A new BIOS update, specifically version 319, has been getting reports of actually decreasing performance of games being played on the ASUS ROG Ally. Brought to our attention by Fan the Deck, who also tested and confirmed this, the new BIOS update seems to cut performance in games up to 33% on higher clock speeds (Turbo Mode).
This was also reported on The Verge's updated review of the ROG Ally where Sean Hollister notes that:
I also saw my framerates dip by up to 20 percent, seemingly because newer BIOS revisions don’t maintain the same clockspeeds. "

While we haven't personally tested, The Phawx posted a YouTube video with his findings showing that this seems to be true. He shows that at 25W, compared to the last BIOS update (317), Cyberpunk 2077 goes from 49.1 average FPS to 41.6, Arkham Knight from 72.4 to 71, and Red Dead 2 goes from 59.5 to 57.3. It also shows that some 10W (Silent Mode) clocks don't change as much or get a little better (like Arkham Knight at 10W going from 28.2 to 29.7).
If you haven't updated yet, it is advised not to, but if you already have, it is safer to leave for now. Hopefully, this is an error on ASUS's part and it will be corrected in a new update so we can get our performance back!

I was actually doing some benchmarking of the Random algorithm and had my benchmarks go slightly up after the BIOS update that forced itself. I was getting around 3850 H/s prior to the update but it hit 3960.3 H/s after.
Maybe they are making some changes with the new updates! This is good to see. I believe there was a new update recently.
Honestly, Asus has a bios problem, I have a g531gw that I installed a bios update on and now it's literally unusable for gaming. When the 9750h turbos the heat cranks up to 97 degrees Celsius. It's now the heaviest basic windows PC I have ever owned.
I do know they are looking into it, so I hope something if fixed and comes from it. Crossing my fingers!
Is this not an over reactiin of a loss of a few frames doe potential better battery life?
It depends. I am hearing around maybe a 10-15 min battery life increase over up to a 33% performance loss. This is something I haven't personally tested, but I think reporting the loss is definitely worth noting.
Nothing in the article shows anywhere close to a 33% drop. Where is the evidence for this?
Nothing in the article shows anywhere close to a 33% drop. Where is the evidence for this? Also the numbers you referenced aren't near to what you've said. You referenced someone else's comment that said up to 20% but the fps losses you posted are even less by quite some margin.
