I swear to God it's too warm to do anything in the UK this week. I am barely coping in the heat if it wasn't for the array of small Ohyama Woozoo fans I have, plus an array of Meaco air circulators and more besides. Of course this week is the week that all the deals are happening - that's just the way of the world it seems - and none of us can catch a naffing break. Godspeed to anyone outside doing real work in this UK heat - can we make air con mandatory in new homes, please?

Being too hot to do anything means it's too warm to build your own PC as I see it, so to save you the hassle, I've gone on my merry way and found an array of six pre-built PC deals from up and down the price ladder across the UK and USA that should give you plenty of grunt for your favourite games. Finding discounts on pre-built PCs was surprisingly difficult, owing to the issues we've seem with everything from shortages for components to pesky overpricing that doesn't do anybody any favours, meaning that the whole pricing structure for certain tiers of PC have shifted up somewhat, which doesn't help anybody.

The six PCs I've put below have been picked out in the following order. First based on region, and then in order of mid-range, budget and then expensive - putting the one that I think is best for price to performance first and hitting a strong mid-tier choice with good power, then a more affordable choice for 1080p or 1440p gaming, and then a bit of a splurge option if you've got the spare cash to play at 4K. Given the way things are these days, I haven't gone mad with the latter choice and specced out a money-no-object choice, and kept to things that are a bit more reasonable given the circumstances for at least a hint of affordability.

Of course, we're sticking with the fact this is anti Prime Day coverage after all, so none of these deals are from The Retailer Who Must Not Be Named, instead from either PC builders directly or larger retailers with surpisingly good deals given the current context. If you're on the lookout for more deals after this, then you can check out James' master guide for our RPS Anti Prime Day deals coverage, or my roundup of seven more excellent deals across the UK and USA. Without further ado, here are six prebuilt PC deals I've spotted from other retailers that I think are worth your time.

What happens when you give AI coding agents a lab full of robotic arms, some compute resources, and a “generous token budget” for teaching the robots various tasks? The agents can apparently figure out a training regimen that teaches the robots to successfully cut zip ties and even insert GPUs into thin sockets on motherboards.

That glimpse into how AI can act in a fully autonomous way to automate robot training was made possible by a new agent harness framework—software that wraps around AI models to enable their use of various tools while also providing capabilities such as memory, context, constraint, and feedback loops. That agentic harness, called ENPIRE, was developed by robotics researchers at the Nvidia GEAR (Generalist Embodied Agent Research) lab alongside collaborators from Carnegie Mellon University in Pittsburgh and the University of California, Berkeley.

“A part of our NVIDIA GEAR lab now self-improves tirelessly overnight,” wrote Jim Fan, director of AI at NVIDIA, in a LinkedIn post. “We just read the reports in the morning.”

Back when I first tried a G-Sync Pulsar monitor at an Nvidia shindig in February, I clung to the hope that maybe, finally, gaming display tech had made its first real breakthrough in years. Dozens, if not hundreds of samey screens would be revealed as incompetent fools in the searing light of Pulsar’s innovative genius; Nvidia’s own frame generation systems would weep in shame that they once tried to mock up the fluidity and motion clarity that Pulsar could deliver for real.

Now, I have one such Pulsar monitor – an identical 1440p, 360Hz Asus ROG Strix XG27AQNGV to the one from that demo – to test at length, and can at last say with certainty: yeah, s'alright. Pretty decent. Doesn’t make much of a difference in some games but it can look quite nice. Probably too expensive, mind. Why can’t I hear any weeping?

Chipmaker Nvidia is planning to sell $25 billion of investment-grade debt in the US on Monday, its first bond sale in five years, in a test of investor appetite for further exposure to the AI sector.

In a marquee seven-part bond offering, the company will issue a wide range of maturities from two years to 30 years, according to a term sheet seen by the FT.

The issuance was upsized from $20 billion after receiving more than $85 billion in orders by early afternoon in New York, according to people familiar with the deal.

Microsoft's Build developer conference kicked off today, and as with almost everything the company has done in the last few years, Microsoft's opening keynote focused overwhelmingly on AI and other closely related technologies. There's Microsoft Scout, an OpenClaw-based "Autopilot" agent that can hook into Microsoft 365 data to perform tasks for users; several new AI models; an expanded preview of "Codename MDASH," which is a "multi-model agentic scanning system" meant to detect and fix software vulnerabilities.

