GCN is limited to 64 CU, so the only way to get Navi faster than that is to clock it faster. To reach 14TFlops almost 2Ghz would be needed, way too much for GCN.
Radeon VII is able to beat the Vega 64, but for this you would need a chip that beats Vega VII while just consuming less then half of it. That's just not feasible short of a wonder on Navi.
And don't worry, I took chip prices in the next year into account when I said it's going to cost twice those 500$ in production. CPU/GPU ( possibly combined in an APU, but I doubt it) alone will not come cheap as their footprint is much higher than on this Gen. The larger the chip, the higher the price, exponentially so in fact. An APU with Zen2 and Navi with 64 CU will be at least around 500mm2 in 7nm, way too expensive to sell for under 400$ a chip (in 2 separate chips a somewhat lower price is possible to get). The APU in the PS4 and the Pro is only around 250mm2, so just one quarter of the size (don't forget it's squared) that the chip in the leak would take, in fact the GPU alone would be larger than that.
Add to this 24GB not-yet-released (and thus more expensive, at least early on) GDDR6 Memory (GDDR6 is based on DDR4 btw), even with the dropping memory prices that will be around another 100$ for sure early on. Add all the other components, assembly and shipping, and you're getting close to 1000$ even without paying consumer prices.
