There were several benchmarks mentioned. I ran the nqueens program below on an Nspire CX II CAS in about 2.9 seconds. I really wish the Nspire had an RTC for more accurate measurements.
BTW, I'm using OS 5.1 which was released recently.

Code:

Define nqueens()=
Prgm
  Local a,r,s,t,x,y
  8->r
  newList(r)->a
  0->s
  0->x
  Loop
    x+1->x
    r->a[x]
    Loop
      s+1->s
      x->y
      While y>1
        y-1->y
        a[x]-a[y]->t
        If t=0 or x-y=abs(t) Then
          0->y
          a[x]-1->a[x]
          While a[x]=0
            x-1->x
            a[x]-1->a[x]
          EndWhile
        EndIf
      EndWhile
      If y=1
        Exit
    EndLoop
    If x=r
      Exit
  EndLoop
  Disp s
EndPrgm
