Geekom GeekBook M16 review: A battery life champion with flaws

In PCMark 10, the GeekBook M16 scores 6,678 points, broken down into 10,031 points for Essentials, 8,496 points for Productivity, and 9,483 points for Digital Content Creation. The overall score is, by design, lower than the individual results due to the internal weighting of test categories. This is a solid, but not outstanding result. Its in-house counterpart, the GeekBook X16 Pro, scores 8,256 points despite having an identical CPU. Even the Lenovo Yoga 9i, which boasts a more energy-efficient Intel Core Ultra 7 258V, manages 7,719 points.

However, the reason for this measurable performance shortfall lies only partly with the RAM. A closer look at the system settings reveals that Geekom keeps the M16 on a very tight leash when it comes to power consumption during everyday use. While the system does briefly ramp up during short bursts of load, the CPU is throttled early during typical productivity tasks to maximize battery life and keep temperatures low within the slim chassis. The GeekBook therefore deliberately sacrifices computing power in the name of efficiency and quiet operation. As a result, the Core Ultra 9 performs closer to a throttled Core Ultra 7.

In the 3DMark CPU profile, the M16 achieves 7,071 points at maximum thread utilization, putting it ahead of the X16 Pro, which scored 6,741 points. Scores across the different thread levels – ranging from 937 points with a single core up to the aforementioned maximum – demonstrate the hybrid architecture’s smooth scaling between performance and efficiency cores.

When it comes to graphics, the downside of the Meteor Lake platform becomes apparent. Time Spy awards the integrated Arc graphics 3,935 total points, of which 3,545 are for pure graphics performance. That’s almost identical to the X16 Pro’s 4,073 points. The Yoga 9i, with its newer Lunar Lake GPU, outperforms it with 4,716 points, despite having half the number of CPU cores.
