Here are (probably all) the latest Inel i5 and i7 (only 7th and 8th generation) processors that are used in laptops today. The Passmark values are benchmarks from Passmark. As we should all know by now you should not judge a book by its cover and so you should not judge an Inel processor by its brand name. The results show that i5 processors can perform better than i7 in some cases.
To me it seems Intel processors are becoming more and more similar in performance. As The Verge wrote last month :
In the past, Intel could rely on microarchitecture changes one year and production process shrinkage another year to maintain its momentum of improvement. But the infamous Moore’s Law sputtered to an end back in 2015.
This is also reflected in the latest flag ship products from all vendors. Apple has the Macbook Pro, Lenovo has the new Yoga and Microsoft has the Surface Book 2. All of these are very similar in performance, that is if you are looking at average user demands.
Because of this, if you want a laptop with a high end CPU it is a mess to differentiate the latest i5 and i7 processors. They are all quite good. Hence why I made this chart based on pretty much all high end laptops available on the market today. Personally I would say that anything above 8000 points in Passmark benchmarks is a good long term investment if you are looking for a work PC for IT employees. For simpler usage I would go for 700 points and up.
