Pros & cons
- Among the strongest GPUs in this catalog
- Generous 24GB VRAM — comfortable headroom for high-res textures and modding
- Supports upscaling (DLSS, DLSS-FG) for extra headroom at higher resolutions
- Strong ray tracing capability for this generation
- High power draw (450W) — needs a capable PSU and case airflow
Frequently asked questions
It depends entirely on the game, resolution, settings and the CPU it's paired with — there is no single answer. Use the calculator above to get an estimate for your exact combination, or see the sample results table for a few reference points.
Based on its relative performance index (99/100), we'd suggest 4K as the most comfortable target for this GPU at High/Ultra settings.
Yes — its ray tracing support tier is rated 'top' in our catalog, meaning a moderate to significant frame rate cost when RT is enabled, partly offset by upscaling if supported.
For a balanced build, CPUs like AMD Ryzen 9 7950X3D, AMD Ryzen 7 9800X3D tend to match this GPU's performance tier well — see the recommended CPUs panel for links.
