Китайцы смогли сделать первый оптический чип, сравнимый по вычислительным мощностям с Nvidia — Meteor-1. Он достигает 2560 TOPS (тера-операций в секунду) при частоте 50 ГГц, что сравнимо с NVIDIA 5090 (3352 TOPS).

При этом инженеры из Шанхайского института оптики и Наньянского технологического университета утверждают, что Meteor-1 практически не греется и у него низкое энергопотребление. Создателям удалось добиться этого благодаря решению фундаментальной проблемы оптических чипов — их система может поддерживать более 100 частотных каналов в одном фотонном чипе. Обычно их в 100 раз меньше.

«Это похоже на превращение однополосного шоссе в супермагистраль, способную пропускать сотню транспортных средств параллельно, значительно увеличивая пропускную способность в единицу времени без изменения аппаратного обеспечения чипа» — заявил Хан Силин из SIOM.

Из минусов — до коммерческого использования пока что ещё далеко, так что пока китайским ИИ-лабораториям придётся обходить санкции США другим путём.

Should I buy bitcoin?

“To the extent it is used I fear it’s often for illicit finance. It’s an extremely inefficient way of conducting transactions, and the amount of energy that’s consumed in processing those transactions is staggering,” the former Fed chairwoman said. Yellen’s comments have been cited as a reason for bitcoin’s recent losses. However, Yellen’s assessment of bitcoin as a inefficient medium of exchange is an important point and one that has already been raised in the past by bitcoin bulls. Using a volatile asset in exchange for goods and services makes little sense if the asset can tumble 10% in a day, or surge 80% over the course of a two months as bitcoin has done in 2021, critics argue. To put a finer point on it, over the past 12 months bitcoin has registered 8 corrections, defined as a decline from a recent peak of at least 10% but not more than 20%, and two bear markets, which are defined as falls of 20% or more, according to Dow Jones Market Data.
