Intel SMT多线程回归或仅限服务器 酷睿不会有：核心数够多了_我的网站

一 |     8月24日消息，在12代酷睿处理器之后，Intel放弃了使用多年的SMT多线程技术HT（超线程），但现任CEO陈立武多次表示在这点上他们犯了错，会让SMT技术回归Intel处理器。    Filmmaker Subhash Ghai remembered the legendary actor Dharmendra with deep affection and admiration. When the director went to the late actor with the script of Krodhi, he not only said yes to it but also came on board as a producer. Ghai reflected on their bond and shared personal memories that highlighted Dharmendra’s discipline, warmth and humility.          He told Filmfare, "I learnt from him that daily physical exercise and living with laughter are essential. During the shoot of Krodhi, he had a fever, but after seeing a tough scene ahead, he asked me to give him one hour. He started exercising on set and then shot till late evening."     Ghai also recalled how Dharmendra never hikes his fee even after delivering blockbusters. He continued, "I remember when I narrated the script of Krodhi to him for the first time at his house. He instantly said that not only would he act in it, but he would also produce it under his banner. I was speechless. He never went after money, only after a good role. He never increased his fee even after any blockbuster film. We knew him as a big child and respected him deeply."                                                                 View this post on Instagram          A post shared by SG (@subhashghai1)               Actor Dharmendra, also known as the He-Man of Bollywood, breathed his last in his Juhu residence. His last rites took place in the Pawan Hans crematorium yesterday. Several noted celebrities such as Amitabh Bachchan, Abhishek Bachchan, Shah Rukh Khan, Aamir Khan, Salman Khan, Akshay Kumar, Sanjay Dutt, Anil Kapoor, Deepika Padukone, Ranveer Singh and others came to pay their last tributes to his mortal remains.     Dharmendra is survived by his wife, actress Hema Malini, his first wife Prakash Kaur, and his children, including actors Sunny Deol and Bobby Deol, and daughters Esha Deol and Ahana Deol.           Also Read: Moushumi Chatterjee: Dharmendra had a childlike soul, his smile was divine - Exclusive。

二 |     AMD之前就针对Intel不支持SMT多线程技术做过营销，认为他们会在企业级市场上占优势，所以Intel也确实需要回归SMT，不然至强处理器在可用的线程数量上就会有劣势。    但是SMT回归这事恐怕只会限于至强处理器，不会出现在客户端级处理器，也就是消费级的PC处理器，桌面及移动版酷睿不会重新支持HT超线程技术。     理由也很简单，那就是现在的PC处理器物理核心已经够多了，SMT已经没啥意义，它只会在物理核心饱和之后才启动，要知道现在的PC处理器动不动就是16-32核了，确实对SMT需求不大。

三 |     此外，SMT技术也不是没有代价的，它不是单纯的软件多线程，也有额外的物理设计，Intel多年前提到过会多占5%左右的晶体管，因此代价也不低的。    

    虽然PC处理器不会重新加入SMT技术，但未来的架构更值得期待，因为Intel在搞统一核心，不仅核心总数会很多，对单核性能也有好处，这才是大家真正需要的提升。

四 |     至于SMT回归的时间，至强处理器会在Coral Rapids这一代出现，这是面向2028年的下下代至强处理器，这一点已经在7月份的财报会议上确认了。    这一代至强的CPU内核是Griffin Cove，虽然也会用于酷睿处理器，但它应该是有两个版本，至强版支持SMT，酷睿版不支持SMT。    传闻的统一核心还要等到Hammer Lake这一代，这个代号倒是非常有意思，20多年前AMD的K8架构就用过Hammer的代号，获得了空前的成功。
