Image & Video Processing SDK for Tegra X2 mobile GPU
NVIDIA Tegra X2 is the latest mobile processor with high-performance Maxwell GPU architecture. Tegra X2 offers very high CPU and GPU performance to mobile computing. PC class imaging applications that require high performance, low energy consumption and large amounts of memory can now be developed for mobile devices with Tegra X2. We have ported our high performance Image & Video Processing SDK to Tegra and now we can offer super fast imaging solutions for Nvidia Tegra X2 GPU for realtime imaging and video applications.
Tegra X2 benchmarks for image and video processing
We have done measurements of kernel times for the most important components of GPU image and video processing SDK from Fastvideo. We utilized images with 2K and 4K resolutions and got the following averaged results. This is just a small set of features from what we have in our SDK.
