Erm, no. I'll assume your prices are in £ as IDK current $ prices.I think you are trying to double dip on generational improvement.
Yes, AMD basically shifted the old stuff down a "tier" in price because they had too many and why would anyone buy a $650 6800XT when new stuff that performs just as well is going to sell for $500?
Dropping the 6800XT's price by as much as they did is effectively generational improvement in performance per dollar.
Complaining that the 7800XT is only offering performance that "has been available at that price for a while..." is basically complaining that they didn't double-up on value improvement this gen.
$500 buys more performance now than it did last gen.
Two years from now, I want $500 to be able to buy another 20-30% improvement. I don't care if they sell left over 7900XTX's for $500 or if they offer something with a new number on the box that gives the performance increase. And I certainly won't complain if they do both.
I expect manufacturers to make my money go faster, I don't care about the names they scribble on the box or the status of "next gen" vs "oh that's old stuff".
Does X amount of money buy more performance now than before. If so, how much more?
For me, 30% seems like good progress. 20% is okay-ish.
The 6800 XT is not £650, it's £500. The reason people buy the new stuff is because for that same £500 you get more performance.
No, dropping the price of the 6800 XT by as much as they did is not effectively generational improvement because it should never have cost £650 in the first place, you talk about double dipping but you're trying to have it both ways. You're asking why anyone would buy the 6800 XT at £650 when new stuff that performs just as well is going to sell for £500 but then you go on to say a £500 6800 XT is a generational improvement, you can't compare the £650 MSRP one moment and then the current price of £500 the next.
Two years from now you may want £500 to be able to buy another 20-30% improvement but that's not what you're getting this generation, like i said i don't put much faith in first party data and estimates but as things currently look it seems £500 will get you the same or very similar performance that £500 bought you 2-3 years ago, there is no 20-30% improvement in performance, the £500 7800 XT is going to buy you the same or very similar performance as a £500 6800 XT. That's not an improvement that's stagnation.
Manufacturers are not making your money go faster. X amount of money is not buying you more performance now than before. There has been no 20-30%.
