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 GPU and Arm Mali-T830 GPU provide a staggered approach to performance, providing significant improvements over previous generations. The Mali-T830 GPU has more compute capability per shader core and handles more complex content than the Mali-T820 GPU. The Mali-T820 GPU and Mali-T830 GPU are the first mainstream Mali GPUs to introduce OpenGL ES 3.2 API support, Android Extension pack support and Arm Framebuffer Compression support.

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.

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.
