I was hoping to see some AMD APU in the mix, but still i did appreciate the testing in this article.

If they were serious about it they would add H264 already.
It would make SVT realtime encoding a possibility on a bucketload of CPUs today without eating the CPU to bits as in the h265 case.
So pretty please Santa. With sugar on top. Will you bring H264 to the SVT-suite?

Further, since many times you may only do a 1 pass encoding, such as using CRF or QP modes or CBR encoding, the analysis pass is "folded" in with the encoding pass.
Your tests are very misleading IMHO, all this time I was under the impression that you were testing a single pass encoding scenario, knowing that Intel sped up the first pass makes these results a lot less impressive.

The first pass is the analysis pass, the second pass is the one that does the actual encoding and as anyone that has ever done any amount of encoding knows, it's very common for the first pass of many encoders to be 2-4 times faster than the second pass.

H264 is already covered by HW pretty much anywhere (or achieves "good enough" speed in existing SW, it's hard to beat x264).
x264 is pretty slow, even in crap settings.
But x264 is actually far better of than hardware encoders when it comes to quality.
I would use x264 over hardware encoders if I was encoding data for h264 storage.
But for realtime live streams use on a low power CPU, x264 is just to slow.
Faster options with quality tradeoffs in software is a nice thing to have.
Besides, h265 is patent encumbered in ways h264 is not.
I still maintain that a h264 addon to the SVT suite would be a great thing.
