3.2.2  ATI Radeon Graphics Cards                                 CTPCI

ATI Radeon is a brand of graphics processing units (GPU) that have 
been manufactured by ATI Technologies since 2000, and is the 
successor to their Rage line. AMD took over ATI Technologies in 2006, 
but the brand name has been retained.

Retail card manufacturers take the ATI chip designs and create cards 
which actually get put on store shelves. Some years ago, ATI/AMD sold 
Radeon cards at the retail level, too. Each different retail version 
of a card has different properties. It may have a redesigned cooler, 
or different inputs and outputs, or even higher clock speeds. Each 
card is different because each board partner is trying to stand out 
in the crowd. However, in general, all these retail cards are 
essentially identical. Board manufacturers of the Radeon include 
Diamond Multimedia, Sapphire Technology, AsusTek, HIS - Hightech 
Information System Limited, Micro-Star International, PowerColor, 
Gigabyte and VisionTek.

                should have called it Radeon 9250 SE)

There are many ATI Radeon product generations and models. This is the 
desktop series (there is also a mobility and workstation series):
 - ATI Radeon 7000 series, initially only Radeon
 - ATI Radeon 8000 series
 - ATI Radeon 9000 series
 - ATI Radeon X series
 - ATI Radeon X1000 series
 - ATI Radeon HD 2000 series
 - ATI Radeon HD 3000 series
 - ATI Radeon HD 4000 series
 - ATI Radeon HD 5000 series 

The ATI Radeon chipsets are named as follows: Rxxx or RVxxx (for 
example, R100 or RV100). The RVxxx are low-cost variants (V = value); 
their performance is sometimes considerably reduced. The numbering is 
not always chronological, and processors with a higher number do not 
have necessarily a better performance.

The fVDI driver supports PCI video boards based on the ATI chips 
Radeon R100 (7xxx), R200 (8xxx, 9xxx) and R300 (9xxx) series. The 
following table lists the graphics cards with PCI interface that can 
be used. You will notice that some GPUs are missing. This is because 
some Radeon series were produced just for the Accelerated Graphics 
Port (AGP, a high-speed channel for attaching a video card to the 
computer's motherboard).

 (1) The core/memory clock is the reference core/memory clock 
     frequency, used as some manufacturers adjust clocks lower and 
     higher. This number is that listed by ATI/AMD.
     DDR (double data rate) memory can read from/write to memory 
     twice every clock cycle. So if your DDR memory clock is 250 MHz, 
     the effective clock speed is 500 MHz.
 (2) The fillrate is the maximum theoretical fillrate in textured 
     pixels per second. This number is generally used as a 'maximum 
     throughput number' for the GPU and generally, a higher fillrate 
     corresponds to a more powerful (and faster) GPU.
 (3) Later known as Radeon 7200.
 (4) The All-in-Wonder (AIW) video boards were a combination graphics/
     TV tuner card.
 (5) The Radeon All-in-Wonder VE was based on the Radeon 7500.
 (6) The Radeon 9100 was a slightly modified Radeon 8500 with the 
     same GPU.

There are models with some nice features like DVI output, dual 
monitor display output, TV tuner with audio and S/PDIF outputs, audio/
video inputs. According to Didier Méquignon, the author of the 
driver, all the listed boards should work but only their common 
standard features. Do not expect to use your TV tuner in a GEM 
window. Some features may be later supported by the driver.
