Nvidia GTX780Ti Review (1600p, Ultra HD 4K)

The tests were performed in a controlled air conditioned room with temperatures maintained at a constant 24c – a comfortable environment for the majority of people reading this.Idle temperatures were measured after sitting at the desktop for 30 minutes.Load measurements were acquired by playing Crysis Warhead for 30 minutes and measuring the peak temperature. We also have included Furmark results, recording maximum temperatures throughout a 30 minute stress test. All fan settings were left on automatic.


The Nvidia GTX 780 Ti runs a little hotter than the reference GTX Titan and GTX 780, but when gaming it never pushed past 77c under load, in our specific environment. This is a significant improvement over the reference AMD R9 290X/290 cooler. Nvidia partners are also likely to be releasing improved GTX780 Ti cooling solutions over the coming months which will further drop load temperatures.

There is quite a discrepancy between the load temperature results when looking at the single fan R9 290 reference cooler (95c when gaming) and the single fan GTX 780 Ti reference cooler (80c when gaming). Nvidia explain that the AMD solution draws a lot of power and that dissipating this is a challenge for AMD because the 290 has a smaller die size. (455 square millimeters against 533 square millimeters from the GTX 780 Ti).

Nvidia sent over the image above, which shows thermal density comparison. This highlights the power per square millimeter, measured in watts per square mm of die area. The image shows that the R9 290X has a higher rating of 0.64 compared against the GTX 780 Ti 0.47 rating.
