Hardware leaker Jaykihn has shared what's believed to be the preliminary power specifications for Intel's upcoming Panther Lake-H CPUs, which are set to be used later this year in a new slate of laptops and mobile devices, which were previously shown off at CES 2025.
The alleged preliminary spec details three variants of chips within the series, denoting performance, efficiency, and Xe3 cores. These chips are set to be based on Intel's upcoming Celestial architecture. They will likely materialize as Intel's Core Ultra 300H series, and the alleged preliminary power specifications allow some speculation about the kinds of devices the company will target.
The first variant shows off a 16-core chip with a 4+8+4 configuration. Assuming this means four performance cores, eight efficiency cores, and four GPU cores. This specific configuration will likely reside in systems alongside a dedicated GPU. PL1 (Performance Base Power - PBP) and PL2 (Maximum Turbo Power - MTP) in both baseline and performance power modes will pull 25W and 64W- respectively.
The 4+8+4 configuration has notably fewer efficiency cores than its previous-gen counterparts. The same can be said for the second variant listed, featuring a 24-core configuration split into 4+8+12. This may indicate its suitability for a higher-end device with four performance cores, eight efficiency cores, and 12 GPU cores. The PBP is listed at a baseline of 25W, with an MTP of 55W. In the 'performance' mode, this changes to 25W and 64W, respectively.
The cTDP Max headroom on both chip configurations lists higher wattages, up to 80W MTP. This might imply that both chips have some headroom built for burst-heavy tasks like rendering. However, they are also set to be more efficient than the Core Ultra 200H series, which could boost into 100W+ territory.
The final listing is for a seemingly lower-end eight-core chip with a configuration of 4+0+4. This will likely be the Core Ultra 300U chip, set to be used in entry-level devices or gaming handhelds. This configuration can run with a PBP of just 15W and an MTP of 44W under the 'baseline' power mode, while it boosts up to a similar 25W PBP and 55W MTP under the 'performance' mode.
This tells us that Intel is starting to get serious about efficiency in its mobile chips. While AMD has long held the efficiency crown for x86 mobile devices, this initial power spec may be a step in the right direction for Intel. AMD has gained ground on Intel in both the desktop and laptop CPU market, with competition fiercer than ever. Intel's Panther Lake H CPUs will be produced in volume on the company's 18A (1.8nm-class) process in 2H 2025. The products are expected to be on shelves in early 2026.

It's Official – a Handheld Xbox is Coming This Fall
Microsoft'slong-rumored entry intohandheld gamingfinally has a release window: holiday 2025. The tech giant today unveiled two new devices – theROG Xbox AllyandROG Xbox Ally X– developed in partnership withASUSand created with both casual and more serious gamers in mind. The upcomingXboxhandhelds have been 'built from the ground up,' according to ASUS, with Microsoft adding that it has 'dedicated years' to get to this point. Designed with Xbox players in mind they feature contoured grips 'inspired by Xbox Wireless Controllers' that should feel instantly familiar in-hand, together with ergonomics the brands promise will provide 'all-day comfort.' They share a 7-inch, 16:9, 1080p touchscreen IPS display with FreeSync Premium and a 120Hz refresh rate. They also both feature Wi-Fi 6 and Bluetooth 5.4, the same button layout and overall dimensions, but the similarities end there. TheROG Xbox Ally– the cheaper of the two, though final pricing isn't confirmed – runs on AMD's 'Ryzen Z2 A' processor, has 16GB RAM and a 512GB internal storage, and though capable of outputting 1080p, Microsoft says this model is targeted at 720p gaming owing to its less powerful specs. It includes a 60Wh battery and two USB 3.2 Type-C ports. Meanwhile, the more powerfulROG Xbox Ally Xruns on AMD's improved 'Ryzen Z2 Extreme' processor, features 8GB more RAM (24GB in total) and double the internal storage with a 1TB SSD. It also includes a larger 80Wh battery and one of its Type-C ports is the faster USB 4 kind. Both models, however, feature microSD card readers, allowing users to upgrade their storage easily. Like ASUS' originalROG AllyandROG Ally Xbefore them, the newly announcedROG Xbox AllyandROG Xbox Ally Xare still – technically speaking –gaming PCsrunning Windows under the hood. But unlike the originals, they're set to launch with a completely new front-end developed specifically for handheld gaming. In other words, instead of booting into the standard, not-so-gamer-friendly Windows interface like a regular PC, the new devices will launch into a custom interface designed by Xbox's own engineers – a 'full-screen [Xbox] experience' that Microsoft says has been 'optimized specifically for handheld gaming.' The updated user interface (UI) isn't just a visual refresh, though, and it's not only about improving user experience (UX). Instead, the software tweaks – subtle on the surface – are designed to help the system better leverage its hardware for improved performance across the board: by stripping out some of the backend processes typical of a standard Windows machine, the new Xbox handhelds will have more RAM and other computing power at their disposal. Microsoft and ASUS have not confirmed a release date or final pricing as of yet, but stay tuned for more information as we get it. In the meantime, check out the official trailer below.

