What intel integrated graphics works with photoshop 2020?

Hello, I am an inner city School and College teacher and am trying to support students working from home during covid lockdown . More than half of my students do not have a computer at home and I am trying to reccomend the cheapest laptops to them to run PS

.

I cannot for the life of me find a specific list of supported integrated graphics for photoshop 2020.
It seems that Adobe do not make older versions of photoshop available.

I have tried photoshop 2020 on a £80 intel i3 2nd gen laptop with 8GB RAM (HD 2000 graphics) and the whole interface lagged like crazy even after fiddling with graphics settings. Photopea worked perfectly fine on it even with complex PSD files and editing 4k images. An older cs6 version that I had hanging around also worked perfectly fine on it with the same complex files. 

Is there a comprehensive list of what integrated intel HD graphics will run PS2020? Can anyone confirm what the oldest (and therefore cheapest) i-series processor generation that can run photoshop?

I always reccomend the old dell desktops with gt710s /730s as they run photoshop fine for what we need and cost less than £150, screen included. The problem is that the parents say that they don't have desks or table space to set the PC's up  - students are studing sitting in their beds.

P.s, I am not looking for it to run well - I am just looking for it to be able to open and not have the crippling interface lag and screen tearing that is present on unsupported graphics. Students will be doing simple 1080p photomanipluations , photo retouching and pixel art - no 3d or 4k digital paintings!

Thank you in advance! You will be helping a lot of familes out here!
