Here's the comparison for the two 1U AGX Orin rackmount systems:
| RTSS-Z1021U (Realtimes, Feiyun Smart Box) | T919 (Twowin T-Series) | |
|---|---|---|
| Ethernet ports | 3× GbE (max speed 1GbE) | 2 ports total, max speed 10GbE |
| Weight | 5,300 g (5.3 kg) | 3,000 g (3 kg) |
| Power input | 100~240V AC | 100–240V AC wide input, 1 A, built-in power supply |
Summary of the differences:
- Ethernet: The RTSS-Z1021U has more ports (3 vs 2), but the T919's ports support up to 10GbE — significantly higher per-port bandwidth than the RTSS-Z1021U's 1GbE, which matters if you need high-throughput networking for large data transfers or multi-camera streams.
- Weight: The T919 is notably lighter at 3 kg vs the RTSS-Z1021U's 5.3 kg — relevant for shipping, handling, and rack-loading if you're deploying multiple units.
- Power input: Both accept standard 100–240V AC mains, so neither requires special DC power infrastructure. The T919 additionally lists a 70 W max power consumption figure with a built-in PSU.
Both support AGX Orin (RTSS-Z1021U also supports AGX Xavier 32GB modules), and both are 1U rackmount form factors with comparable onboard storage (64 GB).
