I’m wanting to build a gaming rig with low TDP.
-
For what I recently read you can't trust the TDP values as such. They're correct but don't take peak power into account. And with good cooling you can keep the peak running quite a long time.
Underclocking a decent system might be the best alternative for low energy consumption.

My guess is a gaming laptop is gong to be your best bet as they are pretty much optimized for power.

Gaming laptop chipsets usually make a lateral move over when motherboard manufacturers incorporate them into desktops.
I got lucky years back when the “pentium m” did this and I’m always looking for that kind of tech.

My current PC GPU is a strix 3080 12gb. At stock, full load it'll draw over 400w. I undervolt (not underclock) mine and get that down to like 330-350 with the same performance. I found that at stock settings, even wth the great cooler on this card, it would get to where it'd start throttling and I'd lose performance. Cooler cards will hold their boost clocks. Less wattage=cooler. Same rules apply for CPU too. But there are limits to that. Cut the power back too far and you'll crash. Like running an engine too lean. Wth electronics, the opposite is true if you run too hard. Too much voltage=higher watrage=more heat. Chips get too hot they either throttle or straight up crash. Takes time finding that balance. No single set of settings as everyone's setup is different. Problem with laptops for this is cooling. They just aren't set up for it for one and the mobile chips do not necessarily =the their PC counterparts.
