VTX3D HD7770 1GHZ Edition Crossfire Review

Allan 'Zardon' Campbell February 15, 2012 Featured Announcement, 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.

Power consumption is very good, averaging around 65 watts when gaming. When compared to the HD6790, the new HD7770 is more efficient, averaging around 15-20 watts less when gaming.

Fallout 4 Anniversary

Fallout 4: Anniversary Edition announced for all systems (including Switch 2)

Just under 10 years ago, Fallout 4 officially released to the world. While the game is far from perfect, it resonated with millions thanks to its sandbox-like design and focus on exploration among other ancillary additions (such as the settlement mechanic and base building). As they have done with many of their previous games, Bethesda has now officially announced Fallout 4: Anniversary Edition – bundling the base game alongside its DLC and hundreds of user-created mods.
