What is the core bit width in the video card?

The display chip bit width refers to the display chip internal data bus's bit width, that is, the display chip in the internal use of data transfer digits, the current mainstream display chips are basically using the 256-bit width, the use of greater bit width means that in the data transmission speed unchanged, the instantaneous transmission of the amount of data is larger. Is like a different caliber valve, in the case of a certain flow speed, the caliber of large can provide a larger amount of effluent. The display chip bit width is displays the chip internal bus the bandwidth, the bandwidth is bigger, may provide the computation ability and the data throughput ability is also quicker, is decides the chip level important data one. At present, the largest display chip bit width is 512 bits, which is a Parhelia-512 video card from Matrox (Magic Day), which is the world's first display chip with 512-bit width. At present, all the mainstream display chips in the market, including Nvidia's GeForce series graphics card, AMD's Radeon series, all adopt 256 bit width. The two largest display chip manufacturing companies in the world are also expected to adopt 512-bit widths in the next few years.

The increase in the display chip bit width does not mean that the chip is more powerful, because the display chip integration is quite high, the design, the manufacture all needs the very high technical ability, the simple emphasis displays the chip bit width does not have the big significance, only in other parts, the chip design, the manufacture craft and so on aspect all fully fits the case, Show the role of chip bit width can be reflected.
