You can toggle 'single CPU' mode inside top by hitting the 1 key. From man top:

       Summary-Area-defaults

          l - Load Avg/Uptime  On  (thus program name)

          t - Task/Cpu states  On  (1+1 lines, see `1')

          m - Mem/Swap usage   On  (2 lines worth)

          1 - Single Cpu       Off (thus multiple cpus)

For example, with single CPU 'on' (the default, apparently):

top - 22:42:17 up 1 day,  1:11,  1 user,  load average: 0.04, 0.05, 0.20

Tasks: 225 total,   1 running, 224 sleeping,   0 stopped,   0 zombie

%Cpu(s):  0.8 us,  0.7 sy,  0.0 ni, 98.3 id,  0.2 wa,  0.0 hi,  0.0 si,  0.0 st

KiB Mem :  3936368 total,   293968 free,  2812496 used,   829904 buff/cache

KiB Swap:  1512244 total,  1247116 free,   265128 used.   419072 avail Mem

after pressing 1:

top - 22:45:40 up 1 day,  1:14,  1 user,  load average: 0.16, 0.11, 0.18

Tasks: 225 total,   2 running, 223 sleeping,   0 stopped,   0 zombie

%Cpu0  :  1.6 us,  1.6 sy,  0.0 ni, 95.9 id,  0.8 wa,  0.0 hi,  0.0 si,  0.0 st

%Cpu1  :  0.8 us,  0.8 sy,  0.0 ni, 98.4 id,  0.0 wa,  0.0 hi,  0.0 si,  0.0 st

KiB Mem :  3936368 total,   283964 free,  2813716 used,   838688 buff/cache

KiB Swap:  1512244 total,  1247176 free,   265068 used.   414712 avail Mem

You can create/update your ~/.toprc file to make this the default by hitting W.
