If you underclock the Threadripper to get a score of ~27k, then how much power will it use? I wouldn't be surprised if it was roughly equal to 90W, or even lower.

The stock configurations for a lot of desktop chips is to get the maximum performance at the expense of power, especially for things like these Threadripper series which are explicitly aimed at maximum performance. Often even drastically reducing power usage only gives modest performance penalties.

Yes, cutting power targets of a (Desktop) Ryzen to 65W or 90W reduces performance to around 50% or 80% in some benchmarks, iirc. Likely a good tradeoff in many scenarios.

I also run an RTX 3900 GPU at 60% power for 80-90% performance. It's a noticeable decrease in requisite cooling.

Yeah I am definitely not a fan of Intel/AMD/and even Nvidia who will completely push power to stupid levels just to get less than an extra 10% performance

Gamers Nexus did a video earlier this year comparing the 7950x at different eco modes and they found that putting the 7950x at a 105 watt eco made drop the performance around 5% but shaved almost 100 watts off of power. heres the link to the video https://www.youtube.com/watch?v=W6aKQ-eBFk0

I know why these companies do it and im lucky electricity isnt too expensive in my area but i rather shave 100 + watts of heat being dumped into my room (especially in the summer months)
