Radeon RX 6900 XT vs GeForce GTX 1660: In-Depth Breakdown
Performance: Radeon RX 6900 XT vs GeForce GTX 1660
The Radeon RX 6900 XT is dramatically faster, around 300% ahead of the GeForce GTX 1660. That gap is enough to move it up a tier: the Radeon RX 6900 XT is comfortable at 1440p, while the GeForce GTX 1660 is better matched to entry-level 1080p.
Price & Value
The GeForce GTX 1660 currently lists from $427 EUR, $185 EUR less than the Radeon RX 6900 XT at $612 EUR. Because it's both faster and competitively priced, the Radeon RX 6900 XT wins on performance-per-dollar by about 179%. The GeForce GTX 1660 still sits about $208 EUR above its $219 EUR MSRP. The Radeon RX 6900 XT is trading below its $999 EUR MSRP — a genuine deal.
Power & Efficiency
On power, the GeForce GTX 1660 is the gentler choice at 120W 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. 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 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 or Radeon RX 6900 XT?
The Radeon RX 6900 XT 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 if you find it at a steep discount.
