Certificate of Hardware Verification

AMD Radeon RX 6600

This certifies that the graphics processing unit described herein has completed GPU Cert's independent hardware verification protocol and is issued the result below.

GPU Specification

Device: AMD Radeon RX 6600
Total VRAM: 8.0 GB
GPU UUID: PCI_VEN_1002&DEV_73FF&SUBSYS_50221462&REV_C7_6&3B7802B1&0&00000009A
PCI Device ID: 0x73FF
VBIOS Version: unknown
Hardware Fingerprint: d842bc356eeff0727bbb6e52d6ed949b4a4e7fe237ddd4e606146140b1b61fac
Identifies this model, memory size and BIOS, not the individual card. AMD exposes no per-card identifier, so this cannot distinguish two cards of the same model, and it changes if the card moves to another machine.
PCIe Link Width: x8 of x8 max
Client Version: 0.6.2

Verification Protocol

Stress Test

Sustained GPU load via a hand-written Vulkan compute kernel

Duration: 5m 00s
Dispatches: 6,661
Peak temperature: 60°C
Thermal stability: Stable

VRAM Pattern Test

Bit-pattern write/verify sweep across active memory

Duration: 5m 00s
Coverage: 6.6 GB (83%)
Passes run: 3,762
Errors: 0

Render Integrity Test

Deterministic graphics-pipeline render, checked pixel-for-pixel against the expected output, catches rasterizer/shader-core defects the compute and VRAM tests can't see

Duration: 0m 45s
Frames rendered: 11,190
Pixels checked: 733,347,840
Mismatches: 0
