Current processor is listed as retired! i5-2410M (in a Lenovo Thinkpad Edge E520)
Considering i5-8250U in an UltraNote Series 15.6 custom built by PC Specialist.
However comparing Performance specifications gives higher figures for some things on the old one than on the proposed new one. I'd like assurance that the i5-8250U will give me more speed and power before I invest in a new laptop.
Hope this makes sense to someone - as you can tell I know very little.
Here is a comparison of your old, and potentially new, processors:
You want assurance? Cannot do that as I have no idea of what you will install, its demands on the processor, memory, ssd, etc. Yes, make sure you have ssd, preferably nvme support.
PC Specialist UltraNote? Never heard of them. If I were purchasing a new laptop, I would want to make certain the support, including bios updates, would be there when needed. I would also be looking for a warranty of at least 3 years.
