GPU PCIe Diagnostic & Bandwidth Analysis
A deterministic command-line tool for validating GPU PCIe link health, bandwidth, and real-world PCIe utilization using only observable hardware data.
This tool answers one question reliably:
Is my GPU’s PCIe link behaving as it should, and can I prove it?
No registry hacks. No BIOS assumptions. No “magic” optimizations.
Only measurable link state, copy throughput, and hardware counters.
What This Tool Does
This tool performs hardware-observable PCIe diagnostics and reports factual results with deterministic verdicts.
It measures and reports directly from GPU hardware:
PCIe current and maximum link generation and width (via NVML)
