In the second half of this year promise to appear devices based on the new processors from Qualcomm - Snapdragon quad 805. As we have noted , the new SoC include the graphics system. GPU Adreno 420. Changes quite a lot. This support for hardware tessellation and dedicated interface memory access (to use this GPU common bus with image processing and video codecs), and work with OpenGL ES 3.1, OpenCL 1.2 and Direct3D 11.2, as well as support for the new texture compression technology - ARM Adaptive Scalable Texture Compression (ASTC).
Coupled architectural improvements promise Adreno 420 reduced by 20% TDP while maintaining the performance level of Adreno 330 or increase productivity by 40%. Snapdragon platform 805 can easily display images with the quality of 4K to compatible TVs. However, they will not pull a lot of energy from the battery, as Snapdragon 805 embedded hardware codec H.265 HEVC.
Immediately make a reservation, that the lack of optimization software has not allowed to turn Snapdragon 805 in all its glory. First of all, it concerns the majority of test cores and systems in general. For example, at medium quality settings in the test Basemark X 1.1 difference in performance between the Adreno 420 and 330 reaches 25%. In the case of high-quality gap increases to 50%.
