Gaming performance

Let's see how good Core i5-8305G and Core i7-8665U are for gaming compared with game system requirements. Remember that sometimes official requirements may reflect real performance inaccurately.

Advantages of Intel Core i5-8305G

5% faster in synthetic tests

Advantages of Intel Core i7-8665U

Much newer (16 April 2019 vs 1 February 2018)
Less power hungry (15 vs 65 watts)
HyperThreading (allows one physical CPU function as two logical ones. It increases performance, since while one logical CPU is waiting for data, the second may still do useful work)
