History
Its second design, the Nx586 CPU, introduced in 1994, was the first CPU to attempt to compete directly against Intel's Pentium, with its Nx586-P80 and Nx586-P90 CPUs. Unlike competing chips from AMD and Cyrix, the Nx586 was not pin-compatible with the Pentium or any other Intel chip and required its own custom NxVL-based motherboard and chipset. NexGen offered both a VLB and a PCI motherboard for the Nx586 chips.
