英特尔今年为移动版Haswell架构处理器引入了容量高达128MB的L4缓存，L4缓存不是直接整合在芯片上面，而是封装在一起。L4缓存容量比L1/L2/L3要大得多，其响应时间约为50-60ns，比L3缓存的响应长，但只有主内存的一半。引入L4缓存被认为能提升某些工作负荷下性能，但目前还没有多少基准测试软件能检验这一说法。现在，根据最新的消息，英特尔下一代处理器架构的桌面版本Broadwell-K（k系列比标准版更贵）也将引入128MB的L4缓存。This entry passed through the Full-Text RSS service — if this is your content and you're reading it on someone else's site, please read the FAQ at fivefilters.org/content-only/faq.php#publishers.
