x86 and x64

[XxDj_zEuSxX]

Hi guys I have a kind of a dumb question, what does "x86" and "x64" mean? Thanks

[Shd0w2]

X86 IS 32BIT if I remember correctly

x64 is 64bit

[Enderman]

x86 means 32 bit computing, x64 is 64 bit computing

http://en.wikipedia.org/wiki/X86-64

basically x64 is 2 times as powerful as x86

Thanks guys, but does it have a "specific" meaning? I mean 86 or 64 what?

It refers to the bus width architechure on a processor. x86 = 32bit ; x64 (x86-64) = 64bit.

 

Edit: It also involves ram as well. system ram is usually x64 these days. vram can be anywhere from 128-bit to in excess of 386-bit (approx).

my guess is that it has something to do with binary

[Morpheus]

what's x79 then, saw something like that before

I think you're referring to an Intel chipset. ie: the new x99 that will debut with Broadwell

yeah nvm lol silly question

[PathfinderNC]

yeah nvm lol silly question

it's an understandably confusing naming system

Isn't the X99 chipset debuting with Wellsburg?

 

Which is Haswell - E

I may have it wrong. Haven't heard about Wellsburg, which may be why.  . . . I thought Haswell-E/Devils Canyon was z97?

That's fine.

X99 is Wellsburg : Haswell - E

Devils Canyon/Haswell refresh is z97

 

Though Broadwell - E will also be X99.

[PathfinderNC]

oh so the x99 chipset is codenamed Wellsburg? That was the disconnect. Thanks

Sorry, but this is not right.

 

x86 are all CPUs there are compatible with the 8086 and they can have a 16, 32 or 64bit bus with (maybe more in future).

 

x86-32 (sometimes called IA-32 or i386) are x86 CPUs with 32bit extension. Some People call it just x86, but this is not exactly.

 

amd64 (sometimes called x86-64, Intel 64 or x64) are x86 CPUs with 64bit extension. All amd64 CPUs are backward compatible with x86-32 CPUs.

In Linux, you can get the RAM expand-ability of 64 Bit using the 32 Bit PAE (Physical Address Extension) Kernel. I find myself still running 32bit PAE over x64 since most software and libraries are still 32 bit.
