That's a lot more then "slightly higher performance", it's almost an entire tiers worth. It's what the 4070 should of been on release and not all those watered down models they were trying to pass off. Price seems a bit much but remember we've had 10~25% inflation the past few years, everything's price is up.
Out of the entire range, this is the only model that is worth purchasing so far.
Well I mean I spent $155 for a dual core Opteron 165 in 2007, the entry level model, and in 2024 you can get a quad core 14100F, the entry level model, for the same price, twice the cores for the same price. Also in 2007 I spent $118 on 2x512MB DDR-400, and in 2020 I spent $125 on 2x8GB DDR4-3200. 16x the capacity for effectively the same price.
In contrast, In 2013 I paid $433 for an XFX 7970 Ghz Edition, AMD's flagship of the time. In 2024 you're looking at $1000 for the current flagship model, twice the price. In 2004 I spent $174 on a Radeon 9600XT, a great midrange card of the 9000 series, and in 2020 I spent $520 on a 2070 Super, again a great midrange card of the 2000 series, well over twice the price. In 2009 I bought an ASUS Crosshair III Formula for $200, a flagship AM3 790FX motherboard, and in 2021 I bought a Gigabyte X570S Aorus Master for $390, a flagship motherboard.
In the realm of computers, the only two core components which have drastically increased in price are motherboards and GPUs. CPUs have gotten more expensive, but they also have more cores. My 5950X (that I loathe) cost $548, 3.5x the price of the Opteron 165, but on a per-core basis it cost $34.25 per core vs the Opteron's $77.50, so on a per-core basis they've actually decreased in price over the last 20 years. Motherboards have gained a lot more functionality and, especially on the AMD side, have many more models with the highest end chipset on more affordable models (the ASUS TUF GAMING X670E-PLUS WIFI 6E, for example, is $280, only 50% higher than the board I bought in 2009 and in line with inflation exactly). Compare this to GPUs where the $433 spent for a 7970 Ghz Edition in 2013 equates to $566 today, the price of some 7800XT, a lower tier model.
Sure GPUs have gotten more complex with many times the number of transistors and processing capabilities, but they've also increased in price far more than any computer component in the last...15 years? And they're going to keep increasing as long as there's a cooperating duopoly because they don't have to sell any consumer GPUs, they're making money hand over fist selling enterprise cards for many times the profit margin, and they know that whatever they price consumer cards at people will buy them because eventually you WILL need one, and you WILL buy one even though you will grumble about the price for years.
