My basic Lenova ThinkPad E14 Gen 2 has an Intel Core-i3 CPU (product number

Oct. 9, 2022, 3 a.m.

My basic Lenova ThinkPad E14 Gen 2 has an Intel Core-i3 CPU (product number 20TACTO1WW) and is used mainly for CAD purposes. Unfortunately, I didn't get the E14 option to have an Nvidia GeForce MX450 2GB GDDR5, as I thought the discrete Intel graphics would be adequate. Recently, I have started having problems where image manipulation, graphics and design AI (Artificial Intelligence, Like Stability-Diffusion and X-Plane), wont work because I do not have NVidia. Can I upgrade my E14 Thinkpad laptop with the Nvidia GeForce MX450 2GB GDDR5 (or better) myself? If so, can anyone let me know how to do it and what hardware to get or direct me somewhere with this information?

You need to replace the entire motherboard

Thanks . I was hoping that I could upgrade the Core-i3 CPU with a higher spec one that includes discrete Nvidia graphics instead of the Intel architecture or replacing a graphics chip on the motherboard. Is there an expansion slot on my board that will take an Nvidia card? It would be less hassle and more economic to simply buy another laptop than changing the motherboard.

I would look into replacing the laptop then

Another option is a thunderbolt GPU but that isn't so portable

Thank you for all your excellent suggestions . I am leaning towards your eGPU solution & upgrading my CPU to Core-i7 or i9, if possible.

CPU is not upgradable either

That sucks. Whatever happened to modular systems that made computing so versatile?

Intel hasn't realeased a socket mobile CPU since 4th gen

Try to find one configured like you want and then sell yours to offset the costs. The video is not upgradable without replacing the motherboard with one that has the GPU already.

Thank you has suggested a Thunderbolt eGPU connected with Nvidia.

I wonder if you'd be better off with something like a W520 with the built in Nvidia Quadro 2000M graphics. These are not as sought after as some models, have Core-i7 processors, and make a great workstation. Also is one of the last models to have classic Thinkpad features.

that Quadro is glacially slow compared to the IGPU of Ice Lake

I was basing it on my experience with a GeForce MX450 in a laptop I had some time back.

You are both very up-to-date and knowledgeable
