Pentium's performance relative to the Nx586 and NexGen had difficulty keeping up. Furthermore, PCs identified the Nx586 as an 80386 processor; as a result many applications that require a processor faster than a 386 will not work unless CPU identification software is active.

The company was best known for the unique implementation of the x86 architecture in its processors. NexGen's CPUs were designed very differently from other processors based on the x86 instruction set at the time: the processor would translate code designed to run on the traditionally

It went public in 1994, and was bought by AMD in 1995 for $ 850M. The technology forms the platform architecture for all of AMD's current microprocessors. It was an unusual start-up in its time as the original funding came from corporate investors,
