That's a good chunk faster than this CPU despite it being 3 years older, alongside lower thermals due to the better heatsink design. The funny part? It cost me 1000$ vs the asking price of this laptop at 1270$. I also had a 20W limited preset- that still wiped the floor with the Snapdragon. 16000MC 1300SC.
😂😂😂😂
That's a lot of nonsense. First, the 12-core 7845HX has been introduced in 1/2023 while the first devices were available in March... so it's barely more than a year old rather than 3.
Second, you have no idea how TDP settings work. This is a Dragon Range desktop CPU in a notebook! You should measure the full system power drain from the socket like NBC does it to see what's really going on. Little hint: Under multi-core load like Cinebench this CPU easily sucks 200 Watts energy (no graphics, just CPU and system)!
Even my more modern 4nm 7840HS Phoenix with 8 cores having a TDP of 35W sucks up to 100W from the socket.
So until Zen 5 there is no competition in true mobile notebooks for X-Elite.
What sounds like a lot of nonsense is this defense- I don't know how TDP settings work? I hold the world record in 11800H performance in XTU.
I would post the link to it, but the site is refusing to allow me to post links.

I probably have one of the most intimate understandings of laptop power limits and undervoltage in the world.
As for your assertions of my understanding of TDP- I used a 90W power supply for the Dragon Range during the time i underclocked my computer- hence the underclock. My power brick for the laptop died and i was forced to use a severely underpowered laptop power supply. You know what's really funny is the assertion that the chip can pull more than 90W. Despite trying even shunt mods on the power input, it never pulled more than 90W, even with the core at full bore. The laptop required a charge to boot, but after it entered windows it was possible to use it without the battery dying/the power brick pulling more than rated caps.
If what you say is true about them pulling 200W, that would leave literally nothing for any of the other components on the board in a modern laptop. Still you have configurations with 230W power bricks and that's powering both a 4080 AND a 7845hx. Max TDP is 87W, even during multithreaded applications as evidenced by the multitude of reviews on the CPU.
200W from the wall is possible but the core itself is NOT hitting anything above 87W. Otherwise cooling it would be impossible in the majority of laptops.
Either you're being flagrantly misunderstanding for trolling effect, or you're simply just uneducated in the space. Whatever it is, doesn't matter, I still pity you.
