In this episode of the Windows Central Podcast, Daniel Rubino and Zac Bowden regroup following a week of extensive hands-on hardware testing and benchmarking. The central focus is the initial review wave for the Surface Laptop Ultra and the broader Nvidia RTX Spark mobile platform.

Zac details his full review of the Surface Laptop Ultra, highlighting its MacBook-inspired design improvements, haptic touchpad, outstanding audio, sleep battery efficiency, and magnetic USB-C connector—while contrasting its 2,000-nit Mini-LED display against competing Tandem OLED panels. Daniel shares first impressions of two rival RTX Spark flagships: the ultralight 3.9 lb ASUS ProArt P16 and the robust HP OmniBook Ultra 16.

The hosts dig into real-world local AI and agentic workflows (including tests with Hermes Agent and local LLMs), explain the critical architectural advantage of configurable unified memory allocations for GPUs, discuss gaming performance with DLSS/frame gen, and showcase the newly launched ASUS ROG Xbox Ally X20 handheld console bundle featuring XREAL AR glasses.
