Frequently asked comparison questions
Short recommendations based on performance, memory, power consumption, and intended use.
01Which is better for gaming: RX 6800 XT or ATI Radeon HD 3870?+
RX 6800 XT has the higher overall gaming score, while RX 6800 XT offers the better price-to-performance ratio. The final choice depends on resolution and settings.
02Which is better for streaming?+
RX 6800 XT 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 6800 XT 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 6800 XT offers more overall performance, while RX 6800 XT offers more memory headroom. Codecs, hardware encoders, and editor optimization can change the result.
05Which is better for neural networks and AI?+
RX 6800 XT is the more practical option for local AI workloads. VRAM capacity, compute libraries, and framework compatibility are especially important.
06Which is better for 1080p?+
RX 6800 XT is the most rational 1080p choice, where high frame rates and cost per frame matter most.
07Which is better for 1440p?+
RX 6800 XT leads in combined 1440p performance. RX 6800 XT can be preferable for heavy textures and games with high VRAM usage.
08Which is better for 4K?+
RX 6800 XT is preferable for 4K, where total performance, memory bandwidth, and VRAM capacity have the greatest impact.
09Which is better for a quiet PC?+
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.
10Which is better without replacing the power supply?+
ATI Radeon HD 3870 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 6800 XT 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.
