starts with Ryzen 9 79xx, dunno why you'd think that's mid range (unlike the other mobile 7000 names that are indeed just a scam to sell zen2 to ordinary people who don't follow amd's presentations ).

kinda scummy to mix in older ryzens into 7000 series, but that's typical.
Yeah I didn't watch amd presentation either so I thought 7945HX mean midrange and high end is like 7995HX or something LOL
Can you TOUCH a dragon would also be a nice catch phrase...
''The GPU under stress will reach 80 Degrees C. Both values are to be considered quite moderate. ''AMD Ryzen 9 7945HX (Dragon Range) processor review - Generic Thermals (guru3d.com)
80 degree component on a good looking laptop ? Yes, touching it would be interesting.
And pardon me for my reading skills, but I read it costs 3.4K United States Dollars and theres no word ''aluminium'' in the Review.
So its a Plastic Enclosure for 3400$, running at 50degrees all around with 80 degree component.
I tested stock 12900k 4800mhz xmp vs 12900k stock with 7000mhz tuned memory last year.
Got 35% higher min fps in Battlefield.
Running 8533mhz with 13900k now.
That's an expected result, since you're feeding a much faster CPU that is working harder due to what I assume is a faster GPU.
Faster RAM only makes your PC less slow. There is a point of diminishing returns, and when it comes to mobile CPUs, to @TLD LARS point, halving the latency isn't going to have as significant of a benefit when you're bottlenecked by lower clock speeds that only further drop from thermal throttling.
I feel there is absolutely room to have faster mobile RAM (especially for the price point of this laptop) and it would make a noteworthy difference (especially those using the iGPU) but for those with dGPUs, it's not that important.
I see people here are not very familiar with gaming laptops' temps. Generally the CPU can push to low 90s while gaming/running heavy tasks, and as long as it's not throttling that's temp is... fine. Good laptops with beefy cooling system (or the average one but with tweaks - like better thermal paste, undervolting,etc.) can lower that to low 80s or high 70s, sometimes even lower if you're willing to push the fan to max (trust me, not worth at all). GPU in general will stay around 60s-70s degree, but for the big boys that can maintain 165+ W, it can push into 80s territory (Tj max for the mobile Nvidia GPU is 86 I believe).
From desktop users' point of view, those are very high numbers, but it's perfectly fine in long term. I personally never had any dead mobile CPU/GPU before, despite only using laptops for last 7 years and play games at least 2-3 hours everyday.

That's true, I have 15in Acer Triton with 45W 10875H + 90W 2070S, to keep normal fan noise I had to reduce CPU TDP to 40W and GPU to 80W (already repasted with thermalright TFX)
I gave the laptop to my nephew, hopefully he can use it for a long time, probably gonna need repasting after some time.
I don't understand how is this 55W CPU? Or even 75W?
From AMD:
AMD Configurable TDP (cTDP): 55-75Whttps://www.amd.com/en/products/apu/amd-ryzen-9-7945hx
From Asus:
Ryzen 9 7945HX: 55W in 'Turbo' mode; 65W in 'Manual' mode
RTX 4090M: 175W
!!On HWINFO screenshot it shows 103W Maximum Power for CPU Package!!! (core + soc)
AMD's TDP has nothing to do with actual power consumption because there is no power in their formuila.
As far as HWinfo goes, it can only show data derived from sensor and because reporting is spot on, HWInfo devs made power reporting deviation (probably done for very limited amount of boards). I assume HH on the other hand is using actual tool to measure it.
I guess Zen4 is kind of dissapointment as a whole anyway. Too bad AMD has to copy intel and nvidia in everything... I would not be surprised if CPU losses less then 10% at actual 65-75W...

Except that's not true.
I take it you are referring to that famous AMD's TDP definition in terms of cooling required to dissipate heat. And even more famous saying: TDP ā POWER
This is a misconception owed both to criminally low level of public understanding what power and heat mean and to AMD's marketing Robert Hallock (the other famous example of him sowing confusion is from early FreeSync days supposedly needing vsync=on)
I'll quote gamernexus:
A watt is a watt. Wikipedia says a watt is āa derived unit of 1 joule per second, and is used to quantify the rate of energy transfer.ā In a Reddit post, AMDās Robert Hallock says āTDP is about thermal watts, not electrical watts. These are not the same.ā
In a literal sense, thatās not true: āthermalā and āelectricalā watts are the same unit, in the sense that a cup of flour is the same as a cup of water or a pound of feathers is the same as a pound of bricks. Moreover, the rate that a chip draws energy (as electricity) and releases energy (as heat) should be the same over a sufficient amount of time, since no physical āworkā is being done." There is no translation about any axis and no emission in any other form, such as light, and so heat out will be nearly perfectly 1:1 with power in.
What that means is: AMD might be talking about "thermal" watts - notice quotation marks - they are needed because there is no such thing as thermal watts. This should be your 1st hint there is something wrong with your definition: If in any technical discussion, you are compelled to use quotation marks to indicate that a term should not be taken literally, you need to come up with a better term. Technical discussion is not a Shakespeare's poem - everything SHOULD be taken literally.
Hallock might be talking about "thermal" watts - but they are just watts. No different than "electrical" watts.
But if you follow Hallock's mental picture of "electrical" watts being converted to "thermal" watts - such picture will work only if you remember that ALL electrical watts end up as thermal watts because:
They can't be created out of nothing or destroyed
CPU is simply a 100% efficient heater - electrically and thermally no different than any coil heater or a wire
And since total energy is conserved, so are the watts - "thermal" or "electrical"
TLDR;
If your CPU is using 100 watts during a prolonged amount of time, and you want it work properly, then you can't have the heat building up - therefore you need a cooling system able to dissipate 100 watts of heat .

(85W for AVERAGE, but who cares about average power which includes time spent out of maximum MT load)
Guru3D Laptop power measurements:
!! Idle: 33W, Single Thread 61W, Multithread!!: 161W !!
Yeah I get that it blinks and whatnot, but there is 130W of difference between Idle and Multithreaded.
Display ON in idle?
If it is then these 130W of difference likely comes from 90W Cpu Core + 10W CPU graphics + 30W blink-blink-brigther-display-disk-misc
Which is in line with Hwinfo showing 88W max for CPU core.
When looking at AMD CPU TDP think of it as guidance on how powerful the cooler should be at minimum.
For Intel CPU check the Intel Ark for Maximum Turbo Power as minimum. The advertised TDP ( Processor Base Power on Ark site ) may not even be enough to run nonturbo speeds for some workloads. Advertised TDP should be ignored in my opinion.
