PowerVR GT7200 Plus and GT7400 Plus GPUs Support OpenCL 2.0, Better Computer Vision Features

Imagination Technologies introduced PowerVR Series7XT GPU family with up to 512 cores at the end of 2014, and at CES 2016, they’ve announced Series7XT Plus family with GT7200 Plus and GT7400 Plus GPUs, with many of the same features of Series7XT family, plus the addition of OpenCL 2.0 API support, and improvements for computer vision with a new Image Processing Data Master, and support for 8-bit and 16-bit integer data paths, instead of just 32-bit in the previous generation, for example leading to up to 4 times more performance for applications, e.g. deep learning, leveraging OpenVX computer vision API.

GT7200 Plus GPU features 64 ALU cores in two clusters, and GT7400 Plus 128 ALU cores in a quad-cluster configuration. Beside OpenCL2.0, and improvements for computer vision, they still support OpenGL ES 3.2, Vulkan, hardware virtualization, advanced security, and more. The company has also made some microarchitectural enhancements to improve performance and reduce power consumption:

  • Support for the latest bus interface features including requestor priority support
  • Doubled memory burst sizes, matching the latest system fabrics, memory controllers and memory components
  • Tuned the size of caches and improved their efficiency, leading to a ~10% reduction in bandwidth

The new features and improvements of PowerVR Series7XT Plus GPUs should help designed better systems for image classification, face/body/gesture tracking, smart video surveillance, HDR rendering, advanced driver assistance systems (ADAS), object and scene reconstruction, augmented reality, visual inspection, robotics, etc…
