Is interesting- great reading!
No suprise though, in light of other stuff I've read on the subject!

It is amazing, especially considering that the Pentium M's execution units are no more powerful than those found in the Pentium III (with the exception of added SSE2 stuff).

There are a couple things that can explain why the Pentium M performs so well. The L2 cache, in addition to being huge, is also very low latency compared to Pentium 4 and Athlon. I think L2 latency is something like 10 cycles for PM, compared to 18 for Athlon 64 and almost 30 for Pentium 4 (ballpark figures). PM's front-end is also pretty efficient due to a very advanced branch predictor and an out-of-order execution engine that can keep track of more instructions. PM doesn't have much more computing silicon, than P3, but it uses its execution resources much more efficiently.

Arstechnica has some good articles on the Pentium M.

I hope Yonah can do better with floating point. DivX encoding still isn't on par with Pentium 4 and Athlon.

Pentium Stationary Mobile Procesor? (Pentium PSMP?)
Well. The day I see Pentium Ms in our desktops is the day I see a new era in overclocking mobile processors.

SSE/2/3 can take advantage of uOps fusion in Yonah, and FP has been severely uprated. Do a google search for 'Yonah digital media boost' for a lot of articles.

I think the multimedia performance will be quite good.

I have a 1.13 PIII.....

Hmm...

Anyone notice that in several benchmarks, the overclocked systems (especially the 16x160 system) turned in 0s?

THG didn't even mention it, but showed it in the graphs. I'd just take all of this with a grain (or a whole container) of salt...

Still, I can't say that I haven't looked at a P4P800-VM (with CT-479), and a Pentium M (don't know which speed grade, though) as my next system

wow, thats really interesting that the p3 line was actually better, but instead intel followed the trend of "cpu's sell by clock speed" and left the pIII behind.

so what is yonah like? is it anything like the p4 or p3(pm)?

i know yonah is dual core, but dual core what.

Yonah is a dual-core Pentium M with some enhancements, IIRC. Also, it uses the 65nm process, so the chip'll be smaller (per core) and probably cooler running (again, per core).

There'll also be a single-core Yonah (for cheap systems), and a server version of Yonah.

Same here, my 4 yr old Dell is running a 1.13 PIII Tualatin. I'm amazed still at how capable it is. If only the system would accept more than 512 ram.

I have a 600MHz Pentium 3 in one of those "Slotket" formats (Cartiage?)

ya we had a p3 500mhz slot loader, but my bro fried it trying to edit maps on warcraft 3.

ah, ok so the yonah is just 2 pent m's on one die, and on a slightly smaller die.
