Both battery life and multicore performance are important. The thing is tho, on x86 side the battery life improvements are so incremental relative to gen-on-gen price increases that it makes it almost not worth it anymore. On the other side, zen 5 had severe latency issues. I know these were fixed on desktop but have they been for mobile strix too? Even if they are now, still doesn't change the fact that there's terrible pricing for them and availability is not great either.
Don't know why people are getting so defensive on the side the choose to die on a hill for. Everything sucks anyway. I would say, go Apple instead but even with them only light to medium load battery life is solid. As soon as you look at heavy load, it's 1-2 hours runtime at most.
Looking forward to Oryon v2 and nvidias AI PC's. Hopefully, they can make some significant improvements in these areas. We will see.
