Vega 64 replacement will be a Navi that is Vega 64 + 50-60-70%.
Once Navi gets a few refreshes we may see some decent improvements but seeing as you like to look at the historical facts look at how Polaris has improved from the 480 to 590 and expect that along side the last historical facts I provided for you. Vega VII won't be outpaced by Navi, That'll come when we get Arturus or whatever they call it.
It's a Polaris replacement yes, but that doesn't mean it'll perform the same. I'd fully expect Navi launched this year to be at least Vega 56 speed, and realistically Vega 64 performance at a price close to RX 590 to be a decent generational jump.
If all we get from Navi is Vega 56 performance and Vega 56 price at a slightly lower power consumption it'll be a massive letdown.
It's either going to have to be a solid performance uplift, or a very good price point. Or preferably, both!
I never said Navi was going to offer the same performance as Polaris I said to expect a similar jump in performance as we saw from Polaris when moving from 28nm to 14nm. We know Navi is still a GCN architecture and we can make an educated guess at what that'll mean for Navi compared to Vega. As I said 7nm Navi may offer 14nm Vega speeds maybe even V64 speeds if we're lucky but it won't match the VII from the top spot & it definitely won't come offering V64 + 20, 40, 60 percent as quoted above, not a chance in hell.
