I wish one or two of these came from the factory having a 35w TDP, or 50w . Could be anything, just something lower than 65.

64 watts it is then!

well they still dont target a true SFF with those.

guys
AMD Ryzen 3 Pro 4200G
AMD Ryzen 3 Pro 4350G
seems identical.

are those 4ccx vs 2ccx configs ?

TDP are THERMAL solution design power, not electrical power. They are meant as guides for heatsink selection and since it is trivial to design heatsinks capable of handling 65+W in desktop form factors, there is no point bothering with TDPs below 65W even for chips that only draw 35W.

You could Underclock your CPU if you wanted to reduce the TDP, to whatever you wanted.

Set the CPU Multiplier to a smaller value, if your CPU Frequency is 4.5 Ghz then the multiplier would be 45 (probably). Reduce it to as low as you want to go.

The lower-end SKUs are well below 65W average electrical power under stock conditions, the 65W Thermal Design Power is simply because going any lower than 65W for desktop heatsinks yields no meaningful savings in desktop heatsink design and manufacturing costs: a 35W heatsink might shave 5mm on the extruded aluminum heatsink height, which is only 10-20 grams (under $0.05) worth of material.

Mobile chips get multiple fine TDP brackets because cooling solutions are application-specific and a few watts difference can have a substantial impact on design possibilities in heavily space-constrained designs like laptops.
