Comparing Intel and AMD

Some tools (like CPU-Z) might find out that information. We can assume, that the FSB runs at 133 MHz (*4=533), since all models I know, which had 2.8 GHz and Gallatin core (should be the one with 512 kB L2), also had FSB533.

BTW, CPU-Z or CPU Info etc. could even tell something about memory timings. But this could depend on if they know the chipset.

It's a Dell PowerEdge. And there don't seem to be any tools for Linux AFAIK.

Then it is very likely, that the FSB is running at 133 MHz. As far as I can see, only the 1MB L2 Xeons (Nocona) have FSB800 in the PowerEdge servers.

So FSB800 + 2x1MB L2 + unbuffered RAM (likely with very good timings) push the Pentium D to being rather effective in running Prime95 (at least according to the results presented in the benchmark thread).

Sounds reasonable. I run work-related simualtions on that machine all the time and a 2.6 GHz ordinary P4 Northwood with PC3200 unbuffered easily outperforms the Xeon machine. But I guess, when accuracy is more important than speed.....

I would be interested to see if there is a comparison between Pentium D and dual Xeons on identical setups, i.e. same FSB, same L2 cache etc, same RAM timings etc.
