Every product within ARM’s broad range of GPUs scales to deliver a rich user experience to consumers of both premium devices and affordable smartphones. The Mali-T820 & Mali-T830 offer advanced GPU technology to consumers of mainstream devices. The Mali-T820 enables attractive, fluid user interfaces and smooth casual gaming in the smallest silicon area. By reducing the cost of implementation, the Mali-T820 brings feature-rich complex graphics to mainstream consumers. It has been designed to include specific performance optimizations both for casual content and 2D UIs and for more advanced content.
Thanks to its additional arithmetic pipeline, the Mali-T830 is able to compute arithmetically complex content faster than the Mali-T820. It brings advanced 3D gaming and other arithmetically complex use cases to consumers of mainstream smartphones, tablets and DTVs, and delivers maximum performance within a minimal silicon area. Further performance optimizations such as quad prioritization and advanced early Z testing help to deliver a 55% performance improvement over the Mali-T622 in the same configuration and process node.
In addition to improving performance density over previous generations, the Mali-T820 & Mali-T830 introduce energy saving features such as AFBC and Smart Composition to the High Area Efficiency roadmap for the first time. Such technologies are important in order to ensure that as graphics content across the entire scale of mobile devices continues to become more complex, every system is able to handle new requirements in an energy efficient manner. For example, AFBC has the ability to reduce overall system level bandwidth consumption and power cost of transferring spatially coordinated image data throughout the system by up to 50%.
With native hardware features such as 10-bit YUV support, the Mali-T820 & Mali-T830 are an ideal accompaniment to the Mali-DP550 and Mali-V550 in addressing the requirements of an increasingly 4K DTV and STB market. Native 10-bit YUV support enables high fidelity 4K display without the need to perform intermediate conversions in software, thus ensuring the multimedia system delivers quality high resolutions at lower bandwidth levels.
The ARM Mali-T820 & Mali-T830 GPUs offer full support for current and next generation APIs, enabling advanced 3D graphics acceleration and GPU Compute functionality. This includes support for the Khronos OpenGL ES 3.2*, 3.1/2.0/1.1, Vulkan 1.0* and OpenCL 1.1/1.2* Full Profile APIs. Additionally support is provided for the Android Extension Pack, Android Renderscript and Microsoft Windows DirectX11 FL9_3. These APIs are fully supported by proven Mali GPU DDKs, which are provided under a standard ARM commercial license to all Mali GPU customers, ensuring a simple transition to the Mali-T820 and Mali-T830 from previous generations of Midgard GPUs.
Furthermore, when designing an ARM-based SoC with an ARM Cortex® CPU and ARM Mali GPU, Video and Display Processors, the Android driver for each processor works efficiently together. This optimized Android multimedia stack removes the challenge of integrating and optimizing processors from different suppliers and simplifies the task of supporting regular Android updates. By taking advantage of ARM’s pre-optimized software, partners can focus on differentiating their solutions and bring their product to market sooner.
