AMD Radeon HD 7660G + HD 7670M Dual Graphics vs AMD Radeon HD 7640G + HD 7670M Dual Graphics

AMD Radeon HD 7660G + HD 7670M Dual Graphics

► remove AMD Radeon HD 7660G + HD 7670M Dual Graphics

Die AMD Radeon HD 7660G + HD 7670M Dual Graphics bezeichnet die asymmetrische Crossfire Kombination aus AMD Radeon HD 7660G Prozessorgrafikkarte im AMD Prozessor und der dedizierten AMD Radeon HD 7670M Grafikkarte.

Beide Grafikkarten arbeiten bei der Grafiklösung im CrossFire Verbund und berechnen dadurch im AFR (Alternate Frame Rendering) Modus abwechselnd ein Bild. Deshalb leidet die Grafiklösung auch unter Microruckler bei Bildraten um die 30fps (unterschiedliche Abstände zwischen zwei Bildern führen zu Rucklern obwohl genug Bilder pro Sekunde berechnet werden). 

Die Performance der AMD Radeon HD 7660G und HD 7670M Dual Graphics ist stark abhängig von der Treiberunterstützung des eingesetzten Spiels oder der Applikation. Bei manchen Spielen kann die Leistung sogar 10-15% schlechter sein als mit einer Grafikkarte alleine. Bei guter Treiberunterstützung für das Spiel, kann man aber durchaus messbare Verbesserungen in der Framerate erkennen und sogar eine GT 640M übertreffen. Durch merkbares Ruckeln bei Frameraten um die 30fps (Microruckler) ist der Vorteil aber nur bei geringen Auflösungen / Einstellungen nutzbar.

Die Features wie PureVideo HD (UVD3) oder OpenCL Unterstützen entsprechen den beiden einzelnen Grafikkarten.

Da bei der Dual Graphics Grafiklösung unter Last beide Grafikkarten arbeiten, ist der Stromverbrauch deutlich höher.

Durch merkbares Ruckeln bei Frameraten um die 30fps (Microruckler) ist der Vorteil aber nur bei geringen Auflösungen / Einstellungen nutzbar. Im Optimalfall wird etwa die Performance einer GeForce GT 635M erreicht.
