Used A100 SXM4 at €2,700 vs New Radeon 9700: A Home Lab Buyer's Dilemma
Hildechis · reddit · 2026-11-11
A self-hoster on r/LocalLLaMA is weighing GPU options: bargainhardware just took in A100 40GB SXM4 cards at €2,700, and with a big case and 100+ free PCIe lanes, he could mount several via SXM-to-PCIe adapters.
- A100 pros over the R9700: CUDA ecosystem, 25% more VRAM, double memory bandwidth, nearly double compute.
- Cons: used and possibly battered cards, mounting hassle, and higher cost once adapters are factored in—the R9700 pair costs less.
- He's especially asking whether SXM-PCIe adapters are decent or a pain to work with.
