台式机追求低延迟游戏或大文件传输应选PCIe接口网卡（如AX210），实测比USB网卡延迟低、无带宽损耗；USB网卡因USB总线协议开销和供电限制，实际速率通常打7-8折

Unverified直播用途优先选USB接口采集卡，即插即用无需拆机；PCIe采集卡延迟更低（可低至个位数毫秒）但仅限台式机内置，适合对同步要求极高的多机位切换场景84% similarUnverified电竞用途优先选PCIe接口网卡而非USB，PCIe直连主板总线延迟更低且供电稳定，USB网卡在高负载下易出现丢包和延迟抖动83% similarUnverified延迟越低通常需要硬件编码或PCIe直连，成本更高且便携性差；纯直播场景延迟不敏感，USB外置卡配直通口即可，无需为超低延迟买内置卡83% similarUnverified分辨率与帧率越高、延迟越低往往需要PCIe硬件方案，但牺牲了便携性和跨设备通用性；外置USB卡通用但延迟和带宽受限80% similarUnverifiedUSB采集卡有编码延迟（普遍80-200ms），只适合直播不适合竞技游戏本地实况；追求低延迟本地游玩应选PCIe内置采集卡（延迟可低于10ms硬件直通）80% similar
