AVX or Advanced Vector Extensions are future extensions to the x86 instruction set architecture. Upcoming future microprocessors, such as Intel’s Sandy Bridge and AMD’s Bulldozer, will support these extensions and provide new features and a new coding scheme. With AVX, the size of SIMD vector registers are now 256-bits (compared to 128-bit in SSE2). Sandra 2011 added support for these changes, introducing a benchmark that uses variable numbers of threads depending on CPU type and system topology. Unfortunately, these processors haven't been released yet so we cannot show any tests that take advantage of AVX or FMA.
