pentium M performance

post #1 of 2
Thread Starter 
I am not much of an notebook kida guy. So it does not hurt me to ask for some refrences and opinions regarding the Mobile intel cpu line. Reasons for this are, that my father has a sony viao 1.7ghz 512ram and I was playing with it little bit today, and I remember he paid like 1700 for this less than a year ago, now I understand a good chunk of that was just for the name, anyways to the point. Is the pentium M processor built using Intel's netburst technology, essentialy making a 1.7ghz a pretty damn slow chip? If not, what is the opperating range of the Centrino class processor, anyone got any benches to share? How good is the processor line anyway? Would the Turion kick centrinos ass in the dark blindfoldned with a hand behinde its back? lol Im not an amd or intel fanboy, but I wouldnt mind hearing both sides, just throw me some facts.

Pentium M is a different technology than Pentium 4. Read this:
http://en.wikipedia.org/wiki/Pentium_M

Here are some of my results in SiSandra:

Desktop 1: P4 Northwood, 3.0GHz (stock), FSB 800MHz, HT, 2GB PC4000 RAM
CPU Arithmetic:
Drystone ALU 9017 MIPS, Whetstone FPU 3745 MFLOPS, Whetstone iSSE2 6588 MFLOPS

CPU Multimedia:
Integer 22969 it/s, Float 32371 it/s

RAM Bandwith:
Integer 4002MB/s, Float: 4000MB/s


Desktop 2: P4 Northwood, 2.2GHz (stock), FSB 400MHz, no HT, 768 MB SDRAM (not DDR)
CPU Arithmetic:
Drystone ALU 5820 MIPS, Whetstone FPU 1613 MFLOPS, Whetstone iSSE2 2945 MFLOPS

CPU Multimedia:
Integer 13370 it/s, Float 17179 it/s

RAM Bandwith:
Integer 982MB/s, Float: 981MB/s


Laptom: Pentium M, 1.8GHz (stock), FSB400MHz, no HT, 1GB PC2700 RAM
CPU Arithmetic:
Drystone ALU 7735 MIPS, Whetstone FPU 2495 MFLOPS, Whetstone iSSE2 3191 MFLOPS

CPU Multimedia:
Integer 17096 it/s, Float 18849 it/s

RAM Bandwith:
Integer 2297MB/s, Float: 2298MB/s

Thus, the Pentium M beats the older 2.2GHz desktop easily, but does not come close to the 3.0GHz Northwood (not surprisingly). Of course the 3.0 desktop has hyperthreading and a higher FSB.

Also, check this article for a comparison test. Of course, this is just one review, but it shows that the Turion beats the Pentium M on many fronts (not all). However, it's not a wipeout.

Hope this helps
