日本[Comparison] Intel Core i3-1215U vs Core i7-1165G7 – the Core i7 doesn’t care about your Hybrid architecture
With each new generation, Intel seems to further confuse their users, delivering more and more complex hardware that differs a lot. This started with Tiger Lake when Team Blue first released their U-series and H-series but then decided to split the latter into H35 and H45, which made no sense, as the H35 series was an underperforming mess, managing to get outclassed by much more efficient AMD chips.
Now, with Alder Lake, we have the U-series, P-series, and H-series, all three coming with different power limits. Today we have representatives from the two U-series, with the Core i3-1215U and the Core i7-1165G7, which have surprisingly close specs, especially for a Core i3 chip.
Today we are comparing the Intel Core i3-1215U against the Core i7-1165G7.

Conclusion
While the Core i3 does present a slight core count increase, the Core i7-1165G7 still brings enough raw performance from both its CPU and iGPU. And we’re glad it does since it would be a real embarrassment for a Core i7 CPU to lose to a Core i3. However, when choosing a laptop with each of these chips, do your research into how the device itself performs. As most manufacturers do it all a little differently when it comes to cooling, you can have the same CPU perform way differently.
