Are you sure that is supposed to be the same result?

Example:

dle3ams@3120-2914:~> grep -i ^processor /proc/cpuinfo  | wc -l
2
dle3ams@3120-2914:~> ls /sys/devices/system/cpu/cpu* | wc -l
24

Dare to tell me where I got my other 22 CPUs from ? :)

At best you'd probably want something like:
  ls -d /sys/devices/system/cpu/cpu[0-9]* | wc -l
if you really want to use sysfs in this way.
