To put this claim into perspective, Nvidia has had a card of comparable speed on the market for 14 months, which consumes 40% less power than RX Vega (GTX 1080).
The price is definitely attractive, but we're comparing it to year-old units from nvidia. Throw into the mix the fact that NO graphics card is selling for MSRP and hasn't for the last 6 months, you can expect supply and price to be far from this mark.
I just can't see this being a compelling business model - release late, under performing and cut margins to make up for it.
I love team red, and I have owned AMD cards for the last 7 years (one of which mined 50+ bitcoins on it's own) but this latest showing is quite late and quite lackluster. I can see nvidia releasing volta in the coming month or two, giving them a strong lead in performance and efficiency, and slashing their pascal card prices to vega level.
AMD is keeping nvidia on their toes, and for nothing other than that, we should support them. It would be nice to be doing that AND having the fastest hardware.
