Can laptop on battery run games with dedicated gpu at full clock?

[crystal6tak]

I'm having an argument with a friend. However the question I'm asking is if a laptop is running on battery (so it's not plugged in) can the person force the dedicated gpu to run on it's full clock for gaming. My friend says it's impossible due to the battery not able to provide the constant power source needed. So can it? For some extra information we're arguing about gaming laptops at the $1300 range.

 

Backstory:

My friend and I am arguing on portable PC gaming solutions on the go like on buses and mrt. He's siding with Razer edge pro with the gamepad controller and I'm siding with a gaming laptop in a backpack with nvidia shield. So far his whole argument is that my solution can't beat his in terms of performance as a $1300 gaming laptop on battery can't beat the razer edge in terms of performance. The razer edge pro + gamepad is $1600 and the nvidia shield is $300 which is why I arrived at the $1300 gaming laptop.

of course it can

[crystal6tak]

of course it can

that's what I told him...but apparently to him without an actual proof he doesn't believe it O_o. Do you have a link to someone using a gaming laptop on battery running gpu at full clock though? I'm trying to find one but no luck.

[ShadyHost]

not for very long, but yes. 

 

The notebook itself only knows that it is getting power, and it doesn't really take into account where the power is coming from or how long it will last.

pretty sure 99% of every laptop in the world car run at full  using the battery

your friend is misinformed

you can also serach the watt outputt on the battery and the powerconsumption on full load and see if the output is higher than the power consumption, also you can just run benchmarkss en check it yourself xD

Of course it can. It just means the battery would die pretty quickly.

 

On a side note though, on my laptop, I've noticed it performs slightly slower when it's not plugged in. Then again, it is a 4 year old Toshiba, that cost $800 when new.

Mine can do it with a Intel i7 and 3GB 445M, but the battery life shrinks to 30mins though.

[legopc]

yes you can

Mine with an I5, 6GB ram and 640M Le runs about 1-1.5 hours on battery while gaming. (that said it is an ultra book)

My laptop can run at full load on battery power easily. I wondered about this myself and ran a few tests. Both results, on and off battery power, were within margin of error.

At most you just put it on performance mode lol it won't last long on just batter though

[diiPex]

Most laptops by default throttle down the gpu clock when unplugged, but this can be easily changed in the power settings.

I have an alienware m11x and I can play on it for 2 hours on battery.  I wouldn't count it as a power house, but place stuff fairly well.  But yeah if it slows down just switch it into performance mode and it should work the same 

[NinjaStyle013]

If a car isn't getting gas pumped into does it to slower?

No. Tell your friend he's wrong then beat him with a water cooling hose.

[Lord_Karango17]

Normally yes, because the power brick and the battery usually output the same wattage, thus allowing users to remove the battery while pluged in an still use the device normally.

but if you do anything crazy like overclocking/overvolting the components like ive done then other components will effectively be under clocked as the battery/ power brick only supply enough watts for the stock config...

[Electronics Wizardy]

yes you can but it you mac have to change it in the settings
