Today NVIDIA launch the GTX 780 graphics card and we have the ZOTAC branded version on our test bench. We'll be putting it through a selection of real world tests against overclocked 680 and 7970 cards to see how it does in titles like Crysis 3, Metro:Last Light and GRID 2.
Nvidia nous avait surpris et clairement émerveillé avec la sortie de la Titan, sorte de mono-GPU hors norme. Mais voilà, la carte flirte avec les 1000€ à l’achat et s’adresse donc à un public aisé. On attendait donc une version plus accessible de cette carte graphique, qui s’avérait être un dérivé du monde professionnel. On en rêvait, Nvidia l’a fait, voici donc la GTX 780, remplaçante de la vénérable GTX 680, avec un potentiel bien plus marqué.
Today Nvidia introduced the first card in its new 7 series of graphics cards, the GeForce GTX 780. Based on the name you probably expect an entirely new architecture, but the GTX 780 is based on the same GK110 GPU that's the foundation of the GeForce Titan. The new card has slightly fewer CUDA Cores (Nvidia's term for its unified shaders), somewhat less video memory and lower clock speeds.
Graphic cards
The GeForce GTX 780 is based on the 7.1 Billion transistor behemoth GK110 GPU used by the GTX TITAN. The GTX 780 delivers a massive 70% performance upgrade compared to the GTX 580, equipped with 2,304 CUDA cores and 3GB of memory across a 384-bit interface. The GeForce GTX 780 also inherits GPU Boost 2.0 from the GTX TITAN, providing superior clock speed boosts through smarter headroom assessment and optimized boost algorithm.

It almost feels like we have been seeing the 600 series of cards from Nvidia for a few years now. At a year and two months we are a little past due to see a new generation of cards and today we can finally take the wraps off of NVidia’s latest card, the GTX 780. Rumors have been going around for a while on this launch so let’s just jump right into it and see what it’s all about and then how it performs. One thing is for sure, this will be the start of a lot of exciting cards, and 2013 is going to be a good year!
Its that time of year again where NVIDIA have a new series of cards in the pipelines and as we have seen running up to today, the number of rumours and leaks that have been flying about are as profound as ever. For some this leads to pure confusion as to what is to be seen and what is complete rubbish, and for people like myself it leads to pure frustration as I know all the true facts and figures, meaning that when I see the rumours and false facts floating around I can do nothing but sit and wait until the NDA lifts to put a number of these claims to rest with the real specifications and performance figures behind the new cards.
So here we have it, the GTX 780 - the first in the new line of Kepler based 700 series cards and before we get too far into the nitty gritty of what's new in the 700 series, I want to make the following fact clear and true - the GTX 780 CANNOT be flashed in any way to effectively turn it into Titan. There are a number of reasons for this; first off, whilst both cards share the same GK110 core, the 780 has far less CUDA cores, is a different revision of the core chip and has less texture units on-board. On top of this, there is also half the amount of video memory and a number of components in the power region of the PCB are missing as the 780 does not require these as opposed to Titan.
Point out of the way, NVIDIA's new 700 series cards are here to replace the ever popular 600 series, although they are not a re-hash and re-brand of 6xx cards as some may presume. Whilst the GK110 cores may be featured on both 600 and 700 series cards, they will have subtle variances to them, mainly on the front of CUDA core count and texture filters and so forth.
So what is the 780 in relation to the 600 series cards. Whilst it may look like Titan, it is a slightly lower performing card. Titan is more geared towards users with multiple high resolution displays and thus the higher 6GB of GDDR5 memory that it encompasses. The 780 whilst still home to 3GB of GDDR5 is more aimed at users who are going to be gaming on a single screen at high resolutions with all the settings turned to 11. Over its predecessor, the GTX 680, the 780 has 50% more CUDA cores with a count of 2034, 50% more memory, up to 3GB from 2GB and overall a 34% increase in performance. Interestingly enough, GTX 580 users who upgrade to a 780 will see a whopping 70% gain in performance between the two cards and a 25-30% gain can also be found over AMD's 7970.
When Titan released in February, it seemed likely that NVIDIA’s GeForce 700 series would be held off on for some time. Well, with today’s launch of the company’s mini-Titan – ahem, GTX 780, we've been proven wrong. Compared to the GTX 680, it offers a lot of +50%’s – but is it worth its $649 price tag?
NVIDIA have just launched the GeForce GTX 780, here today Stuart Davidson brings you a video overview to accompany our full text review.
Am heutigen Donnerstag startet NVIDIA seine neue Grafikkarten-Serie mit der Vorstellung der GeForce GTX 780. Die GTX-700-Serie soll dabei nach und nach die bisherigen Modelle der GTX-600-Serie ablösen. Was es für Neuerungen gibt und wie sich die GTX 780 in der Praxis schlägt, dass verrät unser Testbericht.
