What architecture does amd have?

Strictly speaking, modern CPU is essentially RISC processor 86-64, also called AMD64, and its Intel version is called EM64T (just another name), which is a 64-bit CPU architecture extended by AMD on the basis of IA32. Intel can use it because of the cross-patent licensing between Intel and AMD. X86-64 is a new architecture adopted by AMD in its latest Athlon 64 processor series, but this processor architecture is IA-32, and some extensions are made on the basis of IA-32 architecture to support the application of 64-bit programs and further improve the computing performance of processors. Compared with Intel's 64-bit server processor products, An Teng and An Teng 2 series processor products, x86-64 has the greatest advantage of being fully compatible with previous 32-bit x86 architecture applications, thus protecting users' upfront investment. Intel's An Teng and An Teng 2 series processors need additional software or hardware to achieve compatibility with previous 32-bit programs, so IA-32 (x86-32) and x86-64 belong to x86, that is, Intel's 32-bit x86 architecture, such as Intel's 32-bit server Xeon processor series and AMD's full range. VIA's full range of processor products belong to x86 architecture. IA-64 architecture is an IA-64-bit CPU architecture developed by Intel and HP * * * in order to comprehensively improve the computing performance of previous IA-32 processors. It is a brand-new processor architecture specially developed for the server market. It abandoned the previous x86 architecture, thinking that it seriously hindered the improvement of processor performance. Its initial application is Intel's An Teng (An Teng) series server processors, and now the latest An Teng 2 series processors also adopt this architecture. Because it can't solve the compatibility with previous 32-bit applications, its application is greatly limited. Although Intel has taken various soft and hard measures to make up for this deficiency, with the full investment of AMD Operon processors, the prospects of these two processors based on Intel IA-64 architecture are not optimistic.
