GeForce GTX 780 Ti Summary
The ASUS card may be the last original GTX 780 Ti we get to test, so we want to compile a summary on all the products we’ve tested so far. The following table shows the ASIC quality of their GPUs, their default clock rates (including the actual clock rates according to our monitoring tools) and their overclockability results. The best numbers are colored red and the worst are blue. The cards are listed in the order of our testing them.
The reference Nvidia GeForce GTX 780 Ti has the highest-quality GPU chip (77.8%). The MSI GeForce GTX 780 Ti Gaming is the fastest card by default as its GPU clock rate can get as high as 1163 MHz. The fastest memory is installed on the Zotac and Inno3D but, as we’ve seen in our today’s tests, this factor doesn’t influence performance much.
As for overclockability, the Zotac has the highest GPU frequency result but the reference card has the highest frequency growth (+240 MHz). According to our monitoring tools, the highest GPU clock rate was achieved by the Inno3D, though. The ASUS card we've tested today is the best in terms of memory overclocking.
The next diagram shows the results of our temperature and noise level tests at the maximum speed of the fans and in the automatic fan regulation mode. The results are sorted in the order of ascending top GPU temperature.
The Inno3D wins in both fan regulation modes thanks to its fantastically efficient cooler. It is followed by the Zotac and Palit, although the latter is too noisy. The coolers from MSI and ASUS are comparable in efficiency but the MSI is quieter. The Gainward and Nvidia cards have the worst results in this comparison.
And the next diagram shows temperature and noise data for when the cards are overclocked. The fan speed of the reference Nvidia GeForce GTX 780 Ti was set manually at 85% (3530 RPM) for the sake of stability. We also increased the fan speed of the MSI card to 65% or 1920 RPM.
We’ve got the same leader here: the Inno3D enjoys a large lead over the second-best Zotac both in temperature and noise level. The Palit is third, but it has lower overclocking results than the Inno3D and Zotac cards and produces more noise. Next goes the MSI with manual fan speed regulation, followed by the cards from Gainward and Nvidia. The ASUS takes last place at overclocking but it is quieter than the Gainward, Nvidia and Palit.
If in the near future we get elite products from MSI’s Lightning, EVGA’s Classified K|NGP|N Edition and ASUS’s Matrix (MATRIX-GTX780TI-P-3GD5) series or this Gigabyte model, we’ll update this summary with new test results.
The ASUS GeForce GTX 780 Ti DirectCU II OC is an interesting product, even though it can hardly claim to be the best single-GPU Nvidia-based solution available. We've mentioned its downsides in the course of this review including its rather noisy cooler, unimpressive factory overclocking and low frequency potential. Otherwise, it is a well-made product with low operating temperatures, an original PCB with enhanced power system, informative and reliable packaging, and certain customization options concerning its appearance. The card is less expensive than other original GeForce GTX 780 Ti versions.
And one more fact we’ve learned from today’s testing is that overclocking a GTX 780 Ti’s graphics memory has but a very small effect on its performance.
