Specifications

Arm Mali-G71 was the first premium GPU to implement the Mali Bifrost architecture. Bifrost enabled high-end mobile GPUs with the ability to deliver extra computational performance. This extra performance was used to address the ever advancing complexity of modern use cases such as VR and high fidelity gaming. Bifrost enabled these use cases without draining the battery at a high rate or exceeding the thermal budget of the device.

Memory System
Virtual Memory. Built-in Memory Management Unit (MMU) to support virtual memory.
Multi-Core Scaling
1 to 32 cores.
Optimized for high energy efficiency to address the high-end mobile and consumer device requirements.
Adaptive Scalable Texture Compression (ASTC)
Low Dynamic Range (LDR) and High Dynamic Range (HDR).
Supports both 2D and 3D images.
ASTC offers a number of advantages over existing texture compression schemes by improving image quality, reducing memory bandwidth and thus energy use.
Arm Frame Buffer Compression (AFBC)
4x4 pixel block size. AFBC is a lossless image compression format that provides random access to pixel data to a 4x4 pixel block granularity. It is employed to reduce memory bandwidth both internally within the GPU and externally throughout the SoC.
Transaction Elimination
16x16 pixel block size.
Transaction Elimination spots the identical pixel blocks between two consecutive render targets and performs a partial update to the frame buffer with the changed pixel blocks only, which reduces memory bandwidth and thus energy.
Smart Composition
16x16 pixel block size.
Smart Composition extends the concept of Transaction Elimination to every stage of UI composition. Identical pixel blocks of input surfaces are not read, not processed for composition and not written to final frame buffer.
