The CL-GD546X is the Laguna® family of Rambus®-based 2D/3D graphics accelerators. The CL-GD5464 and CL-GD5465 offer 3D-graphics capability in addition to maintaining the same high level of 2D performance offered by the CL-GD5462.

The CL-GD5464 operates as a PCI bus master for maximum system throughput. The CL-GD5465 also supports Intel® AGP (accelerated graphics port) for higher bandwidth between the system memory and the graphics subsystem.

The CL-GD5464 offers very cost-effective hardware acceleration for the latest generation of 3D games that rely heavily on texture mapping to achieve a dramatic experience for the end user. The rendering performance is tuned to Microsoft® Direct3D(TM) game API. The CL-GD5464 is also compatible with other 3D game APIs on the market.
