The Intel® 845GV Graphics Memory Controller Hub (the 845GV
GMCH) is Intel’s first memory controller hub with integrated graphics
for the Intel Pentium® 4 processor. The 845GV GMCH, with its new
architecture graphics engine, delivers not only high 2D/3D graphics per-
formance, but also provides efficient, high bandwidth communication
channels connecting the processor, the memory, the I/O subsystem, and
other components together to deliver a stable mainstream desktop plat-
form solution. The features include:
• Built-in 2D/3D VGA controller.
