Microsoft introduces Surface Laptop Ultra with Nvidia’s RTX Spark chip inside

The Surface Laptop Ultra is what happens when Microsoft stops playing it safe.

Microsoft Surface Laptop Ultra — Microsoft

Microsoft just announced the Surface Laptop Ultra, and if you’ve been following our coverage of the NVIDIA RTX Spark chip, you already know the kind of firepower we’re talking about here.

The Surface Laptop Ultra is the most powerful laptop Microsoft has ever built. It pairs NVIDIA’s Blackwell RTX GPU with up to 128GB of unified memory, full CUDA support, and 1 petaflop of AI compute.

As we covered when RTX Spark launched, that is enough to run 120-billion-parameter AI models entirely on the device, without sending a single byte to the cloud.

The unified memory is worth paying attention to. Instead of splitting RAM between your CPU and GPU, the system dynamically allocates it wherever your workload needs it most. That means AI creation, 3D rendering, and multi-model workflows can all run simultaneously without stepping on each other.

Apple MacBooks have been benefiting from this unified architecture for years, and finally, Windows users will be able to enjoy it too.

Who is this laptop for?

Microsoft is clearly positioning this laptop for developers, creators, and AI builders who push their machines to the limit. Think massive 3D scenes, long compile cycles, and local models that would bring regular laptops to a crawling halt.

Other features of the laptop include a 15-inch mini-LED PixelSense Ultra display that goes up to 2,000 nits of peak HDR brightness at 262 pixels per inch, which is the brightest display Microsoft has ever shipped.

The haptic touchpad is also the largest ever on a Surface, and the port selection covers HDMI, USB-C, USB-A, SD card, and a headphone jack, so no hunting for dongles.

What about battery life?

Microsoft says the Surface Laptop Ultra offers all-day battery life, which is impressive given the raw power inside. The ultra-efficient CPU architecture is doing a lot of work here to keep things running without draining the battery in an hour.

The laptop comes in Platinum and Nightfall finishes and will be available later this year. Pricing has not been announced yet. But seeing how Microsoft has significantly raised the prices of its existing Surface laptops, expect these laptops to burn a serious hole in your wallet.

China’s AI talent shortage has tech giants recruiting teenagers

Forget campus recruiting, china's biggest tech firms are betting on teenage coders.

Artificial Intelligence

A 13-year-old boy in Hangzhou has already won national AI competitions and built a following of more than 136,000 people online, all while his dad tries to figure out how to guide him through a field that barely existed when he himself was growing up. That family's situation, first reported by Rest of World, says a lot about where China's tech industry is heading right now.

Companies used to wait for graduates to walk through the door. Now they're reaching further back, first to undergrads, and increasingly to teenagers, hoping to spot rare talent before anyone else gets to them.

OpenAI says AI models autonomously pulled off a major hack, but only a Chinese AI helped recovery

OpenAI

OpenAI’s latest cybersecurity test produced a result that sounds like a cautionary sci-fi script. Its AI models managed to escape their sandbox and reached the open internet. This is where things took a scary turn as it began hacking Hugging Face to steal the answers to the test they were taking.

The company says GPT-5.6 Sol and a more capable unreleased model autonomously chained together vulnerabilities across OpenAI’s research systems and Hugging Face’s production infrastructure. OpenAI has described the event as an unprecedented cyber incident.

TSMC might set up a price hike that could come straight for your next phone, laptop, or tablet

Here's what TSMC's rumored 10% chip price increase actually means in dollar terms, and why your next phone or laptop could end up costing more.

TSMC Fab

My wallet flinched the second I saw the words "TSMC" and "price increase" in the same headline, and honestly, yours should too.

Turns out the company behind the silicon powering basically every flagship device out there, including Apple’s A-series and Qualcomm’s Snapdragon processors, is reportedly about to make all of it a little pricier.
