Let's analyze some data. SuperCPU's 65816 is clocked to 20 MHz. It makes 3000 digits of π for 87 seconds (in PAL system). So the reciprocal of the normalized efficiency of CPU for 1 Mhz is 20*87=1740. 6809 at Dragons and Tandy Color computers is clocked to 1.78 MHz and it takes 1414 seconds for 3000 digits. So the reciprocal is 1414*1.78=2516.92 The latter value is about 45% bigger.
I add data for some other CPU:
6502 – ≈2800
z80 – ≈5000
80286 – ≈500
ARM1 – ≈350
8088 – ≈2000
68000 – ≈1200
