A Redditor compiled this week's eBay listings (US-shippable, fixed-price, single cards) for used datacenter GPUs, ranked by $/GB of VRAM, using the 10th percentile of credible listings:
- Cheapest: Tesla P100 16GB from $174 ($10.9/GB), P40 24GB $280, V100 16GB $220 ($13.8/GB — but 38 of the 40 cheapest are SXM2 modules needing adapters).
- Best per GB/s: P100, V100 16GB and MI50 16GB all land around $0.25/GB/s; the 3090 is the cheapest consumer card per GB/s; MI50 32GB costs under a third of a 3090 per GB.
- Steep end: A100 80GB $13,995 ($175/GB), A100 40GB $4,799, RTX A6000 48GB $4,600.
- Prices are climbing fast: an 8x V100 32GB server the author bought for $5,400 in early September now runs $13,000; MI100 rose from $1,100 to $1,490. The author doubts prices will come back down.
- Notable trend: people are having Opus 5.5 write megakernels for these old cards, with surprisingly good results.
