Yeah, I'll have to look into that.

Once Swiftech comes out with their new blocks I'm ordering two of them so I can overclock.

Have you tried OCing on air ? they should do pretty good. I wont be adding aftermarket cooling...that's why I'm interested.

They'll OC on air just fine. Got mine to 1000 on the core without needing any voltage bump at all.

I just don't generally like OC'ng GPUs unless I'm on water. Guess I had too many of them die on me in the past and am squeemish about it (most of them were Nvidia, though.)

Finally the time has coming!

The thread title "No GTX680 until Q2 2012" is wrong.

Are you ready? :D

Nvidia will finally unveil GTX 680 and probably reviews next week on 12 March 2012 with hard launch on 23 March 2012.

GTX 680 will be 10 inch long, 705MHz core clock, 1536 stream processors, 1411MHz shader clock, 6GHz memory, 256bit memory bus and 192GB memory bandwidth. The experimental PCIe power stacked may not make it to final production cards.

I knew they had to be getting close now. All of our retailers down here have slashed the prices on all 5 series cards

Its not the 680, its the 670. Titles still right.

I to have heard that the first card released won't be high end. Has this been confirmed though

Kyle from [H] says it is 680,

and this,

Seeing some benchmarks show 7970 in the lead, mostly in tessellated situations there, other "normal" synthetic 3D benchmarks and gaming benchmarks show 680 faster. Driver advancements still happening as well for 680.

If it's actually $400 (with a die size below Tahiti and only 256-bit memory bus that seems quite possible) this will surely shake things up! That would mean 7970 coming down $150 and everything else following by around $100-50 or so.

He also said he wont switch from his 7970's... So it can't be that good.

Wow what a way to break NDA from someone who heads one of the largest hardware site.

Would you switch to a card that is slightly better at times and slightly worse at others? I doubt anyone would. If what he says about the 7970 being better at tessellation is true then that's where frame rates matter much more so in that regard the 7970 is probably still the better overall performer.

I'm not sure, but he isn't saying anything specific, just general statements. That sort of thing must be allowed. If not, he could be in trouble. ;)

If its $399 its not faster, if its faster it will be $599 or higher. Pretty much that simple.

It seems like he's just seen some benches and isn't actually benchmarking the card himself yet, or has one for that matter.

Yeah I'm not putting too much faith in the rumours. I've never seen NV undercut on price when releasing second really. Usually AMD prices were just overinflated due to over demand and once NV's cards hit demand is spread out more as well as yields being better so prices fall as a result.

For NV not to charge the same as AMD for a card that performs the same seems very unlikely, so if it does happen it will be pretty shocking.

The thing is, that NV really wanted to price this card at $300, but they overestimated the yields, so they had to bump the price a bit. It is a mainstream chip after all and the only reason to name it like a high-end is because of AMD.

Just imagine, if AMD jumped in performance like it usually happens over one generation. Then GK104 would be called GTX 660 and they would have to be priced around $300-350 anyway.

If some of the rumors I'm hearing about a GK110 launching only after a month from GK104, then it makes perfect sense.

According to a site that is not entirely accurately 28nm production at TSMC has been on hiatus for a few weeks now! eek!

Kepler has a new feature, it will have hardware overclocking technology called Speed Boost like Intel's Turbo Boost.

Here will be GTX 680 4GB cards as well as factory OC cards coming soon after 23 March hard launch. Nvidia will also launch dual GK104 card in May probably will be called GTX 690 and finally the ultra high end monster chip GK110 will launch in August that will have 2304 CUDA cores.

Last year Epic showed off Samaritan Tech Demo ran on 3 GTX 580 in SLi on a PC with massive PSU but this year they showed it off again running it with a single Kepler card... on a PC with a 200W PSU!!!. :eek:

12 March will be very interesting day to find out how the hell GTX 680 can surpassed 7970 in most games benchmarks that used smaller memory interface, less memory bandwidth, a single Kepler card faster than 3x GTX 580s in SLi and far more energy efficient on a PC with tiny PSUs.

They were using only FXAA instead of MSAA though.

Not to mention, that the engine probably went through some major optimizations too in the meantime.

Here very interesting info about GTX 680's Dynamic Clock Adjustment which is very similar to hotclock, the core clock will operating in 3 modes with 300MHz on low power mode, 705MHz on standard power mode and 950MHz on high power mode or maybe Speed Boost mode. :)

Lets wait till we have all the official info, but, i'm disappointed. A 256 bit bus ? :|

They've just renamed their mid end part because it performs well enough and the high end is late.

As for the Samaritan demo, clearly they are running it in different settings with further optimizations. Not sure about the 200w PSU part, Mark Rein is renown for getting the facts wrong in statements he makes. He actually said the last time they ran the demo that it was on 3 Geforce ti500's :lol: My guess is that he meant the video card is using 200w or something like that, where as 3 x 580 SLI would be like 700w.

Hmmm I think I will give it a day or two if Mark Rein or his secretary noticed the errors in statements then they will sent emails to editors to correct the errors in statements.

I noticed many 3 way GTX 580 SLi reviews used 1500W PSUs, accorded to Nvidia website, a GTX 580 required a minimum 600W PSU and a GTX 580 card output power used 244W so a 3 GTX 580 cards in SLi used 1088W then it will need 1200W or 1500W PSU.

You will start to see benchmark leaks and such probably in the next couple of days. I think most of those will be at less than 2560 resolution. And let's face it, you don't need a flagship card for resolution that small. Honestly, like always, we are going to have to put it through [H] large resolution gaming paces before we make a call on where it is compared to 7970. I think the 680 will be faster but by how much, we don't know yet, and I have seen NO MSRPs confirmed.
