We will be testing both cards at there reference clockspeeds today along with the maximum stable overclocked speeds.





AMD usually have the advantage in clockspeeds and so it came as no surprise that the R7970 was the higher clocked of the two graphics cards at 1000MHz against the GTX580's 815MHz. Memory speed also favoured the XFX card with an effective speed of 5700 vs the 4104MHz of the ZOTAC card.

Both cards overclocked well but the XFX card had much more overclocking headroom despite it already being heavily clocked. These clockspeeds were rock solid stable throughout our testing but also under went and hour of MSI's Kombuster stressing programme to ensure the overclocks were thoroughly stable.

Enough of the talk now, let's see how both cards, at both sets of closkpeeds performed during testing...
