Model
ATI's main brand Radeon (RA) series, with its models from the early Radeon Xpress 200 to Radeon (X300, X550, X600, X700, X800, X850) to the recent Radeon (X1300, X1600, X1800 , X1900, X1950) performance in descending order from low to high.
The main brand of Nvidia is the GeForce series, which is made up of early GeForce 256, GeForce2 (100/200/400), GeForce3 (200/500), GeForce4
(420/440/460/4000/4200/4400/4600/4800) to GeForce FX (5200/5500/5600/5700/5800/5900/5950), GeForce (6100/6150/6200/ 6400/6500/6600/6800/) to near its GeForce (7300/7600/7800/7900/7950) performance in descending order from low to high.
Version level
In addition to the above standard version, there are special editions, special editions will generally be added to the standard version of the following suffix, common are:
Ati:
SE (simplify Edition simplified version) usually has only 64bit memory interface, or the number of pixel pipelining is reduced.
Pro (Professional Edition Pro) high-frequency version, generally compared to the standard version in the number of lines/vertices and frequency of these aspects are a little higher.
The XT (EXTreme high-end version) is the high-end of the ATI series, and Nvidia is used as a low-end model.
XT PE (EXTreme premium Edition XT Platinum Edition) high-end model.
XL (lower end models in EXtreme Limited high-end series) ATI's latest R430 in the high-frequency version
XTX (XT eXtreme High-end version) the new naming convention after the release of the X1000 series.
CE (Crossfire Edition Cross-fire version) Cross fire.
VIVO (video in and video out) means that the graphics card has two main functions, which are audio input and visual capture.
HM (Hyper memory) video card that can occupy
Nvidia:
ZT on the basis of the XT again down frequency to reduce the price.
XT, which is the highest end in ATI.
LE (Lower Edition low-end version) and XT basically the same, ATI also used.
MX Parity edition, Volkswagen class.
GTS/GS low-frequency version.
GE slightly stronger than GS, in fact, is super-frequency GS.
GT High frequency version. A grade higher than the GS because the GT did not shrink the pipeline and vertex units.
GTO is slightly stronger than GT, a bit of a GTO in the car.
The Ultra represents the highest end before the GF7 series, but the top end of the 7 series is renamed GTX.
The GTX (GT eXtreme) enhanced version, which reduces the frequency or shrinks the flow pipeline, becomes the GT and continues to shrink to become the GS version.
GT2 dual GPU graphics.
Ti (Titanium Titanium) is generally representative of the high-end version of Nvidia.
Go Multi-language mobile platform.
TC (Turbo Cache) can occupy memory of the video card
