I'd be interested to see that benchmark. A ~3 GHz Pentium 4 sounds like a good reference point for single threaded performance since it's a reasonably modern OoO microarchitecture and reflects the moment that clock scaling stopped.

With a smaller cache, a less efficient branch predictor and only SSE for SIMD, I'd be curious to see the benchmark too but I'd be surprised if it was close.

I don't know if the RAM bandwidth being much lower would have an impact on CPU benchmark though.
