V2000 Vs V2000z?

Hello,
I am buying a new compaq soon and I am still wondering if to get V2000 or V2000z. I really like the pentium M processors but in other hand Turions look good. I really need few advices about this. Let me tell you what im thinking to buy:

1) V2000

Pentium M 740 (1.73 Ghz)
14" Brightview Widescreen
Intel(R) Graphics Media Accelerator 900 - Celeron
256 Ram ( I will buy 1 gig from newegg once i get the notebook - cheaper)
40 Gig HDD ( will buy 7200 one separately )
8xDVD Drive
Intel(R) PRO/Wireless 2200BG & Bluetooth(TM)
12 Cell Lithium Ion Battery

Final price $857 After mail-in Rebate


2) V2000z

AMD Turion(TM) 64 ML-37 (2.0GHz/1MB L2 Cache)
14" Brightview Widescreen
ATI RADEON(R) XPRESS 200M w/productivity ports
256 Ram ( I will buy 1 gig from newegg once i get the notebook - cheaper)
40 Gig HDD ( will buy 7200 one separately )
8xDVD Drive
54g(TM) Integ. Broadcom 802.11b/g WLAN & Bluetooth
12 Cell Lithium Ion Battery

Final price $813 After mail-in Rebate

And here are my few questions for the people who know more than me :

Which is better between the 2 processors? The pentium M or Turion? Which is more stabile ( after or before the undervolting of the turion).. Which one produces less heat? Which one is a better power saver?

Then the video cards. Intel(R) Graphics Media Accelerator 900 - Celeron Or ATI RADEON(R) XPRESS 200M w/productivity ports? Are they both shared ? And which one has a better performance?

And my last question is about the Turion and using RMClock on it. Are there any risks for undervolting the processor, and unwanted effects and mostly is it a lot better than the pentium M 740 after the undervolting.

I really will appreciate any help here because I am debating with myself about which between these two to buy. I really want something that doesn' produce much heat , a good battery life and a good performance for some games as well. It might be a lot to want from a notebook but who knows. Anyways thanks in advance.

 

This seems like an easy one to me. The v2000z is over $50 less (so you could get a CD-RW drive or such, if you wanted), the Turion ML-37 is a lot more powerful than the Pentium-M 740 (plus more futre-proof being 64-bit), and the x200M is easily 3-4 times as powerful as the GMA 900 (the x200M you're getting is 32MB dedicated/96MB shared, while the GMA 900 is 128MB all shared, plus the x200M has a more powerful GPU).

As for undervolting, it is unlikely you could damage your processor - if it isn't getting enough power, your machine will simply give you a BSOD and shut down. Once you find the poper voltage settings, the Turion should have roughly equal battery life and heat to the Pentium-M, maybe even a little better, and is still a far moe powerful processor.

 

I second V2000z. That is very easy decision.

But I would like to add small correction. V2000z does not have any dedicated Video memory, but we can assign minimum 32MB shared memory to max 128MB(32,64 or 128). But because of ATI hyper memory feature It can take double of what we assign in Bios.
Means if you assign 128MB in bios, Video card takes minimum 128MB irrespective of it needs or not, but go max to 256MB if needed by video card.

And V2000z really benifits from DDR400 RAM as Video card uses shared memory, so you will 12-15% improvement accross the board.

And finally ML-37 is more powerful than 1.73 P-M, and it uses much less power in intermediate steps.

Typically ML-37 responds well for undervolting, 10x is around 1.25v (from default 1.45v), [email protected],[email protected],[email protected].
Those are average figures and you may verywell do better than that, as new processors do better than old batches.

And also ATI 200M is Vista approved as per ATI.( and I think more around 2 times powerful than Intel IGP).

 

Ah guys that helped me a lot. I just want to switch my Presario X6000 ( p4 630 3ghz , 1 gig ram, 80 gb 5400 hdd, ati x600 256) , because it is too big, weak battery life and mostly because it gets VERY hot , especially when gaming.

Also do you think that the newegg-ed kingston 1 gb 200 pin so-dimm 533 pc2 4200 memory will fit in the V2000z because I've read that it doesn't fit in some notebooks. And how about 7200 60 gb hitachi travel star (i think hdd will be fine though)

And like I said my main reason to get a new notebook is to deal with less heat. A friend of mine has Pentium M with centrino and the notebook gets barely warm. I am not sure about turions though - I hope it is the same. I just get nuts when my presario x6000 hits 65 - 70 C when I use more applications or even 70-75 for gaming - it is insane.

 

Current Turions use DDR1 memory, not DDR2, so you want 1GB PC2700 or PC3200 SODIMMs. Crucial is my favorite brand, Kingston is probably good too.

7200RPM HDs won't be a problem. There is a long tradition of swapping better HDs into HP notebooks .

Heat shouldn't be too big an issue, even before undervolting. Your P4 burns 3-4 times as much power as the Turion.

 

Heatwise, I do not think it is hot at all. Fan starts when CPU reaches 58-60 and drops to 50c in few seconds even at full load.

For typical browsing on battery fan never turns on( with the undervolting settings I have mentioned above).

HDD become somewhat warm and it is the case with all V2000, DV1000 series as it does not have great cooling.

May be you could swap your 80GB 5400RPM from old notebook.

As per memory, I would suggest OCZ DDR400 512MB x 2 from newegg. This is the fastest memory at CAS2.5 for V2000z sofar. All other memories are CAS3.0 (thought those are listed
as CAS3.0).

BTW I have Corsair DDR400 512MBx2 , though rated as CAS 2.5 as per newegg listing, it is actually CAS 3 at DDR400( SPD timing table).
