Verified Confidence: 85%

Verdict: The RTX 4090 still holds the crown for sheer raw performance, delivering about 12% higher raster scores than the RTX 5080 (Tom's Hardware). However, the RTX 5080 narrows the gap with a 22% better performance‑per‑watt ratio, adds DLSS 3.5, and runs 100 W cooler, making it a more efficient choice for builders with power or thermal constraints (AnandTech, Nvidia). For users who need absolute maximum power or large VRAM for 8K workloads, the RTX 4090 remains the top pick, but most high‑end gamers will find the RTX 5080 offers comparable performance with lower system demands.

Winner: NVIDIA GeForce RTX 4090

NVIDIA GeForce RTX 4090: 8.5/10
