GeForce RTX 3090 vs GeForce GTX 1660 Ti: In-Depth Breakdown
Performance: GeForce RTX 3090 vs GeForce GTX 1660 Ti
The GeForce RTX 3090 is dramatically faster, around 255% ahead of the GeForce GTX 1660 Ti. That gap is enough to move it up a tier: the GeForce RTX 3090 is comfortable at 1440p, while the GeForce GTX 1660 Ti is better matched to entry-level 1080p. The GeForce RTX 3090 packs 10,496 CUDA cores versus 1,536 on the GeForce GTX 1660 Ti.
Price & Value
The GeForce GTX 1660 Ti currently lists from $7,064 SEK, $8,478 SEK less than the GeForce RTX 3090 at $15,542 SEK. Because it's both faster and competitively priced, the GeForce RTX 3090 wins on performance-per-dollar by about 61%. The GeForce GTX 1660 Ti still sits about $6,785 SEK above its $279 SEK MSRP. The GeForce RTX 3090 still sits about $14,043 SEK above its $1,499 SEK MSRP.
Power & Efficiency
On power, the GeForce GTX 1660 Ti is the gentler choice at 120W versus 350W. The GeForce RTX 3090 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
The GeForce RTX 3090 carries 24GB versus 6GB on the GeForce GTX 1660 Ti. The extra 18GB helps at 4K, with high-resolution texture packs, and for content-creation or local-AI workloads that exhaust smaller buffers. The GeForce RTX 3090's memory is also faster — 936 GB/s versus 288 GB/s (384-bit vs 192-bit bus) — which helps feed the GPU at 4K and with heavy textures.
Which should you buy: GeForce GTX 1660 Ti or GeForce RTX 3090?
The GeForce RTX 3090 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 GTX 1660 Ti if you find it at a steep discount.
