AMD Releases 12 New Chips at CeBIT
SuperDuG writes "AMD now offers three categories of processor for notebooks grouped under the Athlon XP-M brand. It labels them "desktop replacement," "standard," and the new "low-voltage". AMD plans to make a desktop replacement in the notebook computer market using the Barton Core, a technology designed to double the CPU Cache. Looks like yet another case of AMD being one-up on Intel."
Does anyone know what voltage the XP-M even runs on?

It says in the article than the 'low voltage' ones peak at 25 W. (For comparison, the higher-speed Pentium-M chips peak at 24.5W; the ultra-low-voltage Pentium-M chips peak at 7W. Plus they're likely way better at staying below the 'peak' values.)

And they're both still behind VIA and IBM on both power consumption and heat.
.75 and you get it's pentium equivalent. And they run as cool as a 486 (thereabouts). So they max out at 933Mhz (equal to about a 700Mhz pentium-III), they run air cooled with just a heatsink. That's just great.
VIA chips have a lot less processing power, but wow can you do some wierd and neat things with them. Multiply the Mhz rating of a C3 by
We all know how great the powerpc chip is for laptops, anyone who owns a Mac laptop can fill you in far more than I can.
I always thought the "big boys" were more concerned with raw cpu ops/cycle or Mhz than power and heat, at least there's a shift of views in both camps. This can't be anything other than a good thing, otherwise, I predict by 2060 if processors keep getting as hot as they have been, running your PC without a coolermaster "absolute zero cryogenic cooling unit" will cause nucleur fussion to occur inside your case. Hello miniature sun. That would be AMD's model, intel's would just vaporize everything in a wide radius.

Yeah, but AMD CPUs, because they don't use quite as huge a pipeline, aren't affected by L2 cache size like the P4. The 512k P4s were cache starved, where the smaller-cache Athlons weren't being held back by the cache size. None of this matters though if nobody puts them in computers though.
What about the Centrino processors released last night? 1.6GHz performing equal to that of a 2.6GHz P4?
;)
Actually, the Centrino 1.6 was faster than the p4 1.6. This links to the comparisons, choose Compare Performance.
It uses Mobile Mark 2002, with the p3/1.2 getting a 134, the p4/2.4 getting a 164, and the centrino 1.6 getting 189. Now just using Redneck Math(r) that would have a theorical p3/1.6 getting about 179. (compared to 189 for Cent1.6) It shows only a 18% increase in speed of the p4/2.4 over the p3/1.2. This is one reason I have been so disappointed that my dual p3/1.0 beats my p4/2.5 hands down.
My theory is that there really is no Centrino, and its really just a P3 with a bigger cache. I mean, whose gonna look inside the chips and compare them anyway? Its not like you can SEE them circuits
Ok, conspiracy freaks, you take it from here, please...
