For example, does it support VT-d/VT-x? Well, in the command line, you can find out what processor it has and look it up on Intel's ark site.
For example, if you had an i7 3770k, you could go and get the full specs at by googling "ark 3770k" which gives you a link to the specs at : http://ark.intel.com/products/65523
In linux you can cat /proc/cpuinfo.
Well, I will show you the OSX equivalents. Instead of cpuinfo, we have sysctl To get the model name
in Linux In linux:
grep "model name" /proc/cpuinfo
In OSX, it is:
sysctl -n machdep.cpu.brand_string
To get full CPU info Linux:
cat /proc/cpuinfo
OSX:
sysctl -a | grep machdep.cpu
Want to know the core count and threads, you do another pipe grep. In OSX:
sysctl -a | grep machdep.cpu | grep core_count
sysctl -a | grep machdep.cpu | grep thread_count
Here is a full example:
