AVX
Advanced vector extensions (AVX) were first introduced in the second-generation Sandy Bridge CPUs in January 2011, and are also supported by AMD's Bulldozer processor line. SSE has a new 256-bit instruction set extension called AVX, which includes 12 additional instructions. Image and video processing, scientific simulations, financial analytics, and 3D modeling and analysis are just a few of the applications that benefit from AVX. Windows 7 SP1 and later editions, Windows Server 2008 R2 SP1, and Linux kernel versions 2.6.30 and higher all support AVX. For virtual machines running on Windows Server R2 that support AVX.
AVX 2.0 was released in connection with Intel's fourth-generation Core i-series Haswell CPUs in the spring of 2013. AVX 2.0 introduces 30 additional instructions and improves both floating-point and integer speed when compared to AVX.
Although AMD had previously implemented Intel SSE3 and earlier instructions, instead of adopting SSE4, the company has developed a new set of only four instructions known as SSE4a. Despite AMD's plans to develop and distribute its own instruction set named SSE5 as part of its new Bulldozer processor architecture, the company opted to postpone SSE5 in favor of new instruction sets that employ AVX-compatible coding. The new instruction sets include the following items.
- XOP—Integer vector instructions
- TMB—Trailing bit instructions
- FMA3, FMA4—Floating-point instructions
- BMI—Bit-manipulations instructions
- CVT16—half-precision floating-point conversion
Bulldozer CPUs support XOP and FMA3, whereas Piledriver adds support for FMA4, CVT16, TMB, and BMI.
