Rare NVIDIA GeForce RTX 3080 Ti 20 GB Engineering Sample Acquired by TPU Forumite

ChintzyPC, a new member of the TechPowerUp community, has kindly shared their experience of picking up an unreleased " Ampere " generation engineering sample. Their forum debut appeared in the form a very in-depth exploration of NVIDIA's very rare GeForce RTX 3080 Ti 20 GB model. Late last year a scruffy yet fairly official-looking ASUS ROG Strix non-Ti variant turned up via the Chinese second-hand market. Fortuntely, ChintzyPC has acquired a comparatively pristine example of Team Green's Founders Edition design. GA102 GPU-based GeForce RTX 3080 Ti and 3080 (non-Ti) 20 GB cards are unusual prospects, given that NVIDIA has not officially disclosed the existence of these past-gen models. TechPowerUp's GPU database lists the former, with a release date of January 2022 and a $1199 (USD) MSRP, but the GeForce RTX 3080 (non-Ti) 20 GB SKU remains unregistered.

ChintzyPC recounted an acquaintance's purchasing of two "3080 Ti 20 GB Engineering Samples" via a local seller, to the tune of $200 per unit. Surprisingly, the cards turned up in formal packaging, complete with a sticker that bears model codes, serial numbers, and barcodes. They note that not much confidence was inspired when the vendor disappeared soon after processing their friend's orders. ChintzyPC's write-up details a "mix of teardown notes, benching results, and general observations, while figuring out what exactly this thing is and how it behaves." After initial tinkering sessions, ChintzyPC concluded that their latest curio is an: "unreleased (GeForce) RTX 3080 Ti 20 GB engineering sample with GA102-250 on a hybrid (RTX) 3090-style PCB. 320-bit bus, requires patched driver. Gaming performance sits around a GeForce RTX 3080 (non-Ti) 12 GB . Compute workloads crash. Overclocks normally but firmware is heavily locked down. Very strange card, (but) a fun one to dig into...In case anyone wonders (whether) there is an uploaded version of this VGA BIOS, (it is available) here (through TPU's collection)." A commenter (Dr. Do) and VideoCardz reckon that only a limited batch of retail-grade MSI GeForce RTX 3080 Ti 20 GB cards seeped out via back channel avenues in 2021—only within Russian territories.
