Tried reflashing bios 2 times? Maybe it's not the case anymore but worth a try. Some bios flashing might require to flash twice if something went really bananas. This being said, it sounds like it's something firmware level or hardware. You pretty much did everything you could at a software level. One last thing would be a clean windows install together with blocking windows from installing drivers and such. Installing all drivers directly from Lenovo support while being sure windows hasn't poisoned any device.

Damn, I pulled the trigger. No clue if i should be happy or sad 🤐

weird ...G-Sync should lead to uqual or better gaming experience than adaptive sync. Then again, it might just be some stupid software implement where if you don't turn on adaptive sync G-Sync does not really turn on. If you turn off adaptive sync and turn on g-sync, do you get the same performance you get with both off?

i've had Kryonaut and TFX pump out but solved with SYY 157. Kryonaut actually pumped after long time (although laptop was brand new), TFX after a few days (but laptop was old already). SYY is still working after months and was applied when the laptop was old already. (referring to my experience on my current clevo p650hp6 if it matters)

Yeah, on a workstation-class laptop this is quite ridiculous. As if 100% cpu load scenarios wouldn't be possible or even frequent. Not even commenting on the GPU side of things where a 3080ti is almost equivalent to a 3070ti due to power throttling. The real difference is usually in the 300-600€ you get charged for it.

Jarrod review of the legion 7i also showed similar bugs: using Lenovo gpu drivers led to everything behaving perfectly while updating Nvidia drivers manually led to USB-C ports not working as video output. I guess this means that they either tweaked gpu drivers (maybe even just to iron out nVidia bugs) or that the latest nVidia drivers have some weird behavior in specific scenarios. Advanced Optimus is still fairly recent so both scenarios are actually possible in my opinion. Also, with advanced Optimus you should not need to go for the "use dGPU" only. As far as I understood it's identical to the old Optimus (known as MS-Hybrid) with the exception that the current implementation (advanced Optimus) added a mux switch to bypass di iGPU. Old Optimus was in fact forcing the traffic to the iGPU even when using the dGPU. This being said, I think that having the Intel control panel working or not shouldn't necessarily be related on the advanced Optimus working properly or not. I would say that a good implementation should allow both control panels to work even the settings of each panel only apply to their associated gpu. Overall, i would advise you to make some testing with Lenovo gpu drivers. In this way should have a clear answer of how the system should behave when everything works properly. Considering that the latest nVidia drivers cause weird bugs here and there I wouldn't be surprised if what you are describing is just unexpeteced behavior. EDIT: what's your opinion on your signature razer blade VS this legion?

I 100% agree. And considering how much more you can get out of top notch cpus with such apps I really hope the support won't ever stop. I would even be willing to pay decent money since it's no different than paying for a better piece of hardware for me. In fact, I actually wonder why no producer goes a step ahead and introduces an automatic routine to produce an optimized Throttlestop/XTU/bios profile for some bucks. This is usually worth more than a cpu upgrade. Maybe it's just my nerd attitude but I really wonder why.

Unclewebb is still quite active on the TPU forum so we might get an answer over there. Considering how many things he added since I got my 7820hk, I'm faithful. To be fair XTU has also gotten better. It went from utter useless to an almost usable alternative. EDIT: damn, those 13900K multithread scores almost make me want to wait another year 😕

I've found some people that did it while lurking around over reddit/youtube/throttlestop threads here and there. Not many though. However, I can't really remember exactly where I found stuff so I can't pinpoint everyone I stumbled upon in the last couple of weeks. One guy was certainly talking about how undervolting the legion i7 (lenovo legion subreddit) boosted his gaming performance consistency by (especially) lowering his stuttering. If I'll pull the trigger on a legion i7 in the next few days I'll certainly do that.

Has anyone of you benchmarked (or sort of) the igpu of the HX series? How wonder how much slower it is when compared to the iris of the H series?

8 hours is definitely good and certainly not an issue for such a laptop. This is also the reason why I'm prefering Intel to AMD for this generation (and when talking of 15-17" powerhouses). However, almost every in depth review I found showed a 30 to 100% improvement in battery life when opting for the AMD counterpart. Many reviews even showed that AMD gets better performance when operated on battery due to Intel being TDP throttled (this is my assumption as I don't see any other reason). This is also fairly reasonable to assume since going for the 80-100W spot would drain a 99Wh battery in way less than a single hour. However I also think that AMD will switch to the big little architecture in a few years. It just seems better even with this first iteration. I think that after a couple of iterations there should also be huge gains in scalability within the low TDP ranges.

I completely agree as I lean towards Intel. However, no matter the undervolt/optimization: it seems like under 30-40W AMD just wins in terms of efficiency. This is also completely reasonable if we think that Intel scales nicely from 40 to 120W where AMD is super bad. It is quite legit that AMD shows more scaling margin in the idle-browsing TDP levels (5-30W). And this is also the reason why there is no competition in battery life usually. Curiously, Intel also looks more efficient in single core turbo boosted tasks as AMD probably pushed a bit over the limit to compensate for the low single core performance. There are a few reviews by jarrod and some others that actually show nice scaling charts (e.g. image below)

Yeah, fair enough. I was stupidly thinking of any high level laptop including gaming version and not workstation-class only. So let's make it a different question: If a 6900hx workstation-class was actually available, would it make more sense over the 12900hx options? I'm always attracted by raw power no matter what and lean towards Intel setups but I wonder if >80W load cases arejust so unbearable (fan noise and whatever) that AMD is simply superior. Feels like many people, me included, just lean towards Intel setups even when amd is available but I have no clue if I have a real reason for my preference or not. Current laptop TDPs are just getting out of hand and maybe it's just something I shouldn't consider. Actually, does anyone know if Dell has any plans of introducing amd-based versions?

If that's the typical use case why not simply opt for a 6900hx which is way more efficient than Alder lake when below 30W and has close performance in the 40-70W range. If someone plans to not ever exceed the 70-80W for cpu only loads you basically get better thermals, noise and battery life at a lower price if you just pick up an amd laptop. Or am I missing something?

I think I'll pull the trigger on the 12800hx - 3070ti. Much more affordable and basically same performance. Should also be quieter and cooler. Might even consider the 6900hx 6850m xt since it's same price but I'm not fully convinced with the 6900hx. Not being sure to have the option to undervolt the 12800hx is the main reason I'm still considering the amd version honestly. Undervolting my actual 7820hk has done wonders and losing this possibility would piss me off for such an expensive laptop. Both versions should be below 3k€ anyway. EDIT: undervolting is actually possible as reported in the mash it review so I might pull the trigger in the next days. Let's see if I'm strong enough to resist or not😬
