The reason i say this is because Intel still need to build monolithic dies for high core count CPU's, which yields very low results from wafers, that is a real problem in the industry and so far only AMD have the technology which gets around it.
With that this very solution is also more efficient than Intel's Mesh given that the IPC on Ryzen 2### is around 10% higher than on Skylake-X, actually about even with Coffeelake, so AMD's Infinity Fabric looses less IPC than Intel's Interconnect Mesh from standard Ring Bus type interconnects, or since AMD no longer do a Ring Bus type interconnect Ryzen's IPC may just be higher and the loss has simply brought it down to in-like with Coffeelake.
AMD's Infinity Fabric is better than Intel's Mesh and the Ring Bus doesn't afford Intel higher IPC over AMD
Intel do have the processing advantage, 14nm Coffeelake clocks higher than GloFo 12nm, that's true, for now, but its looking like Intel will lose that too once TSMC / GloFo 7nm hits.
