Chapter 7 Configuring Key ForceWare Graphics Driver Features Examples of GeForce-based Graphics Cards Supporting SLI NVIDIA SLI operation requires two SLI technology-capable graphics cards that have similar core GPUs. Examples of SLI technology-capable GeForce-based graphics cards are listed below. Note: An SLI bridge connector (provided with your graphics card) must also be installed to utilize the full capabilities of SLI frame rendering. • GeForce 7800 GTX series is the NVIDIA top-of-the line high-performance GPUs unmatched in speed and image quality. • GeForce 7800 GT is another model of the GeForce 7800 series of GPUs that supports SLI technology. • GeForce 6800 Ultra - the flagship chip in the 6000 series with 16 pixel pipes and 6 vertex units delivers exceptional performance and was the first GPU to deliver support for Microsoft DirectX 9.0 Shader Model 3.0. • GeForce 6800 GT has the same 16 pixel pipe and 6 vertex unit design, same GDDR3 support, and same Shader Model 3.0 support as the 6800 Ultra, but at slightly lower performance and a lower price point. In addition, the GeForce 6800 GT also offers a single slot thermal solution with lower power requirements. • GeForce 6800 includes 16 pixel pipes and 5 vertex units (instead of 6 vertex units in higher speed 6800 versions), and lower clock speeds to target the price-sensitive performance market. • GeForce 6800 LE satisfies the entry-level performance market still with a 256-bit memory interface, but with 8 pixel pipelines and 4 vertex units. • GeForce 6800 XT and GeForce 6800 XE are other models of the GeForce 6800 series of GPUs supported by SLI technology. • GeForce 6600 GT delivers enthusiast-class features and performance to the midrange price point and is the only GPU in the mainstream segment that is compatible with SLI technology. Additional features include: • GDDR3 memory clocked at 500 MHz • Fast 500MHz core clock • 128-bit memory interface, 8 pixel pipes, and 3 vertex units. • Supports Microsoft DirectX 9.0 Shader Model 3.0. • GeForce 6600 and GeForce 6600 LE are other models of the GeForce 6600 series of GPUs that are supported by SLI technology.
