Today, I had the opportunity:

Fast real notebook vs fast Pseudo "notebook"

Pentium-M vs Desktop CPU with Hyper Threading and 3.06 GHz



Notebook Acer Travelmate 663 LMI 512 MB RAM
1.6 GHz Pentium-M...............................4:35

Notebook Fujitsu Siemens Amilio 1024 MB RAM
3.06 GHz Pentium 4 HT.........................4:49

Notebook Acer Travelmate 802 LMI 512 MB RAM
1.5 GHz Pentium-M...............................4:54

Notebook Acer Travelmate 800 LCI 512 MB RAM
1.3 GHz Pentium-M...............................5:25

Desktop 512 MB RAM
Ahtlon +2500........................................7:06

Notebook Acer Travelmate 634 LCI 512 MB RAM
1.8 GHz mobile Pentium 4M..................7:14

Desktop 512 MB RAM
Athlon +2000........................................7:30

Notebook Gericom Hummer Advanced 512 MB RAM
Athlon +2500........................................8:11

Notebook 512 MB RAM
Athlon +1500.......................................12:40

Fujitsu Siemens Desktop 256 MB RAM
Celeron 1.6 GHz...................................16:17

Notebook Gericom Silver Seraph 256 MB RAM
mobile Celeron 500..............................33:11


How much the 1024 MB of the 3.06 GHz Pseudo "Notebook"
influenced the test is not clear by now

The bad constructed P4 was surprising fast.
At least, a little bit faster than a 1.5 GHz Pentium-M

When even the Pentium-M 1.6 GHz is faster than a 3.06 GHz P4 HT,
the new Dothan will make the P4 complete obsolet.

And what do the numbers represent?

If you ran some benchmark/workload,
please tell us what it was and how
you ran it.

Second, your conclusion is patently
incorrect, since it appears to be
based on one benchmark/workload.

Clearly, the Pentium M's have an
advantage for any workload that
does not fit into a 512 kb L2
cache.

On the other hand, anything that
fits in a 512 kb cache and does
not stall the pipeline should run
faster at 3+ GHz than at 1.6GHz.

Third, larger L2 caches will also
start appearing with Prescott, I
believe 1M L2 initially, not to
mention Extreme style chips with
2M L3 on chip. So it's too early
to pronounce the P-4 dead.
