酷睿i5-8250u：i5-8250u的规格是四核八线程，基准频率1.6GHz，动态加速频率3.4GHz，14nm工艺制造，6M三级缓存，15W(TDP)热功耗设计。

i7-8550u：酷睿i7 8550u 隶属于KabyLake Refresh 家族，延续14纳米工艺打造，TDP热功耗设计15瓦。它的默认工作频率是1.8Ghz，最高睿频至4.0GHz，8MB三级缓存。

回答2：

存是在内存和CPU交换数据之间可以进行高速数据交换的存储器，就像汽车里的助燃剂吧，一般是越大越好。比方说，i5-8250U和i7-8550U都是四核八线程，那么最大的区别就在于两者缓存不一样和频率不一样，但实际上，两者性能比较接近。

至于制造工艺，大家能接触到最多的就是几纳米工艺，就像发动机的制造工艺，一般说来，数字越小越好。
