算力越高的卡（H100 vs A100）单价高但单位任务耗时短，短时高强度任务用H100总成本可能更低；碎片化轻负载用中端卡反而更省

Unverified只做推理不做训练时不应购买H100/A100这类高端训练卡，推理更看重显存带宽和低精度（INT8/FP8）吞吐，L40S或L4的推理性价比远高于训练旗舰卡67% similarUnverified高耐久卡比同容量普通卡贵约50%-100%，但监控连续写入下普通卡寿命仅高耐久卡的十分之一，从「更换频率+数据丢失风险」看高耐久卡长期性价比更高64% similarUnverified处理器性能越强转码和虚拟机越流畅，但功耗和发热越高、待机电费越贵；纯备份场景选低功耗ARM机型更省电静音64% similarUnverified智能功能越丰富（能耗监测+场景编程+语音）待机功耗越高（0.5-1W），单纯用于定时开关的场景，选低功耗基础款反而更省电64% similarUnverified读写速度越高的卡（如V60/V90）价格陡增且发热更大，长时间录制发热会加速寿命衰减；普通监控用V30已足够，追求高标级反而不利于全时写入耐久64% similar
