I know the AMD Ryzen 7000 series have a 105 W Eco mode and 65 W Eco mode. The fairly new 8700G APU (desktop CPU) defaults to 65 W TDP but can be configured to 45 W. How would I get a desktop CPU to get down to, say, 35 W or less? The AMD Ryzen Mobile variants like 8845HS is 45 W default but configurable to 35-54 W. It's a desktop CPU but may only be available to OEMs and not retail end users like you or me (sadly). Same with the very new Ryzen 7 Pro 8700GE which is 35 W desktop chip with much of the same capabilities of the full power 8700G that we can buy retail.

It seems that a lot of these "Pro" chips are available only to OEMs and not retail buyers, hence why if we want those CPUs we have to buy a pre-built mini PC. I'd prefer to have them available through retail channels like Amazon/Newegg/Microcenter so enthusiasts can buy one and pop it in our own AM5 motherboard and case of our choosing.

Anyway, do you know how we can buy a full power desktop CPU and configure it down to 35 W or less? I don't know if BIOS/UEFI settings allow lowering the power limits that much -- it would have to be very custom settings and not built-in "Eco" modes.

It should be a bit less throughput, since lowering power limits usually lowers clock speeds and single-core and all-core boost clock speeds across the board to stay under those PL1/PL2 power limits.

It's a bit less throughput but with the benefit of less power consumption and heat. But honestly, I'd prefer to just get a lower TDP chip to begin with rather than neutering a full power desktop chip, especially if the low TDP chip is cheaper. If it's the same price then no big deal.

I just really want a nice 8 Core/16 Thread 35 Watt TDP chip for WCG to replace my old 4 Core/4 Thread CPUs that consume like 78 Watts from the wall

Yeah, it's pretty great. Check out this article from a couple months ago:

Leaked AMD Ryzen 7 8700GE 35W desktop Zen 4 A...ormance at half the power

It uses about half the power but you don't get half the performance -- it's a bit more.

I don't see measurements of power consumption for the entire systems, just looking at the TDP and saying it uses 50%, is complete nonsense, 35W is not even 50% of 65W and the 35W chip is likely more often at that limit than the 65W chip. And than of course you want to know the power consumption of the entire system and not just the CPU cores.
