Cambricon Goes Supersonic: 4,000% Revenue Boom, But Nvidia Still Laughs from Its Throne

 China’s AI chip scene just got spicy. Cambricon, a homegrown chipmaker, pulled off an insane 4,000% revenue jump in the first half of 2025, hitting $402 million with record profits of $143 million. Talk about glow-up energy. Cambricon But let’s keep it real: while Cambricon is celebrating, Nvidia made $46.7 billion in a single quarter . That’s like bringing a water gun to a flamethrower fight. So, what’s going on? The Ban Dance : The U.S. keeps tightening export rules, cutting China off from Nvidia’s best AI chips. Even Nvidia’s “China-only” H20 chip was banned, unbanned, and slapped with a 15% revenue cut for Uncle Sam. Beijing, meanwhile, is telling its tech giants: “Maybe don’t buy that.” The Stock Party : Investors are hyped. Cambricon’s stock more than doubled this year, shooting its market cap to $80 billion .

According to Google’s latest report, a single Gemini prompt costs: ⚡ 0.24 Wh of energy → about 9 seconds of Netflix 🍿 💧 0.26 ml of water → basically five baby drops 🌫 0.033 g CO₂ → like riding a scooter for 1 km… after 1,000 prompts 🛵 So yes, your dumb “write me a haiku about pizza” request does leave a microscopic footprint. 💪 Google’s Eco Glow-Up Before you clutch your metal straws, Google wants you to know: it’s getting better. ⚡ Energy efficiency: 33x improvement in one year 🌱 Carbon reduction: 44x cleaner Basically, Gemini went from gas-guzzler to Prius… okay, maybe not a Tesla yet. 🚗⚡ 🌊 The “Tiny x Billions” Problem Here’s the kicker: while each query is small, we’re all addicted.

Có nên đầu tư vàng thời điểm này?

 Trong bối cảnh kinh tế thế giới nhiều biến động, vàng luôn được xem là một trong những kênh trú ẩn an toàn. 1. Ưu điểm khi đầu tư vàng Bảo toàn giá trị: Vàng thường giữ giá trị tốt trong thời kỳ lạm phát. Thanh khoản cao: Dễ dàng mua bán tại các tiệm vàng hoặc ngân hàng. Ít rủi ro hơn so với chứng khoán, forex. 2. Nhược điểm khi đầu tư vàng Lợi nhuận không cao: Vàng tăng giá khá chậm so với bất động sản hoặc chứng khoán. Biến động ngắn hạn: Giá vàng có thể lên xuống theo tin tức, chính sách tiền tệ. Chi phí mua bán: Chênh lệch mua – bán (spread) có thể khá cao, nhất là vàng SJC. 3.

Tránh “lướt sóng” vàng nếu không có nhiều kinh nghiệm. 👉 Tóm lại: Vàng phù hợp để giữ giá trị lâu dài , nhưng không nên kỳ vọng “giàu nhanh” từ vàng.

🌦️ La Niña Might Crash This Fall… But Don’t Freak Out

  The Forecast: Scientists say there’s a 21% chance La Niña will show up between July and September 2025, and over 50% from September to January 2026. Translation: she might come by, but she’s probably just dropping in for a coffee. ☕ Who is La Niña Anyway? La Niña is basically El Niño’s chilly cousin . She loves global weather chaos: ❄️ Northern U.S.: cold & wet 🌞 Southern U.S.: warm & dry 🌪️ Atlantic: hurricane playground But Don’t Panic: Experts say this La Niña is likely a lightweight . Think of her as the guest who eats your snacks but doesn’t touch your Wi-Fi—annoying, but harmless.

Stay cozy, enjoy your cocoa, and maybe keep an umbrella handy. ☔
