GeForce RTX 2080 SUPER vs GeForce GTX 1660 SUPER: In-Depth Breakdown
Performance: GeForce RTX 2080 SUPER vs GeForce GTX 1660 SUPER
The GeForce RTX 2080 SUPER is dramatically faster, around 91% ahead of the GeForce GTX 1660 SUPER. That gap is enough to move it up a tier: the GeForce RTX 2080 SUPER is comfortable at 1080p, while the GeForce GTX 1660 SUPER 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 SUPER.
Power & Efficiency
At 125W against 250W, the GeForce GTX 1660 SUPER is both the lower-power and the more efficient card, making it the easier build to cool and power.
VRAM & Future-Proofing
The GeForce RTX 2080 SUPER carries 8GB versus 6GB on the GeForce GTX 1660 SUPER. 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 336 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 SUPER or GeForce RTX 2080 SUPER?
The GeForce RTX 2080 SUPER is the faster card by about 91%. 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.
