What is better x86 or x64 for windows 7?

Question

I'm running a
4GB DDR2
intel core 2 quad CPU 2.33 GHz
64bit OS

what'd would run faster? and does x86 mean 32 bit os?

Answer 1

X64 is better if you will use more than 4GB of RAM



X86 means 32 Bit

Answer 2

In 32-bit Windows, the OS will map video card addresses to the top 3 to 4GB, so you will "lose" at most 1GB of your 4GB of RAM. (there's a way to use it, but I only know of 1 app that uses PAE, besides, there's also a 2GB per app limitation that also needs to be avoided



In 64-bit Windows apps can use all the RAM the OS allows (16GB in Home premium, 192GB on expensive editions). Most apps compiled for 64-bits won't feel faster, 32-bit apps won't feel slower either. Old 16-bit apps (MS DOS, Windows 1 to 3) won't run.



x86 can be either 32-bit or 16-bit, but almost always means 32bit. The first CPU in the x86 family was the Intel 8086. (The first IBM PC used the 8088 which used cheaper 8-bit motherboard parts).

Answer 3

Yes, x86 is 32bit OS.



32bit architecture has a memory access limit of 4GB. This permits you to use about 2.75-3.5GB of RAM after IO reservations. 64-bit architecture can address 16 exabytes of memory, or more than 4 billion times that of its precursor. Windows 7 permits from 8GB to 192GB of physical memory to be accessed, depending on the version.

Also running a 64-bit OS include enhanced security with hardware-backed DEP, Kernel Patch Protection and mandatory driver signing.

Answer 4

64 bit does not run much faster and programs for it are scarce, I run 32 for this reason, 64 bit programs are slowly being written but the programmers stick to 32 bit because that is where the main users are.

And Windows7x64 will only use 3.8 gigs of RAM
