AMD planning 45nm 12-Core 'Istanbul' Processor ?

Intel had explored 64-bit extensions to X86 years earlier. (How could they not? CPU's are their business.) |

says... I suppose if AMD hadn't been around, there would have been a greater chance of Intel getting their butts whipped by some other architecture, instead of by AMD. What architecture? You grossly underestimate the x86 inertia. Yeah, I recall how years ago some nutcases saying things like the Pentium 3 (yes, the 3) was "already obsolete" upon release, because it did not support IA64, which was set to blow X86 out of the market when it was released. Of course, more sensible minds thought "Huh? It'll be more expensive, yet run all the software slower, since all the software is X86, so why would I want it?" |

And by trying to protect it, they basically screwed themselves. Only after AMD released theirs did they try to bring their x86 64 bit code out. MS had already done a version of windows for Itanium and weren't going to play Intels games at their expense. -- Want the ultimate in free OTA SD/HDTV Recorder? http://mythtv.org My Tivo Experience http://wesnewell.no-ip.com/tivo.htm Tivo HD/S3 compared http://wesnewell.no-ip.com/mythtivo.htm AMD cpu help http://wesnewell.no-ip.com/cpu.php |

None of that disputes what Keith or I have claimed. I think we're all on the same page, now. |

Yeah, I recall how years ago some nutcases saying things like the
Pentium 3 (yes, the 3) was "already obsolete" upon release, because it did not support IA64, which was set to blow X86 out of the market when it was released. PIII obsolete? Hmm...trivia of the day - what microarchitecture did Intel base the core on? And what microarchitecture does the core have little if anything to do with? |

The Pentium III was little more than a Pentium II with the L2 cache chips integrated on-die and running faster. The P2 was little more than a slot repackaging of the PentiumPro which was a completely new effort for Intel having nothing in common with the original Pentium and PentiumMMX. In many ways the P4 has nothing in common with the P3 or core, and looks much more like a dressed up, overclocked original Pentium. -- Robert |

The P4's netburst architecture was a dead end road, and not even cranking up the clock to 3.8GHz gave the performance people wanted. The core did not inherit from the P4, but was based on PPro/II/III architecture. |
