Asus ROG Zephyrus Duo GX651 Review: A Dazzling Dual-Screen Beast With a Sky-High Price

Asus ROG Zephyrus Duo GX651 Review Verdict: A Unique Dual-Screen Gaming Laptop With Big Strengths and a Few Costly Trade-Offs

The Asus ROG Zephyrus Duo GX651 is one of the most distinctive gaming laptops available, and its biggest advantage is immediately clear: the dual-screen design is more useful than ever. While this new version gives up some performance compared to the 2023 model, it makes a strong case for itself with a smoother multitasking experience, improved battery life, and a more polished overall concept.

Asus clearly knows how to build dual-screen laptops. The two identical displays make everyday productivity feel seamless, whether you are gaming while monitoring chats, editing content with extra tool panels, managing multiple documents, or simply keeping apps open without constantly switching windows. The experience feels refined rather than experimental, which is important for a premium device in this class.

The improved battery life is another major win. Dual-screen laptops are not usually known for long runtimes, but the Zephyrus Duo GX651 performs much better in this area than expected. That makes it more practical for creators, professionals, and gamers who want a powerful portable machine without being tied to a power outlet all day.

The Asus Pen 3.0 also works very well. During testing, it delivered a reliable and accurate input experience, making the laptop even more appealing for digital artists, designers, editors, and users who want more precision when working on the secondary display.

Gaming performance remains excellent. With the RTX 5090, the Asus ROG Zephyrus Duo GX651 can handle demanding modern games at the highest graphics settings without trouble. It is built for high-end gaming, and it delivers the kind of smooth performance buyers expect from a flagship ROG laptop. When running at maximum performance, the fans are clearly audible, but that is not surprising given the powerful hardware inside. Users who prefer a quieter experience can switch to lower performance modes, which help reduce fan noise.

However, the laptop is not without weaknesses, and some of them are surprising considering its premium price. One of the biggest concerns is the new Intel Panther Lake processor. Its stronger focus on efficiency helps with battery life, but it also leads to relatively modest multi-core performance compared to what some users might expect from such an expensive workstation-class gaming laptop.

Memory is another limitation. Asus uses soldered RAM, which means the maximum capacity is limited to 64 GB. That will be enough for many gamers and creators, but this type of specialized dual-screen laptop could benefit from more memory. The Core Ultra 9 386H can technically be paired with regular SO-DIMM modules, which would allow configurations of up to 128 GB, but Asus did not choose that route here.

The absence of Thunderbolt 5 is also disappointing. For a high-end laptop aimed at gamers, creators, and power users, the latest connectivity standard would have made the device more future-proof, especially for external storage, docks, displays, and professional accessories.

Storage options are better. The laptop comes with a fast PCIe 5.0 SSD, and Asus also includes a second M.2 slot with PCIe 4.0 support. That gives users a convenient upgrade path if they need more space for games, video projects, creative assets, or large work files.

Overall, the Asus ROG Zephyrus Duo GX651 is a fascinating and highly capable dual-screen gaming laptop. Its multitasking experience is excellent, the displays are practical, the gaming performance is very strong, and the battery life is much improved. At the same time, the lower multi-core performance, soldered memory, 64 GB RAM limit, and missing Thunderbolt 5 hold it back from being the perfect premium powerhouse.

For users who want a one-of-a-kind gaming laptop with serious multitasking potential, the Asus ROG Zephyrus Duo GX651 remains an impressive choice. But buyers who need maximum CPU performance, more upgrade flexibility, or the latest connectivity should carefully consider these compromises before making a decision.
