GeForce GTX 1660 SUPER vs Radeon RX 590: In-Depth Breakdown
Performance: GeForce GTX 1660 SUPER vs Radeon RX 590
The GeForce GTX 1660 SUPER is dramatically faster, around 57% ahead of the Radeon RX 590. Both cards sit in the same broad class, well suited to entry-level 1080p.
Power & Efficiency
At 125W against 225W, the GeForce GTX 1660 SUPER is both the lower-power and the more efficient card, making it the easier build to cool and power. Its more modern Turing architecture on a TSMC 12nm process is part of why it does more with each watt.
VRAM & Future-Proofing
The Radeon RX 590 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.
Features & Ecosystem
Beyond raw numbers, the GeForce GTX 1660 SUPER brings NVIDIA DLSS upscaling/frame generation and stronger ray tracing, while the Radeon RX 590 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 590?
The GeForce GTX 1660 SUPER is the faster card by about 57%. 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.
