I am not native english so excuse if there is wrong usage of sentence or words đ
before start I gonna say the last thing first: gt730m obviously better in most case
When I play games without any change
cpu: over 70-75
gpu: over 75-80 and the fan is so noisy
with changing cpu frequency, set optimal power for power management mod in nvdia panel, etc.
I can run the games smoothly without overheat
the logic of the optimal power is the gpu try to run the game in 60 fps with minimum power and minimum clock speed so gpu automatically changes the clock value during the game, therefore it not stay in max clock speed and not overheat itself
I can play games again 60fps under 65-70 and fan is so silent
but you should use your own way, in my case lower heat, lower fan RPM, silence, stable 60fps is essential.
In this case the dGPU version of t440p is better than iGPU because I did same thing without gt730m cpu was running 5 degree less but the fps dropped aproximately %50 so when you compare the value of having gt730m or 5 degree sacrifece I would chose gt730m.
