Nvidia Kepler - Geforce GTX680 Thread - Now with reviews

Yeah, I'm talking about the HDMI limitation, not the display. Anyway, I guess we'll see.

HDMI can only output 60hz. If you are watching it in 3D, that means it's limited to half of it's total output, 30hz. To get true 120hz, you need displayport or DUAL LINK DVI, not to be confused with DVI-D.

I know all this, and that's why I questioned how this adapter Jtrizzy mentioned could work at all. It's always been a wonder to me why 120/240hz HDTVs didn't have Display Port for Dual Link DVI inputs in the first place. I've mentioned this in more than one thread. It would have solved a lot of issues before they even came about, and we wouldn't need the $40 Nvidia 3DTV Play software (still limited to 720p60/1080p24) at all.

Additionally, when the 7970 came out, a number of reviews mentioned (I specifically remember Anandtech for one, but I'm sure a few others did as well) that the HDMI port supported what they called Fast HDMI (3Ghz). This would alleviate the previous limitations of HDMI, and that future 3DTVs would support this. The GTX 680 also has this.

But you've said something that puzzles me, maybe I've gotten this wrong all along, so maybe you can explain. If I'm watching in 3D, the HDMI is limited to 30hz.........what? Isn't the HDMI running at 24hz when I'm watching a 2D Blu Ray? Or do you just mean a maximum of 60hz?

HDMI can run 60 hz max. That in 3D means 30 hz for one eye. 2D Blu-Ray movies are 24hz because that's how things are with movies(60 fps soap opera argument)

Lots of questions to answer.

HDMI was created using the same electrical signaling as single link DVI-Digitial with integrated audio. Display port was not spec'd and was designed for high resolution use in computers. Original hdmi cables are limited to 1920x1080 interlaced at 60Hz or less. In order to accommodate the extra bandwidth of 3D they either needed to increase bandwidth or lower quality. They did both and introduced High speed hdmi can support full 1080p at 60hz and 4k or 3d at 30hz or less. There are not enough signal cables in the HDMI spec to support any more bandwidth so you will never see anything higher then 1080p 3D at 30hz

Since it is based on DVI there was no need for DVI on TVs as a simple passive adapter can be used. Dual DVI was never used because it would add a lot of costs to the signal processing hardware and would see little or no use and does not include audio.

I made that other one for all the dvi specs. I need to dig that one up. I think I'll write up a post for the pc thread about all the differed cause it seems to confuse most people.

Thanks for the post. Most of that I already knew, its just the 60hz limitation that got me, I was starting to think what I thought I knew was wrong.

Either way, in an effort to get this thread back on subject, the reason I asked all these questions about 3D and HDMI in the first place is because I'm a big HTPC enthusiast, been doing it for a long time. I'm with Team Comfy Couch, and most things I've long since worked out in a manner that suits me. But now with 3D coming around, I'm concerned a lot with how to get 3D from PC games, without having to use half side-by-side (Crysis 2 for example provides this when you don't have 3D Vision enabled) or using the 3DTV Play software. The GTX 680 has the horsepower to provide good framerates, even in 3D, while still keeping power use and heat down.
 
Posted this earlier, but that 3 SLI GTX 680 goodness took over the last page. Anyways,

Does anyone know if an i5-760(not sandy bridge) will bottleneck a GTX 680?

Display port omission seems like it's solely for maximizing profits. That's the reason sets don't have it.

And contrary to some of the replies, you can do full 3D at 60fps with HDMI, you're just limited to 720P. That's a big *, but it is possible if you're willing to sacrifice the resolution.

Not really sure what you have against 3D Play. The other alternatives also charge money. So it's not like you'll say any money by boycotting 3D Play. You'll just be giving your money to someone else.

Bottle necks aren't a hard-and-fast rule. It's not like you'll be limited to a specific framerate. That being said, the bottlenecks at 1080p are almost always at GPUs. You will see an increase in performance switching to it, but how much of an increase is entirely game dependent.

