The first "proper" Kepler news Fri 17th Feb?

Gk110 will be approximately faster than gk104 by 20% margin. They were suppose to release both of them at the same time but as ATI failed with their 7970, we costomers ate ag104 instead of 110. Basically, it is now up to us which one to pick. 680 will priced at 500$(being 20% faster then 7970)- a fair buy overall. Gk110 will be released only in 2013 Q1. I might grab 680 and sell it later, closer to the 700 series show.

I dont see what all the fuss is about or why 7970 owners are in angst.

From the benchmarks in BF3 it was about 3-4fps ahead anyways and considering both overclock i really would not upgrade from a 580 for this.

And only 2GB Vram? come on clearly this is 570 renamed like in the earlier post.


Where is the old GTX 785 with the 512bit ring bus? I suspect NV have a monster lurking somewhere ready to be unleashed once people catch on to what they are doing.

They are drip feeding us and i hate it!

GTX 570 renamed ? come right off it - thats ridiculous
 
Since we're going back through the thread, allow me to be self-indulgent for a second and analyse my own guesses from a few weeks ago, in the light of what we know now:

... comments in bold, below the original predictions.

* The top GK104 part will be called GTX680.
Seems no doubt at this stage


* It will come with an RRP of either $449 or $499, and the cheapest models will cost around £350-£375 in UK shops on release.
Seems I was a bit optimistic. The card will probably be $50 more than I was expecting


* The cut-down part will be called the GTX670, will come with a $399 pricetag, and will appear in UK shops for around £300-£325 on release.
Who knows... Looks like silicon is limited and we won't see cut-down parts for a while


* The transistor count of the GTX680 part will be around 3.9Bn, comprising 1536 shaders which will perform two FP-operation per base-clock (either via a single FP-op at hot-clocked frequencies, or two at base-clock)
I was a little too pessimistic here... seems the transistor count is closer to 3.5Bn


* Base clockspeed will be 750Mhz, increasing to 850Mhz during "dynamic overclocking" ('turbo mode')
It seems we actually have a 700Mhz to 1Ghz dynamic overclocking, so a somewhat higher top-end than I was expecting


* Floating point performance will be rated at "up to 2.6TF" (single precision), with Nvidia using the "turbo mode" as the basis for this calculation.
Likely to be a shade over 3.0TF in practice, at the 'dynamic overclocking' 1Ghz frequency.


* The power draw of the GTX 680 will be similar to that of the stock 7970, coming in at around 225W in most gaming benchmarks. It may draw slightly more power than the 7970 on average.
Not TOO far off, but it seems the 680 draws slightly LESS power than the 7970.


* Performance of the GTX680 will exceed that of the 7970 in *most* real-world benchmarks, by around 10% at 1920*1200. At 2560*1600 the two cards will be very similar in performance (the GTX680 suffering more from memory bandwidth, particularly in games with heavy post-processing effects).
Seems pretty much on the money...


* The GTX680 will NOT have the same overclocking headroom as the 7970, and will lose out to a 1150Mhz 7970 in most circumstances.
We need to wait and see on this one...


* The GTX680 die will be smaller than the 7970, coming in at around 325mm^2.
Again, not too far off, but a little too pessimistic. The true die size seems to be a shade under 300mm^2


* The card will use a two-slot vapour chamber cooling system, with a traditional "blower" type fan to vent hot exhaust gasses directly out of the case.
Yes...


* The card will natively support Nvidia surround, up to three screens.
Again, yes. It seems the card can also support a 4-screen setup (though it's not clear yet whether this is as a 'surround' config, or only as a regular multi-screen config)


* The GPGPU features will have been heavily stripped from the GPU, in contrast to the upcoming GK110. Geometric throughput (and so tessellation performance) may suffer, leading to only slightly better than GTX580 performance in tessellation-heavy benchmarks.
it certainly seems this way, although the geometry throughput has not suffered quite as much as I feared, resulting in reasonable tessellation performance

Okay, there we have it. Overall I wasn't a million miles away, but I was more often than not a little pessimistic in my assumptions. GK104 has performed slightly better than I expected in almost all areas - with the notable exception of price! The card is $50 more than I expected it to be.

PCI-E 3, after all these next gen cards are pci-e 3, do you think kepler wouldn't gain from this technology? if not then why pci-e 3????
Click to expand...

Just because something uses the next iteration of the PCI-E standard does not mean it needs or will infact benefit from the improved bandwidth.

Upgrading a current build JUST to get PCI-E 3.0 is stupid.

They won't call their mid-range card GTX680.

Love some of you getting riled up about being hard done by over nothing but speculation and rumour mill.

Amazing. Enjoy entitlement lewzas!

Why should NVidia provide detailed specs, or confirm or deny speculation before they launch a new product? Why should they give the competition advance warning, and time to prepare counter measures?

AMD and NVidia behave in exactly the same way with their NDA's and threats of cutting supply chains to partners who do not tow the line. AMD only moved forward the 7800 paper release because real specs had been leaked. What NVidia has kept secret will take AMD probably 4-6 weeks to respond to once the info is available. Same applies on both sides.

Not sure about the base clockspeed but pretty sure it was original intended to spin up to 850MHz when it was aimed at the top mid-range part before they realised that it wasn't hugely far behind the 7970.

Because when you are about to charge £400+ for something and have been waiting for it due to delays (which are Nvidia's fault) then you deserve better.

Trying to stop people from buying a product that already exists and is already faster than any Nvidia effort deserves more than a ****in static bag with a poorly printed piece of card on (the black isn't even black).

HKEPC measured the GK104 as being around 319MM2 in size.
