The idea behind the RISC processor was that because it's hard to optimize hardware you'd get a faster machine if you concentrated your efforts on the few instructions you use often and then made the complex instructions out of these simple instructions. So most of what you did would be really fast and the stuff you did once in a while would be a little bit slower.

RISC processors also have a lot of registers so you can keep more things in the processor, since you don't have the complex instructions that would do everything at once.

They never really quite caught up with the single core performance of CISC processors though, they have always lagged, and now more than ever. But they are way more efficient. An Intel Pentium D 2.8GHz consumes 171 Watts at idle and 244 Watts at full load, that has two cores. Our 8 core MIPS based networking processor with four threads per core, so effectively a 32 processor system, has a 200 Watt power supply and the processor doesn't get particularly hot (under 65C) with a small heatsink.

It is actually known as a RISC processor, which stands for Reduced Instruction Set Computer. You can find a good description at the source I provided below.

The IBM RS/6000 computer system uses the RISC processor for its systems, and it has proven to be a very reliable and speedy unit. IBM RS/6000 systems use either LINUX or AIX operating system on these servers.

You refer to a RISC processor - which is a type of CPU, such as any made by Intel or other vendor.

RISC stands for "Reduced Instruction Set Computer".
