Intel Alder Lake Core i7-1260P - The 12th Generation of Mobile CPUs in Review

[Redaktion]

After Intel already launched the H45 Alder Lake CPUs a couple of weeks ago, we now get the first laptops with the 28W P-series CPUs. We had the chance to test the new Core i7-1260P in Lenovo's Yoga 9i 14 and the performance is very good, but at the cost of the power consumption.

This was a missed opportunity. Again, why don't you perform power- or performance-normalized tests? You know that the relationships aren't linear. In your own selection, the 1260P has the best single-thread score in R23 - 22 % above 5900HS. That's quite a bit. And 20 % higher performance doesn't mean 20 % more power. It's not linear! And why is the 5800U missing? For example, look at the HP ProBook x360 435. Just 11 % lower multi-core score but at almost half the power. And contrast that with 5900HS. It even beats M1 but that's probably because it's R15 and not R23. But even in R23, it should be pretty close.

I don't know about other people, but I think that in ultrabooks, limiting boosting and power is a valid way of improving battery life and it also makes the machine quieter and cooler. Just because a manufacturer has decided to use a 64 W PL2 doesn't mean that I have to if it doesn't make sense to me. It's wasteful and inefficient. Acceptable in a workstation that never leaves an outlet for too long. But not in an ultrabook. I look at it in the positive way - I have options. It's certainly safer to reduce a limit than to push it. And that's another thing I miss - exploring these options, what does a BIOS offer.

You're forgetting the Tiger Lake G7 series CPUs that had 28W TDPs. So actually this is at least Intel's second attempt at a proper mid range series sitting between U and H.
