It looks like more “ghost” hardware from the Ampere era is escaping the lab. Recently, a Reddit user (Tommyjones91) shared a surprising discovery: they unknowingly purchased two Nvidia RTX 3080 Ti 20GB Founders Edition engineering samples on the second-hand market.
This isn’t the first time we’ve seen this specific unicorn; a similar sample surfaced on eBay earlier this year, eventually selling for a staggering $1,999.
A Case of Mistaken Identity
The buyer originally thought they were purchasing standard 12GB retail cards. It wasn’t until the cards were installed and checked via GPU-Z that the “20GB” VRAM capacity was revealed. While more memory sounds like a dream upgrade, owning an engineering sample (ES) comes with significant hurdles:
- Driver Lockouts: Standard GeForce drivers do not officially support this hardware ID.
- The Workaround: The owner had to use a third-party driver patcher to bypass Nvidia’s checks just to get version 581.94 to work.
- Uncertain Future: Because Nvidia never intended these for the public, any future driver update could potentially brick the card’s functionality.
Specs: The 20GB Trade-off
Why did Nvidia scrap this version? The specs give us a clue. While the 20GB model offers way more room for high-res textures and compute workloads, it utilizes a 320-bit memory bus.
Compared to the retail 3080 Ti’s 384-bit bus, the 20GB version actually has lower memory bandwidth. This placed the card in an awkward spot—better than a 3080, but potentially choking in scenarios where the 3090’s full bandwidth was required.
Why Are These In The Wild?
Typically, engineering samples are strictly controlled and supposed to be destroyed or returned to Nvidia after validation. Seeing two of these surface within six months suggests a small batch was never accounted for.
While the “build quality is amazing,” as the owner noted, these remain high-risk collectors’ items rather than practical gaming upgrades. If you’re hunting for used deals on eBay or Reddit, keep a close eye on those labels—you might just stumble onto a piece of unreleased history.
