AVX stands for Advanced Vector Extensions, an extension to support chipsets with x86 architecture (for both Intel and AMD), initiated by Intel in 2008. This extension was first available. on the Sandy Bridge processor introduced by the company at CES 2011.
If you often hear Intel Core i3, Intel Core i5… then Sandy Bridge is an earlier computer CPU, called Intel Core i2 (2nd generation Intel). Although today, this processor is "old" but at the time of launch Sandy Bridge was 42% faster than its predecessor, the ability to support gaming increased by 50% with the AVX extension.

What is Intel AVX-512?
Intel AVX-512 is an extension to support chipsets with x86 instruction sets but their accumulator registers are 512 bits, first implemented on Xeon Phi x200 chipsets released in 2013 and more recently especially on Ice Lake (10th Gen Intel) and Tiger Lake (11th Gen Intel) chipsets.
With double-width data registers compared to its predecessor, AVX2, improved Intel AVX - 512 reduces latency, further accelerating when encountering heavy tasks, handling workloads well. large, the task that requires the most exacting calculations.
What technologies are improved on Intel AVX-512?
Here are the improvements that go beyond its predecessors, partly confirming that Intel AVX - 512 is an indispensable part to improve performance in today's Intel chipset technology.
Accelerated storage functions: encryption, compression, decompression
Intel AVX-512 helps the data bus in the CPU more efficiently use the resources and data already stored on this extension. In a word, it helps to speed up data storage functions, making encryption, compression and decompression faster.

Some of the performance that Intel has delivered when computer CPUs equipped with the Intel AVX - 512 extension have 1.63x faster encoding, compression and decompression, machine learning modes and AI 2.2 times faster than AVX 2.
The processing of compression and decompression algorithms is optimized to reduce the performance of the decoding process. Also, when data is deployed using a non-distributed data environment, there will be no impact on overall performance.
Significantly upgraded workflow performance
Intel AVX-512 helps to organize and process the set of files optimally. The cases where Intel AVX - 512 is used a lot are: quantitative financial analysis, artificial intelligence (AI), machine learning mode (deep learning), building models, 3D analysis, processing image, audio/video, encryption and data compression.
The ability to process twice as much data with a single instruction
Intel AVX-512 enables twice as many floating point operations per second (FLOPS) per clock cycle than its predecessor, Intel AVX2. A single register in the Intel AVX-512 can hold up to eight double-precision floating-point numbers or 16 single-precision floating-point numbers.
In other words, Intel AVX-512 allows processing twice as many data elements that Intel AVX or Intel AVX2 can handle with a single instruction and four times as many SIMD Extensions online ( SSE).
Intel AVX-512 increases register width 16 times over original 32-bit registers and enables FLOPS enabled by Intel AVX2 to be doubled
So what processor (CPU) is Intel AVX - 512 available on?
Intel AVX - 512 has appeared since 2013, appearing on many Intel processors. Below is a summary of outstanding CPU models that are all equipped with the AVX - 512 extension, for your reference.
Xeon Phi x200 and Xeon Phi x205

Intel AVX-512 was first introduced by Intel and featured in its Intel Xeon Phi and Xeon Phi x205 processors, commonly known as Knights Landing and Knights Mill.
Skylake-SP, Skylake-X
These two chipsets launched in 2015, are manufactured on the 14 nm manufacturing process. In addition to being equipped with Intel AVX - 512, thanks to the Broadwell architecture design, it helps to increase performance and reduce power consumption much more than its predecessor.
Cannon Lake
Cannon Lake was released in 2018, with a CPU core of AVX - 512 and applying Intel's first 10 nm process technology. These improvements contribute to an increase in processing performance by more than 15% compared to its predecessor.
Cooper Lake
Cooper Lake is the big successor from Cannon Lake released mid-2020. This CPU also has the AVX - 512 extension, adding a big improvement that is faster memory support (DDR4-3200 vs DDR4-2933 )
Ice Lake and Tiger Lake
Ice Lake and Tiger lake, respectively, are Intel's new CPU names, the 10th generation Core and the recently launched 11th generation Intel Core, for thin and light laptops. With the Intel AVX - 512 extension equipped, the performance and speed of computing and data processing on these 2 CPUs are definitely optimized in the most efficient way.
