is primarily a desktop PC monitor, it also lacks HDMI connections.

Apple's 23-inch Cinema HD can be found for under $1,600 if you look hard enough.

Dell UltraSharp 2405FPW Widescreen LCD (http://www.extremetech.com/article2/0,1558,1764465,00.asp)
The UltraSharp(TM) 2405FPW will be on sale for $1,199 in the Americas and Europe on March 1, 2005. The wide-screen monitor is ideal for graphics professionals, computing enthusiasts and gamers. The native resolution of 1920x1200(b) helps ensure detailed images are crisp and clear and typical response times of 12ms(c) mean fast-moving content is displayed with minimal distortion.

About doing a clean install of OS X with Retail Radeon:

ATI Display Drivers and Support Files Information for Mac OS X

For all ATI retail Mac graphics products, the software is made up of:

* ATI Display Drivers
* ATI Support Files (such as the ATI ROM Xtender, and ATI Displays)

The drivers from your ATI Installation CD or Retail Updates on ati.com are always Mac OS version specific, while the included support files will generally support a broad range of OS versions.

With the Mac OS X updates available from Apple's website only the core display driver is updated; all the preinstalled ATI support files (such as the ATI ROM Xtender and ATI Displays) from your installation CD or later updates from ati.com should remain intact, and continue to operate. If you are performing a Mac OS X update, you should not remove the ATI support files prior to or after updating your OS.

If you are performing a clean install of the OS, it is important to update the OS to the minimum requirements as mentioned on the retail box or the specifications page on ati.com before running your original installation CD or Retail Updates.

Similarly, if you run a clean install of an OS that is newer than what is mentioned on the retail box or product specifications page, we recommend running your original installation CD at minimum, or the latest web release of the ATI Retail Update to ensure that the required ATI support files are installed. Running without the ATI support files may cause anywhere from a loss in some features, to complete loss of acceleration and display mode options (depending on your retail hardware).

Radeon 9200 and ATIcellerator II

Just installed Radeon 9200 in Beige G3 (PL 1.0GHz) I then tried using ATIccelerator II 1.05a and it reports memory at 100MHz -50% (instead of 200MHz). The last ROM ATIccelerator shows support for 9200 is 124. Any attempt to adjust memory results in artifacts, and eventual freeze-up or no screen visible.

ATI Radeon 9200:?Chipset Model: ATY,RV280?Type: Display?Bus: PCI?Slot: C1?VRAM (Total): 128 MB?Vendor: ATI (0x1002)?Device ID: 0x5961?Revision ID: 0x0001?ROM Revision: 113-A27502-127
FCode Version: 1.94?NDRV Version: 1.0.1f59

Not bad and similar in performance to Radeon 9000. Not a big change from earlier Radeon PCI cards, but some, and should have better support under OS X Tiger and moving forward.

Is that because it is a 32-bit/33MHz slot? I am vaguely recalling that the first 64-bit/33MHz PCI slot was the B&W. k

GPU runs at 400MHz like the OEM Radeon 9600XT and 9650.
The memory clock is 270MHz (effectively 540MHz)
the OEM Radeon 9600XT came with 620MHz memory clock
the original Radeon 9600 Pro for the PC had a 600MHz memory clock.
All of the 96xx line feature a 128-bit wide memory bus offers 8.6GB/s of memory bandwidth.

AGP 4X card that'll work in both 4X and 8X slots, meaning that it can be used in both Power Mac G4 and G5 systems, as well as PCs.

The card features two DVI outputs, one of which is driven by the two external Silicon Image TMDS transmitters on the board itself. The two TMDS transmitters in conjunction enable one of the DVI outputs to support dual-link displays, such as the 30" Cinema Display, at full resolution.

The dual-link DVI port supports a maximum 330MHz pixel clock, and only approximately 270MHz is required to drive the 30" Cinema Display's 2560 x 1600 resolution.

At the 2560 x 1600 native resolution of the 30" Cinema Display, 256MB of local frame buffer is necessary to avoid swapping to system memory when you have a lot going on in OS X.

