The Forensic
Certification Standard
Every GPU submitted to Assurd Techlabs passes through five mandatory phases of forensic inspection. No shortcuts. No consumer benchmarks taken at face value. No exceptions.
Physical & Electrical Triage
Before any power is applied, we treat every submitted unit as potentially dangerous. The card is inspected under a bench lamp for PCB damage, capacitor trauma, burnt traces and connector deformation, and its PCIe fingers and power connectors under magnification. We then check the 12 V and 3.3 V inputs for shorts and measure rail-to-ground resistance with a bench multimeter: the three primary rails on every tier, all six on Premium. Shorts are caught before the card ever touches a live bench.
Any short on the 12V or 3.3V rail, any power rail reading 0.1 Ω or less to ground, a PCB graded F, broken PCIe pads, a dead fan, or a melted 12VHPWR connector triggers immediate quarantine. The unit cannot proceed.
Silicon DNA & Cryptographic Verification
We connect a hardware SPI flash reader directly to the GPU's VBIOS chip — bypassing the driver stack entirely. The server SHA-256 hashes the extracted binary and looks it up among the Assurd VBIOS Hash Registry's factory references for that board; firmware that is not in the registry is reported as such, not as a failure. We also cross-check the card's reported configuration against the registry entry for its board to catch counterfeit board substitutions.

> VERDICT: MATCHES THE REGISTRY REFERENCE
A card that GPU-Z reports as [FAKE], or a critical spec mismatch, is an immediate rejection. Firmware that is not in the registry is shown as such and is not a failure: Assurd does not yet detect modified or mining firmware.
Thermal Forensics & 1800-Second Heat Soak
Consumer benchmarks run for 90–300 seconds. Our forensic thermal trace runs for 1800 seconds — 30 minutes of continuous full load. This is not arbitrary. A GPU heatsink has a thermal time constant (τ = Rθ × Cθ), estimated at 600–1200 seconds for a triple-fan cooler. Short tests measure the transient response. We measure every card over the same window, the last five minutes of load: near equilibrium for a fast cooler, still approaching it for a slow one, and comparable across cards. A radiometric thermal image is captured in that window on every tier; Premium adds a calibrated acoustic recording.
Grades are gated by the hotspot delta, the mean of hotspot minus core temperature over 1500–1800 s of load. The thresholds are engineering priors pending fleet calibration (n ≈ 300).
Units with ΔT between 18°C and 30°C are issued a 'PASS — TIM DEGRADED' verdict. These units are capped at a BRONZE grade regardless of other performance metrics, and the certificate discloses the finding.
Gaming, Creative & AI Inference Validation
Raw benchmark scores are marketing. We capture frametime distributions — the statistical shape of how a GPU delivers frames over time. Four titles run their built-in benchmarks, one recorded pass per resolution: Premium at 1080p, 1440p and 4K (12 runs); Standard and Re-Certification at the two resolutions set by the card's class (8 runs), or all three when the model is not yet classified. Premium adds the Creative & AI suite.
All FPS figures are time-weighted. The score weights the consistency gap g = 1 − FPS₁%/FPSavg at 0.7 and the stutter magnitude s = 1 − FPS₀.₁%/FPS₁% at 0.3:
GOLD and PLATINUM need a score of at least 88 in every measured resolution; PLATINUM also needs at least 95 in one. A run whose stutter magnitude exceeds 0.60 is a Soft Limit: the technician must justify it in writing and re-examine the power rails from Phase 1. These thresholds are engineering priors pending fleet calibration (n ≈ 300).
Certificate Finalization & Digital Twin Issuance
Every data point from Phases 1–4 is compiled by the Assurd Rules Engine — not a technician — into a Hardware Grade. The technician proposes. The Rules Engine decides. The resulting Digital Certificate is cryptographically signed and published to the Assurd public registry as an immutable Digital Twin of this specific hardware asset.
| Grade | Condition |
|---|---|
| PLATINUM | Premium only. Health score ≥ 90, no disclosed Soft Limit, Fluidity ≥ 95 in one resolution and ≥ 88 in every measured one, Hotspot Δ < 12°C. |
| GOLD | Health score ≥ 78, Fluidity ≥ 88 in every measured resolution, Hotspot Δ < 18°C. The highest grade for Standard and Re-Certification, even when the earlier certificate was PLATINUM. |
| SILVER | Health score ≥ 65. Good working condition with documented findings. Also the cap when no gaming data was measured. |
| BRONZE | Health score ≥ 50. Functional but degraded. Includes units with 'TIM Degraded' thermal verdicts. |
Each certificate is signed with an ECDSA P-256 (ES256) key held in Google Cloud KMS, over its RFC 8785 canonical JSON. Anyone can verify it with the public key from the Assurd registry, in the browser or offline with OpenSSL. Any change to the signed bytes breaks the signature.
