The MX86251 is based on proven MX86250 2D/Video window accelerator technology, while adding many enhancements to the base functionality. All processing engines on the chip are running on a faster clock, up to 75 MHz which means 600 MB/sec peak memory bandwidth. Higher bandwidth means higher 2D performance and higher frame rate Video. The Linear Frame Buffer write cycle from the PCI bus is now executed in one clock cycle. That is, the CPU now has much greater write bandwidth into frame buffer memory. The on chip RAMDAC is enhanced to 160 MHz to enable many high resolution video modes. Contrast and Brightness adjustments are added to the Video Processor so that dark MPEG-1 videos will look much better on the screen. ALL these features of the MX86251 combines to make a powerful graphics experience for multimedia.
