TL;DR: AMD's FSR 4 AI upscaling, officially using FP8 format on RDNA 4 GPUs, now unofficially runs in INT8 mode on RDNA 2 and 3 hardware, improving image quality over FSR 3.1 with moderate performance ...
TL;DR: AMD's FSR 4 AI upscaling offers significant performance gains and improved image quality over FSR 3.1, especially on RDNA 4 GPUs. An unofficial INT8 FSR 4 version extends compatibility to RDNA ...
This is important because: If AMD makes an INT8 path official, the upgrade lands on hardware people already own. That includes Xbox and portable PCs, where modest resolutions are common and every ...
INT8 provides better performance with comparable precision than floating point for AI inference. But when INT8 is unable to meet the desired performance with limited resources, INT4 optimization is ...
