Nvidia's GTX Titan is THE flagship graphics card to own right now, but at around £900 it is marketed at the ultra high end enthusiast audience. Moving down a single notch in the Nvidia hierarchy is the GTX780, a card made slightly more affordable, around the £550 mark. Today we look at the custom cooled, overclocked ASUS GTX780 Direct CU II OC to find out if this is the high end solution to own in the latter half of 2013.
ASUS are well known for creating high end, ultra expensive ‘over engineered' solutions targeting the rich enthusiast user. Their Republic Of Gamers motherboards deliver great overclocking performance and graphics solutions such as the ARES attract the attention of the global media.
The ASUS GTX780 Direct CU II OC is a proprietary design featuring the latest version of the Direct CU II cooler. ASUS are using flattened copper heatpipes to make direct contact with the GPU Core, which they claim reduces load temperatures by up to 20 percent. This card uses a 6 phase power implementation to reduce power noise by 30 percent and enhance power efficiency by 15 percent.
The ASUS GTX780 Direct CU II OC has received a core clock boost from 863mhz to 889mhz. The Boost speed is set at 941mhz and the memory speed 1,502mhz (6Gbps effective). The GK110 core is built on the 28 nm process and this card has 48 ROPS, 192 TMU's and 2304 CUDA cores. The 3GB of GDDR5 memory is connected via a 384 bit memory interface.
Love this card, but its still a bit rich for my blood. are they doing this with the GTX 770?
thats a crazy OC for such a high end board.
I love the nvidia boards in this generation, but they are all so expensive. im still looking at getting a 760 as I only game at 1080p. think its enough. waiting on the ti version if there is one coming out soon
Great review, but for under half the price I would recommend getting a GTX 760. I got one last week and it’s a great card for around the £210 mark.
Great review.
I wish you guys would actually find a truly STABLE overclock. Just like everyone else you get a clock speed that’s stable for a 10-minute benchmark, but not for real-world games. It’s misleading and people who buy and overclock the card are disappointed to find that truly stable clocks are much lower than those in reviews. I haven’t seen anyone across all GTX 780 threads get a truly stable core clock above 1040MHz, even for the water cooled custom ones. You should really run intensive games for 3-5 hours to get your overclocking results, and you’ll see they are nowhere near as good as you thought.
I played a few games on it for hours and it was stable at 1040mhz (no artifacting on memory or core and no hard locks etc). Its only misleading if people think that every graphics card in that particular range will hit those speeds, but they don’t as we mention in many reviews and I hope our audience know from 3 years of reviews here that every card can deliver VERY different results. Same as when you are overclocking processors.
We attempt to make everything as transparent as possible.
I bought one of these and the card is stable at 1204mhz with a 200mhz boost on the memory (couldnt get the memory overclock they achieved to become stable) but this clock speed was playable through the first half of crysis 3 (got tired of the game after a few hours) Then played borderlands 2 for a few more hourse. I finished off my testing with some fur-mark burn in tests to insure stability (2 hour burn in test). My room did get quite a bit warmer during this gaming period, but my window was open and outside was cold. The temps held steady at 73-76 Celsius for most of the duration of testing with the max temp being 77 degrees Celsius.
