The Radeon RX 6600 is not even 3 years old, not to mention it was impossible to get any GPUs during that time so it might as well be only 2 years old.
And yeah the 2060 will be 5 years old in January but if we look at something like Steam’s hardware survey, it took until this month for the 3060 to become the “top dog” on the steam survey. Which is still only 6% of people, prior to that it was the GTX 1650.
