GeForce RTX 3080 12GB vs GeForce RTX 2080 Ti: In-Depth Breakdown
Performance: GeForce RTX 3080 12GB vs GeForce RTX 2080 Ti
The GeForce RTX 3080 12GB is dramatically faster, around 48% ahead of the GeForce RTX 2080 Ti. That gap is enough to move it up a tier: the GeForce RTX 3080 12GB is comfortable at 1440p, while the GeForce RTX 2080 Ti is better matched to 1080p. The GeForce RTX 3080 12GB packs 8,960 CUDA cores versus 4,352 on the GeForce RTX 2080 Ti.
Price & Value
The GeForce RTX 2080 Ti currently lists from $334 GBP, $736 GBP less than the GeForce RTX 3080 12GB at $1,070 GBP. Despite being slower, the GeForce RTX 2080 Ti offers the better performance-per-dollar (~116% better value), so budget-focused buyers should weigh it carefully. The GeForce RTX 2080 Ti is trading below its $999 GBP MSRP — a genuine deal. The GeForce RTX 3080 12GB still sits about $271 GBP above its $799 GBP MSRP.
Power & Efficiency
On power, the GeForce RTX 2080 Ti is the gentler choice at 250W 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 11GB on the GeForce RTX 2080 Ti — that extra 1GB 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 616 GB/s (384-bit vs 352-bit bus) — which helps feed the GPU at 4K and with heavy textures.
Generation & Longevity
The GeForce RTX 3080 12GB is roughly 4 years newer than the GeForce RTX 2080 Ti (Ampere vs Turing), so it generally benefits from a more modern architecture and longer driver-support runway.
Which should you buy: GeForce RTX 2080 Ti or GeForce RTX 3080 12GB?
Choose the GeForce RTX 3080 12GB if you want the most performance and can absorb the higher price. If you're optimizing for value, the GeForce RTX 2080 Ti stretches your money further for only slightly lower performance.
