Sapphire HD7870 Overclock Edition Review

Allan 'Zardon' Campbell April 2, 2012 Featured Tech News, Graphics

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.

DLSS 5 NVIDIA

KitGuru Games: DLSS 5 misses the point

It would be hard to argue that NVIDIA’s DLSS technologies haven’t been a net positive to the PC space, with the machine-learning based upscaler successfully translating lower resolution inputs into a final image which is perceivably sharper while hogging fewer resources. Though somewhat more contentious, the next evolution of DLSS came in the form of Frame Generation, using ML in order to generate additional frames for high-refresh rate gaming. Both techniques can have their issues, but generally speaking they’ve allowed for more people to experience higher-end titles at increased frame rates. DLSS 5, however, takes a sharp pivot, with a very different end goal in mind than the performance-boosting versions that came before.

    Quality cards, but its a tough decision id have to base on price right now. as they all overclock much the same.

    Its XFX or Sapphire usually, but that gigabyte card is a solid buy,

    Only one problem. YOU CANT FIND IT ANYWHERE !!!”

    nice specs. good performance sapphire coolers seem a bit better than XFX coolers in regards to tempeatures.
