SiSoft Sandra Memory Bandwidth Benchmark:
Memory Bandwidth Results |
 |  |  |
P4 2.4c Default | P4 2.6c Default | P4 3.0GHz Default |
There are a few comments I wanted to make about these memory benchmark scores. One would think that because we are using the same memory at the same settings, and that all three CPU's are at 200MHz DDR bus that the scores should be identical. That is not the case and here is why. The faster the processor the faster the processing and the theoretical more bandwidth available, as can be seen above. This will come even more obviously into play once we get to the overclocking results, but I did want to make mention of it here.
PiFast Benchmark
This is a benchmark that is all but taylor made for CPU comparisons. It does pretty much exactly what it's title insinuates, it measures how fast your system calculates Pi. Taking into consideration that the CPU in your system carries out all calculations, this is a perfect tool to measure CPU performance. Keep in mind, the lower numbers are better, as we're measuring the TIME it takes to complete the calculations.
You'll notice that the gap between the CPU's is almost an exact percentage of the speed differences. That tells us the benchmark is working.
PCMark 2002 System Benchmark
PCMark2002 is Futuremark's (then MadOnion) complete system benchmarking tool. While these results and numbers in and of themselves don't necessarily mean anything, we've found that the results have scaled well in the past and felt it a good idea to include this in the CPU round-up.
Next up we've got some 3D benchmarks to see how each CPU performs in the type of applications that most of you are probably considering an upgrade to run!
Comanche 4 Benchmark
Comanche4 is in my opinion not a great benchmark for a video card review, but a stellar benchmark for a CPU review. This is because in the past we've found Comanche4 to be excessively CPU dependant. We're going to run this at both 1024x768 and 1600x1200. At 1024x768 using a Radeon9800 Pro it's safe to assume that the CPU will be the bottleneck giving us a crystal clear display of the CPU's performance differences. The 1600x1200 numbers are here to see if the price difference between these CPUs is justified for running ultra high resolutions during game play. Will the CPU dependant logic hold thru this time around? Lets find out.
The scaling difference between 1024x768 and 1600x1200 remain almost identical. All of the results are playable frame rates, but the extra horsepower of the 2.6c and 3.0GHz clearly shows..
Let's take a look at a few more benchs at default speeds and then crank it up in the huge overclocking section shall we? Click next and lets get on with it.
