It is a better single core, slightly worse multicore for almost half the power consumption. What's even the point of the HS version? Combine the 30W U version with a 100W 4060/4070 and you have a gloriously efficient and cool laptop.

You don't need a dedicated GPU when you get a Ryzen 7840 – that's the entire concept. If you opt for a GPU that exhausts your battery life, you might as well go with Intel.

Polo, I have a 7940HS laptop, I used to have an i7-12700h, and both have dedicated GPUs yet my current laptop with the 7940hs gets at least 2-3x the battery life. My Intel laptop had a 140w 3070ti and my AMD laptop has a 140w 4070. The difference in battery life is very very very apparent and I have very little loss of performance when unplugged.

Polo, Intel has finally caught up with AMD in terms of integrated graphics through their "Ultra" lineup.
