x264 supports encoding 4:4:4 (i.e. no chroma subsampling) video. There's some very obvious cases where it produces better results, but it's typically just slower with no upside.

The GP is talking about using 4:4:4 but having lower bitrates for chroma channels than luminance

That is still slower than subsampling.

But it can produce a result which looks better at the same bitrate. It’s not all about speed.

"but it's typically just slower with no upside" was the original statement.
