interesting to see that the i7-1370P model had the same battery life as the Ryzen 7 7840U - I would have expected a larger delta

That's kind of strange too, the notebookcheck article shows the Ryzen version having a much larger runtime in their benchmark compared to the i7-1370P version.

Search for "Battery life", you'll see WIFI runtime at 726 vs 527 (I assume minutes) for Ryzen vs Intel respectively.

I'm waiting in line for my GPD Win Max 2 w/7840 to turn up, to replace my long-in-tooth T480s...

Ah, it was already mentioned in the previous thread too, that Ars review team had the ports configured incorrectly which resulted in higher power draw.

The alleged proof that they configured the ports wrong is a picture from their Intel framework review. "We're using the same pictures as a previous review because it's the exact same laptop." You can see the same picture here: https://arstechnica.com/gadgets/2023/05/review-framework-lap...

The Ars review also even mentions this problem: "Framework also says the rear ports enter a "high-power mode" when USB-A modules are connected to them, which can reduce battery life."

Either way, glad we have a new product we can blame the user for holding wrong.

The notebook check power figures make no sense when you consider that their measured runtime was longer than what would be possible if the laptop was at idle the whole time. Their average idle power draw was at 6.5 watts, the battery is 65wh and the overall runtime is... 700+ minutes? What am I missing ?

Even if we assume that the test was completely at idle, Intel seems to draw less power than AMD when idling so I'm still puzzled by the run times.

Now that Intel's on the chiplet train too I think we're going to see a significant reduction of AMD's lead there.

IME Intel is a bit better at the whole power optimization thing when their chip designs aren't gobbling watts to boost performance.

Chiplets are actually bad for energy efficiency.

Exactly that's why AMDs Laptop chips are monolithic and not chiclet.

Also note that the AMD part isn't a chiplet part.

That is quite deliberate.
