Not a CPU expert here, but isn't this a comparison of AMD next gen to Intel current gen? Won't Intel have a new CPU out, too, when the Ryzen is actually released?
Seems pretty fair to me.
Intel would need to update their "current gen" (Skylake, Kaby Lake) CPUs with 8-core models to be competitive but for some reason Skylake and Kaby Lake have been stuck with a max of 4 cores... which is why these benchmarks are compared to an 8 core Broadwell.
Intel has been pretty much milking the Desktop Market for as long as they could.
