Original Radeons:
Rereleased Radeons:
The only differences between the releases are more RAM and higher clock speeds (possible due to a manufacturing process shrink) on the 7000.
Original Radeons:
Rereleased Radeons:
The only differences between the releases are more RAM and higher clock speeds (possible due to a manufacturing process shrink) on the 7X00 cards.
The 7500 has a tweaked core, more RAM and higher clock speeds (possible due to a manufacturing process shrink).
Radeon 2:
The difference between the 8500, 8500 LE, 8700, and the 8800 is clockspeed. 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 2:
The 9000 cards use the Rv250 chipset which is a heavily modified R200 chip, the clockspeed increased, the number of texture units per pipeline halved, while the windows drivers offer "pixel shader supported video deblocking filtering" for this card.
Radeon 2:
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 0x5963
to the Device line.

Radeon 3:
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 clockspeed. 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 3:
The 9600 uses the Rv350 chipset which is a heavily modified R300 chip, the clockspeed increased, the memory interface and Hyper-Z optimized, the number of pipelines halved, using a 0.13µm process.
Radeon 3:
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 clockspeed.
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.
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 versions of R#00 chipsets, and are thus slower than R#00 chipsets even if they have higher model numbers.
Furthermore:
Legend:
All Radeon's except the 7200 (r100) have two ramdacs, 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.
If you want to use HW accelerated 3D on both heads of a dualheaded radeon card, you will need to use the Radeon MergedFB option by AlexDeucher. MergedFB is now available in DRI CVS.
All radeons have open source 2D support.
Open source 3D acceleration is available on all radeons up to and including the 9200 (rv280). 3D support for r300 based cards (9500 and above) is only available from ati's binary driver.
