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.
reengineered P6-based microarchitecture used in Intel Core 2 and Xeon microprocessors, built on a 65 nm process, supporting x86-64 level SSE instruction and macro-op fusion and enhanced micro-op fusion with a wider front end and decoder, larger out-of-order core and renamed register, support loop stream detector and large shadow register file.
AMD Zen 4 Family 19h – fourth generation Zen architecture, in 5 nm process. [5] Used in Ryzen 7000 consumer processors on the new AM5 platform with DDR5 and PCIe 5.0 support. Adds support for AVX-512 instruction set. AMD Zen 5 Family 1Ah – fifth generation Zen architecture, in 4 nm process. [6] Adds support for full-width AVX-512 pipeline.
AMD now refers to the codename K8 processors as the Family 0Fh processors. 10h and 0Fh refer to the main result of the CPUID x86 processor instruction. In hexadecimal numbering, 0F(h) (where the h represents hexadecimal numbering) equals the decimal number 15, and 10(h) equals the decimal number 16.
The packages for Arch Linux are obtained from the Arch Linux package tree and are compiled for the x86-64 architecture. Pacman typically uses binary packages with a .tar.zst extension [ 61 ] [ 62 ] [ 63 ] (for zstd compression), with .pkg placed before this to indicate that it is a Pacman package (giving .pkg.tar.zst ); [ 60 ] though other ...

In March 2015, AMD explicitly revealed in the description of the patch for the GNU Binutils package that Zen, its third-generation x86-64 architecture in its first iteration (znver1 – Zen, version 1), will not support TBM, FMA4, XOP and LWP instructions developed specifically for the "Bulldozer" family of micro-architectures.
