Yes, but your post said that it was 8.1 times faster than a 12-clocker at the same clock speed. So at 12 MHz, it would run at 8.1 MIPS.

You posted a note that the claim was 8.1 times faster than the original 8051 at same clock frequency. That means that it needs about 1.5 clocks/instruction.

You posted a note that the claim was that it could run at up to 300MHz.

So, in conclusion, it would manage about 300*8.1/12 or 202 MIPS.

It was your claim that would have a maximum speed similar to a 25MHz one-clocker, but a 25MHz one-clocker would manage 25 MIPS, while the earlier two claims would indicate a way higher top speed.

So I did ask how you made your computations, since your computations did not match the original claims you posted. No need to tell me what a 12-clocker is.
