几年前我开始了一个项目，当时 NXP 的 i.MX 9 系列 MPU 开始发布，但它们基本上无法获得，所以我选择了性能强大的 i.MX 8。现阶段，它的性能远远超过我的需求，我想换用性能小得多的微处理器。我原本打算买最小的 i.MX 8，但他们最小的 CPU 是 i.MX91。我一直在想，如果选择91型而不是更成熟的8型，会不会更好。散热是我最关心的问题，所以我认为新的总是更好，但我不知道它们是否已经“达到标准”，因为它们还比较新。更公平的比较，例如将港口升级到 8 级，也可能是一个激励因素。
你好@ceva156
您的项目的主要目的是什么？您目前使用的是哪款IMX8系列产品？

你好，
如果不需要 i.MX8 的强大多媒体 GPU 功能，i.MX91 可能更合适，并且能提供更简单、更低功耗的设计。
