i dont get it....

[freaky88]

why is 64 bit named x64 but 32 bit is named x86?!

 

[unifex]

Oh, mostly for historic reasons, going back to the 8086 Intel processor. Since then and until I think Pentium Intel names for their processors always ended in 86. So then once the numbering system was retired, people kept the x86 notation for this particular type of processor architecture. 64-bit processors are different and for them x64 seems only logical.

oh...so thats why i piucked x86 and it says that im not on the right os LOL....

# x86
Originally this code referred to Intel's x86 series of CPUs (eg. 286, 386, 486) but now refers to the underlying architecture and instruction set that handles 32-bit integer operations in a modern desktop CPU.

# x86-64
This is AMD's 64-bit update to x86 - this instruction set architecture contains additional features beyond just having 64-bit general registers.

# x87
Originally this code referred to Intel's x87 series of co-processors (eg. 8087) but now refers to the underlying architecture and instruction set that handles floating point operations in a modern desktop CPU.

# XRGB
A surface format that has the same file size as an ARGB surface but contains no alpha components in the pixels.

Gosh, now I didn't know that. Come to think of it I don't think I know it now! In fact I don't know what it is I don't know as I don't know it!
Oh I'm going for a walk with my dog, I can understand that!

Baby's back
Dressed in black
Silver buttons all down her back
High low, tippy toe
She broke the needle and she can sew

Walking the dog
just a walking the dog
If you don't know how to do it
I show you how to walk the dog
C'mon now c'mon

Just to add another level of precision...

The CPUs commonly referred to as 286, 386 and 486 (along with their variants) were actually 80286, 80386 and 80486 respectively.
