Kabel USB-C bisa berupa USB 2.0 (480 Mbps) atau Thunderbolt 5 (120 Gbps). Begini cara membedakannya.
## The Myth
All USB-C cables look identical, so they must all work the same way.
## The Reality
USB-C cables vary enormously:
| Cable Type | Speed | Power | Video | Price |
|---|---|---|---|---|
| USB-C 2.0 | 480 Mbps | 60W | No | $5 |
| USB-C 3.2 Gen 1 | 5 Gbps | 60W | Maybe | $10 |
| USB-C 3.2 Gen 2 | 10 Gbps | 100W | DP Alt | $15 |
| Thunderbolt 3 | 40 Gbps | 100W | 2× 4K | $30 |
| Thunderbolt 4 | 40 Gbps | 100W | 2× 4K | $40 |
| USB4 v2.0 | 80 Gbps | 240W | 3× 4K | $50+ |
| Thunderbolt 5 | 120 Gbps | 240W | 3× 4K | $70+ |
## How to Tell Them Apart
- **Check the packaging** for speed rating
- **Look for icons** on the cable or connector (⚡ = Thunderbolt, SS = SuperSpeed)
- **Check the price** — if it's suspiciously cheap, it's probably USB 2.0
- **Feel the cable** — thicker cables usually carry more wires for higher speeds
## Why It Matters
Using a USB 2.0 cable with a Thunderbolt dock means no video output, no fast data, and possibly no charging. The cable looks identical but functions completely differently.
