Beyond graphics improvement, the Imagination team found that many modern games spend significant time on post-processing algorithms for blur, depth, and additional effects. Most of these algorithms are bottlenecked by the throughput rate of the texture processing unit (TPU).
IMG DXT's TPU creates a so-called "fast path" for these post-processing effects. The TPU doubles the performance only when the hardware detects regular processing across a region. These regions reuse processing points with texture cache and 2D sampling of a single texture with no detail or perspective. It accelerates tasks such as post-processing effects in games and computational photography filter processing. It improves image quality with faster and more power-efficient noise-eliminating algorithms.
With all these new technologies, IMG DXT cores exhibit 20% better performance density per area than Imagination's last generation of GPUs, the IMG CXT, while reducing power consumption. The DXT-72-2304 configuration delivers 72 GTexels/s and 2.5 TFLOPs of FP32 arithmetic performance, with a 50% higher maximum single-core performance than the CXT GPUs.
