Good guy nVidia, nice.
 
Since the 680 is $499, what do we speculate the price of the 670ti and 670?

670ti around $399 and the 670 around $300 to $350?

Guess I might be holding out till later this year. Not in a hurry to spend over 300 bucks for a video card.

Ok, i'm now confused. TXAA is Kepler specific? Isnt it basically Nvidia's SMAA? We need more info about this from Timothy.

-edit-
Oh my, Timothy's answer

Draker666, TXAA build specially for GTX 6xx is what I'm finishing up right now. I would suggest sending requests for other versions of TXAA through the standard channels at NVIDIA (specifically through NVIDIA devrel or NVIDIA marketing) as I don't have any influence there.

So it basically says that its just exclusive to Kepler, but can be done on every card [like SMAA]. That fucking marketing ;\

No, it has nothing to do with SMAA. SMAA is closer to FXAA than anything else. TXAA is actually closer to Edge Detect AA that AMD had since R600 days.

Do You know that are different forms of SMAA?
SMAA 1x [one that can be used via injector is basically just custom MLAA], but other forms use MSAA resolve, temporal supersampling etc

- SMAA 1x: includes accurate distance searches, local contrast
adaptation, sharp geometric features and diagonal
pattern detection.
- SMAA S2x: includes all SMAA 1x features plus spatial
multisampling.
- SMAA T2x: includes all SMAA 1x features plus temporal
supersampling.
- SMAA 4x: includes all SMAA 1x features plus spatial and
temporal multi/supersampling.

I don't even begin to understand all the different forms of AA. I'm just going to wait for the dust to settle and one superior AA to come out of this war as victor. I will then worship at its feet and bear its children.

SMAA S2TX is godly.

Enjoy, sir.

The victor is already out there SSAA, it just requires an insane amount of processing power.
 
Well, on the Ebay comment I made from earlier, it was based off a forum post someone else had mentioned. I checked out Ebay myself just now, and yes, some cards seem to go up at around $400 but they are closing a lot closer to $500 at the end (7970).
 
So I had a pretty interesting conversation today I wanted to get you guys take on. Long story short, through my job I have a pretty amazing hook up on consumer electronics. I get significant discounts on tv's (Panasonic plasmas) because the guy is pretty high up in his field.

Anyway, I got a chance to talk with him today briefly and we were shooting the shit about the 680 etc etc. So I told him my one issue was with the HDMI 1.4 limitations/120hz. He says that they are on the way, but that plasmas in general are not going to be made much in the future.

The big thing here though is he told me that there are adapters being made, (not yet on the market) that will allow these TV's to accept 120hz from pc's. I couldn't pepper him with TV questions as much as would've liked, but he did seem to confirm the idea that they left off DVI inputs intentionally.

He said the adapter will be in the $100 to $200 range and that he'd get me one and bring in two weeks, so fingers crossed!
 
You can use adaptive v-sync right now on all the other nvidia cards if you extract the 300.99 exe and then replace the ini file.

I am using the adaptive v-sync and fxaa through the control panel, adaptive v-sync rocks. :)

This thing overclocks pretty nicely. With a little tweaking I was able to beat out my best 590 score on 3DMark 11 already! Impressive. Time to sell the old girl.
Link, if anyone cares

SMAA is a post-processing filter which runs independent of AA resolve. SMAA >1x are basically run over an AA'ed buffer and then downsampled (resolved) into a final output buffer. It's still MLAA but with an added benefit of using subpixel precision buffers.
TXAA is a custom MSAA resolve mostly, it's not postprocessing. Details are scarce at the moment but I assume that it will only AA polygon edges and nothing more. In that it's more reminiscent of AMD's Edge Detect AA than anything else.
 
are there any benchmark scores between a

6950 CF setup and a Single 680 and 680 in SLI?

I wanna know if i should sell my CF setup or wait another year.

