I've occasionally looked at the stuff at mini-itx.com and wondered if those things could be used as farm building blocks. But the floating point performance was always unsuitable. Maybe the Nehemiah is different.

I have a Nehemiah 1Ghz sitting around -- hadn't thought to bench on it yet, but I'll hook it up quickly tonight and run one. Results to follow in two hours or so...

Scratch that -- it was sold to me as a Nehemiah, but it is model 8, stepping 9, and so is an Ezra instead... So, here at least are the results from a Via C3 Ezra 1Ghz, with FSB of 100Mhz:

Which represents a better than linear speed up over the 800Mhz C3, but doesn't inspire me to get this box set up permanently

My Dell 8600 laptop CPU info is:

TYPE: Pentium M (centrino)
SPEED: 1.7 GHz
L2 Cache: 1024 KB
L2 speed: Full, same as CPU
Memory 333 MHz DDR SRAM (PC2700)
OS: Windows XP PRO

This is a laptop system and according to Intel is supposed to be equivalent in CPU power to a P4 2.6 GHz.

I also have a P4 2.6 GHz machine that is actually much faster then the P M 1.7 GHz

The P M 1.7 GHz has a 2048k benchmark of 206.587
The P 4 2.6 GHz has a 2048k of 81.721

So why is the P4 is much faster?? or the P M so much slower??
I have check the speedstep function and the CPU is running at the full 1.7 GHZ

Maybe the PRIME software is more optimized for the P4 than the P M.

Also, are there "CPU heat" concerns with running Prime on my Dell 8600 laptop?

Read this thread for more info concerning Pentium-M and Prime95.

The main reason is, that the FPU hasn't been improved a lot over P3s (surely due to power saving reasons) and even if it would have a thoughput like P4 or Athlon it would be limited by clockspeed. SSE2 has been implemented and the capability of parallel FMUL/FADD. The not so fast L2 cache is another reason.

I'm sure that heat won't become an issue with Pentium-M if the laptop has a good fan. At work the fan of a Dell laptop with P4-M became noisy after the machine was running at 100% CPU for several weeks. But I'm sure there are also companies which build quality notebooks...
