Yeah that demo looks nice, cant wait to try it out

Yeah, if it were ~ 320-350€ i might consider it too, but not for ~490-499€ (that's what over 640$ lol

I checked techpowerup review as the last one and i had a hunch its gonna be like that. Its only 16% faster then 580 GTX, Ok it can be little more here and there.. But that made me think for a bit, exactly that's nothing special for next-gen "high-end", same goes for AMD 79x0..
I payed 320€ for mine, ok 250€ -tax (got a good deal) and now to pay 2x more just to have ~15-20% better perf. VS this 570 at 900mhz OC? -_- Im at lower non HD reso anyway..

The only thing that made me itch was BF3, but imo that's to be expected. They knew its top sheit and made some tweaks especially for that (Fillrate, FP16 +aa) lol no doubt about that.
But then to have lousy openCL perf. in other stuff and overall "similar cuda mix" like GF114 is a bit lame tradeoff. Yeah they had to make that approach to eliminate no hotclock freq.. but only 8 polymorph 2.0 tessellation engines? at least the same 16 would be nice, esp. for that "high-end" price.






Anyway this looks cool, but its not available in directX API yet..

Prior to Kepler, for the GPU to reference a texture, it had to be assigned a “slot” in a fixed-size binding table. The number of slots in that table ultimately limits how many unique textures a shader can read from at run time. Ultimately, a shader was limited to access of just 128 simultaneous textures in Fermi (which aligned with the API limits of DX11).

With bindless textures in Kepler, this additional step isn’t necessary: the shader can reference textures directly in memory, making binding tables obsolete. This effectively eliminates any limits on the number of unique textures that can be used to render a scene: over 1 million unique textures are possible.
Besides dramatically increasing the number of available textures, another added benefit of bindless textures is reduced CPU utilization:

At this time, bindless textures is only exposed in OpenGL. But in the future it’s possible this could be exposed in DirectX via NVAPI, or future versions of DirectX.

I'm not gonna buy a $500 card anytime soon, but do so many people really care about heat and noise? Usually when my card gets noisy it's because I'm gaming and I'm generally using headphones or decently loud speakers then. Heat doesn't matter to me as long as it works.

Eh, just something I notice in all reviews, they tend to give as much weight to heat+noise as performance.

Instead the capabilities of the Polymorph Engine itself have been doubled, making each Polymorph Engine 2.0 twice as powerful as a GF114 Polymorph Engine. In absolute terms, this means each Polymorph Engine can now spit out a polygon in 2 cycles, versus 4 cycles on GF114, for a total of 4 polygons/clock across GK104.

Throughput is doubled!

However as slawter said. i cant help but feel that this release is mid range with added features to surpass that of the competition. Im not sure if thats because the rumoured GK110 i have read about isnt far off or because of the restrictive 2GB of mem and 256 bit mem bus in high resolution surround gaming if i do decide to go multi monitor. Bottom line is the performance increase in all games from my GTX285 to GTX680 would be A LOT and i would gain DX11 but am i going to regret getting one if gk100 comes out around 3/4 and is 15-25% faster ?

You can bet we will see GK104 a few months after 8970 launch.

Has anyone tried RAGE yet? I wonder if this would help the texture loading.

Maybe they will promote it in that 680GTX tech demo, NV likes openGL tech demos

Yeah i know, i've read that review for tech spec., Anandtech always owns at that

but you seem to overlook one part

at least the same 16 would be nice, esp. for that "high-end" price.

Well imo it doesnt matter if it has double the throughput, it basically equals "16-18" in 580gtx.. And that's nothing special, not for that price ;p

Idc about power consumption, i want mooar powah in single gpu xD

Is this ALL they released? JUST the 680? I can't afford that, I was hoping for other cards to be released too. Looks like it's a 7870 or 7850 for me.

Any news on a 670?

680 SLI / Quad SLI

Seems SLI is not scaling that well in all games with Keplars....strange

i don't care anymore... going to get that GTX680

FOR MOTHERNVIDIA!

HAHAHAHa...well pare what can I say you must be rolling in it! Hehehe say ....u dont need that 7970 any more...send it to me, I will keep in safe! Promise!!!

Wow cheapest 680 now in HKG is US$512 for Colorful branded 680 GTX
