Multi-Core Scaling | 1 to 4 cores. | Optimized for high area and energy efficiency to address mainstream device requirements. | 1 uni-pixel core to 3 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). | ASTC offers a number of advantages over existing texture compression schemes by improving image quality, reducing memory bandwidth and thus energy use. | Low dynamic range (LDR) and high dynamic range (HDR). | 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. | Version 1.2 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. | 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. | 16x16 pixel block size | Smart Composition extends the concept of Transaction Elimination to every stage of UI composition.
