Mali-T820 and Mali-T830 High Area Efficiency GPUs

Mali-T820 and T830 Block Diagram.

About Mali-T820 and Mali-T830

The Arm Mali-T820 and Mali-T830 GPU provided a staggered approach to performance, providing significant improvements over previous generations. The Mali-T820 and Mali-T830 GPU were the first mainstream Mali GPUs to introduce support for OpenGL ES 3.2 API, Android Extension pack support and Arm Framebuffer Compression support. On this page you will find specifications and performance data for Mali-T820 and Mali-T830 GPU and if you are developing on this GPU, you can also request support and guidance on our forums below.  

The Mali-T820 and Mali-T830 GPU is not advised for new designs, but may still be popular in devices all over the world and still quite relevant for modern day developers. If you are looking for a modern similar GPU we suggest the Mali-G57 GPU.

Mali-G57 GPU

Specification

 Features  Value Description
Anti-Aliasing
4x MSAA. 4x Multi-Sampling Anti-Aliasing (MSAA) with minimal performance drop.
API Support
OpenGL® ES 1.1, 2.0, 3.1, 3.2.
Vulkan 1.0.
OpenCL™ 1.1, 1.2 Full Profile.
RenderScript™.
Support for a wide range of graphics APIs.
Bus Interface
AMBA®4.
ACE-Lite.
Compatible with a wide range of bus interconnect and peripheral IP.
L2 Cache
Configurable 32KB-256KB.
64KB-128KB for MP1 & MP2.
64KB-256KB for MP3.
128KB-256KB for MP4.
Memory System
Virtual Memory. Built-in Memory Management Unit (MMU) to support virtual memory.
Multi-Core Scaling
1 to 4 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 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 locates identical pixel blocks from 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.
