Thank you for the honest feedback. Since my limited performance requirements (really just the old 4x games), my main concern besides standard battery life, etc. is the heat concerns and thus longevity. This thread in particular addreses the main intel concerns I have with no real resolution. Again 155H used as example. > [@AMD & Intel reduce power consumption in order to increase battery life/reduce fan noise (TDP, efficiency mode)](https://community.frame.work/t/amd-intel-reduce-power-consumption-in-order-to-increase-battery-life-reduce-fan-noise-tdp-efficiency-mode/59482/27): > > It’s an Intel system. XTU is not supported on mobile core ultra. You get an error of something like, “tried to install on unsupported hardware”. XTU also isn’t the BIOS. Intel Undervolt, from my understanding, works on the same premise as the Throttle Stop utility I mentioned above. Throttle Stop however doesn’t allow for the usual tuning like on older hardware; those options are greyed out and not selectable. It allows for disabling boost entirely or adjustment of “Speedshift EPP”. Undervol… There are some benchmarks out there that basically state Ryzen AI high end \>\> Intel core = 7x40u on linux at least. Other more traditional benchmarks support intel being a essentially equivalent to 7x40u. The one linux one that is being referenced a lot, even by framework X account seems to indicate the heat is killing the performance. Again, not so worried I think 125h / 7640u would be great for me, but IDK what to get. I keep flip flopping. > **[21-Way Intel Core / AMD Ryzen Linux Laptop Comparison On Ubuntu 25.04 Review](https://t.co/O4kjfLmSdu)** > > As part of fresh re-testing of existing laptops on-hand given the recent release of Ubuntu 25.04 and then also recent Linux reviews of some interesting models like the Framework Laptop 13 with AMD Strix Point and the Lenovo ThinkPad X1 Carbon Gen 13... Supposedly, (from my research) neither will support regedits to add option for s3 suspend. Intel supposedly was able to do this historically, not sure about ultra 125h specifically, but generally intel is much more in favor of modern suspend and ryzen 7x40 supports, but NOT for U series processors. This is just trivia, since I will likely just use hibernate direct (current use w10 xps and thinkpad) or suspend then hibernate with w11 ltsc (planned OS). Hopefully 32-48 gb paired ram doesn’t result in crazy hibernate wake times. My current 16gb ddr4 laptops seemingly take as long to hibernate wake vs cold boot wake. --- _[View the full topic](https://community.frame.work/t/7040u-vs-125h-stability/69633)._
