GeForce RTX 2080 SUPER vs GeForce GTX 1660: In-Depth Breakdown
Performance: GeForce RTX 2080 SUPER vs GeForce GTX 1660
The GeForce RTX 2080 SUPER is dramatically faster, around 127% ahead of the GeForce GTX 1660. That gap is enough to move it up a tier: the GeForce RTX 2080 SUPER is comfortable at 1080p, while the GeForce GTX 1660 is better matched to entry-level 1080p. The GeForce RTX 2080 SUPER packs 3,072 CUDA cores versus 1,408 on the GeForce GTX 1660.
Power & Efficiency
On power, the GeForce GTX 1660 is the gentler choice at 120W versus 250W. The GeForce RTX 2080 SUPER is more efficient per watt because it's faster, but its higher 250W draw means more heat and a bigger PSU.
VRAM & Future-Proofing
The GeForce RTX 2080 SUPER carries 8GB versus 6GB on the GeForce GTX 1660. The extra 2GB helps at 4K, with high-resolution texture packs, and for content-creation or local-AI workloads that exhaust smaller buffers. The GeForce RTX 2080 SUPER's memory is also faster — 496 GB/s versus 192 GB/s (256-bit vs 192-bit bus) — which helps feed the GPU at 4K and with heavy textures.
Which should you buy: GeForce GTX 1660 or GeForce RTX 2080 SUPER?
The GeForce RTX 2080 SUPER is the faster card by about 127%. 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.