AMD acquires Untether AI team
AMD has acquired the team behind Untether AI, a developer of AI inference chips claimed to be known for their energy efficiency and speed in edge environments and enterprise data centres, CRN reported. As part of the acquisition, Untether AI executive Bob Beachler announced that the startup will cease supplying or supporting its speedAI products and imAIgine software development kit. 'AMD has entered into a strategic agreement to acquire a talented team of AI hardware and software engineers from Untether AI,' the media outlet reported, citing an AMD spokesperson as saying. 'The transaction brings a world-class team of engineers to AMD, focused on advancing the company's AI compiler and kernel development capabilities as well as enhancing our digital and SoC design, design verification, and product integration capabilities. We are excited to welcome the team's unique expertise to AMD,' the spokesperson added. This acquisition is part of AMD's ongoing strategy to expand its AI computing capabilities and challenge Nvidia's dominance in the field. Earlier in June 2025, AMD snapped up compiler startup Brium to strengthen its open-source AI software ecosystem. Established in 2018 in Toronto, Untether AI focused on AI inference chips for edge environments and data centres, utilising an "at-memory" architecture to enhance performance and decrease power consumption. In October 2024, Untether AI launched the speedAI240 Slim AI inference accelerator card, claiming it demonstrated three times greater energy efficiency in data centres and six times greater in edge environments compared to competitors. The card was adopted by companies such as J-Squared Technologies and Ola-Krutrim, with a partnership for co-developing next-generation data centre solutions. Untether AI also had partnerships with companies such as Arm, Ampere Computing, Asa Computers, Boston, NeuReality, and Vertical Data.

Wow, Samsung Galaxy Watch 8 will look completely different, according to "official" image leak
When you buy through links on our articles, Future and its syndication partners may earn a commission. Quick Summary Images have leaked showing the Samsung Galaxy Watch 8 range – and there's a big change. The case shape looks set to follow the Galaxy Watch Ultra this time out. After months of spec leaks and rumours, we've finally got a good look at the upcoming Samsung Galaxy Watch 8 range. That's because a series of renders have just been spotted and shared by the team at Android Authority. The next-gen smartwatch has been the subject of the rumour mill in recent weeks, after a Samsung executive confirmed an "innovative" design would be coming on the new models. Now, we know exactly what that will look like – and it's one of my favourites. The models appear to utilise the squircle case shape from the Samsung Galaxy Watch Ultra. In my humble opinion – and as someone who spends most of my week surrounded by pricier luxury watches – that is the best looking smartwatch on the market right now, so I'm really excited to see more models follow suit. The two models shown are the base model Galaxy Watch 8 and the Galaxy Watch 8 Classic. The latter is the more interesting of the two – released every two years, that features a physical rotating bezel for a more traditional feel. It will certainly be interesting to see how that is implemented on the more squared case shape. The report also suggests that the Classic variant could take the Quick Button and stronger vibration from the Ultra, which would make it an appealing prospect. Speaking of the Ultra, it looks as though we might not see a new version of that model this time out. The team found the codename for the original Galaxy Watch Ultra variant, suggesting that it may just receive some new software features. That's no bad thing, though. It's biggest competitor – the Apple Watch Ultra 2 – has moved to a bi-annual release cadence after arriving just 12 months after its successor. That felt like a step to soon for most, who weren't willing to fork out so much cash in such a short period of time. Elsewhere, we also learned that there will be two sizes for the base model. There's no word on the actual sizes for those models, but the code appears to reference a small and a large option for users.