This is something I've had issue with for some time. HDTVs don't take in a 120hz from any input, and its a shame. Because, things like Side-by-Side (as in the 360 or in PC games like Crysis 2) or Nvidia's 3DTV Play, $40 software that only limits you to 720p60 1080p24 anyway.....have to be used instead.

But I don't see how some adapter will fix this. What I do know is that both AMD's 7000 series, and the 680 both have what AMD calls 'Fast HDMI' (3GHz HDMI), but I wonder what that may have to do with it, if anything.

Actually, recent builds of SMAA have a lot of the features TXAA has (temporal supersampling etc.). But the majority of the features of both can only be used if it's properly integrated by the dev, so I'm happy NV is pushing it.

Hmm, why do you think so? To me, at this point, TXAA seems a lot more like a renaming of what Timothy Lottes was working on as "FXAA 4".

Temporal supersampling is a nice new name for motion blur. You're essentially using your previous frame to construct the next one. This is basically a motion blur algorythm although in case of using it for AA you're dealing with as little motion trails as possible. Still motion blur isn't a feature of TXAA in my opinion because it can be added to almost anything as a postprocessing step.

It does remind of FXAA 4 in it's temporal AA part (which looks to essentially be what Lottes was describing here: http://timothylottes.blogspot.com/2011/04/tssaa-temporal-super-sampling-aa.html). But otherwise it seems to not be in any relation to FXAA 4 because nowhere in his blogs about FXAA 4 did Lottes talk about custom MSAA resolve filter - which is a main part of TXAA:
TXAA is a mix of hardware anti-aliasing, custom CG film style AA resolve, and in the case of 2xTXAA, an optional temporal component for better image quality. The bulk of TXAA is a high-quality resolve filter, which is carefully designed to work with the HDR-correct post processing pipeline.
Also there is nothing about postprocessing in Kepler whitepaper's TXAA part and FXAA 4 is still a post-AA solution which is supposed to be very fast even on today's console hardware.

Yeah I'm not really sure if its a dvi to hdmi adapter of some kind?
 
Silly question.

my current gpu is an gtx 460... and I was wondering... do nvidia cards have hdmi output yet?

This card has 3 monitor support right? Will other 6xx cards have that as well?

Most do, but you do run into some that do not. My 580 eVGA classifieds do not have HDMI, but it came with a DVI-HDMI converter and have had no issues running 1080p/digitla sound to my system.

Yep, it's card specific as others have said. My 460 AMP has 2-DVI ports, 1-HDMI port (runs 7.1 audio just fine) and, 1-DisplayPort.
The card can run dual display but, not triple. You can, however, have all three connected at once then, switch between which 2 you want at any given time.

Even my old GTX260 has 1-HDMI and 1-DVI and does dual display.

I disagree strongly that it's "basically motion blur". The point of the temporal AA in FXAA4 (and, I assume, TXAA) is that the projection matrix is off by one half-pixel each frame, and you use that additional information to anti-alias non-moving edges.
 
So what are people hearing about the 600M series? That's really something I'm most excited for. Smaller, cooler, GPUs that have all the power that you could ever need at the mid-range.

With the 680 being the 104 part and not the 110 part, does this put the mobile 600 series a lot closer to their PC counterparts before?

So should probably avoid the 600M series until they are actually based on true Kepler.

No. Most of the mobile range are re-branded Fermis, and the only mobile Keplers for now are really low-end.
 
Can someone with video card and tech knowledge explain to me why TXAA will have little to no impact on card performance with Kepler? Is it using unused CUDA cores or something?

It will have an impact on performance on the levels of MSAA 2x and 4x. As for the details why it's better suited to Kepler than any other architecture there are no solid details on the TXAA algorythm at the moment.
 
So does it seem unlikely that these will come back in stock within the next week?

I have heard early April - which means it could be another week. Just keep checking. I had the same issue when the 7970s launched - so while at work I just F5'd the NewEgg section where they're stocked and within a couple days of doing so I was able to snag one.
