i5-1235u has better single core performance so better gmaing performance?

Nowadays, pretty much stable power availability is almost everywhere. Be it by car, train, home, office, etc. So, there is no need to think about battery life all the time unless you don't want to sit in a place and work.

Doing research for 2in1 laptops... power is everything (almost) on these things. The performance lost on the 1235U is well worth the power savings AND the price sizeable price difference. The reality is that most things a 2in1 is used for will be GPU based anyway. If you're only going to do CPU-intensive things and don't care so much about battery life, and the price isn't so important go with the i7 1260P anyway.

No point in buying i5 1235U over 1240P unless there's a big price difference!

I like battery life, so I'll take the 1235U at only 15W over a 28W 1240P any day of the week. A U-series processor-based laptop is going to have a much longer-lasting battery than one with a P series (assuming comparable battery size & weight specs). Meanwhile, the 1235U is pretty much as powerful a CPU as the 1220P, which is one step down from the 1240P. IRL, you won't notice the difference between any of these processors unless you do CPU-intensive tasks all the time, in which case none of these processors is a good choice and you should be looking much higher up the CPU line.

powerSavvy, I agree with you... But if there is not much price difference then I would rather go with the P series.. thanks.

So I am choosing a 1240P processor based on all factors. I think that was the best in both.
