Test Configurations

We have quite a round up of testbeds here, some dating back to the venerable Pentium4 "C" series and there is a very good reason to include some of these benchmarks, namely the fact that the new breed of processor is geared towards the community of upgrade users that are still chucking along happily with their maybe slightly dusty processors. A justified question of those users will be whether there is any incentive of upgrading from the existing hardware or not. Needless to say that the rest of the hardware plays an important role in some of the benchmarks and for that reason, we only show what we believe is a matching system configuration, likewise, we left out benchmarks that are too hard disk drive-limited and rather tried to customize all benchmarks shown such that the primary limiting factor is indeed the CPU.

One of our focal points was to look at what the increased cache size really does for performance, therefore, we are comparing directly the P4 560 to the P4 660 using an 18x multiplier in each case and a 200 MHz PSB. Likewise, we are running the same P4-560 at a 14x multiplier using a 1066 MHz host bus frequency for comparison with the new Extreme Edition. In terms of graphic representation of the results, there were different options, but we decided to use a color scheme based solely on the processor core, rather than on the packaging. That means, that e.g. all Prescott-1-based processors are colored in green, regardless of whether they are packaged in LGA 775 pr Socket 478 format. All Galatin core-based ExtremeEditions are red and the same limitations apply. Finally, the new Prescott 2 scores are given in blue and in this case there are no packaging options other than the LGA775. All other processors shown as supporting landmarks are using neutral shading to avoid distraction from the key points of this review.

Another quick clarification upfront: to distinguish between the P4 560 running at 3.6GHz and the same processor at 3.73GHz, we use the 925X moniker for the first and -925XE moniker for the latter. The X vs. XE may not be the most obvious distinction but it works for us and we'll add the respective information to the graphs wherever appropriate.
