interesting arguments here. For one you have FLOPS as a measurement of performance on the other you have some HP analogies.
the funny thing is if you combine those two you get a different story entirely.
If you take a chevy, a ford, a toyota, a bmw, ferarri, porche, bugatti, suburu, and a mercedes and bring them all to the same HP rating at the same rpm, would you really expect them all to have the same performance?
Ie the same 0-60, the same quarter mile, the same times around the nurnburg ring, the same time on a dirt track, the same finish in the Datona 500, etc...
No you certainly would not. Not at all. And that's not even taking into account model and design from each of those manufacturers ie trucks, performance cars, family sedans, etc. Plus within each of those categories you have more specific differences.
So with all due respect to Dave, I feel his argument is about as weak as it gets. After all he IS a mobo reviewer, doesn't he take a look at boards with the exact same chipsets? Or do features not matter? because last I checked board prices for a specific chipset have several hundred dollars between lowend and highend for that same chipset.
architectures do better in different environments using different features, shading, tessalation, vr, 3d vision, FOV, Lighting effects, etc.
so I can't imagine why you would have a beef of making the FLOPS identical and running a few benches to see how each handles those different features. It would be no different than pretty much any comparison Top Gear (with the big 3, Clarkson, Hammond, and May) has done time and time again. They got 3 nearly identical spec vehicles and put them through their paces expecting different results. Were they crazy? well maybe they were but not for that reason.
Will the same performance make it the exact same arch? Of course not. But will it be interesting and entertaining? F yes!
