Intel to Increase Stages in Prescott

Posted by CowboyNeal on from the massive-pipelining dept.

Alizarin Erythrosin writes "Further contributing to the MHz Myth, The Register and ZDNet are reporting that the new P4 core, codenamed Prescott, will have a longer pipeline then Northwood. No official numbers have been released, but The Reg is saying an Intel spokesman said that 30 stages seems to be a reasonable estimate. As most of us know, a longer pipeline can lead to slowdowns in the form of branch mispredictions and pipeline stalls. 'And just as the PIII proved faster than the early P4s in some applications, it's likely that Northwood will similarly prove faster than Prescott, which has clearly been designed for speeds of the order of 4GHz.'"

    it's still on the agenda.

    a trans-afghan pipeline has been encouraged by the us for years preceding the latest invasion of the country. it may never be built, but it is still being pushed by the US. There has been news trickling in fairly steadily in the past two months about this. eg from times of india jan 12

    the kazakhs HAVE a good deal of oil/gas - it needs to get south and west. maybe you're referring to the BTC pipeline project that replaced the first trans-afghan pipeline plan.

    the idea put forth by the "conspiracy nuts" is that the US had an interest in occupying the region because their presence means they can fund and participate in the installation of new export infrastructure (like the BTC, in which US-based Unocal is involved). The war in Afghanistan meant bases in neighboring countries like Uzbekistan, Pakistan, and Kyrgyzstan, which allows for a permanent regional presence.

    it doesn't really matter where the pipeline runs -the US couldn't have participated as easily if it hadn't established a presence.

    maybe the conspiracy nuts should hold off on the apologies after unocal donates a portion of their profits to the poverty and war-stricken afghan people, or towards the all-too-modest $160 million reconstruction plan. (To put this into perspective: this doesn't even approach the size of the defecits some of the US' state budgets run).
