Fields

vendor: GpuVendor

name: String

index: u32

generation: String

Architecture / generation label, e.g. “Blackwell” (RTX 5060), “Ada Lovelace” (RTX 4000-series), “Ampere” (RTX 3000), “Alchemist DG2” (Arc A-series), “Battlemage BMG” (Arc B-series), “RDNA3” (RX 7000). Phase 2 (2026-05-07) inventory page surface — derived from the PCI device id at detect time so the inventory aggregations don’t have to re-derive it. “Unknown” when the device id falls outside the per-vendor known-id table; preserved verbatim to the admin UI so operators can spot fleet rows that need a label update.

pci_id: String

Lowercase vendor:device PCI tuple, e.g. "0x10de:0x2d05". Stable identifier across driver / kernel versions. Empty string when the platform path doesn’t expose a device id (NVIDIA via CUDA on Windows: cuda doesn’t surface PCI; the field stays empty rather than synthesise something misleading).

vram_mib: u64

Total VRAM in MiB. NVIDIA via NVML memory_info().total; Intel via /sys/class/drm/cardN/device/mem_info_vram_total when present; AMD same. 0 when the platform path can’t read it — admin UI shows “—” for that case rather than “0 MiB”.

serial: Option<String>

Vendor-reported serial number of the physical card. NVIDIA via NVML Device::serial() (returns the manufacturer’s serial sticker for cards that have one — datacenter Tesla / A10G / consumer Pro cards expose it; consumer GeForce typically doesn’t). Intel / AMD: try /sys/class/drm/cardN/device/serial[_number] paths; usually None. Stable identifier for warranty tracking + the transcoder_gpus asset table — when present, the same card across host moves dedups to a single row.

host_pci_address: String

PCI host slot address, e.g. "04:00.0". Used as the dedupe fallback when serial is absent — assumes the card stays in the same slot of the same host (the dev-box reality). Empty when the platform path doesn’t expose it.

vendor_id_hex: String

Vendor portion of the PCI tuple as a standalone hex string, e.g. "0x10de". Already implicit in pci_id but exposed separately so the SQL inventory query can index on it without parsing.
