ARM® Mali™-T658 Graphics Processing Unit -8 core (GPU)

High efficient, smart GPU “ARM® Mali™-T658 Graphics Processing Unit” is announced by ARM on 10 Nov 2011 in Japan. This is the latest GPU after Mali-T604 GPU, ARM reported that Mali-T658 features four times the computation performance than Mali-T604 GPU and up to ten times the graphics performance of the Mali-400 MP GPU which is found in a wide range of today’s mainstream consumer products like ‘Galaxy S II’ and the new ‘Galaxy Note’. Mali-T658 GPU is the latest member of the Midgard architecture-based GPU family targeting high performance devices, such as superphones, tablets and smart-TVs.

Supported by lead ARM Partners, such as Fujitsu Semiconductor, LG Electronics, Nufront and Samsung, the Mali-T658 GPU enables an immersive visual computing experience on a range of ‘always on, always connected’ consumer devices. These include high-performance, energy-sensitive superphones, smartphones and tablets, as well as smart-TVs and automotive infotainment solutions. Building on the success of the Mali-T604 GPU, the Mali-T658 extends ARM performance leadership with scalability up to eight cores, and by doubling of the number of arithmetic pipelines within each of these cores. It is also compatible with the ARMv8 architecture. The ARM Mali-T658 GPU supports a wide range of graphics and compute APIs, including Microsoft DirectX® 11, Khronos OpenGL® ES, OpenVG™, Khronos OpenCL™, Google ® Renderscript ™ and Microsoft DirectCompute®.

One of the cool things about the Midgard architecture is the Job Manager – a clever little block in the GPU that takes the weight off the CPU by loading the data that the GPU needs autonomously, without requiring a big load on the CPU. The Job Manager issues jobs across the pipelines in the multicores depending on how many are fitted or powered up and down.

But, the products powered by a version with the maximum eight cores are expected to be introduced in 2015, according to a chart from ARM detailing the evolution of its mobile processors.
