The x86 protection model is notoriously complex, with four privilege rings, segmentation, paging, call gates, task switches, and virtual 8086 mode. What's interesting from a hardware perspective is how the 386 manages this complexity on a 275,000-transistor budget. The 386 employs a variety of techniques to implement protection: a dedicated PLA for protection checking, a hardware state machine for page table walks, segment and paging caches, and microcode for everything else.

不是因为算力不重要，而是模型和模型之间的差距，正在以肉眼可见的速度收窄。大模型之间当然有差异，但对于绝大多数企业的实际需求来说，它们已经"够用了"。当"够用"成为基准线，比拼谁的模型更聪明就变成了一场没有终点的消耗战，边际的改善却极为有限。
