As already mentioned, with the introduction of the new Pentium 4 models the front -Side bus increased to 533 MHz, the underlying Pentium 4 processor architecture has not really changed much compared to its predecessor. The new Pentium 4 is also based on the 0.13µm Northwood core, which has a 512kb cache and which we have already looked at twice in the past. For this reason, we do not want to go into detail about Intel's NetBurst architecture of the Pentium 4 at this point and refer to our older article , which is still completely up-to-date in terms of architecture. The following table gives an overview of the current processors from Intel and AMD. We did not use the old Pentium 4 with a Willamette core, which was still manufactured in 0.18µm, for reasons of topicality, since Intel itself is already the end for all based on itPentium 4 processors.

As we can see, the differences are really not that big. As already mentioned, Intel also uses the Northwood core in the new Pentium 4, which is based on Intel NetBrust architecture, which was designed in particular for high clock rates and therefore can only develop its full performance with a high processor clock. In this context, Intel often had to put up with the criticism that the introduction of the Pentium 4 merely boosted the clock frequencywanted without breaking new speed records. The critics are certainly right about one point: A Pentium 4 running at 1 GHz would be significantly slower than a 1 GHz Pentium III or AMD Athlon. At a clock rate of 2.4 GHz, which the Pentium 4 with Northwood core achieves without major thermal problems, the result is completely different. When the 2.4 GHz Pentium 4 was introduced on April 2, Intel casually increased the processor clock by 200 MHz and can now add another 133 MHz to the 2.53 GHz Pentium 4. In view of these big steps, it should be clear that Intel has left its biggest competitor, the AMD Athlon XP, well behind. Since AMD was only able to add 66 MHz to the Athlon XP 2000+ with the introduction of the Athlon XP 2100+ with a real processor clock of 1733 MHz, the two fast processors from Intel and AMD are currently no less than 800 MHz apart. From Intel's point of view, the presentation of the Netbrust architecture on November 20th, 2000 was a resounding success - or has become one in the meantime. This architecture, which has already been mentioned several times in the meantime, can be outlined with six key words, which we already discussed in detail in an earlier article:

So if you are using the 533 MHz Pentium 4 expected revolutionary innovations, should therefore be a bit disappointed. Nothing has changed in terms of processor stepping either. At the moment there is only the nB0 stepping from the Northwood core, which is equipped with a total of 23 known errors.

However, by chance we noticed a visible change to the classic Northwood. The SMD resistors on the underside of the Pentium 4 are now attached with a different material. While the 400 MHz Pentium 4 2.4 GHz uses a silver material, all 533 MHz Pentium 4 models are equipped with a gold material.

The small difference between FSB400 and FSB533 processors

How Intel informed us however, this is a normal change within the framework of the usual further development. However, according to Intel, this modification does not result in any noticeable improvements.

All in all, the increase in the front Side bus on 533 MHz is the only real change in the new processors. But why should this increase the performance of the entire system? It has already been shown in the past that the Pentium 4 benefits greatly from the high bandwidth of the system bus. With a front-side bus of 400 MHz, the theoretical bandwidth is 3.2 GB per second. The Pentium 4 can communicate with the memory controller, the Memory Controller Hub (MCH) at up to 3.2 GHz, via which the AGP bus and the memory bus, among other things, are addressed. With a front-side bus of 533 MHz, such as the new Pentium 4 brings with it, the theoretical bandwidth increases by a good 30 percentand is thus a full 4.2 GB per second.
