IMAGINATION TECHNOLOGIES has announced its next generation GPUs, the PowerVR Series7 GT7200 Plus and GT7400 Plus, based on the firm's latest Rogue architecture as seen on the likes of Intel Atom and MediaTek smartphone chips.
The graphics processors are part of the new PowerVR Series7XT Plus family, which Imagination calls "state-of-the-art, high-end GPUs" aimed at the premium and mid-range segments of the consumer electronics market.
The GT7200 Plus is a dual-cluster configuration sporting 64 ALU cores, while the GT7400 Plus is a quad-cluster graphics processor counting 128 ALU cores. Imagination said that both designs retain the full feature set of their Series7XT counterparts (e.g. OpenGL ES 3.2 and design for Vulkan support, hardware virtualisation, advanced security etc.) while introducing a number of new features aimed at vision and heterogeneous computing platforms.
However, one of the main features of the new GPUs is the introduction of an integer pipeline for vision-related applications and hardware support for the OpenCL 2.0 compute API.
"Computer vision is going to be the next big thing in computing, touching everything from computational photography on mobile devices (think super-fast and better Instagram filters or more realistic VR) to implementing advanced AI in drones, robots and self-driving cars," said the firm in its announcement at CES 2016.
"Therefore the GPU must evolve from a simple pixel pusher to a highly complex computational engine. This is why we've tuned the feature set of our new PowerVR Series7XT Plus to dramatically improve performance by up to four times for next-generation computer vision applications."
Imagination said that it has also made "significant micro-architectural enhancements" to improve system performance and reduce power consumption.
These include: 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; and tuned caches to improve efficiency, leading to a proposed 10 percent reduction in bandwidth. µ
