Ok...So, I take a look at the single threaded performance and I see a 20% gain of AVX2 compared to SSSE3.
It is really amazing that the remaining non-optimized parts of the algorithm can impact the performance around 80% (!)
Does that mean that all these months of writing optimized AVX2 assembly are really contributing for 20% ?
I would really like to hear what the dAV1d team or other developers of software AV1 decoding say about that.
Do we really have an 80% non optimizable algorithm here ?
Looks like another implementation of Pareto law to me.
