Pentium 4 with 2.4 GHz in the test: The new front runner


To conclude this article, we will only briefly talk about the innovations that await us in the near future. In the first place is certainly the Pentium 4 with a front-side bus raised to 533 MHz, which is to be presented later this month. Of course, nothing has been learned from Intel itself on this matter. The only thing that is clear is that the processor will be based on the Northwood core and will only differ from the current Pentium 4 in terms of the higher front-side bus. With the new Pentium 4, a new mainboard is unfortunately required that can deliver a corresponding FSB of 533 MHz (133 MHz QDR). Intel itself has the i845-E with DDR SDRAM support and the i850-E for Rambus in its program. The i845-E is mainly based on Intel's new Southbridge, the ICH4 (Input/Output Controller Hub) on the new mainboardsto be found, which then bring, among other things, direct USB 2.0 support with them. With the i850-E, on the other hand, you will find the combination with the ICH3, which does without USB 2.0 support. As far as the northbridge is concerned, like its predecessor, the i845-E will only support memory according to PC2100 (PC266) with a clock rate of 133 MHz. Faster modules according to PC2700 (PC333) as they are currently on the rise will not be able to be operated with their clock of 166 MHz. The i850-E, on the other hand, will support the current PC800 Rambus modules as well as the new modules with a clock rate of 133 MHz (PC1066), which promise a significant increase in performance in the high-end area.

In the course of this year, Intel would like to increase the clock speed of the current Pentium 4 up to 3.0 GHz. As intermediate stages on the way there, we will of course see numerous intermediate models. All Pentium 4 processors up to the 3.0 GHz model will still be based on the Northwood core. In the longer term, the Northwood core will be replaced in the second half of 2003 by the Prescott core, which is already manufactured in 90 nm. Further innovations of the processor will also include the Hyper-Threading Technology, which was introduced together with the new Xeon MP processors. Two processors that are independent of one another are simulated within one processor, so that they can be used more effectively. This technology should of course also benefit desktop applications.
