Yes and no. Depends on the laptop. Some OEM's artificially limit the TDP of the CPU so the GPU can't work as well as it should. Basically it will throttle. I have a Sony Vaio Pro 11 and Samsung Ativ Book 9, both with an i5-4200U and HD 4400 GPU. The Samsung works like a charm, no throttling whatsoever. The Sony on the other hand, it likes to throttle constantly, and it runs just as cool as the Samsung.
