Hi everyone,

I switched from my EliteBook x360 1030 G3 with Intel i5 8350u (Undervoltable) to my new Dell Inspiron 13 7306 with i7 1165G7. And to make a long story short this isn't worth it right now. I can undervolt my 8350u which makes it possible to run it smooth at 27w and temps staying in the 80is. Now with my new one I can only run at 20w to get it in the same temperature area. Elitebook and Inspiron aren't in the same category or priceclass but thats not the point right now.

I tried cinebench and some other tools and my new TikerLake CPU is at the same scores than my old i5 CPU (For example 700 Point on Cinebench R15 Multi, middled in 10 runs). This is very good for my old i5 which is nearly 3 years old but very poor for my new i7. And its also far away from the results from intel benchmarks.

To this point I already activated Ultra Performance in Bios, got the advanced energy profiles back for windows (which was a real pain) and used throttlestop to improve powerlimits and heat control. So I think I maxed out my possibilities to this point.

Do you have options for me which I didnt see?

This should not be about being able to undervolt or something but why are there no Voltages listed in FIVR on Throttlestop? And why the heck is undervolting still locked for icelake and tigerlake? I thought the plundervolt exploit doesn't affect this generation anymore?

Stay healthy and positive everyone.

Probably need to wait for new version of ThrottleStop to add support for Intel 11th gen CPU, doesn't look like it's supported yet.

@Christian Reuter - The sad news is that for the 11th Gen U series, Intel has either blocked access to the FIVR controls or the FIVR that they have been using since the 4th Gen Haswell no longer exists in this design. Personally, I think Intel simply blocked access but I am always looking for a conspiracy to uncover.

This means that ThrottleStop can neither read or write any of the FIVR voltages like it used to do on previous generation Intel CPUs. That is why the voltage table in the ThrottleStop FIVR window is mostly blank.

It is possible that the 11th Gen H series will restore this feature or it might be reserved for the K series. Intel does not like to give anything away. Maybe you will need to hand over some extra money to get the voltage control feature enabled in their upcoming CPUs.

The 11th Gen U has great potential in theory but without voltage control, it is no better than Intel's previous CPUs. Thanks for confirming that.

Edit - Here is an example of why Intel likely decided to lock down their 11th Gen U series. The 10th Gen were beasts that could easily compete and beat their more expensive H series CPUs.

@unclewebb Thanks for this information. :rockout: Still sad to hear. I guess what intel might want to say is that we should just forget about it.

@INTEL NO! THESE ARE OUR SYSTEMS AND WE ALREADY PAID FOR THEM! :mad:

At the moment I really get in touch with this CPU but i'm still trying to understand it. The cinebench benchmarks aren't that big deal but I got the conclusion that I'm comparing not fair.

My i5 8350u is undervolted, I know the system very well and it's old so I would say i got the maximum out of this system.

On the other hand the i7 1165G7 is just released. So maybe there will be some updates or good guys who will find a way to give us back control over our own devices. I understand the idea behind taking the knife from the playing child and I also see that many persons would brick their devices but right now no one can get the knife which is plain stupid by intel. :banghead:

Especially when you see the scores of Apples M1 and actual Ryzen CPUs o_O

I'm using the Razer Core X with a Radeon Vega 56 as an external GPU and at the moment I don't get why I have so good scores with the 1165G7.
For example with 3D Mark Firestrike
i5 8350u 13052 Points
i7 1165G7 15100 Points.

This boost is huge and I also see this in ingame testing which I tried today. For example GTA Online, Shadow of the Tomb Raider or Kingdom Come Deliverance I have at least 10 FPS more.

At the moment i'm guessing either on the RAM. I have DDR4 3200 on the i5 and LPDDR4X 4256 on the i7 or on the Thunderbolt 4 Port, which has the same bandwith with 40Gb/s as the Thunderbolt 3 Port on the Elitebook but is now integrated on the chip so there could be a improvement in latency.

Right now I would say Thunderbolt 4 is the keymaker for this system for me. Still don't see any benefit in upgrading the GPU because only a few games are getting 99% GPU-Usage so the CPU and Thunderbolt remain the bottlenecks for gaming.
But hey... 15100 Points on Firestrike? Not bad for this setup.

