Notebookcheck’s test of a Dell XPS 16 with an LG Display 1–120Hz panel and Intel Panther Lake suggests it’s the most power-efficient laptop yet, idling at about 1.5W and delivering nearly 27 hours of Wi‑Fi web browsing on a 70Wh pack, potentially beating MacBooks; LG Display is mass-producing a 1Hz laptop panel (Oxide 1Hz) with an OLED version planned for 2027, and Intel is collaborating with BOE on 1Hz systems.
Razer’s Blade 16 for 2026 switches from AMD to the Intel Core Ultra 9 386H “Panther Lake,” adds LPDDR5X-9600 memory for faster speeds, and keeps a slim chassis with RTX 5080/5090 options. It claims up to 60% better power efficiency and 16-core performance, starts at $3,499.99 with 5080/32GB RAM/1TB SSD, and tops out at $4,499.99 for the 5090 with 2TB. A future 5070 Ti model will come later, and the machine adds Thunderbolt 5, Wi‑Fi 7, Bluetooth 6, better OLED brightness, and updated audio.
Notebookcheck’s review of the 2026 Dell XPS 16 highlights Panther Lake-driven efficiency: idle power around 1.5 W and about 4.5 W at max brightness, with WLAN browsing tests delivering roughly 27 hours on a 70 Wh pack (well over a day). It outperforms rivals that pull 3–5 W in similar conditions, but the lack of a discrete GPU trades graphics performance for this exceptional endurance. Full benchmarks are in Notebookcheck’s XPS 16 review.
Dell has introduced the Pro Precision 7 14 and Pro Precision 7 16 mobile workstations, pairing Intel Panther Lake CPUs with up to Nvidia RTX Pro GPUs, up to 64 GB LPDDR5X RAM, and PCIe Gen 5 SSDs up to 4 TB. The 14-inch model offers a QHD+ Tandem OLED option, while the 16-inch model provides FHD/4K Tandem OLED displays with 120 Hz VRR. Both include modern keyboards and Thunderbolt 4/5 ports; base SKUs go on March 31 with GPU upgrades arriving in May, and pricing has not been disclosed.
Samsung's Galaxy Book6 Ultra is a premium 16-inch multimedia laptop that combines a vivid OLED touchscreen with an RTX 5070 GPU and Panther Lake CPU, delivering strong performance, superb speakers, and excellent OLED battery life. The chassis mimics a MacBook Pro 16, but RAM is soldered and port selection is limited (two USB‑C, one USB‑A) with no SD Express. PWM flicker at high brightness is a caveat. Priced at 3599 euros, it targets buyers wanting top-tier visuals and portability, though the MacBook Pro remains a benchmark for brightness, ports, and thermals.
Honor’s MagicBook Pro 14 2026 front-loads Intel’s Panther Lake Core Ultra 5 338H with an Arc B370 iGPU, delivering strong CPU/GPU performance in a 14.6-inch OLED, 120 Hz touchscreen. It sports 32 GB RAM (soldered), a 1 TB YMTC PC411 SSD (with a second M.2 slot), and a large 92 Wh battery that NotebookCheck reports enables long Wi‑Fi endurance (~15 hours). The chassis is sturdy and cool with quiet operation, and a haptic trackpad plus Thunderbolt 4/ports improve usability, though it’s a touch thicker than some rivals. Downsides include non-upgradable RAM due to soldering, PWM flicker, and the absence of Wi‑Fi 7 and a card reader. Prices were not announced at press time, but the overall package is described as an excellent all‑rounder with a superb OLED display and robust performance.
Notebookcheck’s early tests of Intel’s Panther Lake Core Ultra 5 338H with Arc B370 (10 Xe cores) show solid CPU performance comparable to Ryzen AI 9 465 at similar TDP, while the Arc B370 GPU delivers a notable uplift but trails the Arc B390 by a small margin. At 20W the B370 is virtually identical to the B390, and at 35W the gap grows to about 6%. The unit tested was an engineering sample running at 35W, with retail units expected in the coming weeks.
