NVIDIA GeForce GTX 780 Review

7 thumbs up

The new NVIDIA GeForce GTX 780’s design language is similar to the company’s current flagship, single-GPU powered card, the GeForce GTX Titan, which should come as no surprise considering the cards are built around the same GPU.

As was listed in the specifications on the previous page, the GeForce GTX 780 is outfitted with a GK110 GPU, with a base clock of 863MHz and a Boost click of 900MHz. Unlike the GK110 on the Titan, however, two SMs (Streaming Multiprocessors) are disabled on the GTX 780, which brings the card’s CUDA core count down to 2304, from Titan’s 2688. The number of active texture units also decreases from 224 on Titan to 192 on the GeForce GTX 780.

The GeForce GTX 780’s 3GB frame buffer—half the size of Titan’s 6GB--is clocked at 6008MHz (effective GDDR5 data rate) and the memory links to the GPU via a wide 384-bit interface. At those clocks, the GeForce GTX 780 offers up a peak textured fillrate of 165.7 GTexels/s and 288.4 GB/s of memory bandwidth, which should place the GeForce GTX 780 among the fastest single-GPU powered graphics cards available today.

Like the GeForce GTX Titan, the GeForce GTX 780 is outfitted with a frame made of aluminum to add rigidity. And the card has a metal fan housing as well. The GeForce GTX logo along the top edge of the card lights up like the Titan’s too, and the brightness can be controlled via software as well.

The actual cooling hardware on the GTX 780 consists of a large vapor chamber with a densely packed, nickel-plated aluminum finstack, and large rear-mounted barrel-type fan with user-adjustable fan curves. Like the GeForce GTX Titan, the GTX 780 also uses low-profile components on about the front 65% of the PCB around the GPU, and the card’s cooler has a flat, ducted baseplate for unobstructed airflow, which minimizes turbulence and helps quiet down and better cool the card.

There is a window cut into the fan shroud that shows off the finstack (under a sheet of Lexan), and due to the fan configuration, virtually all of the heat produced by the card is exhausted from a system. Cards with centrally mounted axial-type fans, expel some of the heated air from the system, but dump the rest back into the case.

As evidenced by the pair of SLI edge connectors at the top of the card, the GeForce GTX 780 supports up to 3-Way SLI, and because the TDP of the card is only 250 watts, single 8-pin and 6-pin supplemental PCI Express power feeds are all that are required to power the GTX 780.

Outputs consist of a pair of dual-link DVI outputs, a full-sized DisplayPort output, and an HDMI connector. The GeForce GTX 780 should have more than enough muscle to push multiple displays simultaneously, and as such, it supports NVIDIA's 3D Vision Surround technology as well.

The 780 looks to be a pretty impressive card from all I've seen about it so far. However, it seems that the video card market is building cards that are extremely impressive, but increasingly expensive and out of the price range of a lot of gamers. Sure, they also released the 660 TI recently as well, but I think this push for $650-$1000 cards is going beyond excessive. I'd rather see them work on producing 670's and 680's at a lower cost so they could offer those cards at a reduced price and increase market saturation.

Yeah, I'm not sure what's up with Nvidia. Seems they've been bit by Apple's glamour-tech bug. Or perhaps they are trying to boost console sales?

Seriously, we don't need more high-end cards, just fairer prices on the cheap ones. And there's no need for all the metal on these things, it just raises the cost for Nvidia and consumer. It gives very little if any value. Tech will become outdated, why bling it up?

Don't get me wrong, I love Nvidia's products. I just don't think they are headed down the right path with this.

Personally, I think they might be feeling a little bored because AMD's tech isn't keeping up. However, if they put this new tech against AMD's at the previous price-point, it would put AMD out of business, which wouldn't be good for anyone. So they decided to make them more expensive, since they have the room to work with...

This is their "high end" level of cards, the 680 when it first came out was 600+ dollars and now you can get one for 450, the opening price for something new is always higher. Assuming the scaling is the same, the 760 ti will be around 350-450 dollars and will outperform a 670. The price to performance ratio stays roughly the same, just more performance is more expensive

Heck of a nice card. It would be hard to let this card go after testing,.....

Hi I just bought a titan after testing a 7970 for my purposes. No i am not made of money - but i am quite keen to do certain things. One of which is gaming in stereoscopic 3d. Nvidia is the only option here. Another is to do GPGPU CUDA in double precision. Nvidia sucks at this unless you pay the big bucks for the dedicated GPU cards or buy a Titan. AMD with OpenCl is much more cost effective. MUCH. Both stink for producing stereoscopic 3d via say quadbuffered OpenGL. The Nvidia kit can actually do this but Nvidia actively prevents you from doing so because they want to force you to buy the high end quadras... In a nutshell - I want to play my FPS shooters in stereoscopic 3d, AND I want good CUDA/OpenCL double precision compute performance AND I want to be able to write my own stereoscopic 3d code (even script it say from mathematica) Nvidia is the closest to this, and their hardware can easily support it, yet they choose to nobble their drivers and such to force me to buy vastly more expensive hardware that may not do what I want anyway. Waugh! So frustrating! And to boil it right down - what can a GTX780 do? what is its DP floating point performance in CUDA? Can I do my own stereoscopic 3d code?

please help - I could find this out for myself (because nobody seems to be doing this or asking about it - or at least google is not my frend on this - wonder why?) but it is EXPENSIVE...

cheers

You could flash your card's BIOS to Quadra specs. Try google again, methods exist to do this already, but you could screw it up if you make a mistake.

There's no rule that companies have to build their top end products at low enough cost for the majority of consumers. People always complain about the cost of high end / top of the line hardware. I'm not a rich guy at all so I get it to a limited extent. But at the same time, if you can't afford it / it's too pricey for you then get a lower end card. New mid range cards are still going to offer way better performance then previous gen in most cases. I'm sure there will be good performing 700 cards for less money, so everyone can stop crying about top end being so expensive, geez.
