AMD Radeon RX 9050 4GB
So, is the Radeon RX 9050 4GB as bad as we expected? Yes. In some respects, it's even worse. The most surprising result was Rainbow Six Siege X, where VRAM capacity clearly wasn't the primary limitation. The RX 9050 8GB averaged 180 fps, while the 4GB model managed just 111 fps, despite the game not coming close to exhausting a 4GB VRAM buffer. Meanwhile, the 4GB and 8GB versions of the RX 6500 XT delivered identical performance.
