NVIDIA GeForce GTX Titan Video Card ReviewThu, Feb 21, 2013 - 9:00 AM
For testing power consumption, we took our test system and plugged it into a Kill-A-Watt power meter. For idle numbers, we allowed the system to idle on the desktop for 15 minutes and took the reading. For load numbers we measured the peak wattage used by the system while running the OpenGL benchmark FurMark 1.10.4 at 1024×768 resolution in full screen mode. We also ran four game titles at 1920×1080 and averaged the peak results recorded the highest Wattage seen on the meter for the gaming results.
Power Consumption Results: The NVIDIA GeForce GTX Titan has amazing power efficiency numbers compared to the other four high-end graphics cards that we compared it to today. Seeing a 250W TDP card idling at just 99 Watts was amazing. Thanks to the new temp target feature on the NVIDIA GeForce GTX Titan we found the load power use to be very easy to monitor and it was always around 390 Watts. This really isn’t much more power than the ASUS GeForce GTX 680 Top edition card was using and the performance was 20-40% higher in pretty much all of of tests! The performance versus power use on the NVIDIA GeForce GTX Titan is certainly one of the cards best assets. The NVIDIA GeForce GTX 690 was faster on our 2560×1600 monitor, but notice that it uses roughly 60 Watts more power at load and around 12 Watts at idle. If you are building a small form factor system the GeForce GTX Titan’s less power use and shorter board length (half an inch) might be the best fit for you.
