The Arm Mali-G31 GPU is an ultra-efficient GPU based on the Mali Bifrost architecture. Bringing the benefits of Bifrost to a different tier of device, Mali-G31 builds on the success of the previous ultra efficient products in the Mali-400 Utgard series. With significant energy and area savings compared to the next level of device, plus support for the very latest APIs, Mali-G31 is the GPU of choice for cost constrained devices.
Arm Mali-G31 GPU
|4x Multi-Sampling Anti-Aliasing (MSAA) with minimal performance drop.
OpenGL® ES 1.1, 2.0, 3.2
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-LITE and AXI||Compatible with a wide range of bus interconnect and peripheral IP.|
||8KB for MP1.
32KB-64KB for MP2.
|Memory System||Virtual Memory||Built-in Memory Management Unit (MMU) to support virtual memory.|
||1 uni-pixel core or dual-pixel core||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 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.|
Performance - Mali-G31
|Frequency||650 MHz||in 28nm HPM|
|Pixel/Texturing Throughput||1.3 Gpix/s||in 28nm HPM|
