In brief: AMD has officially confirmed that the models used to develop FSR4, the latest version of its upscaling technology, were designed in collaboration with Sony. The company posted the news on X, revealing that a lot more is coming from this partnership.
“FSR 4 is looking fantastic! Excited for the co-development with Sony Interactive Entertainment on the models used for the FSR 4 upscaler. This is just the beginning. Stay tuned for what’s next,” reads the post.
For some context, PlayStation lead architect Mark Cerny unveiled Project Amethyst in December, a joint machine learning initiative between AMD and Sony. The project is centered on two main objectives: The first is to develop hardware architectures optimized for efficiently handling machine learning workloads. The second is co-developing high-quality convolutional neural networks (CNNs) specifically designed to enhance gaming graphics.

The idea was that both companies could leverage this shared pool of ML architectures, training strategies, and models for their own products down the line. On the PlayStation side, this likely ties into the AI-accelerated upscaler in the PS5 Pro called Spectral Super Resolution (PSSR). Perhaps Sony aims to integrate some FSR 4 tech to further improve its PSSR algorithm.
Happy Radeon Day! We’re proud to collaborate with @PlayStation on Project Amethyst! 🔥

For AMD, the FSR 4 models were trained in collaboration with Sony’s experts to enhance the upscaling and anti-lag performance we’re seeing on AMD’s latest GPUs. AMD says this is just the start – more exciting tech is coming from this partnership.
It’s a win-win for both companies. Sony gets to leverage AMD’s latest AI upscaling know-how for its consoles, while AMD gains from Sony’s experience with optimizing graphics for gaming workloads.
Of course, we also can’t forget that AMD has been supplying chips for PlayStation consoles dating back to the PS4 days. The current PS5 and PS5 Pro both feature customized AMD Zen 2 CPU and RDNA 2 GPU silicon. This Amethyst collaboration furthers the two companies’ already tight relationship in the gaming space.
On the PC graphics front, AMD has started shipping its new midrange RX 9070 XT and 9070 GPUs that offer FSR 4 upscaling. The XT model packs 64 compute units running at up to a 3GHz boost clock for $599, while the non-XT has 56 CUs at up to 2.5GHz for $549. Both come equipped with a hefty 16GB of GDDR6 VRAM to power solid 1440p gaming performance with FSR 4 enabled.
Lower-end RX 9060 series GPUs were announced at CES too, but pricing and availability are still under wraps for those budget-friendly options.
