Unverified速率越高发热与功耗越大：千兆网卡几乎不发热免驱即用，2.5G轻微发热，万兆电口网卡满载功耗可达5-15W需散热片，日常仅上网千兆足矣84% similarUnverified端口速率与散热的权衡：万兆电口（10GBASE-T）发热远高于万兆光口（SFP+），万兆电口机型几乎都需主动散热风扇，追求静音应优先选SFP+光口方案70% similarUnverified万兆电口(10GBASE-T)网卡发热和功耗显著高于万兆光口(SFP+)，短距离机架内互联建议用SFP+光模块/DAC线，长距离布线或复用现有网线才选电口70% similarUnverified小机箱或电源余量不足时不建议直接上双卡工作站显卡，多卡需要PCIe插槽间距、机箱风道和≥1000W电源，散热不良会导致降频甚至宕机，需先确认整机供电与散热方案70% similarUnverified万兆速率跑铜缆(10GBASE-T)需CAT6A网线且距离≤55米(CAT6)，长距离或省电应选SFP+光模块方案；SFP+网卡功耗和发热明显低于万兆电口网卡70% similar
