In fact it’s more than even the GTX 780, a card that still beats the 280X Toxic in our benchmarks.įurMark shows a similar trend, with the 280X Toxic sustaining a load over 100W more than the stock 280X, or the GTX 780 for that matter. 339W (at the wall) under Metro is nearly 50W more than the stock 280X, and still 28W more than the overclocked (but not overvolted) Asus card. With the increased clockspeeds and voltages, rather expectedly we see an increase in power consumption. This is high for a Tahiti chip, and although still in the safe zone for something with this large an air cooler it is reaching about as high as we like to take Tahiti while maintaining longevity. This will also give us a chance to evaluate the costs of Sapphire’s significant factory overclock with respect to power consumption.Īt the base GPU clockspeed of 1110MHz Sapphire is able to stick to 1.2v for their GPU voltage, but to boost up to 1150MHz they have to go to 1.256v. Having seen the gaming performance of the 280X Toxic, let’s move on to power, temperature, and noise to get a better look at the performance characteristics of Sapphire’s Tri-X cooler.
