In A8X processor uses 8-cluster graphics proprietary Apple
AnandTech experts studied the latest processor integrated circuit A8X, which is used in the iPad Air 2. They came to the conclusion that in the top 10-inch Apple tablet is used not graphics accelerator PowerVR GX6650, as previously thought, and its more powerful version.
The picture shows the integrated circuit can be seen A8X eight clusters GPU – twice more than the GPU Apple A8 in the iPhone and the iPhone 6 6 Plus. Smartphones are equipped with the latest generation module Technologies GX6450 .
In the line of Imagination Technologies Series6XT most powerful model is the PowerVR GX6650. Experts suggest that he joined the flagship aypada. However, now it is a non-default configuration, assembled by Apple. They managed to fit in a single module just two chipset GX6650. This configuration conventionally called PowerVR GXA6850. In an 8-GPU cluster number of ALU-cores increased from 192 to 256.
Thus, Apple created a graphics accelerator chipset A8X by the number of shader cores of clusters and caught up with the PowerVR GT7800 – a model of generation Series7XT announced on the eve of the new architecture Rogue7. What is not the PowerVR GT7800, excluded, as Imagination Technologies promised appearance of graphics cards in this series smartphones and tablets until next year.
Tests confirmed that the iPad Air 2 is a very powerful graphics processor. Results in benchmarks GFXBench 2.7 T-Rex and 3.0 Manhattan showed that in some cases the GPU iPad Air 2 bypasses even graphics tablet Nvidia Shield Tablet, which is installed chipset Tegra K1. Last GPU architecture with full Kepler claims to performance worthy of the Xbox 360 and PS3. Nvidia Shield Tablet was able to bypass iPad Air 2 only onscreen-tests due to the lower resolution display.
Earlier benchmark Geekbench 3 confirmed that the processor is A8X tricyclic and operates at a clock frequency of 1.5 GHz. Amount of RAM appeared at 2 GB. As for the immediate performance results when compared iPhone and iPhone 6 6 Plus, Markets A8 chips, there have iPad Air 2 observed a significant increase in computing power.
The new Apple tablet scored when tested in single-core mode and 1812 points is absolutely a record for this class of devices 4477 points in the multi-core. The corresponding figures for the iPhone 6 constitute 1609/2879 points, and for iPhone 6 Plus – 1596/2854.
