Intel ADX was first supported in the Broadwell microarchitecture. [ 1 ] [ 2 ] The instruction set extension contains just two new instructions, though MULX from BMI2 is also considered as a part of the large integer arithmetic support.
Advanced Vector Extensions 2 (AVX2), also known as Haswell New Instructions, [24] is an expansion of the AVX instruction set introduced in Intel's Haswell microarchitecture. AVX2 makes the following additions:
Below is the full 8086/8088 instruction set of Intel ... Move from 8/16-bit source to 16/32-bit register with zero-extension. 3 MOVZX reg, r/m16 ... ADX Enhanced ...
The x86 instruction set has several times been extended with SIMD (Single instruction, multiple data) instruction set extensions.These extensions, starting from the MMX instruction set extension introduced with Pentium MMX in 1997, typically define sets of wide registers and instructions that subdivide these registers into fixed-size lanes and perform a computation for each lane in parallel.
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).
Advanced Matrix Extensions (AMX), also known as Intel Advanced Matrix Extensions (Intel AMX), are extensions to the x86 instruction set architecture (ISA) for microprocessors from Intel originally designed to work on matrices to accelerate artificial intelligence (AI) and machine learning (ML) workloads.

AMD was the first to introduce the instructions that now form Intel's BMI1 as part of its ABM (Advanced Bit Manipulation) instruction set, then later added support for Intel's new BMI2 instructions. AMD today advertises the availability of these features via Intel's BMI1 and BMI2 cpuflags and instructs programmers to target them accordingly.
Unusually for a "tick", Broadwell introduces some instruction set architecture extensions [17] [18] not present in earlier versions of the Haswell microarchitecture: . Intel ADX: ADOX and ADCX for improving performance of arbitrary-precision integer operations [19]
