Lucky Facebook Marketplace shopper finds souped-up prototype GTX 2080 Ti inside a $500 PC — mythical Nvidia project features 12GB of VRAM and higher memory bandwidth

A Reddit user made an incredible discovery of a rare prototype Nvidia GeForce GTX 2080 Ti GPU inside a $500 PC bought from Facebook Marketplace. The card, resembling a Founders Edition model, features 12GB of GDDR6 VRAM, a wider memory bus, and higher bandwidth compared to the retail version. It is branded as "GeForce GTX," hinting at its early engineering sample status before RTX branding was finalized. The prototype's specifications suggest Nvidia may have explored a more powerful configuration before settling on the RTX 2080 Ti design, or it could have been part of testing for an unreleased Titan or workstation variant. Such prototypes are typically kept confidential, making this find a valuable piece for tech enthusiasts and collectors.
