15 bits per pixel, 32768 colors, Real Color.The usual pixel formats specify how many bits per pixel are allocated to the color channels. The color depth of the frame buffer determines the maximum number of colors displayed on the screen. Exactly one area of the frame buffer is allocated to each screen pixel. The frame buffer is the part of the video RAM that corresponds to the digital copy of a monitor image. Pixels and related information such as position, location or color depth of a displayed object are stored in the respective areas. These include:Įach individual area fulfills different functions. The working memory of the graphics card is divided into individual memory ranges. The MSI AMD Radeon R9 390 can point to 8 GB of DDR5 memory, where the 5 is the designation for the fifth version. DDR is an abbreviation for “Double Date Rate” and characterizes a certain type of RAM, whereby the transfer rate is doubled during data transfer. Many graphics memories today have the size of a RAM of several GB with the corresponding performance.įor control purposes, a memory controller is installed on the graphics card, which controls access to the memory. The capacity of the memory determines the image resolution and the maximum color depth of the monitor. The memory stores the data and serves as storage for the GPU. The graphics cards have their own working memory and additional memory connection with high clock rates. Does a new graphics card also require a power supply with more power?.Are the PCIe graphics cards faster than the AGP devices?.How does a PCIe graphics card differ from an AGP model?.
