Lenovo Yoga Book 9 13IMU9 2-in-1 dual screen review: Core Ultra 7 155U and Arc 4 are a mixed bag

[Redaktion]

The dual-screen Yoga Book 9i is back this year with new Meteor Lake-U CPUs and integrated Arc graphics. The differences and performance advantages between the 2023 and 2024 models, however, aren't what we were expecting.

This multimeter thing is already getting weird...

Please include a test report on HDCP compliance for the laptop display. It turns out that Lenovo Yoga Book 9i and Yoga 9i OLED screens are NOT HDCP compliant, as reported in the Intel Graphics Command Centre. This stops 4k HDR streaming, eg Netflix. I'm reporting this as I own this laptop, the latest Meteor Lake version.

I don't think I'll be missing out much from last year's model. That is still a capable laptop to own.

One of the more interesting things here is the gaming results compared to the HP Spectre x360, because it has the same PL1 (24W), but with an Arc-8-graphics.

So we can see the performance difference at the same wattage from Arc-4-graphics to Arc-8-graphics is around 35% (average). So 100% more graphics cores means 35% more performance. Not worlds apart I would say.

That becomes even more interesting when you consider that desktop Arrow Lake will also get the Arc-4-graphics solution. I still wonder if the performance difference would be the same on higher wattages (e.g. 65W desktop power level).
