It’s 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.
