choose trisquel_4.5.1_amd64.iso for Intel microprossesors [SOLVED]

Well I just wanted to add this to the forum, I know is a very nobie answer but I wasn't sure.
trisquel_4.5.1_amd64.iso works for Intel and AMD microprocessors alike. I just got confuse with the part that says amd64 on the iso name.
In the wikipedia you can find a little explanation of why the x86-64 is also called amd64: http://en.wikipedia.org/wiki/X86#Long_mode
To what understand AMD won the battle against Intel on implementing the most popular 64 bits' set of instructions, but I'm not an expert and I am kind of a lazy reader, so if somebody knows better please explain. See you all.
I am a translator!
I always thought the arch's name is amd64, because AMD was the first to bring out 64bit compatible processors (the Athlon 64). Maybe they also created some sort of standards for 64bit instructions, like IBM created a standard with the 386.

Intel moved its own way at 64 Bit Processors. The Itanium (sometimes called Itanic). Problem of it was that the 32Bit speed of Itanium was very slow. Intel refused to use AMD64 (a extension of x86) for quite a while till MS stated that there will be only one Win64 version. Intel then integrated their own Intel-64 extensions into their Netburst Architecture. Most parts of the Extensions are Compatible, only a few are missing or altered.

Now that we are talking about this, i have a question.
Does the i3,i5,i7 processors are x86 or amd64?
Or even different, do they count as new platform?

Those ones are x86 Compatible 64 bit Processors. I follow a bit Wikipedia
AMD64 was designed as Extension to x86. 64Bit Processors are able to run 32 and even 16 bit. For that the Processor changes his Run Mode to
Legacy Mode: In that he can run all "older" Runmodes (Real-Mode, Proceted-Mode, System Management Mode).
Long Mode:
64 Bit Mode: Used for 64 Bit applications on a 64 Bit OS
Compatibility Mode: Used for emulating 32 Bit Applications in 64 Bit Systems (the Applications sees a Protected-Mode).

Gee, now i'm having many questions.
The amd64 are x86 compatible, so if i run a 32 bits processor on my PC,
can i still use a amd64 without problem?
Then what is the difference between x86 and the amd64?
Should we all use amd64 on intel and amd bassed processors?

AMD64 is 99% the same with the Intel-64 Architecture. It's called AMD64 because AMD was faster than Intel in delivering. (And to Avoid confusion with IA-64 (Itanium)).
You can use a 32 and a 64 Bit Operating System on them (but you are limited to 4GB of Adressable Memory in 32 Bit Systems)
You can run a 32Bit Application on a 64 Bit OS, but you can't run a 64 Bit Application on a 32Bit Operating System.
Processors supporting 64 Bit:
Intel: Some Pentium 4, all since Core2Duo and Core2Duo based Celerons, some Atoms
AMD: All Processors since AMD64
64Bit Architecture has the Advantage of using more than 4GB of Memory and some improvements on the executing of Code.
As disadvantage the System is a bit slower (while running 64 Bit OS because you need more Ressources to manage Memory).

This architecture is also called x86-64 or x64 right? Maybe thats how it should be labelled, to avoid confusing users into thinking its AMD only.

For the same reason we should rename i386 since it's not Intel-only (and
gNewSense and Parabola should rename mipsel/mips64el, they even don't
support any MIPS CPUs with these ports). Our download page names it
just "64-bit", which is confusing since it doesn't support e.g. MIPS64.
(Another problem is that not all Intel CPUs are amd64 or x86.)
A link to a list of possibly supported CPUs would be a simpler solution
to this problem.
