Nope. TXAA is MSAA with temporal filters on top. Games that can't support MSAA also can't support TXAA. If MSAA is dead, so is TXAA. Maybe you meant to say TAA, which is post-process temporal AA. It's not bad at 4K. It is a bit blurry, but at this point, it's the only thing that gets rid of shimmering, so I'll take it.

Probably a smart move on Nvidia's part but also on AMD's to use HBM2. If you look at what Vega is and what Navi is planned to be, the HBM2 plays a big role in there plans so AMD has to push forward with it. Vega is a SOC with there infinity fabric implemented. I very much expect with the 7nm Navi planned for next year we will see AMD take a Ryzen like approach and start "gluing" GPU's together to function as one unit with no need of crossfire and the driver profiles that go with it. They will have very high bandwidth needs when they start sharing the HBM2 across multiple GPU's. I'm not certain but pretty sure this is why they designed Vega the way they did so its a stepping stone to a die shrink and use the infinity fabric to tie more than one GPU together, well and also to make APU's easier.

Really when we start to push 4/5/8k in games in the future we wont need any more AA, it made a lot more sense in games that were 1080p and below when the edges were still rough and more blocky. These days even me running games at 1440p, i find that AA isn't that needed and with the future going towards higher resolutions suck as 4k+ i think AA might just stop being a thing, or at least something that is not needed as much

Screen size have big matter. Even at 4K+ AA is good to have. There is 4K 27", and there is 4K 65". Well I can agree 27" will dn't need any type AA. But same rule will not work for (lets say) 50" coz there are benefits using 2/4 MSAA. 8K its extreeme sport right now 🙂

If i was Nvidia i'd wait for GDDR6 for Geforce Volta cards, especially the xx80/xx70. The rest i don't care about if they have GDDR5/X but for Volta enthusiast cards they should use GDDR6. Why? because i believe GDDR6 will be a good selling point.

I was under the impression that 4K doesn't really need much AA. I'm sticking with 1080p/1440p for at least another 2 years anyway so doesn't matter for me.

It's probably cheaper, plus AMD has been working with HBM for awhile we know. Nvidia still is probably getting their feet wet with it. Kind of reminds me of a certain war between two optical storage formats just a few years back...

Since 4K will obviously be the target for the upcoming Volta cards, NVidia had better optimize memory I/O even further if they stick to GDDR. MSAA seems to be dead, so they will probably get away with this just fine.

I wish FXAA would go find a quiet corner to die in.

No point in using anything but GDDR5X. May as well save money and costs for everybody including Nvidia. If the memory is fast enough for the next series....may as well keep it. Just because something doesn't say GDDR6 on the next card does not mean it wont be worth while.

Yeah, the AMD put themselves in the corner with HBM. On one hand it's a great technology, but it still requires time to bring down cost. On the other hand, if they as the creator, ditched it all toghether, I really doubt anyone would ever cared for it. That's also why they don't collect royalties on it, even though they own most of the patents for it. Also, I don't think that AMD has enough money to split their chip design for two different types of memory with different MC. So it will probably be a few years untill the AMD will really see a benefit of HBM, at least with gaming cards.

Memory has to get closer to the cores to get the pJ/bit down. AMD is ahead of the curve with HBM, even though using it isnt strictly necessary for some GPUs. Nvidia knows that, which is why their P100, V100 and Quadro GP100 all use it. Its also why every pre-exascale supercomputer architecture i can think of uses some form of advanced memory, be it HMC or HBM. Processor in memory(PIM) is also taking off.

Increased framerates when you run out of VRAM is not something I'd consider must have - just give the card enough VRAM in the first place. Regardless, I think everyone knows HBM2 has benefits, the question is whether those benefits is worth the increased cost, potential delays, etc that seem to stem from using it. In gaming, I personally don't see the value.

Given that nvidia have been smashing amd in the performance department for about 15 years straight...

msaa by itself is useless with modern rendering.. Unless it's used as part of a bigger technique, then it should stay dead. At least FXAA doesn't introduce horrible artifacts into the image (or smear it into oblivion as soon as there is movement. FXAA has a slight softness, most TAA flat out makes the image smudgy without a ton of SSAA on top)like many TAA solutions do. With oversampling(SSAA/downsampling) the negative effects of FXAA are completely invisible. SMAA 1x does not really do a better job than FXAA at 1x res aside from a sharpness advantage. It is equally as bad at subpixel information. And again with SSAA on top, there is almost no difference between the two.

Given that nvidia have been smashing amd in the performance department for about 15 years straight...I don't think this will be a problem. If the price to performance ratio is off then I will wait longer to upgrade but given that I am gaming on at 4k with a 1080ti at 60 frames in almost all games, I don't think the memory bandwidth will be a problem...although it clearly resonds better to overclocking performance incease than core clocks.
