Frequently asked comparison questions
Short recommendations based on performance, memory, power consumption, and intended use.
01Which is better for gaming: Arc B770 or RX 6400?+
Arc B770 has the higher overall gaming score, while Arc B770 offers the better price-to-performance ratio. The final choice depends on resolution and settings.
02Which is better for streaming?+
Arc B770 is the stronger streaming choice thanks to performance, hardware encoding, and application support. Check AV1, H.264, and HEVC support before buying.
03Which is better for Blender?+
Arc B770 is generally the better option for Blender and GPU rendering. Rendering-engine support and available VRAM also matter.
04Which is better for video editing?+
Arc B770 offers more overall performance, while Arc B770 offers more memory headroom. Codecs, hardware encoders, and editor optimization can change the result.
05Which is better for neural networks and AI?+
Arc B770 is the more practical option for local AI workloads. VRAM capacity, compute libraries, and framework compatibility are especially important.
06Which is better for 1080p?+
Arc B770 is the most rational 1080p choice, where high frame rates and cost per frame matter most.
07Which is better for 1440p?+
Arc B770 leads in combined 1440p performance. Arc B770 can be preferable for heavy textures and games with high VRAM usage.
08Which is better for 4K?+
Arc B770 is preferable for 4K, where total performance, memory bandwidth, and VRAM capacity have the greatest impact.
09Which is better for a quiet PC?+
RX 6400 is easier to use in a quiet build because of its lower estimated power and thermal load. Actual noise depends on the specific cooler.
10Which is better without replacing the power supply?+
RX 6400 is the safer candidate because its stated power consumption is lower. Verify PSU wattage, age, and power connectors.
11Is it worth upgrading from the previous generation?+
Consider upgrading to Arc B770 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.
