It's virtually identical but offers slightly faster floating point performance. The only workstation vender to use the R4700 was Siemens-Nixdorf in a variant of the [[RM 200|RM 200 C]] workstation. Linux supports the R4700 but this hasn't actually been tested since several years.

-The '''R4600 Orion''' started shipping in 1994 as the first microprocessor developed by [[Wikipedia:Quantum_Effect_Devices|Quantum Effect Devices, Inc.]] in collaboration with [[Wikipedia:Integrated Device Technology|Integrated Device Technology]], Toshiba Corporation, and NKK Corporation. R4600 implements the [[Instruction_Set_Architecture#MIPS_III|MIPS III]] instruction set in a simple but effective 5-stage pipeline.  It's very similar to the [[R4000|R4000 and R4400]] processors but unlike these there is no integrated second level cache controller.

R4600 has 16Kb Instruction and 16Kb Data L1 caches like R4400, but it is two-way set associative (as opposed to the R4400 which is direct mapped). Cache line size is fixed at 32 bytes.
