What is the real reason for these ,is it mining?
Not just mining, but generally the price of everything is on the increase. The cost of production of these GPU's which includes, the cost of acquiring their various components plus transportation, even electricity to mention a few has increased, so you don't expect the price it was a year ago to be the same price currently. You can blame general inflation.
gpu's are cheaper on sept 1 , 2022 than sept 1, 2021
inflation may have caused them to cost more than sept 1, 2020. But mining really ran gpu prices way up all of 2021. Now that eth is destroying itself by switching to pos and off pow gpu prices are far lower.
I can see the op is new and may not follow prices well but a senior person should have more of a grasp on current gpu prices than you do.
I can go to EVGA.com and buy gpus for 30% than I could do last year.
