Interesting to finally see first generation DX11 hardware going into EOL support mode. Personally, I see DX11 and 64-bit as the new baseline minimums, so AMD stating that it's actually less tham minimums in their book is interesting to me.

AMD doesn't have the cash flow that Nvidia does to support their older hardware. Plus they arn't back porting DX12 to HD5 or HD6 series cards, so that may be their logic.

Hold on a second partner, nvidia may support the older hardware, but they no longer optimize for it after it is no longer their current series. There are countless stories of cards from nvidia starting to perform worse upon installing the first driver that supports the cards replacing them. Amd has genuinely been optimizing these old cards where nvidia just makes sure older cards will work with very little to no care for performance increases once a newer series comes out. Often they are okay with significant hit to performance.
