Furian is designed to enable a new generation of consumer devices to deliver high-resolution, immersive graphics content and data computation for sustained time periods within mobile power budgets. The two-cluster GT8525 offers class-leading performance, power and area, as well as features for customers designing SoCs for products such as high-end smartphones and tablets, mid-range dedicated VR and AR devices and mid- to high-end automotive infotainment and ADAS systems.

 

The Furian architecture has been designed for the evolved graphics and compute needs of next-generation consumer devices:

In smartphones: the GT8525 addresses the need for continuous improvements in sustained performance for gaming in constrained power footprints, including for mobile VR uses. It also allows new mobile use cases requiring greater compute availability, such as the use of neural networks (including CNNs) for object identification.

In automotive: with dramatically increased compute efficiency and built-in hardware virtualization, the GT8525 addresses the increasing trend toward combining infotainment with electronic dash and some ADAS functionality on the same SoC. OEMs can enable isolation of concurrent functions and services to ensure greater safety and security while saving on valuable silicon area.

For AR/VR: the GT8525 provides the high resolution and high sustained frame rate graphics required for a great user experience on standalone AR/VR headsets. The GT8525 includes hardware and software specifically designed for minimizing the critical motion-to-photon latency. With devices based on the GT8525, OEMs can offer higher performance graphics and compute in an area efficient manner. Developers can exploit the power of the OpenVX* API on PowerVR for rapid application development.

 

Compared to the Series7XT GT7200 GPU, the GT8525 achieves:

– More than 50% fps improvement on the industry-standard Manhattan benchmark test, one of the de-facto benchmarks for mobile and other applications, and 80% TRex

– More than 50% improvement in fps for the Antutu benchmark – another key benchmark

– 2x PPC throughput (8 pixels/clock compared with 4 for GT7200), allowing for higher resolutions, and additional performance for previously fill rate limited use cases

– 50% more GFLOPs, and more accessible GFLOPs, enabling easier exploitation of the cores full potential for graphics and compute

 

Furian continues use of Imagination’s Tile Based Deferred Rendering (TBDR), which the company says has been proven over multiple generations of PowerVR GPUs to provide the most highly efficient embedded graphics.

Furian also features a new 32-wide ALU cluster design for increased performance density and efficiency. A new instruction set architecture (ISA) in the primary and secondary ALU pipelines enables improved utilization of resources and thus efficiency, and multi-threading optimizations allow efficient and very flexible access to on-chip local compute memory. Furian is designed to address the increasing compute requirements across multiple applications and market segments with efficient use of compute APIs including OpenCL 2.0, Vulkan 1.0 and OpenVX 1.1.
