Dell Pro 14 Premium perfectly exemplifies one of the major benefits of Intel Lunar Lake

The Dell Pro 14 Premium with Lunar Lake is now shipping to replace the outgoing Latitude 14 7440/9440 series. We've talked much about how Lunar Lake prioritizes power efficiency more so than on previous generations and the new Dell Pro 14 Premium is a great example of the new Intel CPU at work.

Our graphs below compare the CPU and GPU performance differences between the Dell Pro 14 Premium and Latitude 9440 2-in-1 as well as their power consumption levels under high loads. Most notably, the newer Dell model can offer over 2x the graphics performance over its predecessor while consuming almost 35 percent less power in the process for one of the biggest gen-to-gen performance-per-watt gains we've seen from the chipmaker.

The CPU gains between the two models are comparatively smaller, but they are noteworthy nonetheless. The difference is great enough that the Dell Pro 14 Premium can outlast the Latitude 9440 2-in-1 in our battery life test by significant margins even though the latter comes with a lower resolution IPS panel and the same 60 Wh battery capacity. Similar benefits are reflected throughout most of our tests involving Lunar Lake laptops from other manufacturers and their respective previous generation counterparts.
