the right processor

[geekaman]

Hi everyone,
I'me a comp science eng student(first year), and  a casual gamer.I'm going to buy a laptop and these are the points i needed clarification on-
1. T6500 vs P8600 vs P8700-which one would be the best processor ?
2. 3 Gb or 4 Gb-which one would be better for the 32 bit vista ?
3. Is the 64 bit vista recommended (wrt software compat,e.t.c)and if so,what ram should i have?

I would go with the Intel P8700 processor.

Since a 32 bit OS can only address 4 GB of memory I would do 3 GB because the video card will most likely have it's own memory. If you go over 4 GB of memory, Windows will only address 4 GB.

A 64 bit OS will be able to address 128 GB of RAM.

a 32 bit os cannot use 4gb usually.  Usually its 3.25, but it can vary.

A 64 bit OS will be able to address 128 GB of RAM.

Being able to use 4gb+ RAM is certainly an advantage with an X64 OS, but my Vista X64 system would likely have a heart attack with 128 GB.

Thanks a lot guys!

I really appreciate the info guys. It's all I needed to know for now.

Uhh is this your thread?

danielRay,

This thread was started by geekaman  and comments should b for his benefit. Next time, start your out thread if you need advice. But no harm was done.

By the way, Here is a link to a general review of  new CPUs in the market:
Intel vs. AMD:

They indicate that Intel may have the edge, for now.

Right, I get 3.5 for my tops on a 32 bit OS.

um... a 64-bit OS can address 2^64 bytes of information... that's 18,446,744,073,709,551,616, 16 Exabytes.

However most 64-bit Operating systems limit this:

Windows XP x64 Edition can use up to and including 128GB of RAM.

Windows Vista depends on the edition:
Vista Home Basic x64 can use 8GB, Vista Home Premium x64 can use 16GB, and
Vista Business x64 and Ultimate x64 can use 128+ GB. (although it can be made to use more then 128GB that configuration is not supported by MS) (although you'd be hard pressed to find a motherboard that supports it, anyway....)


Windows 7 64-bit, varies much like Vista.
Home Basic: 8 GB
Home Premium: 16 GB
Professional,Ultimate, and Enterprise: 192 GB


Of course for the high-end these aren't really "limits" that will be hit any time soon, and right now are merely the maximum amount of supported RAM (the lower editions are a software limitation purposely enforced by the OS).

BC_Programmer,
Question of the day!
Which recent Windows 32 bit OS can handle and make available
mover than 4GB of memory. And what CPU is used? 

[BC_Programmer]

Server 2003 I believe, with a processor supporting PAE.


I think.

[Geek-9pm]

You got it.
