x86-64 (also known as x64, x86_64, AMD64, and Intel 64) [note 1] is a 64-bit extension of the x86 instruction set architecture first announced in 1999. It introduces two new operating modes: 64-bit mode and compatibility mode, along with a new four-level paging mechanism.
Intel's second generation of 32-bit x86 processors, introduced built-in floating point unit (FPU), 8 KB on-chip L1 cache, and pipelining. Faster per MHz than the 386. Small number of new instructions. P5 original Pentium microprocessors, first x86 processor with super-scalar architecture and branch prediction. P6
AMD Zen+ Family 17h – revised Zen architecture (optimisation and die shrink to 12 nm). AMD Zen 2 Family 17h – second generation Zen architecture based on 7 nm process, first architecture designed around chiplet technology. [3] AMD Zen 3 Family 19h – third generation Zen architecture in the optimised 7 nm process with major core redesigns. [4]

Intel SHA Extensions are a set of extensions to the x86 instruction set architecture which support hardware acceleration of Secure Hash Algorithm (SHA) family. It was specified in 2013. [1] Instructions for SHA-512 was introduced in Arrow Lake and Lunar Lake in 2024.
IA-32 (short for "Intel Architecture, 32-bit", commonly called i386 [1] [2]) [3] is the 32-bit version of the x86 instruction set architecture, designed by Intel and first implemented in the 80386 microprocessor in 1985.
Intel microcode is microcode that runs inside x86 processors made by Intel.Since the P6 microarchitecture introduced in the mid-1990s, the microcode programs can be patched by the operating system or BIOS firmware to work around bugs found in the CPU after release. [1]
