And here is another proof of everything that I wrote about above ...

Quote from: Dorby on May 18, 2022, 17:03:02I don't understand these baffling choices Acer, Asus, and Lenovo are making this year by using 45-120 Watt H-series chips (i9-12900H, i7-12800H, and i7-12650H) inside Ultrabooks without any dGPU.

Because they are cheaper than U/P series. And the H series has a larger cache and otherwise connects to discrete cards on the link always x16, unlike x4-x8 on the QPI bus for U / P series. Plus there are more pci-e links.

The U/P series always has a built-in TB4.0 (2x2) controller, the H series does not have it, an external one is needed. And if you do not want to make a laptop with TB4 ports, you can save on the price of the H series by lowering its TDP below the norm according to Intel specifications. What do they do in practice? And they don't care that this series is less optimized for long battery life - most consumers use laptops from a wall outlet more than 90% of the time. They don't care about autonomy. Yes, and many do not care about TB4 ports, which means that they can save an extra $30-40 of cost relative to U / P series.

PWM is some nasty tech.

Asus in its OLED series (in some, you need to study the issue carefully for each series) now uses dc dimming and supposedly they stop flickering at low frequencies with such a scheme. But the price for this drop in native contrast is 50-100 times immediately, color reproduction and real color depth (dynamic range) are worse. But just about the fact that the contrast drops from 1000000:1 (100000:1 minimum) to 6000:1-15000:1, Asus marketers are of course silent, assuring customers that there are still the same 1000000:1 (or "infinite" contrast) .

Well, the resource of such panels in Asus laptops is declared at about 7000-8000 hours, instead of at least 15000 hours for modern IPS.

At the same time, Asus imposes a special screensaver that wildly annoys users. If it turns out to be turned off, then the resource before burnout drops further, even more.

When running design software, does the Core i7-12650H have sufficient power?

You are too modest. With earlier Intel CPUs, ca. 16h battery life was possible even for 15W TDP chips. But indeed, the question remains why manufacturers do not offer these in many models. Wrong design priorities most of the time.

I don't understand these baffling choices Acer, Asus, and Lenovo are making this year by using 45-120 Watt H-series chips (i9-12900H, i7-12800H, and i7-12650H) inside Ultrabooks without any dGPU.

Why not go with something efficient like i5-1230U (9 Watt) and pair it up with big battery + 2K OLED display?

I'd like to see some real 10 hour "work-day" battery life on a laptop that isn't a Apple MacBook Air. That means 10 hours on Notebookcheck's "WiFi Websurfing max. Brightness" battery test.

No amd option?
