Inno3D GeForce GTX 780 Ti iChill HerculeZ X3 Ultra 3GB review: overclocked 780 Ti

It's as fast as the name is long, fortunately



Last week Nvidia introduced the GeForce GTX 780 Ti, a new flagship card in response to AMD's Radeon R9 290X. The GTX 780 Ti is based on the same GK110 GPU as the existing GeForce GTX 780 and GeForce GTX Titan, but due to the higher number of Cuda Cores and faster clock frequencies the Ti version is faster than both Nvidia cards and the AMD Radeon R9 290X. Today we will look at the first partner card based on the 780 Ti from Inno3D.

Inno3D sent us their GeForce GTX 780 Ti iChill HerculeZ X3 Ultra 3GB, an overclocked version of the GeForce GTX 780 Ti, which already was the fastest card in the world. Let's see what it's capable of.

Special cooler

For the new card Inno3D used the HerculeZ X3 Ultra cooler, which we've seen previously on the Inno3D GeForce GTX 780 iChill. It takes up three slots and is equipped with three 9 cm fans. Measuring almost 30cm x 10 cm, it's a beast of a cooler. The heatsink has five 6mm heatpipes that transport the heat from the GPU to two separate parts of the heatsink. The three fans are controlled individually and take in air from the front and the side. This was done in order to make it possible to put two of these cards next to each other.

The side of the cooler, which will face the side panel with a window if your chassis has that, has a large iChill logo that lights up in white. A nice touch is the fact that you can replace the plexiglass plate with the logo, so casemodders can add their own design. The back of the card looks good too, with the aluminium plate.

The GPU of the standard GeForce GTX 780 Ti review is clocked at 876 MHz with a 928 MHz Boost clock frequency. The standard memory clock frequency of the 780 Ti is 1750 MHz. Inno3D kicks it up a notch and has increased the GPU speed by about 15 percent, to 1006 MHz and a Boost clock of 1072 MHz. The GDDR5 memory speed has been increased to 1800 MHz. 

The connectors are the same with two DVI ports, one HDMI and one DisplayPort. The card has one PEG6 and one PEG8 power connector.

At the time of writing the card is available for € 717 (£600), which is significantly more than a standard GeForce GTX 780 Ti that you can find for £564 / €650. It's not entirely surprising, because only a limited number of GK110 GPUs are capable of consistently running at the higher frequencies. That means extensive and time-consuming binning procedures have to be conducted to find viable chips for these iChill cards.
