The Intel 486, officially named i486 and also known as 80486, is a microprocessor introduced in 1989. It is a higher-performance follow-up to the Intel 386. It represents the fourth generation of binary compatible CPUs following the 8086 of 1978, the Intel 80286 of 1982, and 1985's i386.

The Am386 CPU is a 100%-compatible clone of the Intel 80386 design released by AMD in March 1991. It sold millions of units, positioning AMD as a legitimate competitor to Intel, rather than being merely a second source for x86 CPUs (then termed 8086-family).

The NetBurst microarchitecture, called P68 inside Intel, was the successor to the P6 microarchitecture in the x86 family of central processing units (CPUs) made by Intel. The first CPU to use this architecture was the Willamette-core Pentium 4, released on November 20, 2000, and the first of the Pentium 4 CPUs; all subsequent Pentium 4 and Pentium D variants have also been based on NetBurst. In mid-2001, Intel released the Foster core, which was also based on NetBurst, thus switching the Xeon CPUs to the new architecture as well. Pentium 4-based Celeron CPUs also use the NetBurst architecture.

The Am5x86 processor is an x86-compatible CPU announced in November 1995 by AMD for use in 486-class computer systems. It began shipping in December 1995, with a base price of $93 per unit in bulk quantities. Before being released, it was in development under the codename "X5". Despite the 5x86 name, it is a 486 CPU, and does not implement 586 or Pentium instructions such as cmpxchg8b. It competed primarily with the Pentium OverDrive, which is a true 586 CPU with all 586 instructions.

Zen+ is the name for a computer processor microarchitecture by AMD. It is the successor to the first gen Zen microarchitecture, and was first released in April 2018, powering the second generation of Ryzen processors, known as Ryzen 2000 for mainstream desktop systems, Threadripper 2000 for high-end desktop setups and Ryzen 3000G (instead of 2000G) for accelerated processing units (APUs).
