CPU cache L1, L2,L3：聊一聊CPU快取的作用，是越大越好嗎?

聊一聊CPU快取的作用，是越大越好嗎?

2020年2月23日—CPU快取分為三類，一級快取(L1)、二級快取(L2)和三級快取(L3)。我們現在常見的是三級快取。但是CPU在實際資料讀取中重要的卻是一級快取，因為一級快取 ...。其他文章還包含有：「cachememoryBy」、「CPUcache」、「CPUCacheBasics」、「CPUCache原理探討」、「CPU缓存：L1、L2和L3缓存之间的区别翻译」、「L1,L2」、「什么是L1L2L3Cache?」、「記憶體階層」

L1 or L2 can be significantly faster than L3, though L3 is usually double the speed of DRAM. With multicore processors, each core can have dedicated L1 and L2 cache, but they can share an L3 cache. If an L3 cache references an instruction, it is usually e
