20 canonical GPUs fully fit. 11 of them have a fresh current price. 9 compatible GPUs have no current price.

Formula: MIN(live fresh Amazon-matched board-partner SKU price) WHERE compatibility = FITS_IN_VRAM. Sort: price ASC, advertised VRAM ASC, canonical GPU id ASC. Prices are the lowest fresh Amazon-matched board-partner SKU, not MSRP or a street-price average.

Among 11 canonical GPUs with a fresh matched Amazon offer currently available in RigForAI. Ranked 11. Unpriced compatible: 9. This is not the entire US market — only canonical GPUs with a fresh matched Amazon offer currently in RigForAI.

Compatible — current price unavailable

These GPUs calculate as a full VRAM fit. They are not inserted into the current-price ranking because RigForAI has no fresh matched Amazon offer for them. That is not the same as too expensive or incompatible.

Supported llama.cpp decode per current $1,000

Not ranked here: comparable published MEDIUM-or-higher-confidence llama.cpp decode predictions with a fresh price are unavailable for this workload. Raw Phase 5 estimates may still appear on GPU and comparison pages.
