In 1991 MIPS released the first 64-bit CPU design, the R4000. The design was so important to SGI, at the time one of their only major customers, that SGI bought the company outright in 1992 in order to guarantee the design would not be lost given the financial difficulties MIPS had while building the design. Becoming an internal group at SGI, the company was now known as MIPS Technologies.

Outperforming the [[R6000]] in a compact single chip solution it set an end to it's short and unsuccessful life. The R4000's successor is the '''R4400''' which is virtually identical. Aside of bug fixes and higher clock rate the most significant difference between the R4000 and the R4400 is the cache size. R4000 processors come with each 8kB instruction and data cache while R4400 processors double that to 16kB each cache.
