GeForce GTX 680 Conclusion

First Look: GeForce GTX 680

From a distance, the NVIDIA GeForce GTX 680 looks a lot like the video cards of previous generations. Unless you're close enough to notice the details, the flagship models appear to all be about the same overall size. The outer dimensions for the GeForce GTX 680 give this 1.5" tall double-bay, 3.9" wide, 10.0" long graphics card a similar profile, but it's actually slightly shorter than the NVIDIA GeForce GTX 570, GeForce GTX 580, AMD Radeon HD 6970, and Radeon HD 7970 (each 10.5" long).

A rear mounted 60mm (2.4") blower motor fan with a slight offset takes advantage of the chamfered depression to draw cool air into the angled fan shroud, allowing more air to reach the intake whenever two or more video cards are combined in close-proximity SLI configurations. NVIDIA's add-in card partners with engineering resources may incorporate their own cooling solution into the GTX 680, but most brands are likely to adopt the cool-running reference design.

Specified at 195W Thermal Design Power output, the GeForce GTX 680 operates at levels less than the previous four generations of GTX flagship products. Because TDP demands have been reduced, NVIDIA's GeForce GTX 680 has also reduced power supply requirements. Rather than using the traditional eight- and six-pin PCI-E power connections, GeForce GTX 680 requires two six-pin PCI-E connections - identical to the GeForce GTX 570. Similar to previous GeForce shroud designs, the GeForce GTX 680 shares an identical vent near the header panel.

The GTX 680 reference design offers two simultaneously functional dual-link DVI (DL-DVI) connections, a full-size HDMI 1.4a output, and a DisplayPort 1.2 connection. Add-in partners may elect to remove or possibly further extend any of these video interfaces, but most will likely retain the original engineering. Only one of these video cards is necessary to drive triple-display NVIDIA 3D-Vision Surround functionality, when using both DL-DVI and either the HDMI or DP connection for third output. All of these video interfaces consume exhaust-vent real estate, but this has very little impact on cooling because the 28nm Kepler GPU generates less heat than past GeForce processors, and also because NVIDIA intentionally positions the heatsink far enough from these vents to equalize exhaust pressure.

As with past-generation GeForce GTX series graphics cards, the GTX 680 is capable of two and three card SLI configurations. Because GeForce GTX 680 is PCI-Express 3.0 compliant device, the added bandwidth could potentially come into demand as future games and applications make use of these resources. Most games work well using moderate settings on a single GeForce GTX 680 graphics card, but multi-card SLI configurations are perfect for gamers wanting to experience high-performance video games played at their highest quality settings with all the bells and whistles enabled.

I hope all of you buying these high end GPUs put them to good use when your not gaming! Folding@home or another distributed computing project, do your part to help science!
Peace out

Based on what factual evidence? I notice the 7970 couldn't even run a DirectX 11 tessellation test, so how will it compete with GPGPU tests?

# Is there going to be a difference?Christopher Fields 2012-03-22 08:04
I have 2 GTX 580's in SLI and they are water cooled. After months of rumors you guys have seemed to clear things up. I read things like "3 Times more powerful than a GTX 580 OC" to "The Card will be 8-9" Long".

I guess my question is this. My monitor is a 60Hz LED 32" 1920x1080 with a 5ms refresh rate. I play Battlefield 3 100% of the time. If I buy this card will my experience be any different?

I can prob answer this one myself.........no. Nvidia makes great products and the nice thing is when you buy a top end card you can usually skip a generation and wait for the next knock out contender. I would say if you have a GTX480 Series to upgrade. But if you have a Single GTX580 then put on the brakes and wait for the next show.

This of course is just my opinion. This is a great article, I always like reading your stuff Olin. Thanks for the time & effort you guys put into these reviews.

As a BF3 player myself (Das Capitolin), I can say that you're not going to SEE a significant difference between an overclocked GTX 580 and the new GTX 680. That being said, Active vSync is something worth considering, as are the extremely low sound levels and heat output. Since you've already purchased the 580's, I see no solid reason to upgrade. But if someone's deciding between the two, the GTX 680 easily wins my vote.

# Very good POWReSeRe 2012-03-22 12:35
i'm talking about skiping 1 generation GPU (and usually CPU too). Yes that's my philosophy either.
now i'm BF3in' w/ 460 1Gb SLI on an (pretty old but excellent LCD) EIZO 1600/1200. high settings (not ultra). Actually i could go ultra BUT with a drastic tweak down AA and other 1, maybe 2 settings.
In BF3 my nick: mantuitoru.

Once again, good review.
Long live the competition, anyway. in this case nVidia vs AMD.

