That's what we don't know. Usually early leaked figured for a new microarchitecture are for the flagship release. For NVIDIA, they always that splash with the "80" card: GTX 1080, GTX 980, GTX 780, GTX 680, GTX 580, etc. Ultimately, that won't be the fastest release on the microarchitecture, since they'll refine it with the 1080 Ti and Titan releases, but that's the usually the reference for the microarchitecture as a whole when it is debuted.
I think most of assuming that about this Vega card, and this will be the first true generational leap in terms of technology.
Oh, I think he's just talking about the marketing circus AMD does their best to invent around any new release. It's irritating when they hype CPUs like the FX-9590 that was literally little more than a pre-overclocked FX-8350. They've done that shit more than once. He's probably thinking of stunts like the AMD employee
accidentally "exposing" a screen with OC results that just have no relevance for the mainstream market even if it wasn't a bullshit score that only maxed a single thread (because the mainstream isn't using de-lidded processors on nitrogen-cooled test benches for PC gaming). So there they are trying to get people talking about 5GHz overclocking due to raw potential, and since that time, the community appears to have determined AMD themselves built in some sort of voltage governor that prevents Ryzen from overclocking beyond the 4.1 GHz wall in the real world.
Of course, with Ryzen itself, that criticism against AMD isn't as compelling, and if Intel actually had a rabbit in their hat to hype, they would have done the same thing. It's wouldn't be wise for them to stir up market hype around Kaby Lake. How would that go? I'm reminded of the scene with Christopher Guest's rocker character talking about how Spinal Tap's shows are the loudest in the land because their custom speakers' volume dials "go to 11". That pretty much would have been Intel's marketing campaign for Kaby Lake. "And check out our new processors...they have a 7 in front of them! Brand new shit!!"
