Mali GPUs are found in more than 50 percent of Android tablets and more than 20 percent of Android smartphones and ARM has tuned the Mali-T720 GPU specifically for Android. It is derived from the Mali GPU found in the Samsung Galaxy Note 3 and cost-optimized for entry-level Android devices developed to reduce an OEMs’ manufacturing complexities and time-to-market.
“Today, ARM Mali GPUs enable a stunning and aesthetic UI in many of Samsung Exynos Processors,” said Taehoon Kim, vice president of System LSI marketing at Samsung Electronics. “Mali GPUs continue to enhance the user experience on the mobile environment.”
It provides 150 percent energy efficiency increase over the ARM Mali-400 GPU and faster implementations through high routing density and a simplified design. The die area is reduced by almost 30 percent while increasing graphics performance above 50% over previous cost optimized graphics processors and it brings APIs such as OpenGL ES 3.0, OpenCL and RenderScript to the low-end smartphone market for the first time.
“ARM Mali GPUs unit shipments have increased by more than 10x over the past two years and it is the unquestioned leader in Android devices today,” said Pete Hutton, executive vice president and general manager, Media Processing Division, ARM. “The Mali-T700 Series family builds on our industry leadership in balancing power, area and functionality while incorporating new energy-saving features at the high-end and matching the time-to-market dynamics of the low-end. This combination gives our SoC partners a competitive edge, without compromising on performance and energy-efficiency.”
The physical IP support offers area-optimized implementations balancing low power and performance initially targeting TSMC 28HPM process technology for entry level designs.
LG Electronics, MediaTek and Rockchip are among the lead licensees for the latest Mali GPUs, although with more of a focus on the high performance core on 28nm and 16nm FINFET processes.
The Mali-T760 GPU increases the energy efficiency and performance of approximately 400 percent over the ARM Mali-T604 GPU and scales to 16 shader cores, which doubles the previous generation, plus an increase in both performance per shader core and overall performance. Bandwidth reduction comes from the ARM Frame Buffer Compression (AFBC), and Smart Composition that only updates tiles when they change, leading to a 50 percent reduction in total memory bandwidth utilization. This also reduces the wire count and layout congestion for larger core count implementations, accelerating time to market;
ARM’s POP IP for ARM Mali-T760 GPU will speed development and shorten implementation for market-leading performance implementations initially targeting TSMC 28HPM and TSMC 16FF process technologies, and it interfaces with the ARM CoreLink CCI-400 Cache Coherent Interconnect.
“Rockchip services mass markets and consumers that demand the latest Android features and highest performance,” said Feng Chen, chief marketing officer at Rockchip. “The simplicity and feature rich design of the Mali-T760 GPU enables Rockchip to quickly bring new SoCs to market with the latest Android advantages in a wide range of mobile devices.”
