Is there any way to safely increase the voltage for a laptop GPU?
I own an ASUS TUF Gaming F15 FX507ZI equipped with an RTX 4070.
I was shocked to discover that my GPU is capped at around 100 watts, while it's listed as a 140-watt unit.
Cyberpunk consumes 70-80 watts and Starfield uses 90-100 watts.
This helps explain why the 4070 underperforms and consistently receives poor reviews.
Could there be anything I can do? The extra 40 watts would significantly boost its capabilities, and I feel like I was misled.
On NVIDIA's site there isn't a 140W listing for the 4070 model—

115W is the highest available.
Initially, the power limits for notebook GPUs can be set across a broad spectrum by laptop makers, allowing flexibility in cooling options. High TDP claims aren't particularly crucial because the RTX 4070 Laptop operating at 105 Watts will deliver comparable gaming performance to the advertised 140 Watts model. The same applies to other recent RTX 40 series laptops. Nvidia presents a considerable range of performance from 35 to 115 Watts, including up to 25 Dynamic Boost, for models such as the RTX 4070, RTX 4060, and the RTX 4050 laptop variants. This indicates that all three laptop GPUs can handle up to 140 Watts. That adds an extra 25 Watts from the processor through Dynamic Boost. These variations are significant, and I've observed situations where an RTX 4070 GPU running at just 35 Watts easily surpasses an RTX 4050 Laptop at 65 Watts. However, Nvidia has noted that actual power usage varies with the workload. Some people might be confused by the RTX 4070 being listed as 140 Watts on premium laptops, but it only reaches this level under specific conditions and is capped at a maximum of 100 Watts during gaming.

I'm using 2k or 4k through a monitor and DLSS, which seems to work well. The frustration comes from the 3070 140-watt GPU struggling with Cyberpunk at 1080p, maxing out around 140 watts. I'm playing Cyberpunk in 2k at high settings without ray tracing, achieving 100-120 fps with DLSS. I rarely exceed 98 watts.
When adjusting or modifying the power settings and voltage for these chips, keep in mind they are mobile versions, and laptops generally offer limited flexibility. What are the temperature readings for gaming on your laptop?
12700h hits around 85c during gameplay. The GPU stays under 70c all the time.
