NVIDIA GeForce GTX 780 Review: The New High End
by Ryan Smith on May 23, 2013 9:00 AM ESTMeet The GeForce GTX 780
As we previously mentioned, the GTX 780 is very much a Titan Mini in a number of ways. This goes for not only the architecture, features, and performance, but as it turns out it will be the case for the design too. For the reference GTX 780 NVIDIA will be straight-up reusing the GTX Titan’s board design, from the PCB to the cooler, and everything in between.
As a result the reference GTX 780 inherits all of the great things about the GTX Titan’s design. We won’t go into significant detail here – please read our GTX Titan review for a full breakdown and analysis of Titan’s design – but in summary this means we’re looking at a very well built blower design almost entirely constructed out of metal. GTX 780 is a 10.5” long card composed of a cast aluminum housing, a nickel-tipped heatsink, an aluminum baseplate, and a vapor chamber providing heat transfer between the GPU and the heatsink. The end result is that the reference GTX 780 like Titan before it is an extremely quiet card despite the fact that it’s a 250W blower design, while it also maintains the solid feel and eye-catching design of GTX Titan.
Drilling down, the PCB is also a re-use from Titan. It’s the same GK110 GPU mounted on the same PCB with the same 6+2 phase power design. This is part of the reason that GTX 780 has the same TDP as GTX Titan, while at the same time giving GTX 780 as much or more TDP headroom than Titan itself. Using the same PCB also means that GTX 780 has the same 6pin + 8pin power requirement and the same display I/O configuration of 2x DL-DVI, 1x HDMI, 1x DisplayPort 1.2.
Also being carried over from Titan is GPU Boost 2.0, which was first introduced there and has since been added to additional products (many GeForce 700M products already have it). GPU Boost is essentially a further min-maxed turbo scheme that more closely takes into account temperatures and GPU leakage characteristics to determine what boost bins can be used while staying below TDP. It’s more temperature dependent than the original GPU Boost and as a result more variable, but in cooler situations it allows tapping into that thermal headroom to hit higher clockspeeds and greater performance, TDP allowing. At the same time this means GTX 780 also gains GPU Boost 2.0’s temperature target functionality, which allows users to cap boost by temperature as well as TDP. As with Titan this limit is 80C by default, with the idea being that adjusting the limit is a proxy for adjusting the performance of the card and the amount of noise it generates.

AMD released some significant driver updates in ~Oct 2012, branded "Never Settle" drivers that did boost GCN performance significantly, ~10-20% in some cases where they were clearly deficient relative to Nvidia parts. It was enough to make up the difference in a lot of cases or extend the lead to where the GE is generally faster than the 680.On the flipside, some of AMD's performance claims, particularly with CF have come under fire due to concerns about microstutter and frame latency, ie. the ongoing runtframe saga.

Drivers possibly?kallogan - Thursday, May 23, 2013 - link
High end overpriced gpu again ! Next !wumpus - Thursday, May 23, 2013 - link
Except that the 780 is nothing more than a Titan with even more cuda performance disabled. Presumably, they are expecting to get Titan sales to people interested in GPU computing, if only for geeklust/boasting.wumpus - Thursday, May 23, 2013 - link
My above comment was supposed to be a reply. Ignore/delete if possible.ifrit39 - Thursday, May 23, 2013 - link
Shadow Play is the most interesting news here. It costs a not-insignificant amount of money to buy a decent capture card that will record HD video. This is a great alternative as it requires no extra hardware and has little CPU/GPU overhead. Anything that ends up on the net will be compressed by youtube or other service anyway. I can't wait to remove fraps and install shadow play.ahamling27 - Saturday, May 25, 2013 - link
Fraps isn't the best, but they somehow have the market cornered. Look up Bandicam, I use it exclusively and I get great captures at a fraction the size. Plus they aren't cut up into 4 gig files. It has at least 15x more customization like putting watermarks in your capture or if you do like to segment your files you can have it do that at any size or time length you want. Plus you can record two sound sources at once, like your game and mic, or your game and whatever voice chat software you use.Anyway, I probably sound like I work for them now, but I can assure you I don't. This Shadow Play feature is definitely piquing my interest. If it's implemented wisely, it might just shut all the other software solutions down.

There were two things that instantly made me dislike this card, much as I've liked Nvidia in the past: completely disabling the compute performance down to 600 series levels which was the reason I was more forgiving towards AMD in the 600/7000 series generation, and that they've priced this card at $650. If I remember correctly, the 680 was priced at $500-550 at launch, and that itself was hard to stomach as it was and still is widely believed GK104 was meant to be their mid-range chip. This 780 is more like what I imagined the 680 having been and if it launched at that price point, I'd be more forgiving.As it is... I'm very much rooting for AMD. I hope with these new hires, of which Anandtech even has an article of their new dream team or some such, that AMD can become competitive. Hopefully the experience developers get with their kind-of-funky architecture with the new consoles, however underwhelming they are, brings software on the PC both better multithreaded programming and performance, and better programming and performance to take advantage of AMD's module scheme. Intel and Nvidia both need some competition so we can get this computer hardware industry a bit less stagnated and better for the consumer.

The 680 was $500 at launch, and was the main reason why AMD received so much flak for their 7970 pricing. At the time it launched, the 680 blew the 7970 away in terms of gaming performance, which was thee reason AMD had to respond with across the board price drops on the 7950/70, even though it took them a few months.
