Vào năm 1999-2003, AMD đã mở rộng kiến trúc 32 bit này thành 64 bit và gọi nó là x86-64 trong các tài liệu ban đầu và sau đó là AMD64. Intel đã sớm áp dụng các phần mở rộng kiến trúc của AMD dưới tên IA-32e, sau này được đổi tên thành EM64T và cuối cùng là Intel 64.

30/01/2012 · Show activity on this post. From what I've read extended Memory 64-bit Technology (EM64T) is Intel‘s implementation of AMD‘s AMD64 and the differences between the Intel64 and AMD64 are: EM64T’s BSF and BSR instructions act differently when the source is 0 and the operand size is 32 bits.

First of all, there is no Intel64, Intel refers to the AMD64 instruction set on its CPUs that it licenced from AMD as "x86-64". I'll give a (very) brief history of the x86 architecture: Intel developed the "x86" architecture which was a 16-bit arc...

25/03/2015 · AMD64 is the real 64 bits architecture that AMD created and intel licensed it and uses it even today (just as AMD had the license to use x86 on the 32 bit CPUs). x86_64 far as i know is nothing more than a 32 bit CPU that can address the extra memory that a supposed 64 bit system need (so like a 32 bit system that recognizes and uses more than 4GB of RAM).

Later, it was adopted by Intel,Now Intel calls it Intel 64 AMD64. AMD64 architecture adds 64 bit registers on IA-32, and is compatible with early 16 bit and 32-bit software, which makes it easy for existing X86 based compilers to convert to AMD64 version. becauseAMD64 and intel64 are basically the same,Many software and hardware products use a term that does not tend to …

D'après ce que j'ai lu, la technologie de mémoire étendue 64 bits (EM64T) est la mise en œuvre d'Intel d'AMD64 d'AMD et les différences entre Intel64 et AMD64 sont: Les instructions BSF et BSR d'EM64T agissent différemment lorsque la source …

the AMD64 architecture was positioned by AMD from the beginning as an evolutionary way to add 64-bit computing capabilities to the existing x86 architecture, as opposed to Intel's approach of creating an entirely new 64-bit architecture with IA-64. The first AMD64-based processor, the Opteron, was released in April 2003.

09/08/2012 · IA-64 is the Intel Itanium Architecture. This is a Very Long Instruction Word (VLIW) processor instruction set. x86_64 is the normal 64-bit architecture that is used by processors inside every laptop / desktop in today's computers. This processor is a dynamic processor. The main difference between these two is that.

09/03/2007 · Here’s the answer from Answers: Extended Memory 64-bit Technology ( EM64T) is Intel ‘s implementation. of AMD ‘s AMD64. During much of AMD’s history, they have produced processors patterned after Intel’s, but, in an ironic twist of computing history, AMD64 has been adopted (under the name EM64T or IA-32e) by Intel—the original creators of the x86 ...
