How much VRAM you really need
Enough VRAM means fewer stutters and texture pop-in at your settings — not the biggest number on the spec sheet.
Why VRAM matters
Video memory holds frame buffers, textures, meshes, and RT acceleration structures. When you exceed available VRAM, the driver spills to system RAM — that shows up as hitching and massive frame-time spikes, not a gentle FPS drop.
Rule-of-thumb tiers (gaming)
1080p medium/high often runs comfortably on 8 GB for many titles, but new AAA games with ultra textures and RT push toward 10–12 GB. 1440p high/ultra and path-traced workloads are safer with 12–16 GB. 4K with max settings and RT frequently benefits from 16 GB or more on the heaviest titles.
Content creation and AI
Video editing, 3D, and local AI workloads can consume VRAM independently of gaming. Size memory for your actual project resolutions and batch sizes, not only games.
