- Interface: PCI-Express x16
- GPU (ROPs/Shaders) clock rate: 600/1512 MHz (nominal)
- Memory clock rate, physical (effective): 1000 (2000) MHz (nominal)
- Bus width: 2 x 256-bit
- Vertex processors: -
- Pixel processors: -
- Unified processors: 2 x 128

- Multi-GPU: Hardware SLI for own GPUs + Hardware SLI for the second card
This card requires a DVI-to-D-Sub adapter to be connected to an analog monitor with a D-Sub interface.
Maximum resolutions and frequencies:
- 240 Hz maximum refresh rate
- 2048 x 1536 x 32bit @ 85Hz Max - analog interface
- 2560 x 1600 @ 60Hz Max - digital interface (all Dual-Link DVIs)
MPEG2 playback (DVD-Video) was analyzed back in 2002 and little has changed since that time. Modern graphics cards do not load CPUs during video playback by more than 25%.
