I'm not too much into encoding/transcoding, but I just came across a new line of codecs Intel is developing called SVT, or scalable video technology. Anyone that's ever done encoding/transcoding through software knows that the process can be long and laborious dependent on the size of the source file and the quality of the output, but despite several hardware solutions that are exceedingly fast, many still prefer to go through the software route for higher quality.
But what if software encoding/transcoding could be done many times faster while still achieving high quality? That's what Intel's SVT hopes to accomplish. As for the performance, I was literally stunned. Intel seems to be leveraging multithread and SIMD optimization to a very high degree to be achieving such framerates. Here are some benchmarks that Phoronix has done to illustrate the massive performance boost versus competing methods:
27 CPUs Benchmarked With AOM AV1, Intel SVT VP9/AV1/HEVC Video Encoders
The Intel SVT-VP9 Performance Boost Across 10 Intel/AMD Systems
I find it fascinating that the CPUs that lack AVX2 in the benchmarks are for want of a better term, simply obliterated! And even AVX-512 makes an excellent showing. In the second benchmark, the Intel 7980Xe is able to be extremely competitive with the Zen 2 Epyc CPUs despite having far less cores, and this is primarily due to AVX-512.
Now my next question is, has anyone ever tried these codecs to see if the quality is comparable to other branches? It must be up to par because Netflix has partnered with Intel and will be using their SVT-AV1 encoder.
