RDNA is just a different way of looking at data on a video card - not like it's any different at all from any other piece of silicon. The custom form factor SSDs are ridiculous... Will end up with both of them, but not at launch.To be honest, the high price is not unexpected since its using the more cutting edge technology even at this point in time. Things like RDNA2 is not even open to public sale, and the consoles are the first to get it. Also the use of customized NVME SSDs will also boost the prices over previous gen models all using slow mechanical drives. Yet despite the rumored prices, it is still decent as compared to a laptop/ mini desktop with somewhat similar specs.
Absolute performance is all that matters - "Yeah this card sucks, but it was really really cheap".With the high performance of the GPU, at launch it'll be far better value for money than any mini-desktop at a similar price.
I'm a PC gamer myself, but I'm always envious of the performance per dollar a console can provide.
