NVIDIA RTX 4000 Ada 20GB — Price Guide & Live Deals

RTX 4000 Ada: buyer & reseller spec sheet

Confirming the SKU. This page tracks the RTX 4000 Ada Generation, which carries 20GB of memory. The feed requires 4000 and Ada in the title and rejects titles naming other memory sizes, but it does not require 20GB, so a listing that omits the size can still appear. Confirm the memory size in the item specifics and a GPU-Z screenshot, not the title. The older Quadro RTX 4000 8GB is a different, earlier-generation card; the Ada requirement keeps it out. Likewise the RTX A4500 20GB is a separate card, and titles naming it are rejected.

Full-size vs SFF. The feed includes both the standard card and the RTX 4000 SFF Ada, a low-profile model. They are different boards sold at different prices, so check the listing photos and part number for the form factor and bracket before buying. A low-profile card will not suit a full-height slot without the right bracket, and the reverse is also true.

Traps seen while tuning. Complete workstations (HP Z-series, Cloud Ninjas builds, Dell Precision towers) list under this card's name because the GPU is the headline part, at many times the card's price; the feed rejects them, along with multi-card wholesale lots. Many sellers write "Quadro RTX 4000 Ada" for what is the Ada card, so the word Quadro alone isn't a reason to skip a listing. A large cluster of near-identical new and open-box listings ships from China; the feed is limited to US item locations and requires established seller feedback, which also drops some legitimate sellers.
