To test power consumption today we are using a Keithley Integra unit and we measure power consumption from the VGA card inputs, not the system wide drain. We measure results while gaming in Crysis Warhead and record the results.
In such an energy aware climate, AMD are making a big deal out of their new ‘ZeroCore Power’ technology. Many solutions today use power gating, clock gating and memory compression to reduce idle power requirements, but ZeroCore power technology can completely power down the core GPU while the rest of the system remains active.
The Sapphire HD7870 Overclock Edition demands around 144 watts when gaming, which is fairly efficient considering the performance levels.
Another good card from the Sapphire team 🙂
Great cards. My friend bought one and its really quiet. the coolers are great this year.
Bought the 7970 last week 🙂
Quality cards, but its a tough decision id have to base on price right now. as they all overclock much the same.
