Battery life is based on playing a 720p video file so most of the expended power will be in the video decoder and screen not the actual CPU. It's also dependent on the battery size in the laptop being tested so pretty much impossible to compare on any like for like basis.

Yep, also putting all of the laptops at "50%" brightness isnt an equal comparison. One panel's 50% might be the same brightness as another's 100%.

Where is the video decoder unit located though?

[cogman10]

CPU to be sure. However, low power video decoders are really nothing new for Intel or AMD.

Also, the codec being decoded matters a lot. H.264 is trivial to decode at this point while something like AV1 will require a bit more power to decode.

[ac29]

Video decode is part of the GPU, not CPU. They are on the same tile in Lunar Lake though.

[VincentEvans]

Spot on. Why not use any more or less standard cpu benchmark? The publication is either being strangely incompetent at this, or deliberately misleading.

Success despite incompetence isn't that strange.
