A rare NVIDIA GeForce RTX 3080 Ti 20 GB engineering sample has surfaced through the TechPowerUp community, acquired by forum member ChintzyPC. The card, based on the GA102 GPU, represents an unreleased variant of NVIDIA's Ampere architecture that was never officially launched to consumers. The engineering sample was purchased for just $200 per unit through a local seller, arriving in formal packaging despite the vendor disappearing shortly after the transaction.

This unusual GPU features 20 GB of VRAM on a 320-bit bus and uses a hybrid RTX 3090-style PCB design. TechPowerUp's database lists a $1199 MSRP for the RTX 3080 Ti 20 GB variant with a January 2022 release date, though NVIDIA never officially disclosed these past-gen models. The card requires a patched driver to function and delivers gaming performance comparable to the standard RTX 3080 12 GB model. However, compute workloads cause crashes, and while overclocking works normally, the firmware remains heavily locked down.

A commenter and VideoCardz suggest only a limited batch of retail-grade MSI RTX 3080 Ti 20 GB cards may have leaked through back channels in Russia during 2021. The engineering sample's VGA BIOS has been uploaded to TechPowerUp's collection for enthusiasts to examine. This discovery offers rare insight into NVIDIA's product development process and the unusual variants that never made it to market.
