Embedded systems and general-purpose computers used x86 chips before the PC-compatible market started, [b] some of them before the IBM PC (1981) debut. As of June 2022, most desktop and laptop computers sold are based on the x86 architecture family, [5] while mobile categories such as smartphones or tablets are dominated by ARM.
However, on the x86-64 platform, many x86 applications could benefit from a 64-bit recompile, due to the additional registers in 64-bit code and guaranteed SSE2-based FPU support, which a compiler can use for optimization. However, applications that regularly handle integers wider than 32 bits, such as cryptographic algorithms, will need a ...

Descendants of the x86 IBM PC compatibles, namely 64-bit computers based on "x86-64/AMD64" chips comprise the majority of desktop computers on the market as of 2021, with the dominant operating system being Microsoft Windows. Interoperability with the bus structure and peripherals of the original PC architecture may be limited or non-existent.

AMD introduces its Opteron and Athlon 64 processor lines, based on its AMD64 architecture which is the first x86-based 64-bit processor architecture. Apple also ships the 64-bit "G5" PowerPC 970 CPU produced by IBM. Intel maintains that its Itanium chips would remain its only 64-bit processors. 2004
The common usage of MS-DOS unified the x86-based systems, promoting growth of the x86/MS-DOS "ecosystem". As the non-x86 architectures died off, and x86 systems standardized into fully IBM PC compatible clones, a market filled with dozens of different competing systems was reduced to a near-monoculture of x86-based, IBM PC compatible, MS-DOS ...
