we recently bought Intel® Parallel Studio XE 2015 which has IPP 8.2 version. we are using them with Intel samples for G729 speech codec. I tried using intel 8.0 samples and Intel 6.1 samples. Both of them are not giving better performance than our own implementation. we also have IPP of 6.1 version which is giving better performance than 8.2.
I linked 6.1 G729 samples with 6.1 version and 8.2 version of IPPs out of both 6.1 version gives better performance.
IPP 6.1 version linked with 6.1 version sample avg per/frame encode time: 21 microsec