Dell’s XPS 14 Core Ultra 7 355 offers a refined, well‑built chassis, improved design and solid battery life with a sharp 1200p IPS display, but its 4‑core Xe3 iGPU is noticeably slower and less efficient than the flagship X7 358H. It’s a strong midrange choice for everyday tasks and multimedia at about $1,700, but creators and gamers should consider the higher‑end X7 for better graphics performance, and you’ll miss a MicroSD reader and camera shutter (with some fan noise reported).
Phoronix compares Windows 11 Home and Ubuntu 26.04 on an MSI Prestige 14 Flip Panther Lake laptop (Intel Core Ultra X7 358H with Arc B390). Using the same balanced power profile, the test found near-identical performance between Windows and Linux, though MSI’s Linux power limits were initially conservative relative to Intel’s guidance; Linux remains competitive on Panther Lake with the latest kernel and Mesa drivers across CPU and graphics benchmarks.
Intel’s 18A process introduces Backside Power Delivery Network (BSPDN) along with PowerVia and RibbonFET, freeing front-side real estate and boosting power efficiency, but its ground‑up impact on chip design makes external adoption slow. Industry observers expect wider uptake only later in the decade (around 2027), with 14A‑class nodes a more likely external path, though Intel’s early lead still gives it a competitive edge over rivals like TSMC.
Dell's new XPS 14 posts a record 21 hours 20 minutes of battery life in Tom's Guide's lab test—the longest seen on a Windows laptop—thanks to a Panther Lake-based Core Ultra 7 355, 16GB RAM and a 14-inch LED panel. The entry-level model ($1,699; shipping Feb 19) trails Intel's promised 27 hours but beats the Dell XPS 13 with Snapdragon X Elite and other rivals, signaling Windows endurance has caught up with Apple's MacBooks. Dell says the XPS 14 offers best battery life among Windows laptops, though Apple may respond with future M-series upgrades.
Ars Technica tests the Asus Zenbook Duo UX8407 powered by Intel Core Ultra X9 388H (Panther Lake) and finds a substantial, well-rounded upgrade: strong CPU and GPU performance, notably better efficiency, and solid battery life for a dual-screen laptop. Panther Lake appears to be Intel’s best laptop CPU in years, with Copilot+ support and a clearer, more unified feature set, though supply constraints and the two-screen form factor temper short-term enthusiasm. The long-term question is whether this marks a stable, repeatable turnaround for Intel or a rare standout in a period of ongoing iteration.
Ultrabookreview.com breaks down Intel Panther Lake (Core Ultra Series 3), outlining three sub-lineups (X7/X9 with Arc B390 iGPU for high performance, Ultra 9/7 300H for mainstream, and Ultra 5/7 300 for efficiency) and listing every current laptop built on Panther Lake, from premium X9/X7 models with Arc graphics to mid-range Ultra configurations and high-end dGPUs; it includes high-level performance notes (roughly 10% CPU gains over Lunar Lake, up to 50% multi-thread gains, Arc B390 delivering top GPU performance) and a large, evolving roster of devices across major brands.
Notebookcheck tests Intel’s Panther Lake Core Ultra X9 388H and finds it outperforms Arrow Lake and Zen 5 in both single-core efficiency at low power (approximately 13–15 W total package) and multi-core performance across 20–45 W, while remaining competitive with Apple’s M5 for multi-core work. Panther Lake consolidates the previous Arrow Lake and Lunar Lake generations, delivering strong performance in slim laptops with lower power envelopes and offering a compelling option for 2026 handhelds and thin notebooks.
HotHardware tests a pre‑production Lenovo IdeaPad Pro 5 powered by Intel's 16‑core Core Ultra X9 388H Panther Lake, highlighting an 18A‑process, disaggregated tile design with CPU, GPU, and NPU. In early benchmarks on the premium notebook (16” OLED, 32GB RAM, 1TB), Panther Lake shows strong CPU/GPU/AI performance, improved efficiency, and robust I/O (up to 20 PCIe lanes, Wi‑Fi 7, Thunderbolt 4), though the top 16‑core/12‑Xe3 config remains not retail‑ready. Memory scales up to 128GB with high speeds across DDR5/LPDDR5X variants, and the device delivers solid battery life for a high‑end portable system.
