The Arm Mali-G68 GPU is a Valhall architecture-based GPU for sub premium devices. Mali-G68 enables complex use cases from high fidelity graphics to machine learning (ML) and is supported by all the latest APIs, such as Vulkan and OpenCL. It allows premium features to be scaled across the sub-premium market at a strong performance point.
With support for up to 6 core designs, Mali-G68 ensures that graphics to run smoother across a broad range of devices. In addition, a new Fused Multiply-Add (FMA) unit in the execution engine is built from ground up, leading to a further 30% energy reduction in the unit.
Arm Mali-G68 GPU
|4x Multi-Sampling Anti-Aliasing (MSAA) with minimal performance drop
|API support||OpenGL® ES 1.1, 2.0, 3.1, 3.2
Vulkan 1.1, 1.2
OpenCL™ 1.1, 1.2, 2.0 Full profile
|Full support for next-generation and legacy 2D/3D graphics applications
|Bus interface||AMBA®4 ACE, ACE-LITE, and AXI||Compatible with a wide range of bus interconnect and peripheral IP
|L2 cache||Configurable 512KB – 2MB
||2 or 4 slices
||Configurable from 6 cores delivering a specific capability for a Mali GPU.|
|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
