Oh wow Oo
"Nick Mertes at Icrontic says “We say “almost completely” because there are indeed certain hardware differences between the original and Gigahertz editions. The newer cards have improved sensors for more accurate PowerTune adjustments—but that’s the only physical difference. In all other respects, the upgrade should provide the Gigahertz Edition benefits to the older standard 7970 GPU:
- A higher GPU clockspeed of 1000MHz, up from the 7970′s 925MHz.
- A higher memory clockspeed of 1500MHz, up from the 7970′s 1375MHz.
- And PowerTune’s new “Boost” feature, which allows the graphics to dynamically overclock itself up to 1050MHz if the GPU has thermal headroom."
Pretty sick!
