As the sibling said those numbers are very configurable. e.g. around the x86 handhelds there are tinkerers running their U/P class chips at anywhere from 5W configured to 30+W configured (and with the appropriate cooling could totally

Actually Phoronix has power benchmarks for the ACPI power profiles[1]. Seems like a boost to ~28W or so with a long term average of 22-23W. (Note that this is SoC package power instead of the full laptop though, but that is pretty typical,

The problem with containers and graphics drivers is that those drivers have an userspace component. This depends on the hardware (e.g. AMD vs. Intel vs. NVidia all have different drivers of course) and in the case of NVidia this has to be e

A random attempt: Typically the application wants to draw stuff on the GPU. To do this it calls into the GPU driver, which builds a big memory buffer in some implementation-defined format that instructs the GPU what to do, and then the driv

I think the keyword might be an 8k executable, not 8k of code. If I compile the example with clang on my box (linux x86_64) I get a 17K executable, for which the .text section (containing pretty much the runnable code)is 0x291 (661) bytes w
