Question amd or intel, which iso


I have a Dell Inspiron Laptop 1545 with Intel 64bit processor. Is there a problem if I try to install an ISO that is listed for the AMD processor vs Intel?

Hi,

Are you talking about amd64 vs x86_64?

If so: Nope, no problem at all. amd64 is a term used for 64 bit platforms (although you also see x86_64). I do believe Ubuntu uses i386 (32 bits) and amd64 (64 bits), both can be used for amd and intel processors.

Hope this helps

The AMD64 processor instruction set is used by both AMD and Intel processors.

The reasons are historical. Intel were first to market with 64 bit processors based on the old Intel *86 design, in 2001. The instruction set was called IA-64 and the processors, much delayed and re-named, were called Itaniums but they failed to catch on. In 2003 AMD launched 64-bit processors with their AMD64 instruction set. They were popular. So much so that Intel launched processors implementing AMD64 in 2004.

More info on Wikipedia here and here.

The AMD64 architecture is correct for your Intel 64bit CPU. If you have a choice of 64 bit architectures, then the Intel choice (IA64) is wrong for your CPU.

The architecture your cpu has is named "AMD64" by AMD, and named "X86_64" generally and named "EM64T" by Intel. The name doesn't matter. Binaries with any of those architecture names are all the same (correct for your laptop) thing.

Intel also makes a 64bit CPU with a different architecture named "IA64" and Linux binaries are available for IA64 and those will not work in your laptop.

The Itanium processors (IA64) were in no way based on the old x86 (IA32) architectures. Intel planned a total break with backwards compatibility for thir 64-bit CPUs. The first models could run IA32 code though a software emulator, and they really sucked at it. Later Intel integrated hardware features for better IA32 support, but the IA64 architecture as such is not related to IA32.

Thanks for the correction TobiSGD

Now it makes sense that the IA64 did not catch on.
