[chimera-dev] Hardware Requirements

[Greg Couch]

Hi John,

What hardware ChimeraX needs depends entirely on the data you want to 
look at and how you want to visualize it.  For example, if you want to 
use a VR helmet, you'll need a PC with high end graphics hardware.  But 
if you're looking at normal proteins, then almost any recent computer 
will do.  For your specific questions, ChimeraX's speed is usually 
dominated by the single core CPU performance (including the speed of 
main memory) and the speed of the storage.  The exceptions are VR, where 
high end GPUs are needed for speed, large models, where more GPU memory  
and speed are needed, and high resolution displays which need more GPU 
memory.   For main memory, 8-64 GB, and for disk memory, reserve 1GB for 
ChimeraX.

tl;dr -- buy a gaming computer.

     HTH,

     Greg
