About MCMark
What is MCMark?
MCMark is a free, open-source benchmark mod for Minecraft Java Edition (Fabric 1.21.11). It measures your PC's performance in standardized Minecraft scenarios and produces a deterministic score you can compare with others worldwide.
Benchmark Types
| LOW | Lightest CPU + tower tier for weak PCs: reduced AI camp/chase load, reduced tower FX, and lighter particle and sandball pressure. |
| NORMAL | Standard CPU + tower tier with the former HARD-level CPU load and full tower flythrough FX. |
| EXTREME | Heaviest CPU + tower tier for maximum stress and the full tower flythrough. |
| GPU | Shader-powered disco room with colored lighting |
| RAM | Memory allocation + entity simulation |
| DISK | Synthetic I/O throughput (4 phases) |
| CHUNKY | Chunk generation speed |
Profiles
| Profile | Used For | Render Distance | Graphics |
|---|---|---|---|
| LOW | All non-GPU presets | 8 | Fast |
| HIGH | GPU preset | 16 | Fancy |
| ULTRA | GPU preset | 24 | Fabulous |

Privacy
When you submit a score, MCMark sends your Minecraft username, UUID, benchmark metrics, and technical environment data needed to validate leaderboard runs. Public pages show a reduced hardware summary, score metrics, and benchmark metadata - not the full raw validation payload. Cloudflare also processes service-side network metadata as infrastructure provider.
