Key Takeaways
1. The Yoga Book 9 14 features the Intel Arrow Lake Core Ultra 7 255H processor, offering significant performance upgrades over the original Yoga Book 9 13.
2. The new CPU can achieve speeds up to twice as fast as the Core Ultra 7 155U in the previous model, with improved graphics performance.
3. Performance may decline by up to 25% during continuous use due to thermal limits and Turbo Boost capabilities.
4. The Yoga Book 9 14 experiences more throttling compared to the Xiaomi RedmiBook Pro 14, which uses the same CPU.
5. Despite throttling concerns, the Yoga Book 9 14 still greatly outperforms its predecessor, making it a notable upgrade.
The latest Yoga Book 9 14 has started shipping, equipped with the cutting-edge Intel Arrow Lake Core Ultra 7 255H processor. This is a notable upgrade from the original Yoga Book 9 13, which was limited to Core U-series processors. The new CPU boasts speeds that can reach up to twice as fast as the Core Ultra 7 155U found in the previous 13-inch version, and the graphics performance shows even more significant improvements.
Performance Considerations
However, it’s important to note that “up to” is a key term here. Our review highlights that the H-series CPU might be more than what the Yoga Book 9 14 can effectively manage. For instance, while running CineBench R15 xT in a continuous loop, we observed that the processor’s performance could decline by as much as 25% over time. This is likely caused by limited Turbo Boost capabilities or thermal limits, whereas the older 13-inch Yoga Book 9 exhibited minimal throttling even under similar testing conditions. Interestingly, the Xiaomi RedmiBook Pro 14, which uses the same CPU as the Yoga Book 9 14, demonstrated less throttling compared to our model, as illustrated in the graph below.
Throttling Insights
The throttling observed in our Core Ultra 7 255H setup raises concerns that a similar situation might arise with the more expensive Core Ultra 9 285H variant. As such, potential buyers might want to think about avoiding the pricier Core Ultra 9 option, as the performance differences between the two CPUs are expected to be quite small. Nonetheless, it’s still worth mentioning that the Yoga Book 9 14 significantly outperforms its older versions by a wide margin, irrespective of any throttling issues encountered.
