Gaming FPS
Available results are shown separately; missing data is not treated as zero.
The Gaming FPS section compares RTX 3080 and GT 630 across curated H2H Lab game presets. The useful signal is not only average FPS, but also how each device behaves at 1440p and 4K, how memory capacity and bus width affect heavy textures, and whether the game engine favors raster performance, ray tracing, or driver maturity.

Frequently asked comparison questions
Short recommendations based on performance, memory, power consumption, and intended use.
01Which is better for gaming: RTX 3080 or GT 630?+
RTX 3080 has the higher overall gaming score, while RTX 3080 offers the better price-to-performance ratio. The final choice depends on resolution and settings.
02Which is better for streaming?+
RTX 3080 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?+
RTX 3080 is generally the better option for Blender and GPU rendering. Rendering-engine support and available VRAM also matter.
04Which is better for video editing?+
RTX 3080 offers more overall performance, while RTX 3080 offers more memory headroom. Codecs, hardware encoders, and editor optimization can change the result.
05Which is better for neural networks and AI?+
RTX 3080 is the more practical option for local AI workloads. VRAM capacity, compute libraries, and framework compatibility are especially important.
06Which is better for 1080p?+
RTX 3080 is the most rational 1080p choice, where high frame rates and cost per frame matter most.
07Which is better for 1440p?+
RTX 3080 leads in combined 1440p performance. RTX 3080 can be preferable for heavy textures and games with high VRAM usage.
08Which is better for 4K?+
RTX 3080 is preferable for 4K, where total performance, memory bandwidth, and VRAM capacity have the greatest impact.
09Which is better for a quiet PC?+
GT 630 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?+
GT 630 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 RTX 3080 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.
