#minimum assured power on high end laptop cpus

Earlier today, someone was trying to convince me, and about five other people with “desktop replacement” Intel laptop CPUs (275HX, 13700H, etc.), that our chips are basically too weak to run games. (HELLDIVERS 2, DayZ, more, dispite having far lower minimum requirements.)

His claim is that once PL1 Tau expires and the CPU stops its boost phase, it supposedly drops down to the minimum assured power, in my case with the 275HX, that’s just 45 W. I’m stumped, because:

  1. 45 W is basically idle wattage, that’s nothing for a CPU.
  2. If this is true, what’s the point of PL1 (long-term power limit) existing at all? It makes zero sense.

And in my specific case, it’s even stranger because on the Legion 7i Pro Gen 10, PL1 is configurable through the LegionSpace app, and it’s the same situation (They also have configurable power settings or presets) for everyone else he’s telling this to.

those chips are absolutely perfect for gaming

reef isle
#

which is what i said.. minimum assured is to do with

plucky hazel
#

they idle way lower than 45w

reef isle
#

oem and manufacturing

reef isle
#

which is far too low for smooth gameplay on those chips

plucky hazel
#

i got a 8750h that has a tdp of 45w but draws 90w

#

so

reef isle
#

fair enough but

#

he’s suggesting it drops down from 205 watts to 45.

plucky hazel
reef isle
#

it is

plucky hazel
reef isle
#

yea

#

205 boost

plucky hazel
#

insanity

reef isle
#

strong cpu!

plucky hazel
#

strong heatsink

reef isle
#

yes!

#

anyway

#

but beside my point

#

he’s trying to say it defaults to the minimum assured power of the cpu

#

which is what intel assures is the minimum wattage that cpu will be functional at

#

any less is crash territory

#

instead of PL1

plucky hazel
#

you can just kinda like

#

adjust it

#

through throttlestop

#

or smth

#

so it boosts forever

reef isle
#

i don’t think that’s that though

#

there’s base power and minimum assured

#

base power you can change

#

which is like pl1

#

in my settings

#

long term power limit

#

of 160watts

#

and pl2 is set to a boost of 205watt

#

pl1 tau 56sec

#

he suggests after it boosts to 205 watts

#

instead of dropping to 160 after 56sec

#

it goes to 45

plucky hazel
#

i like to crank everything up

?

plucky hazel
reef isle
#

exactly..

plucky hazel
#

yeah

#

alr it makes more sense now

reef isle
#

would that not cause severe stuttering and maybe even crashes with such a huge performance drop lol

plucky hazel
#

maybe worse performance

#

but new chips op

reef isle
#

the issue reported is low fps in helldivers, down from a consistent 120-140 to 45 fps. but still even then,

#

you wouldn’t get 45 fps at 45 watts on those chips

plucky hazel
reef isle
#

i did figure out it’s just a game bug

#

and hwinfo never shows signs of dropping to 45 watts for no reason..

#

but this guys still confident all high end intel laptop cpus are garbage

#

and it stumped me

plucky hazel
#

permanant boost is perfect

reef isle
#

i prob could

#

not a consistent 205 watts boost

#

probably 190 tops

#

i have a external laptop cooler and everything shits pretty chilly