In fact, the general UI performance of the 256MB Radeon 9600 Pro Mac & PC Edition is identical to that of a Radeon X800 XT Mac Edition, even when running on a 30" Cinema Display at native resolution.

With the RV350 GPU at its heart, the Radeon 9600 Pro Mac & PC Edition is for those users who want a video card for everything but games. Or Motion that actually depend on good pixel shader performance.

The 9600 Pro Mac & PC Edition is entirely passively cooled, and thus, is silent.

The Radeon X800 XT will receive a price cut sometime this month from $499 to $399. The Radeon 9800 Pro Mac Special Edition will be killed off, as will the 128MB 9800 Pro, and both will be replaced by a single AGP 4X Radeon 9800 Pro with 256MB of memory priced at $299.

System Requirements -
Power Mac G4, G5 from Apple or PC
AGP* graphics slot available on the motherboard
300-Watt power supply or greater recommended

Some benchmarks comparing the 9800.

ANALYSIS: How can a 2X/4X AGP card run as fast as an 8X AGP card? Because even at 4X, the AGP bus isn't saturated. In reality, the 8X bus is under-utilized.

Flashing Radeon 9800 XT to use in Mac:
XT Extreme (http://www.amacapart.com/images/xtres.jpg)
9800XT 256MB - 8 chips - "They call it an XT..."

Core speed: 412MHz
RAM speed: 365MHz DDR

All other details correspond with 9800 Pro

Notes: Basically a 9800 Pro with a bad additude ;) Same flashing-related details apply to above card.

9800 Pro 256MB - 16 chips

Core speed: 380MHz
RAM speed: 340MHz DDR
Note: Cards (such as the one pictured) with only one gap ("key") in the gold AGP connector are 4x/8x Compatible only, and will work only in G4 Towers Digital Audio (466+MHz) and newer, as well as G5's.

All other details same as above

Notes: One way to get double the RAM is to double the chips - and that's just what ATI did with this card. I believe these are actually XT's at somewhat lower clock speeds. At this time, one can flash with the 9800XT ROM and use all 256MB, but get VGA video only. The alternative is to flash with the 9800 Pro ROM, which will allow only 128MB to be used, but all ports will function. Prices are coming down on these cards, and they may not be a bad buy - you can flash with the 128MB ROM now and wait for a possible future ROM to unlock all the VRAM

9800XT 256MB

Core speed: 412MHz
RAM speed: 365MHz DDR
Pipelines: 8 (full)
Memory bus: 256-bit (full)
AGP: 4x + 8x Compatible - Digital Audio & newer Tower G4's and Tower G5's with AGP slots

Note: Cards (such as the one pictured) with only one gap ("key") in the gold AGP connector are 4x/8x Compatible only, and will work only in G4 Towers Digital Audio (466+MHz) and newer, as well as G5's.

Ports: DVI-I, VGA, and S-Video All fully functional with Pro ROM, VGA only with XT ROM
G4 Cube: Not compatible.
ROM chip: 64 or 128k
Reduced ROM: Pro ROM only
Notes: You like 'em fast? Then this is your card.

When flashed with the Mac XT ROM: This card can use all 256MB of RAM, and, in most cases, variable speed fan control works as well. However, the DVI port will only output analog video, meaning that it cannot drive a DVI display; only a VGA monitor through an adapter. The S-Video port will not function.

When flashed with the 9800 Pro ROM: The card can only use 128MB of RAM, but all ports will function correctly. The card's fan will run at full speed all the time.

There exists a modified 256MB Pro ROM made by Arti at Strangedogs that may allow this card to use all ports correctly as well as all 256MB of RAM - the only thing lacking, in theory, would be variable fan speeds. This configuration has not been tested, but if you have an XT card, I encourage you to try it out, and report your findings to the forums.

