IMPACT graphics gives the workstation real-time 2D and 3D graphics rendering capability similar to that of even high-end PCs made well after IMPACT's introduction.
IMPACT Graphics can produce resolutions up to 1600 x 1200 pixels with 32-bit color[2] and can also process unencoded NTSC and PAL analog television signals.
The equivalent configurations also exist for the SGI Octane workstation but are referred to as SI, SSI, and MXI (I-series).
Later Octane workstations used a similar configuration but with updated ASIC chips and are referred to as SE, SSE, and MXE (E-series).
IMPACT uses Rambus RDRAM for texture memory.
