Lol you like reasoning in circles don't you. So going back a full decade is fine, but going back 4 more years is 'jeeezzz you still bring that up'. HD6000 was mentioned...
Two generations? Pascal and Turing, and realistically, also Maxwell's 980ti. It was since that moment that AMD lost leadership definitively and they still bleed for it. During Pascal all they had was a Vega with spotty availability, and a rebadged Polaris card or two that got bought up by miners. Meanwhile, Nvidia could keep channels stocked with a full range of GPUs and ALSO sales from mining. Turing: AMD brings us an RX Navi product that even today is not up to par and still suffers from shit drivers. We still haven't seen the first semblance of a GPU that can do RT. Its not a key feature because the competition doesn't have it, is what you are literally saying. Euhm.... yeah. Surely you can see the problem with that logic, and even so... its still a key feature that AMD is missing, because the moment they also implement it, that is what they are admitting to. You are somehow denying that is true. Nice bit of mental gymnastics.
Furthermore, you can argue all day but the numbers don't lie. AMD is trailing, in technology, in market share and in overall share price, and they are floating mostly on CPU and not GPU, now more than they probably ever have, despite a long term console deal AND a node advantage. Oh yeah! For the gamers!
How is that reasoning in circles? the original posted talked about "the last decade", a decade ago was the HD6000 series release and it did fine in competing and was often the better choice vs Nvidia's GTX500 series.
4 more years is...4 more years, that is not what we were talking about.
Vega 56 like i mentioned was a better option then the nearest Nvidia card and the r9 290/390 was a better purchase then the GTX970.
How did AMD lose leadership, what do you call leadership? having the fastest card out there? orr selling the most because yeah Nvidia has a solid marketing team and legion of fanboys that will always blame AMD for any PC issues (untill recently that included processors as well) and say people should buy Nvidia, and Nvidia is probably like intel properly intrenged with a lot of the pre-build sellers like Dell.
Both companies's cards were bought up like mad by miners during that one period and that rebadged Polaris card, Rx480/580/590 were great cards and again a really good competitor for the GTX1060.
How is RX Navi not up to par..... up to par with what? the RTX2060 Super? because it is....and its often a better purchase, I will give you driver issues, even Gamers Nexus talks about that.
I specifically mentioned not talking about Ray Tracing, you cant seriously claim its important, its not, it will however soon tm and then AMD will have the cards for it and the consoles as well and only BECAUSE AMD will have the hardware ready by then.
Now its not a key feature because only a handful of companies that get money shoved there way are using it, this is like PhysX, the actual proper usage of it was watered down to some extra shenanigans in a handful of games, because nobody would make a game that can only be run on Nvidia cards, the sales would be terrible, again this is why I mentioned console exclusives because Sony for examples PAYS companies to pretty much make up the difference so the game is a console seller.
Likewise nobody seriously has build games fully made with RT because RT is not there yet and 70% of the market out there cant do it, so its just this tacket on feature for most games and not a selling point apart from technerds who love testing this sort of thing.
And that last bit ,you act as if Nvidia invented ray tracing instead of it being in use for what? 2 decades now but just has not been able to be done in real time, Nvidia opened that door (once again I might add) and yeah others will then also with their version of it, heck might be superior and THEN games can be made fully using the tech and we can advance in that area, not prior.
Yep AMD is not selling as much as Big N, I would argue that has more to do with shady practices behind the scenes then anything else, Intel is also still huge even though they do shady stuff as well soooo yeah, welcome to the real world, money makes money and Nvidia has a lot more of it,
Caselabs vs Thermaltake, Thermaltake steals their designs, Caselabs sues and get run into the ground by the infinitely larger company that can sue to infinity, guess Thermaltake is the better company and Caselabs was just not competing or competent....
And obviously AMD currenly invests in what works, they have limited node availability so that goes first and formost to the CPU's that are established and populair.
But to wrap it all up, AMD has a history of excellent videocards that can and does last users for a long time and provide excellent competition, what Nvidia fanboys always conveiniently like to do is just forget all those cards that were the better options in the past and forget all the stumbling blocks big N fell over painting a picture as if AMD always has and had driver issues and big N is perfect, this is just, again, wrong.
