  This paper introduces a novel benchmark as part of the AIS 2024 Real-Time
Image Super-Resolution (RTSR) Challenge, which aims to upscale compressed
images from 540p to 4K resolution (4x factor) in real-time on commercial GPUs.
For this, we use a diverse test set containing a variety of 4K images ranging
from digital art to gaming and photography. The images are compressed using the
modern AVIF codec, instead of JPEG. All the proposed methods improve PSNR
fidelity over Lanczos interpolation, and process images under 10ms. Out of the
160 participants, 25 teams submitted their code and models. The solutions
present novel designs tailored for memory-efficiency and runtime on edge
devices. This survey describes the best solutions for real-time SR of
compressed high-resolution images.