Good card and excellent review! I love the low power usage and the new tech(txaa,adaptive v-sync,28nm,gpu boost,etc). A little concerned by the 256mb memory bus.
I wanna upgrade but until Nvidia (must have Phys-x) releases a single gpu card that can run Metro 2033 at max settings (4xAA,16xAF,very high quality,advanced DOF on and phys-x on) and average 60fps at 1920x1200 I guess I am stuck with my GTX480 sli for a long while.

at 3x the cuda cores than the card that was supposed to replace the 560ti that was supposed to be released first the benchmarks do not even seem to reflect the numbers of that affordable version? :(

Rumors however that this is the card was supposed to replace the 560ti but the performance was so good that they just gave it the 680 designation is very unsettling...

So...
What happened to the consumer friendly mid powered card that was supposed to be released first?

What the heck happened to the Kepler super powered card?

Better than 480 to 580 but is this just another incremental release or hardware without drivers?

Or worse yet...
Did we just get version screwed?

I don't recall NVIDIA ever making a statement on Kepler, it's roadmap, or what it was intended to replace. In other words, consider the source.

Maybe the rumors of gtx 780 were true?
If this is the replacement for the gtx 560ti..
and the gtx780 is coming out at the end of this year...
Then that would be fine with me!
If the following gtx 780 benchmarks are real:

wccftech.com/leaked-nvidia-generation-performance-slide-pits-upcoming-flagship-gk100-kepler-based-geforce-gtx-780-gtx-580/

Like I said in next gen console/xbox 720 article:
Anything without the benefit of present day maxwell development is sure to lead to a another very console limiting 10 year cycle!

# This..luay 2012-03-23 10:26
AMD replaced their mid-end product names with the higher end when they released their 6000 series, so not a first or even second time it has been done. This is a 560ti replacement and it will be marketed to death as a high-end product now and mid-end after July with a price reduction when the 580 replacement comes around.
If this card sells well, console makers should take note and try to cut a deal with Nvidia instead of AMD. I think this is why MS and Sony were not publicizing any future commitments of delivering next-gen consoles..

NVIDIA GeForce GTX 680 Reference Design

Load: 243 W

WOW?!

Also consider, extrapolating from your price comparison of other nVidia top end offerings, the GTX295 also came in at 500+ USD. That's pretty incredible.

# awesomecube 2012-03-22 19:50
If i buy this card, it means i will have to buy a new motherboard, LG2011 which means ill have to buy a new CPU and of course, the newest RAM. so all in all, the only thing i get to keep is my SSD and HDD. At the same time, i will also get a bran new case. so... the games i currently play and will play in the future dont require this much power.

this is what happens when devs dumb down the #ing games for consoles. people like me that used to upgrade every other cycle are now holding off and keeping their system alot longer. Means less PC part sales. =/ hope # will get better for us.

You don't have to buy an LGA2011 motherboard to use this card...it will work fine in any PCI-E x16 slot in older motherboards.

Just like PCI-E 2.0 is backward compatible with PCI-E 16x, PCI-E 3.0 is backwards to 2.0 and 16x as well.

That's a long way off in the future. Current games don't come anywhere near to saturating a PCI-E 2.0 x16 slot.

I like to emphasize the only factor keeping any hardware pipe from melting away from saturation is compromise and economics. The artist and imagination exists today for any game that is possible with tech at the end of the 21rst century. Creativity is both cpu and gpu limited!

The game that is possible in your lifetime is only limited by the rate of hardware acceptance. ( keep buying till cinematic levels of hyper real realtime rendering is possible... after that wait until holograms become a reasonable reality? )

# Bought 2: Selling Bothkzinti1 2012-03-27 23:02
I realized that this is merely a replacement for mid-range cards.
Even though it beats the best of the 5xx series, it's still only a mid-range card.
The REAL high performers will be out in a couple of months.
Nvidia's hype-machine got me once again.
I should know better by now.

I have one of these on order. Had 2 GTX 480 in SLi. This one card should easily beat them. My GTX 480 ran under water @ 900/1800/1848. They would out bench a stock 580 as they were the same GPU. Just tweaked a little.

This is a whole NEW GPU. Like Fermi was. The 670 has already been annouced and waterblock manufactors are shipping the bocks. Expect theor next release to be a lower version. Also Laptops are shipping with mobile versions. Check nVidia's homepage.

The next release will be the 780. Time range anything from 6 - 12 months. AMD could influence this.

I have my waterblock on order. I will also be SLi'ing them from about 2 months in.

NVIDIA?s newest flagship card(680) is superior to the HD 7970 in almost every way. Whether it is performance, power consumption, noise, features, price or launch day availability, it currently owns the road and won?t be looking over its shoulder for some time to come.

# RE: RE: NVIDIA GeForce GTX 680 Graphics PerformanceDavid Ramsey 2012-11-11 09:38
Hm, no, not necessarily. The 7970 is superior in some games (as these benchmarks show), and NVIDIA still can't match the 7970's lower power usage, especially in multi-card setups where Radeons not being used are all but disabled-- sub 5-W power consumption, fan stopped, etc.-- when they're not needed (i.e. if you're not playing a game.)

Still, I'd agree GTX680 performance is better overall, and they still own the world in GPGPU.
