Grabbed this a few days ago. Still trying to nail down the exact model it was intended to be, but it may have been early enough to not have any specific model yet. The best we could figure it was meant to be a Radeon Pro V420 (now added to the database) just judging by the suspicious gap between V320 and V520, which skips right over Vega 20.
This is full Vega 20 on what would become the Radeon Pro VII's PCB 21 months later; the chip code matches that of Instinct MI50 and MI60. The cooler and shroud design isn't completely unique, it shares the design cues of the later Instinct MI100 CDNA1.0 card, but I was surprised to see such a small heatsink albeit with a sizeable vapor chamber. The Hitachi thermal pad I've seen on other Vega engineering boards (as well as Radeon VII) shows up here as well. No drivers recognize it so I forced an install using the Pro VII's config file. Surprisingly this works perfectly fine, again lending some credence to the card being intended to be a workstation card and not pure compute like Instinct. It's important to note that AMD never released a consumer facing Vega 20 XL die config except the Mac Pro Vega II MPX cards. This card features a pretty minimal chip power limit of 165W and caps the voltage at 1.15v, while the HBM2 is limited to 0.85v. This leads to a paltry 1450-1510MHz average boost clock, but also a very nice 64C (83C hot spot) core temp with the fan barely running around 1850RPM. Fun note, AMD marked what variant and revision of Samsung HBM2 is on the package, but along with the other incorrect specs GPU-Z misidentifies it as Hynix.

They were my favourite brand and I would only buy Abit mobos at the time. I never got to buy a graphics card though.
