Intel parle des CPUs 64 bits d`AMD

Indice de fiabilité : 8/8 (Incontestable)


En attendant notre article sur le CeBIT qui est en cours, voici une petite news insolite : Qui a dit qu'Intel ne parlait pas d'AMD au sujet de l'IA32e (ou EM64T), copie quasi-conforme du jeu d'instruction AMD64 ? Nous avons en effet trouvé sur cette page deux questions en relation directe avec AMD dans la FAQ d'intel, un grand moment :

Q9: Is it possible to write software that will run on Intel's processors with 64-bit extension technology, and AMD's 64-bit capable processors?
A9: Yes, in most cases. Even though the hardware microarchitecture for each company's processor is different, the operating system and software ported to one processor will likely run on the other processor due to the close similarity of the instruction set architectures. However, Intel processors support additional features, like the SSE3 instructions and Hyper-Threading Technology, which are not supported on non-Intel platforms. As such, we believe developers will achieve maximum performance and stability by designing specifically for Intel architectures and by taking advantage of Intel's breadth of software tools and enabling services.

Q15: Does Intel's 64-bit extension technology include support for AMD's 3DNOW!* instructions?
A15: No. Intel's IA-32 architecture does not support the 3DNOW! instruction set today. This will not change with the addition of our 64-bit extension technology.

Bref, aprés avoir pompé le jeu d'instructions d'AMD, Intel conseille fortement aux developpeurs de coder sur la plateforme Intel pour l'utilisation de l'AMD64, un comble...
