PERFORMANCE
Performance at 4K
The RTX 5080 at 4K reaches 122 FPS in Resident Evil 4, 112 FPS in Final Fantasy XIV: Dawntrail, 84 FPS in Dragon's Dogma 2, 81 FPS in Dying Light 2, and 76 FPS in Starfield, per GamersNexus. The GPU has a 360 W TGP (Total Graphics Power) and 16 GB of VRAM.
At 4K, 16 GB of VRAM is sufficient for most current games at 4K, with ray tracing settings depending on the title and optimisation. The Ryzen 7 9800X3D's 3D V-Cache keeps per-frame CPU time short, so the RTX 5080 is not CPU-limited in gaming workloads.
The 64 GB of DDR5 RAM and the Samsung 9100 Pro 4 TB Gen 5 NVMe SSD also position this build for video editing, 3D rendering, and content creation alongside gaming. Gen 5 NVMe is the current fastest generation of consumer storage.
"The GeForce RTX 5080 is designed for maxed out gaming at 4K Ultra HD, including with ray tracing."
