GeForce RTX 3080 12GB vs GeForce GTX 1080: In-Depth Breakdown
Performance: GeForce RTX 3080 12GB vs GeForce GTX 1080
The GeForce RTX 3080 12GB is dramatically faster, around 185% ahead of the GeForce GTX 1080. That gap is enough to move it up a tier: the GeForce RTX 3080 12GB is comfortable at 1440p, while the GeForce GTX 1080 is better matched to entry-level 1080p. The GeForce RTX 3080 12GB packs 8,960 CUDA cores versus 2,560 on the GeForce GTX 1080.
Power & Efficiency
On power, the GeForce GTX 1080 is the gentler choice at 180W versus 350W. The GeForce RTX 3080 12GB is more efficient per watt because it's faster, but its higher 350W draw means more heat and a bigger PSU. Its more modern Ampere architecture on a Samsung 8nm process is part of why it does more with each watt.
VRAM & Future-Proofing
VRAM favors the GeForce RTX 3080 12GB at 12GB versus 8GB on the GeForce GTX 1080 — that extra 4GB matters most at 4K, with high-res texture packs, and for content-creation/local-AI work. The GeForce RTX 3080 12GB's memory is also faster — 912 GB/s versus 320 GB/s (384-bit vs 256-bit bus) — which helps feed the GPU at 4K and with heavy textures.
Generation & Longevity
The GeForce RTX 3080 12GB is roughly 6 years newer than the GeForce GTX 1080 (Ampere vs Pascal), so it generally benefits from a more modern architecture and longer driver-support runway.
