ASUS has finally released its custom designed GTX 780 Ti graphics card and today we have a chance to check out the ASUS GTX 780 Ti DirectCU II OC version, which features the new version of the DirectCU II cooling, factory overclock as well as a custom design with a VRM part which is much better than the one on the reference graphics card. In a couple of next pages, we will try to check out if the new ASUS custom designed graphics card justifies the change from the reference design and has what it takes to cope with similar designs from competition
ASUS has finally launched a custom version based on Nvidia's GTX 780 Ti design and although a bit late to the party, the new ASUS GTX 780 Ti DirectCU II OC graphics card features a custom design PCB with much better and beefed up VRM, DirectCU II cooler and a decent factory overclock. The new GTX 780 Ti DirectCU II OC shares a lot of similarities with the ASUS GTX 780 DirectCU II series and in our book, that is definitely a good thing as why change something that is already good.
As you can see from the GPU-Z screenshot below, ASUS decided to use an average factory-overclock on the new GTX 780 Ti DirectCU II OC. While the standard reference GTX 780 Ti GPU is set to work at 875MHz for the base GPU and 928MHz for the GPU Boost clock, the new ASUS GTX 780 Ti DirectCU II OC works at 954 MHz for the base clock and 1'020 MHz for the Boost GPU clock.
Unfortunately, no factory overclocking was done on the 3GB of GDDR5 memory that remains at recommended 1'750 MHz (7'000 MHz effective).
While the typical Boost clock is set at 1'020 MHz, the maximum Boost of 1'097 (1.200v) MHz was achieved quite easily and the GTX 780 Ti DirectCU II OC held that clock most of the load time due to good custom cooler as well as good TDP target (Nvidia's Boost technology being based on both temperature and power on this card, the latter being predominant). The GPU Max. Boost clock only dropped in Furmark down to 954 MHz at 1.000v because of the power target and even lower past 80°C. It also did not held in some games where it dropped from 1'097 to 1'084, but that is not a big issue considering it actually stayed well above the advertised typical Boost clock.
