I'm still waiting on my 6800U device to arrive, but I've been digging into this.

As far as "auto" TDP tools go, feature-wise, none are at the same level as the batch file unfortunately. That said, I imagine this functionality will be rolling into things like ProjectSBC's control panel and HandheldCompanion over time.

As far as what's out there now and what I hope will get better AutoTDP support:

• MotionAssistant: Has automatic TDP based on modifying GPU throughput (not CPU, as far as I can tell at the moment).

• Personally, I'd rather avoid MA since it's 3rd party (but bundled with GDP devices) and not open source. It's distributed on a Chinese website and then linked more broadly via Discord for download, which in addition to being not great in general, can make it very hard to know if you're on a recent or the latest version.

• AYANEO Smart TDP: Similar to MA with similar issues (can get wonky when GPU is not the bottleneck and there is sufficient power, ie. emulation)

• Also not open source, but at least 1st-party. If it came on my device, I guess I might consider using it but I'd still prefer an open source tool to be able to review. UX is decent.

• ProjectSBC's Control Panel v2: Not yet automatic, supports manual TDP modification.

• Unfortunately this code seems pretty thrown together and wouldn't be my go-to depending on how it evolves.

• HandheldCompanion: Not yet automatic, supports manual TDP modification.

• Actually, at the moment, my preferred choice if it ends up getting support for automatic TDP. The code seems fairly thorough, includes links to references for (some of) the magic numbers used for memory modification. UX is also fairly good.

• Ciphray.bat's AUTOTDP: Being the most featureful is the strongest point here -- even including things like undervolting, which personally I'd separate into a different tool.

• The UX is quite poor of course, being batch files. The usage of magic numbers has a complete lack of documentation and tools thrown together in a zip file without any version history is relatively concerning (especially as these tools require administrative rights to load the PCI read/write drivers).

• Edit: Not trying to bash this too much here, it's just not something I would want to place a lot of trust in. I've seen Ciphray on Discord and he seems to be knowledgeable on the area of power management of these devices, but the tool itself leaves much to be desired.

All that is to say, for now, the only tool I personally would use right now for automatic adjustment is AYANEO's Smart TDP, but only because it's 1st party and included on the device. It's also not perfect so I might choose not to use any tool at all for some time and just wait for either a better tool to come along or for HandheldCompanion to get a really awesome update.

Honestly, I considered (and began) porting Ciphray's batch file to Python. But without a device to test on right now and honestly not a lot of time, it's on hold.
