NVIDIA has released details of this year's Rubin architecture.
NVIDIA CEO Jensen Huang officially unveiled the architecture details of this year's upcoming Rubin chip at CES 2026. The chip is currently in production and mass shipments are expected to begin in the second half of this year.

The Rubin platform comprises six components: a Vera CPU, a Rubin GPU, an NVLink 6 switch, a ConnectX-9 SuperNIC, a BlueField-4 DPU, and a Spectrum-6 Ethernet switch. It supports AI training and processing with reduced total cost. Huang stated that the current challenge in the AI ​​hardware world is the demand for both training and inference of AI models increasing faster than hardware capabilities can support, and Rubin addresses this problem. With five times better performance compared to the Blackwell architecture,

a single rack of Vera Rubin NVL72 will contain 72 Rubin GPUs and 32 Vera CPUs, all connected via NVLink 6, with a total of 20.7TB of HBM memory and 54TB of LPDDR5x memory. It supports inference runs at 3.6 EFLOPS and training runs at 2.5 EFLOPS. The cost per token is ten times lower than Blackwell.

Rubin will begin shipping through partners in the second half of this year, while major cloud providers will begin deployment in the first half.

  Missing Chat History: Google Gemini Users Report Widespread Sidebar Glitch According to reports from PiunikaWeb , a significant number of Google Gemini users are experiencing a sudden disappearance of their conversation history from the platform's sidebar.

This suggests that the data itself has not been permanently deleted. Instead, the glitch appears to be a server-side loading error , where the application is temporarily unable to retrieve and display stored logs from Goog...

The Fall of the Walled Garden: How EU Regulation is Rewriting the iPhone’s DNA in 2026 For over a decade, the "Golden Rule" for iPhone users was simple: "If you want an app, you get it from the App Store ." However, in 2026, this ironclad policy has been shattered across the European Union (EU). Driven by the Digital Markets Act (DMA) , a landmark antitrust regulation, the EU has successfully forced Apple to dismantle its long-standing monopoly. Breaking the Gatekeeper’s Grip The EU identifies Apple as a "Gatekeeper" a tech giant with excessive control over software access. Under the DMA, Apple has been compelled to open iOS to several transformative changes: Third-Party App Stores: Users can now install marketplaces like the Epic Games Store or AltStore. Web Distribution: Developers can offer direct app downloads from their official websites.

The Valuation Gap: Etsy’s Strategic Exit Etsy originally acquired Depop in 2021 for $1.625 billion , meaning this sale represents a significant loss in valuation. This move aligns with Etsy’s current broader strategy to divest from specialized subsidiaries acquired during the pandemic-era e-commerce boom. Over the past year, Etsy has been offloading various assets, including the musical instrument marketplace Reverb and the Brazilian handmade marketplace Elo7 . Depop by the Numbers Depop remains a powerhouse in the "re-commerce" sector, particularly among younger demographics. Key performance metrics from the past year include: Gross Merchandise Value (GMV): Approximately $1 billion . Active Communi...
