Native 4K at 60+ fps in current AAA titles needs ~16 GB of VRAM, a 256-bit or wider memory bus, and ray-tracing hardware at least on Blackwell / RDNA 4 level. 8 GB cards can't hold full-res texture pools anymore.

DLSS 4 vs FSR 4

DLSS 4 with Multi-Frame Generation is the reason the RTX 5070 Ti can stand in for a 5090 in many games at 4K. FSR 4 closes the gap but still trails in motion clarity.

Flagship tier

RTX 5090 and 5090 Super are overkill for anything but 4K at max settings with full path tracing. RX 9080 XT competes at raster 4K but lags in RT.

Sweet spot (most people buy this)

RTX 5070 Ti or RTX 5080 with DLSS 4 Quality delivers 4K/60 comfortably in every 2026 AAA title.
