AMD Introduces Radeon RX 90-Series and Next-Gen FSR Technology

On March 5, AMD will launch its latest Radeon RX 90-series graphics cards, featuring the cutting-edge RDNA4 architecture. Alongside this release, AMD is set to unveil a new iteration of its popular FidelityFX Super Resolution (FSR) upscaling technology.

Both FSR and Nvidia’s Deep Learning Super Sampling (DLSS) share a common purpose: enhancing the visual quality of lower-resolution images rendered by graphics cards. They aim to upscale these images while filling in the details to simulate a native resolution appearance, alleviating the need for GPUs to perform intensive rendering tasks. While both technologies can introduce inconsistencies and may not perfectly replicate native resolution, they offer a considerable improvement over the alternative of displaying a blurry image on modern displays.

These upscaling technologies are particularly advantageous for users with older or budget-friendly GPUs operating at 1080p or 1440p resolutions, especially when connected to 4K monitors. Without these tools, gamers would have to choose between enjoying the clarity of a 4K output or maintaining a smooth frame rate. Additionally, they are beneficial for optimizing performance at lower resolutions, catering to the needs of high-refresh-rate gaming setups.

What sets FSR 4 apart from its predecessors is its utilization of hardware-supported machine-learning algorithms, a feature enabled by the new enhancements in the RDNA4 architecture and RX 90-series graphics cards. This strategy aligns with Nvidia’s approach with DLSS, which has consistently depended on specialized tensor cores on its RTX GPUs to enhance image quality through machine learning. It’s important to note that FSR 4 will only function with RDNA4-compatible GPUs, signaling a shift in how AMD approaches its upscaling technology.
