Hardware, Embedded Systems OSNews recently linked to several articles on the two remaining big iron RISC based platforms still alive and kicking, something of great interest to myself both in a professional capacity and for personal reasons (I wouldn't be an avid OSNews reader and poster if I wasn't into non mainstream architectures).

Intel stopped making new CISC processors with the introduction of the Pentium Pro.

Modern Intel processors are RISC. They use a lot of transistors in their chips to translate the CISC instructions into something their chips can handle. Sure it's all one big chip, but the x86 ISA is created by essentionally hardware emulation.

If it was not for the requirement to keep compatibility with Microsoft's Operating System then x86 would of been dead a long time ago. There is no advantage to it in any way shape or form except for the advantages of being backwards compatible and people are familar with it.

No, modern x86 cpus are still CISC, yes they have a RISC-like core but it doesn't change the fact that they still come with a complex instruction set.

The Itanium however is clearly a RISC cpu and is advertised as such:
