Yeah, that DirectX 12 support is super important for when you want benchmarks that show AMD cards are faster than NVIDIA ones. For actual games that people want to play, nobody cares.
Actually I care very much about dx12 games since I usually buy graphics cards every 3-4 years and at times even longer, and im sure many others do the same.
Nvidia is known to perform good on older games and then just go downhill from there, amd focuses on future technology, and have almost always historically had more ram and other features that make them more viable down the road and more future proof, something day 1 reviews cant cover.
Ive said this many times in forums but i will say it again, go and check day 1 reviews for gtx780ti, and compare it to the r9 290 and r9 290x, and then go back and check the most recent review that includes those cards(rx 480 review) and notice how at this point even the r9 290 is beating gtx780ti by a small margin when it was losing by a great margin on release. So go and tell those gtx780ti users that their 699usd investment was worth it 2.5 years ago seeing that a 400usd card is beating it by now(driver optimization/newer games)
Nvidia right now seems efficient because they designed a minimalistic architecture based on what the customer "can do without". Amd on the other hand is feature rich and full of untapped potential (compute, async etc.) and follows an exact opposite methodology of "this feature may become handy so lets add it"
And since you hated the car analogy so much Im Going to bother you with another one right now XD
Nvidia is a stripped out race car with a small focused that only focuses on racing, has no Ac or any added luxury that doesnt contribute to making the car faster down a track.
Amd is a sports road car that has many luxuries and features therefore is heavier, so thet fitted a bigger more beefy engine to make it just as fast down the track, but with less fuel efficiency due to it being a heavier car and more of a balanced all rounder.
There you go
by the end of this thread were gonna be fighting over which is better lambo or ferrari.
