| Category | Winner | Why |
|---|---|---|
| CPU Performance | Raspberry Pi 5 (4GB) | The Pi 5's Cortex-A76 at 2.4GHz is roughly 3x faster than the CB2's Cortex-A55 at 1.8GHz and 4x faster than the CB1's Cortex-A53 at 1.5GHz. For Klipper alone this is overkill, but it matters for running multiple services (webcam, OctoPrint, timelapse rendering). |
| Manta M8P Integration | BIGTREETECH CB2 | Both the CB1 and CB2 plug directly into the Manta M8P's BTB socket — no USB cable, no separate power supply, no additional mounting. The Pi 5 connects via USB and needs its own 27W power supply and mounting location. |
| RAM and Storage | Raspberry Pi 5 (4GB) | The Pi 5 has 4GB LPDDR4X RAM and supports NVMe SSDs via PCIe. The CB2 has 2GB RAM and 16GB eMMC. The CB1 has just 1GB RAM and MicroSD only. For Klipper, 1GB is adequate but 2GB provides more headroom for plugins and logging. |
| Network Connectivity | BIGTREETECH CB2 | The CB2 has Gigabit Ethernet and WiFi 802.11ac. The CB1 has 100M Ethernet only (via USB adapter). The Pi 5 also has Gigabit Ethernet but costs significantly more. For reliable Klipper communication, Gigabit Ethernet on the CB2 at $45 is the sweet spot. |
| Price | BIGTREETECH CB1 | The CB1 at $35 is the cheapest viable Klipper host. The CB2 at $45 adds meaningful upgrades for $10 more. The Pi 5 at $60 (board only) plus $15 power supply plus mounting hardware totals $80-100 — 2x the CB2 price. |
