Ok, here is the logic behind the limits.

15/18/25 are manufacturer claims by Ayaneo. Ayaneo is the only
manufacturer that made devices prior to the new ones that support 30W
limits.

28W is used for GPD because their devices are very portable and 30W
makes e.g. the bottom pan of Win Minis too hot. It is also used for
the Ayaneo 2/Sui/OPI, because these devices have a fullwidth glass
front that is used for heat dissipation. So the screen gets very hot.

The rest of the devices use 30W.

As for which software each OEM has. GPD: GPD does not ship first party
software for TDP controls. They collaborate with an independent
developer developing "Motion Assistant", which they also ship with
their devices and features a TDP slider. Ayaneo uses Ayaspace, which
is backed by Ryzenadj, and they give slider control to users,
typically with a 30W limit. They also use userspace customizable
presets for some default e.g. 20W profiles. Onexplayer has oxpconsole
with a slider as well that does 30W usually. Ayn exited the market on
WIndows handhelds, no software. OPI, you'd need to ask Phil but this
would be the primary driver for it. There is no alternative that can
also go to SteamOS.

The reasoning behind the profiles is simple. 8W is power savings
territory. Going below can yield around 1W more, but the performance
degradation is not worth it. 15W is a good sweetspot for 30W
processors. Then, 25W is good for these devices as they saturate above
22ish Watts. We could even go lower to 20W, as Lenovo did on the
original Go. But their newer devices use higher AC values.

For their boost clocks, sPPT is set to around 2W higher than spl (what
is it called now?) to give a small boost. fPPT is set to a reasonable
amount for that device class and interpolated vs spl. The exception is
low-power where we do not want boost
