AVX-512 are 512-bit extensions to the 256-bit Advanced Vector Extensions SIMD instructions for x86 instruction set architecture (ISA) proposed by Intel in July 2013, and first implemented in the 2016 Intel Xeon Phi x200 (Knights Landing), [1] and then later in a number of AMD and other Intel CPUs (see list below).
Prime95/MPrime, the software used for GIMPS, started using the AVX instructions since version 27.1, AVX2 since 28.6 and AVX-512 since 29.1. [55] dnetc, the software used by distributed.net, has an AVX2 core available for its RC5 project and will soon release one for its OGR-28 project.
The "Software Guard" is an 8-bit Substitution cipher that, during instruction fetch/decode, translates opcode bytes using a 256-entry lookup table stored in an on-chip Mask ROM. V25, V35 "Software Guard" [38] BRKN imm8: 63 ib: Break and Enable Native Mode. Similar to BRKS, excepts disables "Software Guard" rather than enabling it. MOV r/m,DS3 ...
Beware that older versions of the Intel app note 485 contain some misleading information, particularly with respect to identifying and counting cores in a multi-core processor; [91] errors from misinterpreting this information have even been incorporated in the Microsoft sample code for using CPUID, even for the 2013 edition of Visual Studio ...
Typical applications are digital signal processing and graphics processing. Intel's first IA-32 SIMD effort was the MMX instruction set. MMX had two main problems: it re-used existing x87 floating-point registers making the CPUs unable to work on both floating-point and SIMD data at the same time, and it only worked on integers .
The following is a partial list of Intel CPU microarchitectures. The list is incomplete, additional details can be found in Intel's tick–tock model, process–architecture–optimization model and Template:Intel processor roadmap.

AES-NI (or the Intel Advanced Encryption Standard New Instructions; AES-NI) was the first major implementation.AES-NI is an extension to the x86 instruction set architecture for microprocessors from Intel and AMD proposed by Intel in March 2008.
