> However this method does not work for server and workstation CPUs, because these have already the highest TDP that is possible with the current cooling solutions, so in servers and workstations the bad Intel MT performance is much more visible
I disagree on this point. I would say this problem is much more critical on Intel's desktop platform than their workstation platform. Xeon Sapphire Rapids is actually very easy to cool, even on air, thanks to the CPU having a much larger surface to dissipate heat than their desktop equivalent.
I have Xeon w9-3495X, and while power consumption is one of its weakest points, it stays under 60°C with water cooling while I pump 500W into it (25°C ambient), of which I see between +30% to +50% gain in multithreaded performance over the default power limit. (Golden Cove needs around ~10W per core, so the default 350W/56c = 6.25W is way below its performance curve.) Noctua has also shown that they're able to achieve ~700W on U12S DX-4677[1] on this platform.
