Just curious.
When I looked at the 15W and 25W AMD mobile Ryzen U variants implemented,
where do the OEMs show it is the 15W ceiling limit variant (not necessarily even default 15W TDP behaviour) on the branding as this would be restricted to 15W due to internal thermal designs/etc or 25+W for those without restrictions that changes performance and battery life?
The notebook site makes mention of the difference (as they do with MX150), but there seems to be nothing from the OEM showing it as 15W default/15W configured, or the 25W ones that exists and so creating confusion for consumers.
Example of 15W configured option for 2500U with Swift 3 explained by notebook:
Acer has set the configurable TDP to 15 watts, as evidenced by HWinfo's analysis during Cinebench and stress tests and the assignment of Intel's 15-watt chips to the same chassis
Lenovo above 25W not as efficient :

I can no longer find 2500U on their site, but retailers show no indicators of what spec it is in nor do AMD.
Same can be said with 2700U on Lenovo site, which may be replacing the 2500U *shrug*
Acer Swift 15W ceiling limit efficient:

Default 15W unfortunately means little when one also gives a cTDP of 12W-25W to OEMs with TDP envelope control.
AMD on their site note the APU as 'cTDP' with a range of 12W to 25W but that is it; meaning then configurable by OEMs (consumers may not even perceive the context of cTDP) but with such a range it will have an impact on consumers in multiple ways.
For reference it is also branded by AMD as a default 15W component, but that ignores what OEMs can do with cTDP behaviour even with 15W.
Importantly though even AMD do not show TDP implemented by the OEM on their own site where you can click on the OEM model under the 2500U section, even when it is 25W unrestricted.
Unfortunately then consumers could assume they are 15W, 12W, or dynamic and flexible-efficient and can range between 12W to 25W (they are not behaving that way though as an OEM product), let alone how this also affects reviews and benchmarks.
Click see prices for the specific OEM model then details:

Point is this comes back to my previous post #47 and it is far from clear for consumers.
Nvidia is not sneaking this in, comes back to OEMs want greater flexibility to design and select an envelope for a model with different ergonomics/performance/battery life, but IHV need to ensure it is clear for consumers.
It is a trap that many of the IHVs are going to fall into in some way IMO.
