Frequently asked comparison questions
Short recommendations based on performance, memory, power consumption, and intended use.
01Which is better for gaming: RX 7400 or ATI Radeon HD 3870 X2?+
RX 7400 has the higher overall gaming score, while ATI Radeon HD 3870 X2 offers the better price-to-performance ratio. The final choice depends on resolution and settings.
02Which is better for streaming?+
RX 7400 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?+
RX 7400 is generally the better option for Blender and GPU rendering. Rendering-engine support and available VRAM also matter.
04Which is better for video editing?+
RX 7400 offers more overall performance, while RX 7400 offers more memory headroom. Codecs, hardware encoders, and editor optimization can change the result.
05Which is better for neural networks and AI?+
RX 7400 is the more practical option for local AI workloads. VRAM capacity, compute libraries, and framework compatibility are especially important.
06Which is better for 1080p?+
ATI Radeon HD 3870 X2 is the most rational 1080p choice, where high frame rates and cost per frame matter most.
07Which is better for 1440p?+
RX 7400 leads in combined 1440p performance. RX 7400 can be preferable for heavy textures and games with high VRAM usage.
08Which is better for 4K?+
RX 7400 is preferable for 4K, where total performance, memory bandwidth, and VRAM capacity have the greatest impact.
09Which is better for a quiet PC?+
RX 7400 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 7400 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 RX 7400 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.
