[Vrzone] GTX 680 SLI Preview - Page 28

post #271 of 290
Too bad the 680 gets owned by the GPGPU power of the 7970. GPGPU matters to MANY people since the advent of bitcoin. People are now buying tons of 7970s instead of 6990s for their efficiency and similar hashing power.

Besides, the 7970s can OC like a maniac. These stock clocked 7970 vs 680 reviews are nonsense when ANY 7970 will do 200 more mhz on stock voltage. Wonder if we can say the same for the 680? Rumors don't mean anything. Sure SOME cards might OC a little, but that doesn't give an accurate representation of the percentage of high overclocks.

Time will tell, but you Nvidia fanboys haven't won entirely. The 7970 still smokes the 680 in certain areas, and still beats the 680 in AA scenarios.

Doesn't this imply the upper limit for automatic/dynamic clocking (hot clocking) on the 680's cores would be 1411 MHz?

"NVIDIA GeForce GTX 680 up to 4GB GDDR5
By Hilbert Hagedoorn, March 10, 2012 - 10:42 PM N/A


Many reports on the web indicate that NVIDIA's GK104 will launch later this month as the GeForce GTX 680. The card reportedly offers 1536 CUDA cores and a 256-bit memory controller, the standard models will get 2GB GDDR5 memory but there will also be a variant with 4GB GDDR5.

For the first time since the introduction of GDDR5, NVIDIA's GPU will be able to drive GDDR5 memory higher than AMD, which created the memory standard.

Dynamic Clock Adjustment is very similar to former “hot clocks”, with the difference that GK104 comes with several dozen power planes, and will operate on varying clocks depending on the computational load, card temperature and the power consumption. As we posted several days ago, the complete GK104 chip will operate at a lower clock, very similar figure to GTX 480: low power mode is 300 MHz, standard is 705 MHz extendable to 950 MHz – while the cores alone will be able to reach 1411 MHz when the chip is loaded to 100%.

If this is accurate on how dynamic over clocking will work and 1411 MHz is a loaded chip then it will be very formidable.

Wonder what a 24 / 7 over clock could bring at stock volts and over volted? Going to be interesting to see how this new tech pans out for GPU's.

If it could run 1411 24/7 then I think they wouldn't have devised this turbo boost. On the other if it was able to run that mhz, shaking head... that's the sound of the fat lady right there. We'll find out soon enough I guess.

I know what you mean. Im scratching my head thinking about how this is going to work with turbo boost behind the scene.

If I overclock is turbo boost going to take it even higher and make my system unstable and crash? Is there a dynamic over clock limit preset to keep this from happening? Does this take manual over clocking out of our hands and if so is there a way to disable dynamic over clock?

I started a thread with these questions and it boils down to 'we'll find out when the cards are in our hands'.

I'd guess that you could disable it and oc like normal.

Now that is interesting.... That's the first time i've heard about 3-way setups having less microstuttering.
Maybe because rather than frame-frame-pause-frame-frame-pause it's frame-frame-frame-pause-frame-frame-frame-pause so the pauses are short enough to not be noticeable?

What the hell happened to the post I made in here earlier today? It seems to have disappeared?

Anyway, going by the tom's hardware benchmarks (if real), I can honestly say I am not blown away, not that I expected to be. It's exactly where I thought the 680 would land in terms of performance. Generally 10 - 15% faster than the 7970 in most of today's current games, sometimes less depending on the title. Real world performance numbers in games I play (bf3, crysis 2, etc.) seem to indicate that the 7970 is on par with the 680, which is all that really matters to me. 3dmark scores, and all that other stuff, means nothing to me.

I am running 2x 7970's overclocked to 1125/1575 on stock voltage and they totally demolish any game out there. Cross-fired 7970's destroy any single GPU, including the 680, as well as last gen dual GPU solutions, so I see no need to ditch them and opt for 680's which only offer a handful more fps.

Pretty sure they got deleted. I was browsing the THG thread, went to go to the next page and it was gone. Clicked on it from the front page to. NV must be coming down hard an any and everyone.

Sure seems like it. Wow, that's pretty sketchy if true.
