The process I use to determine the power limit (TDP) the GPU actually runs at is to simply run a GPU workload and monitor the results – like so: For example, the above RTX 3080 reports a maximum graphics power of 130W, but dynamic boost allows it to run at 150W when the CPU isn’t in use. The actual value can of course vary based on dynamic boost though, so I recommend actually testing and confirming. This will show you the “Maximum Graphics Power” value, in the below example this laptop is 130W. Unfortunately, in most cases the power limit is not specified on the spec sheet, so how can you find out? Let’s take a look at how you can easily check GPU TDP on a laptop, and what you can do to find out for a laptop you aren’t able to test.įor a laptop you have access to What does software report?Īfter a recent Nvidia driver update, you can open the Nvidia control panel and select Help from the top bar, then system information. ![]() ![]() Performance will vary based on the power limit of the GPU. Two laptops with the same graphics inside may not perform the same.
