Imagination's new PowerVR Series9 GPUs
Imagination Technologies announced its PowerVR Series9XEP, Series9XMP, and Series9XTP graphics processing units (GPUs). The three new Series9 GPU families range from entry-level to high-end and incorporate efficiency improvements and new features to deliver high performance.
PowerVR Series9 GPUs are designed to ensure class-leading graphics and smooth graphical user interfaces (GUIs) on products such as automotive infotainment products, smartphones, and TVs. The new GPUs include PowerVR Series9XEP, PowerVR Series XMP, and PowerVR Series XTP.
The PowerVR Series9XEP is based on the Rogue architecture and features PVRIC4 visually lossless compression to ensure reduced bandwidth and memory footprint. Target products include mid-range automotive dashboards and in-vehicle infotainment (IVI).
The PowerVR Series9XMP Rogue-architecture based GPUs are designed to have significantly increased compute density (GFLOPS/mm2) and provide the foundation for artificial intelligence (AI) and neural network processing.
The PowerVR Series9XTP is based on a development of the Furian architecture and has increased gaming/compute density and extensive power/performance/area (PPA) optimizations throughout the design.
PowerVR GPUs use a rendering technique called tile-based deferred rendering (TBDR), which keeps almost all image processing on-chip and minimizes memory bandwidth requirements. The new GPUs all incorporate PVRIC4 image compression technology that enables random-access visually lossless image compression, ensuring bandwidth and memory footprint savings of at least 50%, and enabling systems to overcome performance bandwidth constraints. The GPUs also offer enhanced performance/power/area and timing improvements versus previous generation GPUs, as well as new features including a new alpha buffer/block hint feature for reduced composition workload bandwidth and cost.
The new GPUs can be paired with the PowerVR Series3NX Neural Network Accelerator (NNA), using the GPU to manage classic vision and pre-processing algorithms and the Series3NX to handle highly optimized fixed point neural network processing.
The optimizations in the recently announced PowerVR Automotive pack can be applied to any of these PowerVR Series9 cores.
