[Comparison] Intel Core i7-1255U vs Core i7-1165G7 – both chips look good
U-series CPUs have developed a lot over the years. What were previously chips that were only good for preserving battery life, nowadays, we see that these efficient CPUs also perform very well, giving smaller laptops some much-needed punch. Today we will see the improvement that a single generation can make, by comparing the Core i7-1255U against the Core i7-1165G7.

Conclusion
While there have been some definitive improvements, in terms of computational performance with the new Alder Lake CPU, the GPU performance is much better on the older 11th Gen CPU, both in synthetic benchmarks and in gaming tests. Of course, performance will vary from laptop to laptop, but the leads that the Iris Xe Graphics G7 in the Core i7-1165G7 was able to generate were massive. However, gaming performance is not what people are looking for from these CPUs, and we should expect other laptops with the same Core i7-1255U, which might offer different levels of power, thanks to better cooling, or general tweaks done to the chip itself.