Radeon X1900 G5 Edition Feedback
(fan, cooler swap, performance...) -

" Hi there, just a few notes on the ATI X1900 G5 Edition (http://eshop.macsales.com/Item_XLR8YourMac.cfm?ID=9156&Item=ATI100435854) install in my Dualcore 2.3GHz you might be interested in.

1) As installed, thought it was kinda noisy under load (one of my games will drive the card to 100% usage before actual gameplay so you can let it sit and listen to it spool).

3) Installed the Accelero X2 cooler on it to combat noise. (see previous article here on Low Cost Mac ATI X1900 XT Quiet Cooler (Accelero X2) (http://www.xlr8yourmac.com/Graphics/Mac_X1900XT_Silent_Cooler.html#storytop))

I don't have any official results ... but Quake 4, UT 2004, Doom 3 and Warbirds 2006 are all smokin fast no, no glitches or issues. Warbirds 2006 with everything at highest setting and 1600x1000 plus second 17" monitor averages 150 fps. UT 2004 goes over 200 all the time.

I have not run the benchmarks yet as I can't seem to get the new Santaduck setup working properly (sent an e-mail about that)...not sure why. Games are a joy!

6) Here is the big one. fan noise... it turns out

the Apple fan used for the "slots bay" gets it speed signal from the current draw in the slots.

(This came up a couple years ago in an article on 6800 card user feedback IIRC (and again with the X800 AGP card) where some users thought the card fan was the noise culprit, but sometimes it's the bay fan instead). The author of hardware monitor mentioned back then that the PCI bays fan speed/duty cycle is determined by current draw, not temperature.-Mike)

That fan was hitting 3000 rpm at high load. I removed the 6600 that I had transferred to slot 3 (8x), which obviously dropped the power draw, and that fan now only hits 2500rpm. Its better for sure, but still kinda noisy. I wanted to replace it with a Panaflo or similar, but the problem is Apple uses a 4 wire fan with a special connector...and all the wires are black so not sure how to wire up a new one. (if you had a meter you could check the pinout-Mike) Apple fan is Delta EFB0812HHE, 80x80x38mm. This fan is the noise culprit now.

7) So to be fair I would have to put stock fan back on, and try it again with only the X1900 card in place, as the fan noise I heard was certainly influenced by the extra current draw running the slots fan up to max rpm.

forces the card GPU onto the cooler surface. I re-installed that piece using original screws. Seemed like a good idea as it ensures positive contact with cooler. Used the stock X2 thermal compound.

New bridge chip to bring GeForce 8 series to AGP

Due to continued demand, particularly from Internet cafe and emerging markets, for AGP-based products, Nvidia is scheduled to launch an updated bridge chip which supports the company's newer GPUs in October, according to sources at graphics card makers.

Nvidia's BR02 chip was designed to convert the company's PCI Express-based GeForce 7600 (G73) GPU to support AGP, however, this chip is not compatible with GeForce 8 series GPUs. A new version, A05, will work with current GeForce 8600 (G86) and 8400 (G84) GPUs and well as the upcoming G92 and G98, noted the sources.

In related news, AMD also planned to introduce AGP versions of its Radeon HD 2600 (R630) and 2400 (R610) GPUs, but has encountered driver instability issues related to DirectX 10 and HDMI support, according to sources. These problems should be resolved by the end of this month, they added.

AMD and Nvidia declined the opportunity to respond to this report saying they cannot comment on unannounced products.

AMD preps 55nm versions of Radeon HD 2600, 2400
September 10, 2007

New versions of AMD's Radeon HD 2600- and Radeon HD 2400-series graphics cards will roll out in January 2008,

Their current 65nm RV630 and RV610 graphics processors, the updated cards will be outfitted with new RV635 and RV620 GPUs based on 55nm process technology.

The smaller process should reduce power consumption and allow for higher clock speeds, core frequencies will only be increased to 800MHz (the Radeon HD 2600 XT already runs at 800MHz by default, while the Radeon HD 2400 XT is clocked at 700MHz).

DirectX 10.1 API support as well as PCI Express 2.0 connectivity and DisplayPort display outputs.
