GeForce RTX 4070 SUPER vs GeForce RTX 3080 12GB: In-Depth Breakdown
Performance: GeForce RTX 4070 SUPER vs GeForce RTX 3080 12GB
The GeForce RTX 4070 SUPER is noticeably faster, around 16% ahead of the GeForce RTX 3080 12GB. That gap is enough to move it up a tier: the GeForce RTX 4070 SUPER is comfortable at 4K with upscaling and native 1440p, while the GeForce RTX 3080 12GB is better matched to 1440p.
Power & Efficiency
The GeForce RTX 4070 SUPER sips power at 220W next to the GeForce RTX 3080 12GB's 350W, and still leads on performance-per-watt — quieter, cooler, and gentler on your PSU. Its more modern Ada Lovelace architecture on a TSMC N4 process is part of why it does more with each watt.
Memory & Bandwidth
The GeForce RTX 3080 12GB's memory is faster — 912 GB/s versus 504 GB/s (384-bit vs 192-bit bus) — which helps feed the GPU at 4K and with heavy textures.
Generation & Longevity
The GeForce RTX 4070 SUPER is roughly 2 years newer than the GeForce RTX 3080 12GB (Ada Lovelace vs Ampere), so it generally benefits from a more modern architecture and longer driver-support runway.
