Processor help: What numbers mean the best?

by Silpheed / January 24, 2006 11:07 AM PST

Hi! I'm trying to pick out a good gaming laptop, due to my portable needs. I've been trying to pick the best one for the best price: but I'm a bit confused on processing speeds. For example:

One Intel Pentium Processor offers 650+/3.4GHz
Another Intel Pentium offers 755/2.0GHz

The 1st processor seems pretty good. 3.4GHz. This one comes in the laptop that is cheaper.

The 2nd processor comes in a laptop that is more expensive. 755 over 650.

My question is... which is better? And I have a general idea about GHz, but not the other numbers. Anyone able to offer some light on the subject?

the 755
by 0wnz / January 24, 2006 12:28 PM PST

the 650 is a mobile pentium 4 processor, which is baisicaly a slightly modified p4. The mobile p4 makes too much heat for use in a processor and is generally a lower performance proccessor, even at a higher clock rate. The 755 is a pentium m meant for use in laptops, and is very power efficient. In terms of proccessor speed, I've heard that you can roughly double the speed of a pentium m(755) to compare it to a pentium 4(650). I cannot tell you which pentium m to get, but stay away from mobile pentium 4 proccessors in laptops.

What I've learned. No Pentium 4 laptops.

Your choice here. After a year or 2 they seem to be prone to crashing. You can get more time till this happens with a laptop cooling pad, but unless this laptop was free I would never consider a Pentium 4 in a laptop.

You'll have to ask around about this anomaly.

Thanks for the advice! I've heard I should always go Athalon or such over Pentium, but for some reason, a huge majority of laptops offer the Pentium chip instead.

I'll keep looking around then! And thanks for at least letting me know which would be better!

The answer to your core question
by mousepusher / January 29, 2006 6:12 AM PST

Dont be influenced by those with preferences. For every person I know who swears by AMD, I know another person who equally swears by Intel. Its all about making a truly educated choice. An Intel Centrino M 730 (although lower in model number) may be better than an M 735 because of its Execute Disable Bit (XDB) properties. In other words, at the hardware level, it is inherently stronger against malicious worm attacks because of its buffer overflow protection. Intel processor numbers are NOT a measure of their performance. The numbers are only an identifier as to which families they belong.

You can go to and download a full listing of their processor families on PDF. You'll need to first go to and download the latest version of Acrobat Reader if you havent done so already.

Copy and paste the weblink below (and I would suggest you add it to your favorites once you open it) to get an instant, complete, and current processor number listing directly from the Intel website:

By the way... yes, I am an Intel user, but dont let me influence you Happy
