英特尔工程师谈客户端处理器取消超线程：同功耗面积下性能更出色
英特尔高级工程师Ori Lempel表示，酷睿Ultra 200系列取消超线程设计，因无超线程核心在同功耗和面积下表现更优。测试显示，关闭超线程可降低15%功耗和面积，性能提升27.76%。
取消超线程还减少芯片设计复杂度，降低安全风险，并加速架构迭代。客户端处理器核心数增加，超线程优势减弱，而无超线程设计更适合游戏等需可预测性能的场景。
服务器场景仍保留超线程，因企业级应用需要高线程密度。

China’s stock markets are some of the largest in the world, with total market capitalization reaching RMB 79 trillion (US$12.2 trillion) in 2020. China’s stock markets are seen as a crucial tool for driving economic growth, in particular for financing the country’s rapidly growing high-tech sectors.Although traditionally closed off to overseas investors, China’s financial markets have gradually been loosening restrictions over the past couple of decades. At the same time, reforms have sought to make it easier for Chinese companies to list on onshore stock exchanges, and new programs have been launched in attempts to lure some of China’s most coveted overseas-listed companies back to the country.
Bitcoin is built on a distributed digital record called a blockchain. As the name implies, blockchain is a linked body of data, made up of units called blocks that contain information about each and every transaction, including date and time, total value, buyer and seller, and a unique identifying code for each exchange. Entries are strung together in chronological order, creating a digital chain of blocks. “Once a block is added to the blockchain, it becomes accessible to anyone who wishes to view it, acting as a public ledger of cryptocurrency transactions,” says Stacey Harris, consultant for Pelicoin, a network of cryptocurrency ATMs. Blockchain is decentralized, which means it’s not controlled by any one organization. “It’s like a Google Doc that anyone can work on,” says Buchi Okoro, CEO and co-founder of African cryptocurrency exchange Quidax. “Nobody owns it, but anyone who has a link can contribute to it. And as different people update it, your copy also gets updated.”
