Intel Core i7-8565U vs Intel Core i7-8750H – efficiency vs power


The everlasting question in the laptop world – are the ULV processor sufficient enough to replace the higher powered – H-series or they are still lacking behind. Theoretically, a 45W CPU should offer a lot more than a 15W one. However, in practice, the difference is not even nearly that big that it should.

Specs overview

Let’s start with the obvious – Core i7-8565U has a TDP of 15W, while the Core i7-8750H – 45W. Next, the ULV processor utilizes four-core/eight-thread configuration, while the more powerful CPU has six cores and twelve threads. They work at 1.80-4.60 GHz and 2.20-4.10 GHz (Base-Turbo), respectively. Cache-wise they are very close with the Core i7-8565U having 8MB and the Core i7-8750H being equipped with 9MB.

Another great difference between the two is in the memory support – ULV CPUs are limited to 32GB, while the Core i7-8750H can go up to 64GB and 2667 MHz of DDR4. Additionally, the maximum memory bandwidth that can be reached by the Core i7-8565U is 37.5 GB/s, whereas the Core i7-8750H is able to go up to 41.8 GB/s.

Benchmarks

Since we’re talking about laptop CPUs, cooling capacity and power delivery play a huge role in a certain processor’s performance. This is very well seen in the case of Core i7-8565U, where we saw the ZenBook 15 UX533 to completely destroy its competition with the same processor. However, when we put it side by side to one of the best Core i7-8750H performers – the Lenovo Legion Y740, we see a clear victor of this race.


Conclusion

Certainly, the Core i7-8565U was no match for the bigger and more powerful Core i7-8750H. However, if we adjust the scores to a single core, the difference basically vanishes. With that said will hardly experience any difference between the two, especially in day to day tasks. However, if you are more into gaming or, per se – video editing, the choice is obvious – go for Core i7-8750H.