A few of those announcements stood out to us as particularly interesting, either for esoteric technical reasons or because they seem like they may have some utility for those who aren't spending their every waking moment using generative AI tools. (Microsoft's recent efforts to make its flagship operating system faster, more reliable, more useful, and less annoying didn't really come up, but there have been plenty of other announcements on that front lately.)

On the hardware front, we didn't get any updates for existing Surface devices (not counting yesterday's Surface Laptop Ultra announcement), but we did get something new: the Surface RTX Spark Dev Box is "a compact developer PC" built around Nvidia's new RTX Spark chip with up to 128GB of built-in memory.

After years of whispers around Nvidia maybe, possibly, perhaps getting into CPU-making, they’re making it official with RTX Spark: a fully integrated laptop SoC (System on a Chip), coming to thin 'n' lights in Autumn this year.

Unsurprisingly, given the source of Nvidia’s trillions, RTX Spark has a big focus on agentic AI work, the official descriptions of which are so inducive of malaise that I can’t even bring myself to copy them in from the press release. But there is plenty of note for those who’d use their lightweight laptop to play games, as the SoC’s graphics processor is based on the same Blackwell architecture as Nvidia’s GeForce RTX 50 series of standalone graphics cards. That means it’ll support DLSS 4.5 upscaling, Multi-Frame Generation, ray tracing, Reflex, and G-Sync, all hitherto unseen (or at least extremely rare) on what is essentially integrated graphics. Unless you count the Nintendo Switch 2. And round 'ere, we don’t.

These days, Nvidia primarily sells AI data center products, and its traditional consumer devices feel like more of a side project. But the company occasionally still releases something designed for consumers. After a couple of years of rumors, Nvidia has announced an Arm-based chip designed to power Windows PCs. Dubbed RTX Spark, the new chip combines a 20-core Nvidia Grace CPU co-developed with MediaTek, up to 6,144 Blackwell-based GPU cores (the same architecture as the RTX 50-series GPUs), and support for up to 128GB of unified LPDDR5x memory.

Nvidia and its partners offered nothing about expected pricing, but both "slim Windows laptops with all-day battery life and premium displays" and "compact desktop PCs" are slated to be "available this fall" from partners including Asus, Dell, HP, Lenovo, Microsoft, MSI, Acer, and Gigabyte.

This isn't Nvidia's first chip for Windows PCs; earlier chips in the Tegra series powered several of the short-lived Windows RT tablets. But Tegra chips largely stopped appearing in consumer devices following the Tegra X1 in the late 2010s (variants power the original Nintendo Switch and the apparently unkillable Nvidia Shield TV box). Modern Arm-based PCs in the Windows 10 and Windows 11 eras have all used processors from Qualcomm.

Intel plans to ship an AI chip by the end of this year that uses cheaper memory and cooling technology than rival offerings from Nvidia and AMD, as the US chipmaker seeks to capitalize on a sharp turnaround in its fortunes.

Kevork Kechichian, who leads Intel’s data center group, told the FT that the company is “starting with the basics” as it tries to challenge its rivals in the booming market for semiconductors that power AI.

Its new “Crescent Island” graphics processing unit is designed to speed up “inference” tasks, the stage when a user makes their request, rather than the training of models, an area where Nvidia’s processors are dominant.

Donald Trump has very little leverage heading into two days of meetings with China's leader, Xi Jinping, in Beijing this week, experts say.

The thinking goes that Trump came into office with a plan that has since largely failed. He hoped to resolve the conflict in Ukraine, settle things down with Israel and Gaza, launch his Liberation Day tariffs, and quickly diversify US supply chains, all of which would have given him substantial leverage over China.

But none of that happened, and instead, Trump's escalations in Iran have only handed China even more leverage heading into talks, and Xi knows it.

Data centers may be coming to your neighborhood as side installations associated with new homes—and in exchange would offer subsidized electricity and Internet access along with backup batteries to homeowners. The company behind the plan has already begun pilot testing in preparation for a 100-home trial run this year.

The “distributed data center solution” announced by the San Francisco startup SPAN would deploy thousands of XFRA nodes that contain liquid-cooled Nvidia RTX Pro 6000 Blackwell Server Edition GPUs operating with minimal noise, according to a press release. By harnessing excess power capacity among US households, SPAN aims to quickly expand the available compute for AI workloads without the costs and delays associated with trying to build warehouse-size data centers.

“Data centers are loud, ugly, and often drive up local electricity bills,” said Chris Lander, vice president of XFRA at SPAN, in correspondence with Ars. “[This] is quiet, discreet, and makes energy more affordable for the host and community.”
