Qualcomm Adreno 420

Qualcomm Adreno 420

Der Qualcomm Adreno 420 ist eine im Qualcomm Snapdragon 805 SoC integrierte Grafikkarte für Smartphones und Tablets. Sie wurde gegen Mitte 2014 offiziell vorgestellt und wird hauptsächlich in Android basierten Geräten eingesetzt. Neu ist gegenüber der Adreno 330 die Unterstützung für OpenGL ES 3.1, DirectX 11 Feature Level 11_2 und damit Hardware-Tessellation. Die Grafikkarte nutzt weiterhin eine Technologie namens FlexRender. Diese kann "intelligent" zwischen TBR (Tile Based Renderer) und klassischem direkten Rendern umschalten. Die Grafikkarte hat außerdem nun einen eigenen direkten Anschluss an das Speicherinterface (bis jetzt musste sie ihn sich mit dem ISP und Video Engines teilen).

Die Taktrate der Adreno 420 ist abhängig vom konkreten SoC, der den Grafikchip integriert. Zu Beginn findet man sie z.B. im APQ8084 mit bis zu 600 MHz. Laut Qualcomm sind jedoch auch Varianten mit 500 MHz möglich.

Qualcomm gibt an, bis zu 20% weniger Strom im GFXBenchmark 2.7 T-Rex als der ältere Snapdragon 800 (Adreno 330) zu brauchen, aber trotzdem ein bis zu 40% höheres Ergebnis zu erhalten. Erste Benchmarks bescheinigen der GPU sogar noch größere Leistungszuwächse; allerdings wird die maximale Performance insbesondere in Smartphones nur kurze Zeit gehalten. Bei dauerhafter Auslastung sinken Takt und Framerate oft merklich ab, um die Temperaturentwicklung zu begrenzen. Dennoch ist die Adreno 420 Mitte 2014 eine der schnellsten mobilen GPUs und übertrifft sowohl die ARM Mali-T628 MP6 (Samsung Exynos 5420/5430) als auch die PowerVR G6430 (Apple A7). Einige Tablet-Chips wie die PowerVR GXA6850 (Apple A8X) sowie Nvidias Tegra K1 sind allerdings nochmals merklich schneller.
