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.
Sapphire's HD7750 Ultimate Edition requires less power than the reference design card we have in our labs. 2 watts less when gaming and around 4 watts less when under Furmark load.
AMD would be completely lost without Sapphire fixing their messes at times.
Good read. Any chance they could release a passively cooled HD6970 🙂 ?
Heatsink is good, but would that sticker not need to be removed before using it? might melt into the fins.
Great product, good old sapphire never fail to deliver the goods for media buffs.
Ok ill probably get attacked for this, but here it goes.
Why not passively cool the hD7770? I cant see how it runs too hot for a passive cooler.
