PowerVR AX2145

PowerVR Neural Network Accelerator

Optimised for cost-sensitive devices

The PowerVR AX2145’s streamlined architecture delivers performance-efficient neural network inferencing engine for ultra-low bandwidth systems making it the ultimate choice for entry-level and mid-range.

Its highly tuned tensor processing and convolution engines combined with an optimised core memory infrastructure can deliver outstanding maximum performance of 1 TOPS, but with a 50% better inference performance per mm2 than the AX2185 in systems with low peak memory bandwidth (as measured in GB/s).
