对比中芯国际和台积电的昇腾 910 和 910B

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。

For example, WhatsApp restricted the number of times a user could forward something, and developed automated systems that detect and flag objectionable content. Telegram has become more interventionist over time, and has steadily increased its efforts to shut down these accounts. But this has also meant that the company has also engaged with lawmakers more generally, although it maintains that it doesn’t do so willingly. For instance, in September 2021, Telegram reportedly blocked a chat bot in support of (Putin critic) Alexei Navalny during Russia’s most recent parliamentary elections. Pavel Durov was quoted at the time saying that the company was obliged to follow a “legitimate” law of the land. He added that as Apple and Google both follow the law, to violate it would give both platforms a reason to boot the messenger from its stores. Anastasia Vlasova/Getty Images The news also helped traders look past another report showing decades-high inflation and shake off some of the volatility from recent sessions. The Bureau of Labor Statistics' February Consumer Price Index (CPI) this week showed another surge in prices even before Russia escalated its attacks in Ukraine. The headline CPI — soaring 7.9% over last year — underscored the sticky inflationary pressures reverberating across the U.S. economy, with everything from groceries to rents and airline fares getting more expensive for everyday consumers. And while money initially moved into stocks in the morning, capital moved out of safe-haven assets. The price of the 10-year Treasury note fell Friday, sending its yield up to 2% from a March closing low of 1.73%.
