Your numbers are not accurate when we look at release MSRP. All the GPUs you listed were sub £1000 after adjusting for exchange rates and adding taxes.
1080Ti was $699 on release.
2080Ti was $999
3080Ti was $999 (3080 was the old 1080Ti price)
So NVidia already added $300 to MSRP for the exact same tier of Ti GPU. Now they are trying to normalise $1200 for the tier below this Ti level.
Please don’t fall into the trap of normalising these price increases, that is what NVidia and AMD are hoping for.
You are looking at MSRPS and NOT at what they sold for.
The 1080ti sold for well over £1000 I know... i bought one, i got a great deal on mine for £750 2 years after it was originally released. Thats 2 years after they launched they were only then coming back down around the MRSP level.
MSRPs are pointless if you can't buy them for that price.
Note that i'm not suporting them or those prices i'm just saying that's what they have been and those prices on 10 series and 30 series were both due to a mining boom on both occasions. But they WERE selling for over £1000 that's just reality.
You can't say just because the MRSP was $699 that's what they sold for end of story, because they just didn't, i was there at the time buying one I know what they were selling for on OCUK and other websites and for years they were not selling for MRSPs.
On the basis I paid £750 for a GPU 6 years ago i'm more than comfortable buying my next one for around £1000, a £250 increase over 8 years, with the way the world economy is i'm comfortable paying that it's not "normalising" prices it's accepting that inflation exists.
People do the same with games, people think a game should stay at $60 games have been $60 since 1992 and people now complain MS and Sony are charging $70 adjusted for inflation they would be over $120.
The reality is REGARDLESS of what the MRSP of the previous generations were they were all selling for well over the MRSP, saying the 3080MRSP was the 1080ti price of $699 is a load of crap and you know it, that card was selling for well over £1000 for it's entire run thanks to extreme demand and lack of supply and even now with the 4000 series being released The ONLY 3080 on OCUK right now is £900 (albiet out of stock atm).... that sure as hell isn't the old 1080ti price of $699 that's well over that price when you adjust for.
MRSPs don't matter if they are not selling for that price, i don't understand how that is that hard to grasp.
You can shout from the roofs about how the MRSP of the 3080 was $699 (£570)... tell me then, how the ENTIRE period of it's life when could I go and buy that for MRSP? Even now it's still listed at £900, over £300 above the MRSP.
Don't get me wrong the 4000 MRSPs are a joke, i agree, but so were the MRSPs for the 10, 20 and 30 series, because they were paper MRSPs that hardly ever exisited in the real world through their entire runs.
