Radeon RX 6600 vs GeForce GTX 1660 SUPER: In-Depth Breakdown

Performance: Radeon RX 6600 vs GeForce GTX 1660 SUPER

The Radeon RX 6600 is significantly faster, around 36% ahead of the GeForce GTX 1660 SUPER. That gap is enough to move it up a tier: the Radeon RX 6600 is comfortable at 1080p, while the GeForce GTX 1660 SUPER is better matched to entry-level 1080p.

Price & Value

The GeForce GTX 1660 SUPER currently lists from $318 EUR, $118 EUR less than the Radeon RX 6600 at $436 EUR. Despite being slower, the GeForce GTX 1660 SUPER offers the better performance-per-dollar, so budget-focused buyers should weigh it carefully. The GeForce GTX 1660 SUPER still sits about $89 EUR above its $229 EUR MSRP. The Radeon RX 6600 still sits about $106 EUR above its $330 EUR MSRP.

Power & Efficiency

On power, the GeForce GTX 1660 SUPER is the gentler choice at 125W versus 132W. The Radeon RX 6600 is more efficient per watt because it's faster, but its higher 132W 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 6600 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.

Generation & Longevity

The Radeon RX 6600 is roughly 2 years newer than the GeForce GTX 1660 SUPER (RDNA 2 vs Turing), so it generally benefits from a more modern architecture and longer driver-support runway.

Features & Ecosystem

Beyond raw numbers, the GeForce GTX 1660 SUPER brings NVIDIA DLSS upscaling/frame generation and stronger ray tracing, while the Radeon RX 6600 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 6600?

Choose the Radeon RX 6600 if you want the most performance and can absorb the higher price. If you're optimizing for value, the GeForce GTX 1660 SUPER stretches your money further for only slightly lower performance.

Frequently Asked Questions

Is the Radeon RX 6600 better than the GeForce GTX 1660 SUPER?

The Radeon RX 6600 is significantly faster, roughly 36% ahead. The GeForce GTX 1660 SUPER is still worth it if value matters more than top-end frames.

Which is better for 4K gaming, the GeForce GTX 1660 SUPER or the Radeon RX 6600?

Neither is a dedicated 4K card; both are best at 1080p. For 4K you'd want a faster GPU, or lean on upscaling.

Is the Radeon RX 6600 worth the extra $118 EUR over the GeForce GTX 1660 SUPER?

Only if you need the extra performance or features; on pure value the GeForce GTX 1660 SUPER comes out ahead.

Does the Radeon RX 6600 have enough VRAM advantage to matter?

Its 8GB (vs 6GB) gives real headroom for 4K, heavy texture mods, and creative/AI work. At 1080p the gap matters less.
