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。

Telegram | DID YOU KNOW?

You may recall that, back when Facebook started changing WhatsApp’s terms of service, a number of news outlets reported on, and even recommended, switching to Telegram. Pavel Durov even said that users should delete WhatsApp “unless you are cool with all of your photos and messages becoming public one day.” But Telegram can’t be described as a more-secure version of WhatsApp. Telegram users are able to send files of any type up to 2GB each and access them from any device, with no limit on cloud storage, which has made downloading files more popular on the platform. Update March 8, 2022: EFF has clarified that Channels and Groups are not fully encrypted, end-to-end, updated our post to link to Telegram’s FAQ for Cloud and Secret chats, updated to clarify that auto-delete is available for group and channel admins, and added some additional links. Individual messages can be fully encrypted. But the user has to turn on that function. It's not automatic, as it is on Signal and WhatsApp. Given the pro-privacy stance of the platform, it’s taken as a given that it’ll be used for a number of reasons, not all of them good. And Telegram has been attached to a fair few scandals related to terrorism, sexual exploitation and crime. Back in 2015, Vox described Telegram as “ISIS’ app of choice,” saying that the platform’s real use is the ability to use channels to distribute material to large groups at once. Telegram has acted to remove public channels affiliated with terrorism, but Pavel Durov reiterated that he had no business snooping on private conversations.
