I'm not sure how many times we need to debank this myth. I really can't go back in history and outline all AMDs failures for the 100th time.Obviously a tenner and a packet of Quavers is a bit of an exaggeration , but the point stands.
Normies and the general consumer have been told for years that Nvidia is worth any price they ask for because of the extra features that AMD don't have, better performance, better drivers, AMD's bad pricing, the list goes on. The 5070 is 4090 performance, in case you didn't know!
Look at the 5000 series thread, people were queuing up to spend £2500 on a GPU they knew nothing about except it had a billion cores and 32gb VRAM. Now it looks like it might not be the second coming of GPU Jesus, but people seem mainly undeterred.
Even on this thread, on this page, there is criticism of the 9070xt only offering 16gb VRAM, which Nvidia are offering on a £1k (MSRP) card.
All this points to the 5070 being an 'ok' deal. The only noise being made is about 8gb VRAM being not enough, 12gb is more than that and only 4gb less than the second card in the stack, no further thought required.
There is a point at which the consumer gets the market it deserves. This generation needs to be the start of the turning point for both the manufacturer and the paying customer.
AMD used to have equal marketshare to Nvidia and has gradually lost it all. AMD losing their customers is solely on them.
