Snapdragon Game Super Resolution Brings Upscaling to Mobile
Yesterday, mobile SoC maker Qualcomm announced a spatial upscaling tool called Snapdragon Game Super Resolution (GSR).
According to the San Diego-headquartered company, Snapdragon Game Super Resolution aims to maximize performance and battery life in mobile games. In a comparison image, Qualcomm likened it to AMD FidelityFX Super Resolution 1.0, though GSR can render in a single pass compared to FSR 1.0's two-pass operation, making it faster.
Since Snapdragon Game Super Resolution resolves edge sharpening and upscaling in one pass, power consumption is also reduced, and it's possible to combine it with additional post-processing effects such as tone-mapping, further enhancing performance.
The speed of GSR is owed to the upscaler using fewer textures samples and ALU instructions than rival upscalers. The luminance calculation only happens in the green channel since that's the color the human eye is most sensitive to, so GSR samples can use just a single component for each calculation, achieving 100% utilization of the shader processors.
As you would expect, Snapdragon Game Super Resolution runs best on Snapdragon Adreno GPUs thanks to specific optimizations for the Adreno GPU pipeline. However, it should work with 'most' mobile GPUs, Qualcomm said.
The company provided the following comparison benchmark, though it only refers to generic 'competitor upscalers', so it's hard to get a real bead. Anyway, it claims to be twice as fast. Gamers will be able to choose between running games at higher resolution (from 1080p to 4K, for example) than they were previously able to, or keep the same resolution but running at a higher frame rate, or just limiting the frame rate and conserving power to extend their device's battery life.
