GeForce GTX 1660 vs ATI Radeon HD 3870 X2

GTX 1660 has the higher overall gaming score, while GTX 1660 offers the better price-to-performance ratio. The final choice depends on resolution and settings.

GTX 1660 is the stronger streaming choice thanks to performance, hardware encoding, and application support. Check AV1, H.264, and HEVC support before buying.

GTX 1660 is generally the better option for Blender and GPU rendering. Rendering-engine support and available VRAM also matter.

GTX 1660 offers more overall performance, while GTX 1660 offers more memory headroom. Codecs, hardware encoders, and editor optimization can change the result.

GTX 1660 is the more practical option for local AI workloads. VRAM capacity, compute libraries, and framework compatibility are especially important.

GTX 1660 is the most rational 1080p choice, where high frame rates and cost per frame matter most.

GTX 1660 leads in combined 1440p performance. GTX 1660 can be preferable for heavy textures and games with high VRAM usage.

GTX 1660 is preferable for 4K, where total performance, memory bandwidth, and VRAM capacity have the greatest impact.

GTX 1660 is easier to use in a quiet build because of its lower estimated power and thermal load. Actual noise depends on the specific cooler.

GTX 1660 is the safer candidate because its stated power consumption is lower. Verify PSU wattage, age, and power connectors.

Consider upgrading to GTX 1660 if your current device no longer delivers the required FPS, memory capacity, or feature support. A gain below 15–20% is usually worth waiting for a price cut.
