| The HP EliteBook X G2i with Intel Panther Lake |
When Intel took the stage at CES 2026 to unveil its Panther Lake architecture, the company made a bold claim: the new Intel Core Ultra 300 series would finally end the trade-off between battery life and raw performance. Intel promised that its new 18A process would deliver the same power efficiency as the beloved Lunar Lake chips, but with a significant boost in power.
Months later, that promise has been put to the test. After extensive benchmarking of the new HP EliteBook X G2i, the results are in, and it appears Intel has delivered exactly what it promised.
The Test Subjects: A Direct Generational Comparison
To truly understand the progress made, we need to look at two nearly identical machines. The new HP EliteBook X G2i is a 14-inch premium business laptop powered by the Intel Core Ultra 7 356H—a 16-core CPU built on the new Panther Lake platform. It features a sharp WUXGA (1,920 x 1,200) IPS screen and a 68 Wh battery.
This setup provides a perfect baseline for comparison against its predecessor, the HP EliteBook X G1i. That older model features the exact same screen resolution, chassis design, and battery capacity, but runs on the older Intel Lunar Lake processor, the Core Ultra 7 268V, which is an 8-core chip.
Battery Life: Efficiency Without Compromise
The primary concern with any generational performance bump is whether it comes at the cost of battery life. According to detailed testing, the answer is a resounding no.
In direct comparisons, the older EliteBook X G1i does consume slightly less power when idling. However, in real-world usage, the difference is negligible. During a Wi-Fi/websurfing test at a standard brightness of 150 cd/m², the older G1i achieved 18.5 hours of runtime. The new Panther Lake-powered EliteBook X G2i wasn't far behind, topping out at nearly 18 hours.
This confirms that Intel has successfully maintained the legendary efficiency of the Lunar Lake series while upgrading the silicon.

Performance: A Massive 32% Leap
While the battery life remains virtually unchanged, the performance tells a completely different story. The EliteBook X G2i doesn't just inch past its predecessor; it sprints ahead.
Benchmarks show that the new Panther Lake model outperforms the older Lunar Lake version by approximately 32 percent. This is a massive generational leap for an ultraportable business laptop. It means users no longer have to choose the heavier AMD variant (like the older EliteBook X G1a) just to get enough processing power for demanding workflows.
For business professionals, developers, and power users, the EliteBook X G2i represents the "Goldilocks" solution. It offers the portability of a lightweight ultrabook (around 1.2 kg), the battery life to last a full transcontinental flight, and the CPU muscle to handle heavy multitasking, data analysis, and software compilation without stuttering.

The Verdict: The Ultrabook Dilemma is Over
For years, laptop buyers have been forced to compromise. If you wanted a laptop that lasted all day, you had to accept slower performance. If you wanted speed, you had to carry a heavy brick and a charger.
The HP EliteBook X G2i, powered by Intel Panther Lake, signals the end of that era. By delivering a 32% performance boost with identical battery life, Intel has officially closed the gap. The Panther Lake architecture proves that you can have the efficiency of a thin-and-light and the power of a workstation in the same machine.
