Thanks for another nice one Terk! Looking forward to your GEEK comparison. I did some (fairly) extensive comparisons with AYANEO 2, A1, and the Deck which wasn't fun but I think it was worthwhile.

What's very interesting is that Zen 3+ is already supposed to do this. AMD specifically talked about how they added HW support to very quickly (like 1ms, many times faster than AutoTDP) sleep and resume parts of the SoC when load demands it. And in my experience, it works, when not at target performance, I can see 40-60W from my 6900HX, but in simple applications that max out target performance, I see anywhere from 15-35W from the 6900HX, with the GPU and CPU spending most of their time at base clocks (presumably sleeping?), and GPU boost over 1000MHz being a rarity. Of course, I'm testing on a totally different platform, SoC, firmware, unlocked chip, etc.... than your 6800U handheld, so don't take what I say as gospel. And of course, AutoTDP is still a great option for the Zen 2 based Steam Deck, which probably doesn't have the HW power saving features Zen 3+ does. And as always awesome content, keep up the great work!

The difference is that autoTDP boosts to a performance target, ie framerate. AMDs firmware boosts as you describe and I show, but it boosts to maximize performance. AMD has no visibility to framerate at the firmware level.

@@TheTerk That's not what I'm seeing. I tested a V-Sync cap at 30/60/120/unlimited FPS on a 4K120Hz display, and the results are consistent: reaching the target performance results in reduced power consumption and more time spent at base clock/sleeping. Granted, different games, chips, firmware, etc.... so the data is not exactly 1:1.

Is there any reason why anytime I open AutoBat it has the processor set to 1577Mhz regardless of my TDP? I have less than expected performance in D2 at 18W and I wonder if AutoBat isn’t doing what it’s supposed to.
