英特尔宣布了基于Haswell架构的第四代 Core处理器。首批公布是高端的四核 Core i7和Core i5，第四代低端Core i3和Pentium，以及超级本使用的低功耗处理器尚未宣布。Haswell架构加入了事务性同步扩展，支持硬件事物内存，整合了电压调节器，理论上能在增加性能的同时不会增加功耗。根据Anandtech和Tomshardware的评测，Haswell处理器在系统空闲时的消耗有显著降低，但在系统活跃情况下的能耗并不显著，事实上每瓦性能几乎没有什么变化。由于AMD不存在能与Core i7抗衡的高端CPU，所以各大媒体主要将高端的英特尔处理器和中低端的AMD APU处理器进行了比较，显示Core i7的集成显卡HD Graphics 4600已在许多测试（如 OpenCL）中能战胜 APU中的集成显卡。从性价比角度看，AMD还能勉强维持轻微优势。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.