@unclewebb is right about this... definitely not a conspiracy theory. Intel basically manufactures a bunch of chips, and the ones that come out the best have all their cores and features enabled and are sold as the higher end ones, while the worse binned ones that are not stable with everything enabled are sold as lower tier chips which. This basically means that even the U series chips have the same tech in them as the better stuff. Hence they don't want you milking a cheaper component. I can get in the 30-40W range depending on temperature and how warm the area around my charging port is (where the coil whine also comes from) on my i7-8565U based Dell laptop since I took the performance killing BIOS-updates as an excuse to play with ThrottleStop on a super expensive ($1500) laptop and I upgraded from the 432-point range to 750+ (100+ higher than out-of-the-box stock) on Cinebench R15. Now unless I'm pushing my machine hard and it throttles, I'm racing ahead (both idle and during use) at the maximum all-core turbo of 4090MHz and this thing feels snappier than brand new. I can only imagine when they find a way to prevent users from messing with the power limits, and in that case we are left at the mercy of the laptop manufacturers and will have to tolerate planned-obsolescence via BIOS updates. I literally caught Dell decreasing PL1 from 26W to 15W with updates! RED HANDED! They even messed up the fan algorithm, which I fixed by forcing the fans to max all the time so it can cool itself decently, but I can't get the fan speeds I had on stock settings before the bad updates... Sorry Dell, not only did you mess with the wrong geek who can fix your planned obsolescence but you also just lost a potential future customer.

Oh, and if my setup sounds like a heat problem, I did improve the cooling by putting furniture feet on the bottom of my laptop. Dell's genius engineers made this laptop in a way it suffocates itself on your desk.

@CompuNerd2K That sounds great. Which device do you have? The Elitebook x360 and the Inspiron 7306 are both ultra slim devices and both limited to thermal throttling. On my Elitebook there is a limit around 27W and the Inspiron is power limited around 18,5-20W, which I couldnt get over with throttlestop (could still try and mess around with bios or intel dynamic tuning but dont want to). Still the Inspiron already runs hotter with 20W (fan control is on maximum using hwinfo).

I'm sending the Inspiron back to Dell right now. Integrated Thunderbolt 4 is a big step for egpu usage but the cpu overall performance isn''t what I was hoping for. I guess I'll have to wait for Intel TigerLake H or Comet Lake S or maybe Ryzen with USB4/Thunderbolt 3 Support.

Don't get me wrong. I totaly get the physical limit with this thin devices so maybe I will look after a larger device in the future.

I picked up the envy x360 which runs great until it starts throttling which at point the fan starts screaming and i'm also having issues with Xe. I'm thinking about returning and getting something else.

I have an Inspiron 15 7590 2in1. Was annoyed that Dell messed up the performance on a freaking $1500 laptop. Had to get rid of the undervolting last we but it still performs quite decent. Thing got unstable as all hell with undervolting and I couldn't fix it. I'm still usually hitting 36W max in the best moments now which is still great, but I can sustain only a few hundred MHz less than undervolted. Sadly I might be looking at a hardware failure coming in the near future as I am experiencing once in a while some random hard crashes (screen blacks out, sound buzzes for a second and reboot, or freeze+buzzing) for no reason (I removed the undervolting, what more does this CPU or motherboard or whatever is messing with me want???) w/o BSOD. I'm still impressed I can get decent performance without undervolting as my first attempt at that worked way worse but maybe something else I played with in the mean time made it work better this time. O, and on a side note, the extreme CPU throttling down to 400-1500MHz in games can be easily fixed setting the GPU to run within Nvidia specs instead of Dell's attempted overclock that they pushed through an update (cursed EDP limits).

I picked up the envy x360 which runs great until it starts throttling which at point the fan starts screaming and i'm also having issues with Xe. I'm thinking about returning and getting something else.

Looks like cooling is insufficient and power limit tweaking won't help there. At least your fan algorithm is better than Dell's which doesn't kick the fan on until the CPU has been at 100C for an extended period of time and has already begun terribly throttling (nothing a little fan control software can't fix but still...)
