Why I Am Switching from ASUS ROG SCAR to Lenovo Legion Pro 7
I am writing this post to explain why I decided to move away from ASUS ROG SCAR and switch to the Lenovo Legion Pro 7, despite having used and liked the ROG lineup for a long time.
Main issue with ASUS ROG SCAR
My biggest problem with ASUS ROG SCAR laptops, especially the 2023–2024 models, is the severe CPU power limitation introduced through BIOS updates.
After certain BIOS versions:
CPU power is significantly reduced
The BIOS becomes locked, with no option for the user to control power limits
Micro stutters appear
Synthetic benchmark scores drop noticeably
Real-world power limitation example
In many scenarios:
The GPU runs at around 80% load using approximately 140 W
The CPU is capped at around 65 W
Considering that the laptop’s total power budget is around 240 W, this means:
The CPU is not allowed to use the remaining available power
Total system power draw often peaks at only ~205 W
This results in a clear CPU bottleneck, even though there is unused power headroom.
My personal experience
I owned a ROG SCAR G16 (G634JZ, 2023) and fortunately never updated the BIOS, staying on version 318.
Users who updated to BIOS versions 331–333 widely reported:
Heavy CPU power restrictions
Locked BIOS with no user control
Micro stutters
Lower benchmark and in-game performance
Unfortunately, ASUS has done nothing to address these issues or give users back control.
Concerns about newer ASUS models
This raises serious concerns regarding the ROG SCAR 2025 models:
There is no guarantee that future BIOS updates will not introduce the same power limitations
There is no assurance that performance will remain consistent after updates
The risk of locked BIOS behavior remains
Many users have reported these problems, which significantly reduces confidence in ASUS as a brand.
Why Lenovo Legion Pro 7
When comparing systems with identical or very similar hardware:
ASUS ROG SCAR G16
Lenovo Legion Pro 7
The Legion consistently:
Performs faster
Shows fewer micro stutters
Allows higher and more stable CPU power usage
Avoids aggressive or hidden power restrictions
Conclusion
For these reasons, after selling my ASUS ROG SCAR G16 (G634JZ, 2023), I decided to switch to the Lenovo Legion Pro 7.
This decision is not emotional but purely technical, based on real-world performance, system stability, and hardware control.
