X 用户公开了华为海思 AI 芯片昇腾 910、昇腾 910B 和昇腾 610 的集成电路布局图(Die Shot)。华为是在 2019 年宣布了昇腾 910,它由台积电代工,采用 N7+ 工艺;而昇腾 910B 则由中芯国际代工,采用 N+1 工艺,属于 7 纳米节点。昇腾 910 由 1 个 Virtuvian AI 处理器、1 个 Nimbus V3 I/O 处理器芯片、四个 HBM2E 内存栈和两个用于一致性的虚拟芯片构成。其中 Virtuvian 由 32 个达芬奇 Max AI 核心构成。芯片的尺寸为 14.6 毫米 × 31.25 毫米,面积 456.25 平方毫米。相比之下,中芯国际的版本尺寸为 21.32 毫米 × 31.22 毫米,面积达到了 665.61 平方毫米,明显要大得多。昇腾 910B 的 Virtuvian 由 25 个达芬奇 AI 核心构成。可能的原因包括中芯国际的工艺晶体管密度低于台积电,或者海思大幅增强了达芬奇核心以至于减少了核心数量。

Telegram | DID YOU KNOW?

The regulator said it has been undertaking several campaigns to educate the investors to be vigilant while taking investment decisions based on stock tips. Andrey, a Russian entrepreneur living in Brazil who, fearing retaliation, asked that NPR not use his last name, said Telegram has become one of the few places Russians can access independent news about the war. "There is a significant risk of insider threat or hacking of Telegram systems that could expose all of these chats to the Russian government," said Eva Galperin with the Electronic Frontier Foundation, which has called for Telegram to improve its privacy practices. The Securities and Exchange Board of India (Sebi) had carried out a similar exercise in 2017 in a matter related to circulation of messages through WhatsApp. Since its launch in 2013, Telegram has grown from a simple messaging app to a broadcast network. Its user base isn’t as vast as WhatsApp’s, and its broadcast platform is a fraction the size of Twitter, but it’s nonetheless showing its use. While Telegram has been embroiled in controversy for much of its life, it has become a vital source of communication during the invasion of Ukraine. But, if all of this is new to you, let us explain, dear friends, what on Earth a Telegram is meant to be, and why you should, or should not, need to care.
