Radeon RX 6900 XT vs GeForce GTX 1660 SUPER: In-Depth Breakdown
Performance: Radeon RX 6900 XT vs GeForce GTX 1660 SUPER
The Radeon RX 6900 XT is dramatically faster, around 264% ahead of the GeForce GTX 1660 SUPER. That gap is enough to move it up a tier: the Radeon RX 6900 XT is comfortable at 1440p, while the GeForce GTX 1660 SUPER is better matched to entry-level 1080p.
Power & Efficiency
On power, the GeForce GTX 1660 SUPER is the gentler choice at 125W versus 300W. The Radeon RX 6900 XT is more efficient per watt because it's faster, but its higher 300W draw means more heat and a bigger PSU. Its more modern RDNA 2 architecture on a TSMC N7 process is part of why it does more with each watt.
VRAM & Future-Proofing
The Radeon RX 6900 XT carries 16GB versus 6GB on the GeForce GTX 1660 SUPER. The extra 10GB helps at 4K, with high-resolution texture packs, and for content-creation or local-AI workloads that exhaust smaller buffers.
Features & Ecosystem
Beyond raw numbers, the GeForce GTX 1660 SUPER brings NVIDIA DLSS upscaling/frame generation and stronger ray tracing, while the Radeon RX 6900 XT offers AMD FSR upscaling and strong rasterization value. If you lean on upscaling or ray tracing, that ecosystem difference can matter as much as the frame-rate gap.
Which should you buy: GeForce GTX 1660 SUPER or Radeon RX 6900 XT?
The Radeon RX 6900 XT is the faster card by about 264%. 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.
