Intel Core 2 Duo E6400 2.13GHz = Which Intel Pentium D Processor?

[Holy Crikey]

Everything else being equal, and perhaps even the motherboard, since I
heard that on some motherboards, such as Intel's D946GZIS, you can
just swap between the Pentium D and Core 2 Duo procs, which of the
Pentium D proc would equal the Core 2 Duo E6400 2.13GHz in terms of
processing capability? I understand that the proc speed is pretty
much irrelevant when comparing, but I'm curious about the raw
processing/computing capability, everything else being equal. TIA.

For doing what? Check out the charts at

AFAIK, the only thing that will consistently beat the E6400 is an E6600 or
faster. Possibly an AMD FX-62, in an AMD platform (obviously).

Some of the other Intel processors (Pentium D 670, the EE 965, etc) may beat
the E6400 on some benchmarks, but overall, probably not. They'll also
generate much more heat, and around here, anyway, they'll cost more and are
much harder to find.

My comparisons of both cores running full bore for hours running my software
tests, showed the C2D 2.6 G is 1.75x faster than a PD 3G (both systems are
pretty similar ... a Dell 9100 and 9200). So, I would estimate the 2.13G
C2D to perform roughly like a PD at 3.7G. Obviously, it depends on the
tasks at hand. My tests are a mix of standard integer and floating point
code, not particularly optimized for any processor.
