与高通公司的Snapdragon X75相比,iPhone SE 4的调制解调器是苹果公司的第一个内部5G调制解调器,尤其是在运营商的聚合功能方面,预计将具有重大限制。
据报道,Apple的调制解调器支持四载流汇总(4X CA),该调制解调器允许在最佳条件下达到4 Gbps的峰值下载速度。相比之下,高通公司的Snapdragon X75最多可汇总5个低于6的载体,甚至可以使用MMWave的10个载体,从而使理论速度达到7 10 Gbps。这意味着配备了Snapdragon X75的设备的用户可以可能会更快地下载和上传速度,尤其是在可以有效利用多个载体的环境中[1] [2] [3]。
此外,iPhone SE 4的调制解调器缺乏对MMWave技术的支持,这对于在人口稠密的地区实现超快速速度至关重要。与使用Snapdragon X75相比,MMWave支持进一步限制了SE 4的性能,该系列使用Snapdragon X75,并提供了低于6 GHz和MMWAVE功能[1] [2] [4]。结果,Urban Hotspots的用户可能会发现iPhone SE 4的性能比其高级同行提供的性能要慢。
总而言之,尽管苹果的内部调制解调器标志着朝着远离高通的独立性的战略转变,但与高通公司的Snapdragon X75相比,它目前的运营商聚集功能和整体速度功能都在缺乏。
