The i686 architecture is fully backward-compatible with the i386 architecture, meaning that any software that runs on an i386 system will also run on an i686 system.
i686 is the 32-bit version, and x86_64 is the 64-bit version of the OS. The 64-bit version will scale with memory better, particularly for workloads like large...
It is frequently referred to as i686.[2] It was planned to be succeeded by the NetBurst microarchitecture used by the Pentium 4 in 2000, but was revived for the...
Örneğin: Intel Pentium, Intel Core2Duo, AMD K6. ix86 yıllardan beri var, 2000'den sonra bir işlemciniz varsa, muhtemelen en azından i686 komut setine sahip.
But what exactly does it mean? In this overview, we’ll dive into the details of what makes an i686 CPU unique, and how it differs from other types of CPUs.
