You cant go by youtube videos, because lack of data, ie drivers, setup being used, bias etc.
while yes drivers do improve performance it does not fix the underlying cause of the issue, lack of memory. even with new crimson drivers people still see issues when at 4+gb.
Shadow of Modor seen performance lost with latest drivers. at 4k Furyx seen around 8 fps lower minimums but roughly the same average fps. So question is that did they counter the framepacing by limiting min frames. So instead of getting a near 40 fps now your getting 30 fps as a low.
How much longer is 4gb fine for 1440p? We are already seeing games allocating beyond 3gb for 1080p, and a few games allocating 4gb or more at 1440p.
Using COD's "fake" vram requirements as a example of vram being over estimated in general is wrong.
I am not going to go by old video and benchmarks to make judgements. Who would you rather use an old data or old videos that show stuttering or newly improved drivers that reduces stuttering and newer videos that shows no more stuttering? Many reviewers have mentioned that the drivers were not up to snuff on many of the review sites and they were still working on driver optimization as communicated by them by AMD and I believe them. I don't see anything to say that stuttering or drivers have gotten worse.
Your theory about counter the framepacing could definitely be a possibility. Only AMD knows what they did to remove stuttering in Shadow of Mordor. That's the only game I have seen stuttering at 4K on the Fury X. Regardless, it was a good thing.
With respect to 4GB at 1440P is more than fine for this year and I would argue even next year. 4K on the other hand I would argue could be an issue with 4GB or even the 6GB of the 980 Ti for this year and next year. Then again I really don't think the 980 Ti or the Fury X can handle every games at 4K with silky smooth framerates, you really need 2X Fury X or 2X 980 Ti to get 4K 60FPS. Problem is that with multi-gpu configurations is that not all games are supported and as you rightly pointed in the other thread where the HD 5970 was losing to the HD 7870 in Arkahm City because it's lack of support for 2 GPU cards like the HD 5970. Which means that your second card could be sitting idle and you would not get the most out of your money. I have never really been a fan of multi-gpu configurations.
As for the COD, I would argue it was an outlier but it was to make a point that just because it uses more VRAM doesn't mean it's not unplayable. I think it comes down to how the memory is managed. That's why even in some games where it takes more than 3GB like with graphics cards like the HD 7970 or the 780 Ti, those games are still playable. Also, with respect to framepacing showing spikes for .001 seconds won't really be noticeable. You are really exaggerating the issue of framepacing. That's why even in games like GTA V where it spikes for a fraction of a second with the Fury X none of the reviewers were complaining that they had noticeable stuttering where it was unplayable as pointed out in my earlier post. Techspot, Anandtech, Tom's Hardware none of them complained about GTA V and the Youtube videos confirms that.
I mostly view the Fury X as AMD doing a testbed for implementing 4GB HBM + using a interposer to lie on the top of the GPU to get experience and technical know how to do develop a GPU using HBM with an interposer. They have done that before with going to new nodes such as the 9600 Pro which was using .13 micron where as the 9700 Pro was using the .15 micron. Also, they did that with the HD 4770 which they used as a testbed to get to 40 nm where as the HD 4850 and the HD 4870 was still on 55 nm. I think this was a smart move. If you look now they already have Polaris GPUs taped out and were demonstrating it at CES. I expect them to be released earlier than Pascal.
They problem I have with the Fury X was that they launched it at the same price as the 980 Ti with drivers that weren't up to snuff. They should have launched it at the price they have now with the driver performance improvements which shows that it's actually ahead of the stock 980 Ti at 4K. And the Fury prices should have been at $500 like they have now. It would have been a much more attractive option. And whose idea was it to include a custom liquid cooler as a standard? It added extra $50 - $80 cost. Not to mention it affected availability as many people weren't able to buy it. They only fixed the issue in Q4 of 2015 and by that time many people had already brought the 980 Ti. They should have a closed loop cooler as an option for AIB partners just like nVidia's AIB partners have done with 980 Ti hybrids.
These are the kind of business decisions that's killing AMD despite them having stellar products.
