I have a Dell Latitude 5590 with an intel core i5 8250U CPU. Running Adobe Premiere Pro on this laptop is pretty slow and I'm looking into speeding up my laptop with adding RAM or swapping CPU. I have two questions with that:
1. Can you even remove the CPU from my laptop or is it soldered in place?
2. If so, would any of the other i5 8th gen processors like the i5 8400B work as a substitute?
That cpu is soldered (BGA-1356), not all are, depends on the laptop.
At 3.4GHz, it shouldn't be slow at all, but running at max turbo will also be dumping 25w instead of the standard 15w, or low speed 10w. So if looking for speed, make sure the boost is on, set power plan for max etc and TDP-up.
Yes, 16Gb of ram will help. As would more than a 256Gb ssd which is probably approaching full or close.
