GeForce RTX 2080 vs GeForce GTX 1080: In-Depth Breakdown
Performance: GeForce RTX 2080 vs GeForce GTX 1080
The GeForce RTX 2080 is dramatically faster, around 46% ahead of the GeForce GTX 1080. That gap is enough to move it up a tier: the GeForce RTX 2080 is comfortable at 1080p, while the GeForce GTX 1080 is better matched to entry-level 1080p. The GeForce RTX 2080 packs 2,944 CUDA cores versus 2,560 on the GeForce GTX 1080.
Power & Efficiency
At 180W vs 225W, the GeForce GTX 1080 is the gentler load on your system. The GeForce RTX 2080's extra power draw buys more performance per watt, not just more heat — worth it if your PSU has the headroom. Its more modern Turing architecture on a TSMC 12nm process is part of why it does more with each watt.
Memory & Bandwidth
The GeForce RTX 2080's memory is faster — 448 GB/s versus 320 GB/s — which helps feed the GPU at 4K and with heavy textures.
Generation & Longevity
The GeForce RTX 2080 is roughly 2 years newer than the GeForce GTX 1080 (Turing vs Pascal), so it generally benefits from a more modern architecture and longer driver-support runway.
Which should you buy: GeForce GTX 1080 or GeForce RTX 2080?
The GeForce RTX 2080 is the faster card by about 46%. With live pricing limited for this pair, base your decision on the spec differences above — particularly VRAM and power draw — and check current stock before buying.
