The Prescott based cores have come under fire over the last few months, with extremely high temperatures, thermal throttling issues surfacing - the 0.09 micron based Pentium 4's seemed to be a plague to avoid.
Intel however has done some homework on the latest introduction of the new Extreme Edition on the Prescott architecture. Prescott does allow a reduction in voltage and die size, which results in a cheaper core, however, the main claim to fame of the Pentium 4 Extreme Edition was the L3 cache but now this has been removed in favour of using a L2 cache size of 2MB.
Having said that though, the Pentium 4 Extreme Edition at 3.73GHz makes a good impression - with the Prescott core we expected super high temperatures in the 60+ range but we were very surprised with a maximum of 52deg Celsius under full Prime95 load. We also ran Throttlewatch in the background to log any thermal throttling that the CPU might be running. We recorded a 0% TM1 throttle, indicating the CPU stayed within thermal limits which would seem to indicate that Intel has gotten some of the thermal issues of the P4 Prescott out of the way on the new Extreme Edition processor which will come as good news to many.
In terms of overall performance, you aren't really looking at any great leaps in gaming environments over the original 1066FSB Gallatin Extreme Edition. Only when it comes to SSE3 enabled encoding programs we start to see the newest member of the EE family show its potential but the only real claim is 64-bit support.
With the release of Windows XP 64-bit to come sometime soon, Intel has assured itself that it won't be left out of the loop; Pentium 4 now has its hand in the 64-bit arena and it will now be left up to the software companies and game developers to make use of the PC technology which is now ready from both AMD and Intel.
