High Impact was the midrange IMPACT graphics option on the SGI Indigo2. It is a SGI Solid IMPACT with texture RAM (TRAM), roughly equivalent to a SI+T option in the Octane. It should not be confused with the SSI/SSE graphics option in the Octane, which is a SGI Maximum IMPACT system without TRAM, meaning it has twice the 3D processing capability (except for hardware-accelerated texture mapping, which the SSI/SSE lack altogether due to not having TRAM) and twice the framebuffer of a High Impact system.
