显卡小知识（Graphics knowledge） The main components of video cards 1, display chip (model, version level, development code, manufacturing process, core frequency) 2, memory (type, width, capacity, speed, frequency, package type) 3. Technology (pixel shader, pipeline, vertex shader engine, 3D, API, RAMDAC frequency, and support MAX resolution) 4 、 PCB board (PCB layer, video card interface, output interface, heat sink) 5, brand 1 、 display chip Display chip, also known as graphics processor - GPU, its role in the graphics card, just as the role of CPU in the computer. A more direct metaphor is the role of the brain in the human body. First, a brief overview of the common production display chip manufacturers: Intel, ATI, nVidia, VIA (S3), SIS, Matrox, 3D, Labs. Intel, VIA (S3) and SIS mainly produce integrated chips; ATI and nVidia based on independent chip, is the mainstream of the current market, but because ATi has now been AMD acquisition, and later on whether it will continue to stand-alone display chip is hard to say; Matrox and 3D Labs are geared primarily to the professional graphics market. As ATI and nVidia occupy the mainstream graphics market basically, the following will mainly introduce the products of these two companies. Model The companys main brand ATi Radeon (RA) series, the type of the Radeon Xpress from early 200 to Radeon (X300, X550, X600, X700, X800, X850) to the near Radeon (X1300, X1600, X1800, X1900, X1950) are from low to high performance. The main brand GeForce series of nVIDIA company, the model by the GeForce as early as 256, GeForce2 (100/200/400), GeForce3 (200/500), GeForce4 (420/440/460/4000/4200/4400/4600/4800) to GeForceFX (5200/5500/5600/5700/5800/5900/5950), GeForce (6100/ 6150/6200/6400/6500/6600/6800/) to GeForce (7300/7600/7800/7900/7950) in its performance in order from low to high. XT down version, and in the ATi that the most high-end. LE (Lower Edition low-end version) and XT basically the same, ATi also used. MX parity edition
