Not really. The GPU is "hard coded" to lower performance when the laptop is not plugged into the AC outlet. This is to conserve power and also because the a lithium ion battery can only provide so much power at once. For example, say the battery can only provide at most 90w of power, but with the CPU and GPU running at full power, the laptop needs 120w of power. If the battery cannot provide enough power, then the laptop would freeze or crash.
