[Comparison] Intel Core i3-1215U vs Core i3-1115G4 – healthy increases in every metric

Finally, we have our hands on the Alder Lake U-series, which is supposed to bring even better efficiency to the table, extending laptop battery life to new heights for Intel. The Core i3-1215U that we have here should be a leader when it comes to that, but as of now, we have been left kinda disappointed.

At least there should be a good increase in performance, right? This is what we’re here to find out, as we compare the i3-1215U against the Core i3-1115G4, which doesn’t bring the new flashy efficiency cores, but can clock decently higher, which might matter a lot more.

Conclusion

The Core i3-1215U brings overall increases to both CPU and GPU performance (including gaming). Battery life is increased as well, however not at a level that is still enough to challenge Ryzen CPUs and their levels of efficiency. Still, for daily driver devices that won’t do more than browse the web, check emails, and consume media, we see the Core i3 as a fantastic offering, as long as pricing is adequate.
