从实际性能影响来看，单核性能几乎不会受到波及，因为单核跑分通常只调度一个性能核心，而iPad Air版本依然保留了三颗性能核心。对大多数以单线程为主的日常操作，如应用启动、界面切换和轻量办公，这一差异并不明显。真正拉开差距的是多核负载和依赖Metal的图形、专业应用：在需要同时调用更多CPU和GPU核心的场景下，iPad Air版M4将落后于同为M4的iPad Pro，更不可能接近采用M5芯片的新款iPad Pro的性能水准。

When TCL showed off its RayNeo Air 4 Pro smart glasses at CES 2026, I was impressed, and I wrote at the time that competitors like Xreal should be worried. Despite the relatively affordable price tag, the glasses have super-bright OLED displays that support HDR10, something never seen before in smart glasses. TCL describes them as "head-mounted TVs," and that's what they feel like.，详情可参考体育直播
