[QE-users] Required configuration of desktop computer for DFT calculations

[Souvik Biswas]

Thank you so much for your reply, sir. I was trying to buy my own system so
that I can work anywhere, can you please suggest me that ryzen 7 2700x or
3700x will be a good processor for DFT calculations? And will i have any
edge over intel i7 9700k? Thanks in advance. It will be great for me if you
suggest some benchmarks.

Sincerely,
Savy
