20–24 GB graphics card prices

Every graphics card with 20–24 GB of video memory we found on eBay, ranked by price per gigabyte including shipping: gaming, workstation and datacenter cards, new and used. Updated Oct 11, 2026 13:57 UTC.

Datacenter GPUs are not plug-and-play in a desktop. They have no fans, need strong airflow (a fan shroud), usually an 8-pin EPS power cable and "Above 4G decoding" in the BIOS, and most have no display outputs. SXM modules need an SXM server or an adapter board.

Buying tips

For AI and LLM work, check CUDA support: Kepler cards (K80, K40, GRID K1/K2) stopped at CUDA 11, and Maxwell, Pascal and Volta cards (M40, P40, P100, V100) are not supported by CUDA 13 — they still work with CUDA 12 builds of PyTorch and llama.cpp. Multi-GPU boards such as the K80 (2×12 GB) or M10 (4×8 GB) show up to the system as several smaller GPUs.

How this table works

We collect Buy It Now listings from eBay US several times a day and divide the total price, including shipping, by the amount of video memory. Only cards we can identify by model are listed; the memory size comes from the model (and the variant named in the title, e.g. RTX 3060 8GB vs 12GB), not from the seller's guess. Multi-GPU boards are counted by their total memory. We remove empty boxes, coolers, backplates, brackets and other accessories, cards for parts or with missing chips, mining-only cards without video outputs, laptop MXM modules, Mac Pro MPX modules, PC bundles and offers far below every other listing for the same model.
