The battery life is quite horrendous. Bizarre not to offer usb c charging
Just web browsing lasted 85 minutes
The same model with an i9 13950hx and 4090 did 260 minutes.

For all things AMD; come talk about Ryzen, Radeon, Threadripper, EPYC, rumors, reviews, news and more.

The culprit is the 7945hx, due to it being chiplet, the iodie is basically a separate processor that can't be turned off.
USB-C probably can't provide the necessary wattage.
As for the battery life, I have no idea. I have a Lenovo Legion all-AMD and it's been quite good. The successor to mine apparently can last up to 9 hours for non-gaming workloads. It sounds to me like Dell messed something up here in a big way.
USB-C can deliver up to 240w… that should be enough to power any laptop.
Eh its the CPU. It's well known by now the 7945HX is a desktop class chip. It doesn't have any mobile specific optimizations.
Am quite confident something like 7940HS combined with the same 7900M will have much better battery life.
Other RDNA3 based laptops that has 7040HS class CPU paired with them have class leading battery life.
Other rdna3 laptops top out at the small monolithic navi 33 die though.
M3 Max should rip that.
no?
because it's a physics problem. how do you have the same power level as a desktop while only having a fraction of cooling capacity?
tldr; you don't. one or the other, son.
not to mention how are they implementing this? dell is fucking incompetent. the dGPU (any) is going to be inefficient as fuck and this is a laptop..so is there an iGPU for use on battery or are we good with 1hr runtimes?
i have a 3080 in a laptop and it sounds like a jet engine when it needs to
