Jumping on the performance part, the Dell G15 has an all-new 12th Gen Intel® Core™ i5-12500H with 18 MB cache, 12 cores,16 threads and maximum clock speed up to 4.50 GHz Turbo. This intel processor sits above Intel® i5 11th gen and Ryzen 5 5625U. The biggest advantage of the newer processors is the performance. This laptop flies with medium to heavy tasks and Intel has done a commendable job at keeping the thermals in check. Heavier tasks do not take a toll on performance at all. That being said, the laptop runs cool and does not tend to heat up except while charging.
Gaming is an an area of focus on this laptop. The NVIDIA® GeForce RTX™ 3050, 4 GB GDDR6 Graphics is same as last year, but with newer processor it performs even better. Though better than previous generation, this laptop has come a long way. Triple A titles runs smooth in medium settings and if not pushed too hard churns out stable performance. If looking for heavy gaming, the variant with NVIDIA® GeForce RTX™ 3060 is recommended.
Overall, a very decent performing laptop and an easy recommendation for not very heavy gaming.
