Benchmarking 15 "E-Waste" GPUs with Modern Workloads

# Summary A researcher benchmarked 15 decommissioned NVIDIA enterprise GPUs (K80, P100, V100) to evaluate their viability for modern AI workloads in a homelab setting, finding that these affordable used cards ($60-$200) can still be effectively utilized despite being end-of-life hardware. The project aims to create a cost-effective 4U GPU node using older enterprise GPUs paired with cheap Xeon CPUs and dense cooling solutions, demonstrating that outdated hardware can run modern software like llama.cpp through workarounds, though power efficiency concerns limit their use for continuous high-availability applications.
