AMD Radeon HD 7950 im Test (14/15)

Overclocking der XFX Radeon HD 7950 Black Edition

Wie viel Leistung lässt sich heraus kitzeln

Die XFX Radeon HD 7970 Black Edition war als OC Karte hervorragend zu übertakten. XFX Gibt in seinen Dokumentationen an, dass auf "Black Edition" Modellen die selektierten Top 1% der von AMD gelieferten GPUs verbaut sind. Dabei wird nicht nur darauf geachtet, dass die GPUs mit gesteigerter Spannung eine hohe Taktrate erreichen, sondern eben bei möglichst geringer Spannung eine möglichst hohe Taktrate, um den Verbrauch der Karte nicht zu hoch werden zu lassen. Viele Hersteller erhöhen einfach die Boardspannung, um entsprechende OC Karten auf den Markt zu bringen. Bei XFX werden die GPUs so selektiert, das dies möglichst nicht passiert.

Natürlich hat uns interessiert wie hoch sich die XFX Radeon HD 7950 Black Edition takten lässtund dazu haben wir uns dann auch gleich die neusten BIOSe, Treiber und Tools besorgt, um die Karte an ihre Grenzen zu Treiben. Bereits ohne das Anpassen der Spannung erreicht man leicht die 1100 MHz Marke absolut stabil.

Richtig ab geht es mit den korrekten Tools und BIOS, hier konnten wir den Speicher von eh schon hohen 1375 auf 1450 hoch drehen und den GPU Takt wie schon bei der Radeon HD 7970 auf satte 1300 MHz katapultieren. Damit wird die Karte zum absoluten Performance Monster, aber durch die notwendige Kühlung leider auch lauter. Hier merkt man auch deutlich den Unterschied zur deutlich stärkeren Kühlung der XFX Radeon HD 7970 Black Edition.

Die Leistungssteigerung die man durch Overclocking der Karte bekommen kann ist gigantisch und liegt bei sicherlich bis zu 30% - 40%. Dies zeigt sich jedoch nicht in allen Benchmarks, da es offenbar schon bei der sehr hohen Leistung der Karte zu einigen CPU Limitierungen kommt.

Mittlerweile lässt sich auch die Spannung des Speichers der XFX Karte verändern, was wir aus Zeitmangel aber nicht austesten konnten. Hier kann eventuell sogar noch mehr Performance aus dem Speicher herausgeholt werden.
