I need an i5 or i7 ,2.8 and above base frequency ,8th generation, good battery laptop . Graphic card is not my priority. i5 will suit my budget more. I am unable to find one with these specifications. Most laptops now have 1.6 GHz as basic frequency and turbo boost upto 3.4 or 3.9ghz but I will require a one with minimum 2.8ghz to run my simulation software. Can anyone suggest me a laptop with these specifications? If yes it will be of great help. Thanks ..
