[chimerax-users] ChimeraX hardware recommendations

[Tom Goddard]

Hi Shawn,

  You are right that a MacBook with i5 CPU and 16 GB memory and Intel graphics will work fine for ChimeraX including making movies.  For large molecules, for example ribosome structures with several hundred thousands atoms, or large cryoEM maps, for example 512 x 512 x 512 and up you could benefit from faster AMD or Nvidia laptop graphics (MacBook Pro), and 32 GB of memory.  Another thing to consider is to keep data and ChimeraX on an SSD drive, not a spinning drive.  Today's SSD drives are 30 times faster reading data than spinning drives.  All Mac laptops only come with SSD drives I believe, but it is good to have enough SSD drive space that your data (like lots of cryoEM maps) does not have to reside on an external drive.  Usually 512 GB SSD will do, but again if you work with lots of large data 1 TB SSD could be helpful.

  Sorry our ChimeraX web site is unexpectedly down this morning due to some server upgrade issue.  Should be back online later today.

	Tom
