FSB800: first impression and a look into the future

FSB800: first impression and a look into the future


It has been official since last week: Intel will increase the frontside bus to 800 MHz with the upcoming processors, even if this has not yet been officially confirmed . Until a few days ago, an increase to 666 MHz was officially planned, which should go hand in hand with the introduction of the Prescott manufactured in the 90nm process. 'Prescott' is the code name for the next generation processor core and will sooner or later replace the current Northwood core of the Pentium 4. But due to delays, this processor will only be available to us in the last quarter of next year. For this reason, Intel has to extend the service life of the Northwood core manufactured in 130nm and if the clock screw can no longer be turned, the CPU is given more power through other measures such as a drilled connection to the rest of the system>

This is why the Hyper-Threading technology, which was initially only to be introduced to home users with the Prescott, was preferred and has been active for the first time since the 3.06 GHz Pentium 4 was introduced. Together with the presentation of a 3.2 GHz Pentium 4 with Hyper-Threading, the chip manufacturer will create a complete product family with the said 800 MHz front-side bus next year. Have about thiswe have already reported in detail in the past few days. These Pentium 4 processors are offered with Hyper-Threading Support from clock speeds of 2.4 GHz.

P4 2,4 FSB800

On the basis of a 2.4 GHz Pentium 4 with FSB800, we would like to venture a first, limited view. We have a 2.4 GHz Pentium 4 with 18x133 MHz and 12x200 MHz compete against each other.