I'm not saving any money, as I've already bought it. =) But, as you've noticed, I have something against it, and that's because it reminds me of PureVideo, that also cost about $40-50 at the time, and now isn't needed. This should be a part of the driver IMO, just like PureVideo should have (seeing as I already paid for an MPEG-2 decoder because I bought PowerDVD). I just feel like I'm being nickel and dimed out of something that should just work, HDMI limitations notwithstanding.

Don't know what PureVideo is.

Look, I agree that it sucks. 3D is a selling point for Nividia cards. And it's one of the reason Nvidia gets away with charging more for their cards to begin with (part of the better support that generally exists).

But... what's the alternative? Going AMD's route and off-loading all the work to third-parties who charge just as much for their software as Nvidia does? If those are the options and Nvidia refuses to make everyone subsidize the 3D work that's needed for drivers, then I'd much prefer their approach to AMDs.

Sorry about that. I was able to score 2 of the 680's off of eVGA's site and 2-3 other people posted on the eVGA forums that they got one each. I did spam the site and used last Fridays email notification for time reference. So basically around 2:30pm (PST) I started to sit on the site and would refresh every 5 min or so and within the hour it popped up. My email last friday from the saying they are available was sent at 3:15pm and so I figured that is when they might put more up today and it worked.

I should have my cards in Wednesday evening since UPS delviers around 5-6pm here. I was hoping they would ship out today being that I have Wednesday off and that would give me all day to test and play with them.

Oh and Guru3d posted an Overclocking guide for the 680's and yeah, they clock up very nice and they got around a 20% improvement overall.

Lastly, if anyone is interested in the next few days I will be selling 2 580 GTX 3GB Classified eVGA cards. They are in great working condition and if you have not heard, eVGA is changing the Warranty and they are going to a plan that covers the card, not the owner. So anyone buying my cards will get the lifetime warranty that comes with them. PM if interested.
 
Was so close to upgrading my mobo and grabbing another 2.5 GB GTX 570 today (especially cause i get em dirt cheap) and doing SLI... but for the same cost I can sell my GTX 570 and buy a 680. GTX 570 SLI would be faster but I'm anti-SLI/Xfire so it wouldn't suit me. :/
 
I want this card but I just got a 570 6 months ago. The 570 should last me a few years, so I probably won't upgrade until the 700 or 800 line of cards is out.
 
I currently have a 5850, and am looking to start upgrading. I'd like to go nvidia again, so my question is, at this point, would my CPU be my bottleneck? Its a quad AMD 2.5Ghz with 8GB of DDR2.

Yes, it will. I have a Core 2 Quad Q9550 @2,8GHz and half of games I tried on GTX 680 in 1920x1200 seems to hit the CPU limit pretty often.

My computer has an AMD Phenom X4 955 CPU and a ATI Radeon HD 4890 and I'm thinking of upgrading the video card.

Should I do it or am I better off upgrading the CPU (but I'm not sure how to do that since I couldn't afford a new motherboard + a Core i7)?

I too have a GTX570. I'm currently debating whether to purchase another 570 and SLI, or just get a GTX680 or future 670.

You can always upgrade your videocard first and your CPU later.

If you are at 1080P or below your 570 should be fine. My 470 is still holding up well at 1080P. If you are going above 1080P then perhaps you might need a 680, but I would wait in your case.
 
I plan on replacing my 5970 for a single 680 solely for the purpose of getting much improved 3d game support on my 720p optima projector.

Will the 680 be able to handle something like crysis 2 max details at 720p with 4xmsaa and 3D at 60fps?

*breathes out

Well I play games on my TV which is 1080p but I also play on my monitor which is 1920 x 1200. I don't expect that to impact the performance too much. I'll probably need to get a new CPU(I have a Phenom II X4 965 BE) before a GPU. I haven't had any problems with my CPU though and I can still overclock it to 4ghz if needed.
