I will quote my other post:
"So doing some digging. Looks like RDNA is a "Hybrid" design that bridges GCN to RDNA... Just like VLIW4, but more extreme.
Lots of changes under the hood, but it's still very easy for developers to leverage it if they have worked with GCN for a long time.
The doubling of the ROPS is a big boost... And one bottleneck of GCN gone. - Reducing wavefront size and increasing SIMD size so they match is another big Pro' as well and another GCN bottleneck gone.
Uplift in bandwidth and chip-wide delta colour compression and much improved caches resolves another GCN bottleneck.
It's going to result in a substantial uptick in performance per teraflop either way... I would not be surprised to see a 50% performance uplift over the RX 590."
Things like Primitive Shaders are now working as well, finally.
As for Vega... Vega was actually extremely efficient, at lower clocks and voltages, AMD though wasn't able to compete though and decided to throw out efficiency in order to garner as much performance as possible.
Just remember though, Navi is Polaris's replacement, not Vega. Vega 7 will still be AMD's high-end part going forward.
And if we can... Try and stick to better sources than Polygon, like Anandtech.
Fixed it. Just wanted to link to some basic info on it. But I like Anandtech's tables better.
I know Vega could be undervolted, but the best Vega card I could find was excessively long, to the point where it needed a brace. And there were quite a few reviews complaining of game crashes.
What I really wanna know is if RX 5700 will become as popular as 580/590, or if it will be another Vega. I almost never see builds using Vega.
Vega as a GPU just wasn't worth it. I think HBM just kept the price up to high to make it a decent price/performance option for most.
Often it was cheaper to just get two RX 580's and throw them into crossfire. (Although crossfire drivers are hit and miss these days, which is a caveat.)
Polaris however was always fairly cheap (Except during the crypto-boom) and it was a great GPU for 1080P-1440P gaming.
The RX 5700 XT's success really depends on price... Because AMD isn't giving us stuff like hardware ray tracing with this part, so nVidia has a value-incentive advantage on that front.
