What is avx 2.0?

AVX 2.0 (Advanced Vector Extensions 2.0) is an instruction set extension for processors designed by Intel and introduced in 2013. It is an improvement over the earlier AVX instruction set and provides optimized routines for vectorized math, data processing and scientific computing applications.

AVX 2.0 doubles the width of the registers to 256 bits, thereby increasing the capacity to handle twice as much data as the previous version. It also introduces new instructions for 256-bit floating-point arithmetic operations and gathers and scatter operations with 32-byte aligned memory operations. This results in faster and more efficient processing and better performance in a wide range of applications including scientific simulations, financial analysis, image processing, and machine learning.

AVX 2.0 is supported on Intel's 4th Generation Core processors (Haswell) and subsequent processors, as well as some AMD processors. However, its use requires software that is specifically optimized for it, and not all software applications may benefit from it.
