Check if you have 64bit by looking for "lm" in cpuinfo. lm stands for "long mem". This can also be used without being root.
Extracts the model name of the CPU and displays it on screen. Show Sample Output
There is no need for variables. I also added sleep to reduce cpu usage, however I didn't test it.
sort is way slow by default. This tells sort to use a buffer equal to half of the available free memory. It also will use multiple process for the sort equal to the number of cpus on your machine (if greater than 1). For me, it is magnitudes faster.
If you put this in your bash_profile or startup file, it will be set correctly when bash is started.
sort -S1 --parallel=2 <(echo) &>/dev/null && alias sortfast='sort -S$(($(sed '\''/MemF/!d;s/[^0-9]*//g'\'' /proc/meminfo)/2048)) $([ `nproc` -gt 1 ]&&echo -n --parallel=`nproc`)'
Alternative
echo|sort -S10M --parallel=2 &>/dev/null && alias sortfast="command sort -S$(($(sed '/MemT/!d;s/[^0-9]*//g' /proc/meminfo)/1024-200)) --parallel=$(($(command grep -c ^proc /proc/cpuinfo)*2))"

Check whether hyperthreading is enabled or not. a better solution as nproc should work on all OS with awk Show Sample Output
Information for only one core. Show Sample Output
No need for a colon, and one less semicolon too. Also untested.
This version is precise and requires one second to collect statistics. Check sample output for a more generic version and also a remote computer invocation variant. It doesn't work with the busybox version of the 'top' command but can be adjusted Show Sample Output
Alternative command to retrieve the CPU model name and strip off the "model name : " labels. Show Sample Output
