For a VPX payload, how do the VPX3-1711 and Graphite VPX compare on PCIe generation, onboard storage and FP32 TFLOPS?

Question

Rapidflare · Accepted Answer

Here's how the two 3U VPX payload blades compare on those three dimensions:

## VPX3-1711 vs. Graphite VPX

| Attribute | VPX3-1711 (Curtiss-Wright) | Graphite VPX (Connect Tech) |
|-----------|---------------------------|---------------------------|
| PCIe generation | Gen3 (PCIe Gen3 x8) | Gen4 |
| Onboard storage | 1 TB NVMe | 64 GB |
| FP32 TFLOPS | 4.8 TFLOPS | 4.8 TFLOPS |

## Key differences

- **PCIe generation:** The Graphite VPX supports PCIe Gen4 , a generation ahead of the VPX3-1711's Gen3 x8 interface .
- **Onboard storage:** The VPX3-1711 ships with 1 TB of onboard NVMe storage , substantially more than the Graphite VPX's 64 GB .
- **FP32 TFLOPS:** Both are equal at 4.8 TFLOPS — expected, since both blades are built on the same Jetson AGX Orin Industrial SoM.

In short: choose the Graphite VPX if higher PCIe generation matters for backplane throughput; choose the VPX3-1711 if large onboard storage capacity is the priority. Compute performance is a wash.
