Hi
@Stelios,
Looking for a 14" laptop may be a challenge with a good GPU with TDP (Thermal Design Power); higher is better with good cooling naturally. Specially for V-ray application (Rendering). You can have a look at this
link and get an idea of the performance for the GPU you'll need.
SketchUp, I know it uses a
single core speed rather than multicore. Whereas AutoCAD may be more flexible with operating with multicore.
As for Photoshop, it would comfortably work by choosing the laptop for above uses. Just remember to have a good amount of RAM (more the better, for larger projects).
I think you can start by looking at Asus ROG series; Zephyrus. They have 14" models 2022. and older. I am not sure about their latest models yet. Effectively, you are looking for 'gaming' laptop. As it gives you the best price per dollar/GBP/Drachmas/Euros/etc.
Thing to note, nvidia RTX cards are what you're looking for. Stay away from AMD GPUs. As they are not officially supported/optimised by most 3D design software.
If you do find a laptop, please do inform me. As I too am looking for a small form factor laptop for similar uses. That isn't the cost of ten thousand gyro pittas, and the blood of hundred Trojans.
Regards,
