The Arm Mali-G57 GPU (graphics processing unit) is the first generation Valhall-based GPU for the mainstream market. Re-engineered to align with the Vulkan API, Mali-G57 brings higher-fidelity content to the mass market, from 4K/8K user interfaces in DTV to console-like graphics on smartphones. With 30% better performance density, 30% better energy efficiency for longer battery life, enhanced foveated rendering support for VR and up to 60% performance improvement for ML workloads, Mali-G57 pushes the boundaries on performance and efficiency for mainstream GPUs.

Scalability 1 to 6 dual-pixel cores
Optimized for high area and energy efficiency to address mainstream device requirements.
Adaptive Scalable Texture Compression (ASTC) Low Dynamic Range (LDR) and High Dynamic Range (HDR).
Supports both 2D and 3D images.
ASTC offers several advantages over existing texture compression schemes by improving image quality, reducing memory bandwidth and thus energy use.
Arm Frame Buffer Compression (AFBC) Version 1.3
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.
Foveated Rendering  3 levels of quality possible Foveated Rendering allows VR application to specify the shading rate to be used in each part of the screen. This helps the developer to reduce the workload of VR applications by selectively define the part of the screen that require less work from the GPU due to distortion introduced by the VR headset lenses.
