The CPU types, the amount of RAM, and graphics capabilities, depend on the model or sub-model variation.

Power Indigo2 is a version of the teal Indigo2, with the R8000 chipset and strong floating-point arithmetic performance.

Each microprocessor family differs in clock frequency, and in primary and secondary cache capacity.

The design of the memory control logic in R10000 machines support up to 1 GB RAM, but the thermal output of older generation of DRAM chips necessitate the 512 MB limit.

With newer, higher-density and smaller scale modules, 768 MB is easily within heat output specifications.

These options are based on the same Express Graphics architecture from the original SGI Indigo, but feature improved performance.

Of all contemporaries, Maximum IMPACT graphics is the world's fastest desktop visualization solution.

A Maximum IMPACT with 4 MB of texture memory and the correct graphics settings can play the first three of the Quake video game series with acceptable frame rates.

The Indigo2's successor, the SGI Octane, has an upgraded XIO bus and the same graphics options in repackaged form.
