http://www.theinquirer.net/?article=19187 Is Intel's x86 dual-core based on Northwood? Prescott? P6? PM? The article mentions 3.2 GHz, which, if accurate, rules out P6 and PM. (Unless 3.2 GHz = two cores at 1.6 GHz... just kidding.) AMD's dual core is supposed to run slower than their single core. It looks like Intel hopes they don't have to underclock their dual core? -- Regards, Grumble |

It looks like Intel hopes they don't have to underclock their dual core? the dual core clocked at 3.2GHz that Inq lists would be the one they've been talking about for months--two prescotts stitched together at the pins. Intel has announced Prescott based, Prescott's successor-based, Pentium-M-based, and Itanium 2-based dual cores for 2005. That's just the one most people will care about--the first desktop model.

http://www.theinquirer.net/?article=19187 Yousuf Khan Newsflash: The Inquirer floats down out of geek hyperspace and acknowledges some everyday reality: "Intel's aggressive marketing of the kitemark and the Centrino brand has paid dividends for it. To many folk, wi-fi notebooks and Centrino means the same." Staff probably needs a hit of something or other to regain altitude. RM |

Given that they are already at 3.6GHz now and plan on getting to 3.8GHz before the end of the year, I would say that they are indeed downclocking their dual-core chips relative to the single core ones! ------------- Tony Hill hilla underscore 20 at yahoo dot ca |

Isn't that supposed to be the whole point of multi-core for both AMD and Intel ? In other words, to find ways to continue to improve cpu performance without having to rely solely on jacking up clock speeds ? -- Reply to Do not remove anything. |

Both AMD and Intel have already been doing lots of things to improve cpu performance other than only jacking up clock speeds. Multiple cpus on a die is one of many things they're trying. The reason people are wondering about how low the clock will be is that they hate sacrificing too much single-thread performance to get better total performance. Also, they want to know how much improvement in total performance that they're going to get. -- greg |

Both AMD and Intel have already been doing lots of things to improve cpu performance other than only jacking up clock speeds. Such as ? Take the AMD64 processors, for example. Multi-core would be the first significant change to the AMD64 architecture since the Opty 140 and 240 were released at 1.4 GHz. All we have seen in the meantime is a steady jacking up of clock speeds and there is nothing else on the horizon for the next 6 to 9 months. The situation has been much the same for the P4 since it first came out. Many small changes have been made to allow Intel to keep jacking up clock speeds, but the basic chip design has stayed the same. You could make an argument for the Pentium M as being Intel's effort to get performance at lower clocks and without needing a nuclear reactor in every home, but since you *still* can't buy a full-fledged ATX motherboard for Pentium M the point is pretty much moot.

Both AMD and Intel have already been doing lots of things to improve
cpu performance other than only jacking up clock speeds. Such as ? pipelining, OOO execution, bigger caches, faster caches, higher associativity in caches, fewer cycles for some operations, on-board memory controller, wider busses, better compilers, SMT, more registers, new instructions, more reservation stations, more ALUs, better branch predictors, ... Take the AMD64 processors, for example. Multi-core would be the first significant change to the AMD64 architecture since the Opty 140 and 240 were released at 1.4 GHz. All we have seen in the meantime is a steady jacking up of clock speeds and there is nothing else on the horizon for the next 6 to 9 months. Only Ghz can be changed without some significant redesign, so it's no wonder that within a short time span nothing else than Ghz will change. Stefan |
