: Video card memory and bit width as well as the core frequency and memory frequency and so on, also note that the heat dissipation. At present, the general display Cashiancun are 512M, the bit width is 128bit, the larger the number of graphics card performance better. The graphics

even the price of each other to the high cost of the imac computer involved. In fact, the small part of the graphics, for any video card, 3D performance is important, but the final display of quality is equally important. If you think of 3D performance as a manifestation of intrinsic performance, so the final display on the screen is good for the player will be

Widescreen displays are popular as a result of cutting more provincial materials, and the widescreen desktop gives us a better sense of Windows usage.

Every time there is a new graphics card release, a rice, n rice heated debate is very detailed content, in addition to video card game performance, power, temperature and other key indicators, memory bit width is one of the controversial points, high-end graphics card with 3

In fact, the graphics card temperature is generally the highest temperature in the entire chassis, standby or conventional 50-70 ℃ (or lower), run a large 3D game or play high-definition video, the temperature can be as high as 90 ℃ or so, the general high load under no more than 100 ℃ are considered normal category. If necessary, the fan speed can be adjusted to the appropriate height. In other words, the
