GTX 680 will feature 1536 SP and 256-bit memory. However, contrary to rumours, NVIDIA has retained the shader hotclock

GK104 significantly improves upon GF110/GF114's memory controller, setting a new record for reference memory clock at 6 GHz. This equates to a memory bandwidth of 192 GB/s - exactly the same as GTX 580 despite the narrower memory bus.

This is the second leak stating the same thing I've seen tonight, so I posted it :whiste:

Holy crap, if true this thing is going to be a monster performer.

"NVIDIA will reveal details about GTX 680 in an event on 12th March, with a hard launch rumoured for 23rd March"

LOLWUT?!
Triple shader count?!


If those specs are true, i think we can agree this will slay Tahiti.

Badly.

Even assuming minimal performance increase per core over fermi.


....please don't fuck up on price nvidia, please please please.
Compete with tahiti price wise, so your mid segment also gets something out of this :C

I think it would be pretty safe to say the performance per shader will be far less. There's no way to fit 15K+ Fermi shaders in <400mm^2

Wow there is a lot of information in this article. I wonder if they can be confident about everything said in there. Launch dates, if they are genuine, is a very good news for everybody, really!

Also, they refer to the stacked pci-e connector as experimental and possibly scrapped, which again sounds like they have true information about this. I don't believe they'd throw that blindly if they really didn't know anything!

Can't wait! :awe:

What do you guys think about the naming scheme then? I'd say depending on how it performs, they might have pushed back GK110 to the next generation, or cancelled it altogether. If GTX680 performs well enough vs. the 7970 (which would probably imply that it beats it), that sound reasonable.

I'm taking those specs, and the product name GTX 680 as GK104, with a grain of salt.

That things look like it could cost $600-$900.

A new node.. maybe they're redesigned?


@nenforcer:

Yea i'm kinda worried NVidia will play the AMD game.

Those specs look like a even more clearer performance king of this generation than 580 was, except we don't have a nice 6970 performance/price this generation.

700-800 USD gpu :C

Wouldn't these verify the claim that the SPs are weaker than they were before?

This is a leak from before...

It shows by my count, 1536 shader cores.

They could prolly cram 1024 Fermi cores onto a die that big at 28nm.. so having 1535 cores would suggest a big change in architecture.

It would be hilarious if they went with VLIW.

I'm guessing that Kepler cores can do only one op per clock instead of ~2 that Fermi did. Should have slightly higher theoretical performance than the GTX 580, I'm more interested in what TDP this part has and what improvements have they've made in the arch though.

I dunno if it will destroy Tahiti, it'll defeat Tahiti stock clock to stock clock but it's shaders run only run 1400 Mhz and its core clock is only 705 Mhz, it's an impressive piece of hardware but remember that the 7970 can overclock up to 1200Mhz on the stock cooler and it has 2048 shaders which is overall faster than 1400 with 1536. My prediction, it will be 15% faster in stock form to the Tahiti cards, the 256-bit memory bus though may hold it back though.

BTW, I tend to go with Nvidia in my video card selections typically but I think its going to consume a lot more power then the ATi cards and overclocking the 7970's will even up things.

AMD shaders aren't the same as Nvidias.

We can't make comparisons like that yet.

Also these rumored specs match up with some others that included 128 TMU's and 32 ROPs... Sound familiar?

What are the ROP's and the Texture units on the thing? Shaders are great but pixel rate plays a big part in Frames per second.

Like I said, the specs are impressive but I think ATi matches up better then what people think. The real winners will be the board manufacturers due to it being likely cheaper to produce than the GTX580 and 7970 series cards(2/3rds the amount of ram chips and a shorter board).

GK104 is the equivelent to the GTX 460/560ti, not the 470/480/580/580/560ti448 though.

This is Nvidia's 28nm mid ranged chip, or it was suppose to be.

Dammit, so when could I expect the GTX 670 Ti? Oh well, 6 more days for some solid info!

I'm game. Bring the competition (and not price fixing.) I'm in the mood to buy :D

Would be incredibly impressive if NV fixed their memory controller so completely they managed to get 50% higher memory clocks.
Not impossible, since AMD are managing 5.5GHz, but to go from 4GHz to 6GHz is a massive jump. Not unachievable, but impressive if they did manage it.

At this point, we really can't pronounce ourselves on that, though. Early on it made sense that it would be second to GK110, but we have no idea what's up with that. Also, if this is GTX680 and mid range, how is GK110 named, then?

To me, if they're using the GTX 680 name for GK104, it feels a lot like they just pushed back GK110 to the GTX7xx series, which would make sense, especially if GK104 can hold its own vs. AMD's offerings for now! :biggrin:
