NVIDIA GeForce GTX 780 Testing:
Temperature testing will be accomplished by loading the video card to 100% using Unigine's Heaven Benchmark Version 4.0, with MSI's Afterburner overclocking utility for temperature monitoring. I will be using a resolution of 1920x1200 using 8xAA and a five-run sequence to run the test, ensuring that the maximum thermal threshold is reached. The fan speed will be left in the control of the driver package and video card's BIOS for the stock load test, with the fan moved to 100% to see the best possible cooling scenario for the overclocked load test. The idle test will involve a 20-minute cool-down, with the fan speeds left on automatic in the stock speed testing and bumped up to 100% when running overclocked.
- Monitoring with MSI Afterburner
- Unigine Heaven 4.0 1920x1080 8x AA
- 5-run sequence
- 20-minute idle duration
- Temperature measured in degrees Celsius
The temperatures delivered by the HD 7970 comparison card are going to be lower due to the cooling solution employed by that card. What you see with the GTX 780 though are temperatures that are identical to the GTX 680 it is replacing in the product stack. When you overclock and overvolt the GTX 780 that uses the same cooling solution employed on the GTX Titan, it shows that less hardware in the core equates to better temperatures when the fan speed is maxed out. The GTX 780 was easily able to stay within thermal boundaries that maximize core clock speeds. One of the benefits of the GTX 780 is the ongoing work to improve acoustics as well as cooling. Normally you will hear the fans on the cooling solution speed up and slow down dynamically as you game. It's a fact of life, however NVIDIA has worked in a new adaptive temperature controller that aims to limit the up and down spikes in fan noise while keeping temperatures constant.
