You're evaluating a PC build with a focus on power efficiency. The 7900 series offers flexibility, and you're weighing the 7900x against the 7900 for cooling and cost savings. Eco Mode can help manage TDPs, potentially allowing your 7900x to run closer to its 65-watt limit. Regarding performance, the higher-binned silicon in the 7900x might offer a slight edge. As for Eco Mode, it can be configured in BIOS or Ryzen Master, though the exact differences between the two methods aren't always clear. Since you plan to dual boot into Arch Linux, adjusting TDP settings globally would likely require BIOS changes.
I've worked with a 7950x using PBO's eco mode, which sets TDP limits. For example, the 7950x I built had 65W, 105W, and 180W (though I can't verify details since it's production). It runs on the 105W profile and draws up to 120W per hwmonitor. Likely, a factory 7900 or a 7900x in eco mode at 65W TDP would stay under 90W.
Operates on Windows Server 2019 using an Asus x670 ATX board. The chipset driver isn't available in Server 2019 yet, but it hasn't caused any issues. I had to enable the Performance power plan since the app didn’t switch to P states, so it consistently runs at a 5.5GHz frequency. The environment is air-conditioned, so it works fine. It was chosen because the app needs top single-thread speed and enough multithreading to support several users, improving performance compared to the previous dual Xeon setup.
