differences between cpus?

[mrweirdo]

I'm thinking about posibly geting a lower priced notebook around the $500-$700 range and I'm wondering what would be the best processor to get. I'm thinking more performance wise(not battery life) wich is best between Intel Celeron M, AMD Turion, AMD Sempron. Of corse if I went with intel I would probably buy from dell otherwise I have looked at hp and acer so far for amd based notebook options.

Side note I'm looking for wireless on my laptop and posibly runing a linux distro like ubuntu.

The Turion would top all of those for performance, followed by the CeleronM and and Sempron.

If you can afford a Turion notebook over a CeleronM, go for it. It's basically a Athlon64.
The CeleronM's are basically the same thing PentiumM's were a year and a half ago.
Sempron's are stripped down Athlon64's.

Pentium M: Intel's magical new mobile CPU. Low power consumption, high performance (roughly equivalent to an Athlon64 clock for clock)
Celeron M: Like the Pentium M, but less cache and no enhanced speedstep. Still performs extremely well compared to the P-M - not a bad chip at all if battery life is not of the utmost concern.
Turion 64: An Athlon 64 with more power saving technology. Battery life is not as excellent as the P-M, but still pretty good.
Mobile Sempron: Like the Turion 64, but with less cache. Comes in a lot of variants (32-bit vs. 64-bit, 128kb vs 256kb L2 cache). Generally performs very well, but less than the Celeron M. _Does_ keep the T64 power saving stuff, so it's not a killer on your battery.

So, in your case, you want a P-M or a Turion 64. Bad news is, the $500-$700 price range is going to make it very hard to find anything with those CPUs in it.

thanks for the good info. I realize that not much can be had for that price range and I may actualy wait a month - 3 months longer and go for an 12" apple iBook for the *nix factor and its sure to support all the hardware in the system unlike linux with a lot of pc laptops.

not true..or post ur sources.

look at the thermal specs for the processors, not some laptoplogic article that is comparing two completely different laptops. yes, they look similar on paper, but this is not a good way of comparing processor efficiency. instead it is just comparing the best acer made to a decent one. the newest intel chips fit in a 27w TDP, where the turion is a 35w TDP. that is close to a 30% increase in power use for the Turion compared to the pentium m. These are both extremely low power usages, however. in case you are looking for my sources, try intel.com and amd.com

OK, here's some counter-evidence:

THG also comments that the MT-34 ran ten minutes longer than the ML-34.

Current Problems with Direct Comparison between Pentium M and Turion

1. Lack of Turion Laptops for Comparison

2. Difference in TDP. Intel and AMD calculate this different so just comparing the numbers is invalid

2a. Difference in Use, as has been widely reported, Turion laptops do better (in terms of Battery Life) when they are not in constant use

In the end, it comes down more to Price... if you can't afford a Pentium M, then a Turion Laptop is -significantly- better than Celeron or Semperon

On the other hand, if you can afford the Pentium M price premium (around 200) there really is not a compelling reason to choose a Turion alternative...
