I thought it made the point that if you aren't vectorizing your code then it hardly matters if you use an optimized data format. SSE makes a huge difference. With AVX and multiple threads you can actually exceed the memory bandwidth of a CPU socket, which looks funny in performance graphs as adding threads to cores suddenly stops scaling.
