This page contains information about Radeon chipset naming, and some other, possibly outdated information.
The main portal for 3D acceleration on Radeon is aptly named Radeon.
Note this tables mainly applies to x86 machines. We make a best effort to support PowerPC/Sun cards with, but we cannot always support these due to Apple/Sun hardcoding most of the details in their drivers.
Radeon VE (1 texture pipeline, no TCL) Rereleased Radeons:
Radeon 7000 / M6 (1 texture pipeline, no TCL) The only differences between the releases are more RAM and higher clock speeds (possible due to a manufacturing process shrink) on the 7000.
- Radeon SDR
Radeon DDR / LE Rereleased Radeons:
Radeon 7200 (SDR / DDR) The only differences between the releases are more RAM and higher clock speeds (possible due to a manufacturing process shrink) on the 7X00 cards.
- Radeon 7500 (DDR)
- FireGL 7800 (Mobile) The 7500 has a tweaked core, more RAM and higher clock speeds (possible due to a manufacturing process shrink). Despite the name (rv200), these cards are r100 based.
- Radeon 8500 LE
- Radeon 8500
- Radeon 9100
- FireGL 8700
- FireGL 8800 The difference between the 8500, 8500 LE, 8700, and the 8800 is clock speed. The 8500 LE is made by third party manufacturers.
The amounts of memory on these cards differs eg the 8800 has twice the memory as the 8700.
All are based on the R200 chipset (this is why they can all use the FireGL drivers) and have DDR.
The Radeon 9100 is a rerelease of the Radeon 8500 because it is faster than the Radeon 9000 (see below), the windows drivers offer "pixel shader supported video deblocking filtering" for this card.
- Radeon 9000
- Radeon 9000 Pro The 9000 cards use the Rv250 chipset which is a heavily modified R200 chip, the clock speed increased, the number of texture units per pipeline halved, while the windows drivers offer "pixel shader supported video deblocking filtering" for this card.
- Radeon 9200SE
- Radeon 9200
- Radeon 9250 The difference between the Rv250 and the Rv280 is that the R9200 has AGP 8x while the Rv250 has AGP 4x.
The 9200SE is a toned down version of the 9200 and has half the memory bandwidth (64 bit versus 128 bit) and lower clock speed (200 MHz versus 250 MHz).
One problem with the 9200SE is that some older XFree86 servers will not detect the chipset. To make this work, you can manually set the
ChipID 0x5964 or
ChipID 0x5961 to the Device line.

Status (see also the r300 portal) Unstable.
Started as r300 project, currently maintained in Mesa 3D, 3D driver for r3xx-r5xx cards. To build the latest version see Building.
- Radeon 9500
- Radeon 9500 Pro
- Radeon 9700
- Radeon 9700 Pro The main difference between the 9500 Pro, and the 9500 is the number or rendering pipelines, half have been disabled in the 9500.
The main difference between the 9500 cards, and the 9700 cards is the bus width, 128 bit for 9500's, 256 bit for 9700's.
The difference between the 9700 Pro, and the 9700 is clock speed. The 9700 is made by third party manufacturers.
All are based on the R300 chipset (this is probably why they can all use the FireGL drivers) and have DDR.
- Radeon 9600
- Radeon 9600 Pro The 9600 uses the Rv350 chipset which is a heavily modified R300 chip, the clock speed increased, the memory interface and Hyper-Z optimized, the number of pipelines halved, using a 0.13Âµm process.
- Radeon 9800
- Radeon 9800 Pro Both these cards use the R350 chip which is a R300 chip which has been modified to be more efficient by improving its Hyper-Z implementation and colour compression algorithms, they also have a higher clock.
The difference between the 9800 Pro and the 9800 is clock speed.
- Radeon 9600 XT The only differences between the rv350 and the rv360 appear to be an improvement in the manufacturing process and a boost in speed.
- Radeon 9800 XT

- Radeon X300

All radeons have open source 2D support. Note that R600/R700 series chips (X2300, X4650 etc.) are only recently supported by the "radeon" driver.
As of September 2007, 6.7.194 driver may give better results with EXA output, instead of XAA. This will change DRI rendering performance also.
The new radeonhd driver was initially to offer the sole support for R500/R600/R700 cards, but nowadays also the radeon driver supports those. It's therefore overlapping with radeon's card support, and radeonhd might be merged to radeon at some point if there's no use for a separate "newer" driver.
The vesa driver can be used on most cards (no acceleration).
You also get fancy versions of most of these cards, e.g. VIVO, AIW, etc. This is just added functionality, i.e. stick on a TV tuner, a couple of chips.
The reason for the renaming is to simplify matters for end users i.e. bigger number = better / faster. However rv#00 chipsets are cut down and thus slower versions of the R#00 chipsets with the same model number (and are often even slower than lower-numbered chipsets). The exception is the rv200 which is actually a faster version of the r100 core.

The Radeon IGP chipsets do not have discrete video ram. They share system ram much like the Intel i8xx chips, and VIA/S3 ProSavage/Twister chips. There is support for 2D and 3D acceleration for the IGP chipsets in DRI and Mesa CVS. There is experimental 3D for Xpress 200M Northbridge integrated GPUs (june 2007).
All Radeon's except the 7200 (r100) have two crtcs and a built-in LVDS/TMDS controller. Not all OEMs connect these to actual ports so you may see boards that only support 1 head.
Until driver version 6.7, if you wanted to use HW accelerated 3D on both heads of a dualheaded radeon card, you had to use the Radeon MergedFB option by AlexDeucher. Since version 6.7, the driver supports Randr 1.2, which allows screen hot (un)plugging, and dynamic multiheads. Just try "xrandr --auto" to get to biggest possible mode. A big "Virtual" option is needed to allow big multiheads.

Further finer, and per application, user-space configuration is achieved with DriConf
Alternatively proprietary non-libre 2D and 3D support is available through ATI/AMD's Fire GL linux driver "fglrx"
