GeForce RTX 4090 vs GeForce RTX 3080 Ti: In-Depth Breakdown
Performance: GeForce RTX 4090 vs GeForce RTX 3080 Ti
The GeForce RTX 4090 is dramatically faster, around 85% ahead of the GeForce RTX 3080 Ti. That gap is enough to move it up a tier: the GeForce RTX 4090 is comfortable at 4K and high-refresh 1440p, while the GeForce RTX 3080 Ti is better matched to 1440p. The GeForce RTX 4090 packs 16,384 CUDA cores versus 10,240 on the GeForce RTX 3080 Ti.
Price & Value
The GeForce RTX 4090 currently lists from $504 SEK, $8,443 SEK less than the GeForce RTX 3080 Ti at $8,948 SEK. Because it's both faster and competitively priced, the GeForce RTX 4090 wins on performance-per-dollar by about 3176%. The GeForce RTX 4090 is trading below its $1,599 SEK MSRP — a genuine deal. The GeForce RTX 3080 Ti still sits about $7,749 SEK above its $1,199 SEK MSRP.
Power & Efficiency
On power, the GeForce RTX 3080 Ti is the gentler choice at 350W versus 450W. The GeForce RTX 4090 is more efficient per watt because it's faster, but its higher 450W draw means more heat and a bigger PSU. Its more modern Ada Lovelace architecture on a TSMC 4N process is part of why it does more with each watt.
VRAM & Future-Proofing
The GeForce RTX 4090 carries 24GB versus 12GB on the GeForce RTX 3080 Ti. The extra 12GB helps at 4K, with high-resolution texture packs, and for content-creation or local-AI workloads that exhaust smaller buffers. The GeForce RTX 4090's memory is also faster — 1,008 GB/s versus 912 GB/s — which helps feed the GPU at 4K and with heavy textures.
Which should you buy: GeForce RTX 3080 Ti or GeForce RTX 4090?
The GeForce RTX 4090 is the all-round winner here — it's faster and the better value, so buy it if it fits your budget. Only consider the GeForce RTX 3080 Ti if you find it at a steep discount.
