Intel Advanced Vector Extensions to debut in September

Intel announced a couple years ago that it was working on a new set of vector extensions as a superset of SSE, Advanced Vector Extensions or AVX. Now Paul Taylor is reporting that it will get its official debut at IDF in San Francisco this fall

This actually means that code execution efficiency should go up a bit, as well as providing some nifty floating-point juggling that will accelerate multimedia operations considerably, according to Intel. AVX is also said to cater to CPU parallelism and power efficiency – two driving forces of today’s CPU development. Increasing the scalability of parallel computing apps – something that will definitely appeal to the HPC crowd.

AVX will show up in Sandy Bridge, which is also set to debut at IDF this fall.
