To overclock the Nvidia GTX 780 Ti today we used the latest version of MSI Afterburner which is based on RivaTuner.
As we mentioned earlier in the review Nvidia have added a new power balancing feature which helps to get the most out of overclocking the hardware. The GPU gets power from three sources, the 6 pin and 8 pin connector and the PCI Express interface. When a user overclocks the hardware the power delivery can be unbalanced with power drawn from one source more than the others, potentially maxing out the clock speeds.
Nvidia say the new feature can direct power from one input to another, meaning that if you max out one power source then the algorithm will take more power from others to compensate. Time to test it out.
I don't think we have seen such incredible headroom from a high end core. Obviously all samples will vary slightly, but we managed a 28% overclock on the core before artifacting would occur. We weren't expecting a lot of headroom on the GDDR5 memory, especially at such high default speeds. We managed to increase this to 1,800mhz (7.2Gbps effective).
Even with the AMD R9 290X overclocked to 1,100mhz core, the GTX 780 Ti at 1,122mhz performs at a significantly higher level, scoring 17,522 points – a new record in our labs for a single GPU.
Absolutely mega – love it ! thanks!
Yeah this is awesome – well impressed myself, but the price is painful. Ah well – plenty of GTX780 non TI bargains right now for close to £400.
I can’t wait to see what MSI do with this one – Lightning FTW!
Ultimate setup? the Kitguru test rig with two GTX780 TI’s and that ASUS monitor. time to start saving. lol.
Best review of the Ti today, took me a long time to read it all. im ordering one today, just need to get the best deal !
They do make good reference coolers – ive read on forums that people say they suck, but I still have a reference GTX780 from ages ago and I had hardly hear it in my case. this is just mega, but ill have to pass until January. Christmas coming up, need to buy presents!
Well this came out of nowhere, I didnt know Nvidia were making so many changes to the shaders/TMUs etc. I think this has to be the limit of this generation of hardware, but its phenomenal. next year I think Nvidia will get Ultra HD 4k smooth at 60fps in most titles at high IQ. next gen.
Or two 780 Ti’s!
I think the R9 290 is the besdt value for money card right now by a long shot. But, and its a big but – I dont want the reference cooler.
I have posted on many forums, such as Sapphire’s asking for release dates of toxic editions etc, but no one is answering. GTX780 Ti is too much money, even though it is clearly the new leader. I want the R9 290 but without the shitty cooling system 🙁 a lot of people are waiting AMD so get your finger out.
Just ordered two for my new rig – great review and very honest.
