PCIe-GL26 vs PCIe-NX156U3: which Jetson does each carry, what PCIe generation, and are they still active?

Question

Rapidflare · Accepted Answer

Both are Neousys PCIe frame grabber/vision accelerator cards, but they're built on different Jetson generations — and their lifecycle status differs significantly.

| | PCIe-GL26 | PCIe-NX156U3 |
|---|---|---|
| **Jetson module** | Jetson Xavier NX (8GB / 16GB) | Jetson Orin NX (8GB / 16GB) |
| **Jetson family** | Jetson Xavier NX | Jetson Orin NX |
| **PCIe generation** | PCIe Gen 3 | PCIe Gen 4 |
| **Lifecycle status** | EOL | Active |
| **AI performance** | 21 TOPS (INT8, dense) | 100 TOPS (INT8, sparse) |
| **FP32 performance** | 0.845 TFLOPS | 1.88 TFLOPS |

In short: the **PCIe-GL26** is an older card built on the Xavier NX platform, at **Gen 3**, and is now **end-of-life**. The **PCIe-NX156U3** is the newer generation built on Orin NX, at **Gen 4**, and is **still active**. Note that the performance figures aren't directly comparable across the two — the GL26's 21 TOPS is dense INT8, while the NX156U3's 100 TOPS is sparse INT8, per each manufacturer's stated basis.
