Both are IGX T7000-based edge AI servers, and on the three dimensions you asked about they match closely — here's the breakdown.
PCIe generation: Both systems support PCIe Gen5. Serial ports: Both provide 4 serial ports. advantech... +1advantech.com ↗“io.serial_port_count=4”yuan.com.tw ↗“io.serial_port_count=4” advantech... +1advantech.com ↗“io.pcie_max_gen=5”yuan.com.tw ↗“io.pcie_max_gen=5”
SFP/QSFP ports: Both list 2 SFP-family ports. The difference is speed:
- AIR-427A (Advantech): two 200GbE QSFP28 ports. advantech...advantech.com ↗“Two 200GbE QSFP28 ports”
- NEAR T7X (YUAN High-Tech): 2x 100Gb QSFP112. Side-by-side advantech... +1advantech.com ↗“Advantech IGX Thor T7000 edge AI server”yuan.com.tw ↗“Edge AI workstation/server with NVIDIA IGX Thor” yuan.com.twyuan.com.tw ↗“2x 100Gb QSFP112”
| Attribute | AIR-427A (Advantech) | NEAR T7X (YUAN High-Tech) |
|---|---|---|
| PCIe max generation | Gen5 | Gen5 |
| Serial ports | 4 | 4 |
| SFP/QSFP ports | 2 (200GbE QSFP28) | 2 (100Gb QSFP112) |
| PCIe slots | 2 | 1 |
| Ethernet (RJ45) | 2x 1GbE | 2x GbE |
So for your IGX Thor edge rack: PCIe generation and serial ports are identical, and the real differentiator in this comparison is the high-speed fabric — the AIR-427A doubles per-port uplink bandwidth with 200GbE QSFP28 versus the NEAR T7X's 100Gb QSFP112, while the NEAR T7X also has 1 DIO channel the AIR-427A doesn't list. advantech... +1advantech.com ↗“io.sfp_ports=2”yuan.com.tw ↗“io.dio_channel_count=1”
