Radeon RX 6900 XT vs ATI Radeon HD 3690

RX 6900 XT has the higher overall gaming score, while ATI Radeon HD 3690 offers the better price-to-performance ratio. The final choice depends on resolution and settings.

RX 6900 XT is the stronger streaming choice thanks to performance, hardware encoding, and application support. Check AV1, H.264, and HEVC support before buying.

RX 6900 XT is generally the better option for Blender and GPU rendering. Rendering-engine support and available VRAM also matter.

RX 6900 XT offers more overall performance, while RX 6900 XT offers more memory headroom. Codecs, hardware encoders, and editor optimization can change the result.

RX 6900 XT is the more practical option for local AI workloads. VRAM capacity, compute libraries, and framework compatibility are especially important.

ATI Radeon HD 3690 is the most rational 1080p choice, where high frame rates and cost per frame matter most.

RX 6900 XT leads in combined 1440p performance. RX 6900 XT can be preferable for heavy textures and games with high VRAM usage.

RX 6900 XT is preferable for 4K, where total performance, memory bandwidth, and VRAM capacity have the greatest impact.

ATI Radeon HD 3690 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 3690 is the safer candidate because its stated power consumption is lower. Verify PSU wattage, age, and power connectors.

Consider upgrading to RX 6900 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.
