In addition, the recommended performance goal for the video adapter (VGA+) is 1.2 million pixels per second using 40 percent or less of the CPU bandwidth. The device-independent bitmaps (DIBs) used to measure this performance goal have color depths of 1, 4, and 8 bits, and can use run-length encoding or be unencoded. A second method of measuring the video performance is to deliver 256-color, 320 by 240 pixel digital-video images at 15 frames per second.
