Intel Arc B570 vs ATI Radeon HD 3870

Arc B570 has the higher overall gaming score, while Arc B570 offers the better price-to-performance ratio. The final choice depends on resolution and settings.

Arc B570 is the stronger streaming choice thanks to performance, hardware encoding, and application support. Check AV1, H.264, and HEVC support before buying.

Arc B570 is generally the better option for Blender and GPU rendering. Rendering-engine support and available VRAM also matter.

Arc B570 offers more overall performance, while Arc B570 offers more memory headroom. Codecs, hardware encoders, and editor optimization can change the result.

Arc B570 is the more practical option for local AI workloads. VRAM capacity, compute libraries, and framework compatibility are especially important.

Arc B570 is the most rational 1080p choice, where high frame rates and cost per frame matter most.

Arc B570 leads in combined 1440p performance. Arc B570 can be preferable for heavy textures and games with high VRAM usage.

Arc B570 is preferable for 4K, where total performance, memory bandwidth, and VRAM capacity have the greatest impact.

ATI Radeon HD 3870 is easier to use in a quiet build because of its lower estimated power and thermal load. Actual noise depends on the specific cooler.

ATI Radeon HD 3870 is the safer candidate because its stated power consumption is lower. Verify PSU wattage, age, and power connectors.

Consider upgrading to Arc B570 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.
