Before saying the expected words about the higher performance level of the new Pentium 4 570J processor, we’d like to put an emphasis on the qualitative changes in the Prescott core this CPU is the first representation of. Particularly, this processor is the first Pentium 4 to be based on the E0 stepping of the Prescott core. This new core stepping is going to steadily find its way into all 500-series Pentium 4 models, giving these processors the support of the Execute Disable Bit technology as well as Enhanced Halt Mode C1E and Thermal Monitoring 2. What does it mean to us, humble end-users? The OS with its applications can now be protected against malicious code, the idle heat dissipation of the Pentium 4 becomes lower, and the performance drop won’t be as great as before at overheat.

Besides that, the introduction of E0-stepping Prescott cores means a growth of the overclockability of the Pentium 4 series – overclockers should enjoy this fact much. Thus, junior Pentium 4 models should be able to conquer frequencies above 4GHz after transitioning to the Prescott of the E0 stepping. We guess that’s good news for all PC enthusiasts.

As for the performance proper, the growth of the clock rate of the Pentium 4 570J processor to 3.8GHz certainly added more competitiveness to it. Now we can’t say AMD’s Athlon 64 series is better in terms of performance. Yes, the Athlon 64 3800+ and the Athlon 64 4000+ have no rivals in games, in data compression and computational tasks, but there’re still a lot of tasks, for example video processing and digital content-creation applications, where the Pentium 4 570J is superior. So, before voting for a particular architecture, make certain about the applications you’re going to use it in.

Still, we’re going to show you an averaged performance diagram with information about the prices of the processors that took part in our today’s tests.

As we see, the Pentium 4 570J can be viewed as a worthy competitor to the Athlon 64 CPUs. Meanwhile, since the Pentium 4 Extreme Edition 3.46GHz looks bad against the newcomer, we consider the Athlon 64 FX-55 as the fastest processor today.

According to Intel’s current plans, the Pentium 4 570J is going to remain a CPU with the highest frequency for a long time – at least throughout the next year. Instead pushing the clock rate above 3.8GHz, Intel’s going to add more performance to its processors by increasing their cache memory and introducing dual-core architectures. Thus, it’s quite possible that the Pentium 4 570J will remain the fastest CPU from Intel in some applications for very long. At least we don’t have much hope that Intel’s future processors on the Prescott II core or the dual-core Smithfield CPUs will push the performance bar of desktop computers much higher above.
