not for amd on random generations.
polaris launched at 200$, and that was their top end gou because they forgone higher end models that generation, and opted for targeting the mainstream market. the 580 was just a refresh of it that allocated more of that stock to 8gb models. it was the best selling amd gpu (by far) because they made a lot of them to essentially flood the market.
if youre judging high end by name and by market segment, you have already fell into marketing, as names are completely arbitrary.
200$, even by 2016 standards was not remotely high end. so you couldnt even use it as price.
when the AMD card was on the tier of performace of the 1060, and if THAT is considered “high end” then what is the 70 class gpus. what is the 80 class gpus. what is the titan levels.
when you have 3 distinct tiers above you not even including any possible super or Ti varients of sort, how could you remotely consider it “high end” when you yourself say the 1060 is mid tier.
at a price and performance, the 480/580 is not high end back when it launched, and definitely not high end anytime soon, hence 8gb isnt “high end” in 2026 unless someone has a very short list of gpus they are willing to use. I specifically use the 580 as an example because its actively still being used in poorer regions as the budget card, that actively has 8gb.
