Intel P4 800MHz FSB CPU Round-up - Overclocking Continued
(Page 6 of 7 )
(Overclocked Benchmarks continued...)
SiSoft Sandra Multimedia Benchmark
If there is going to be a bench to show the memory bandwidth gains of the higher DDR bus' made possible by the lower multipliers this one would be it. Is it?

Memory Bandwidth Results |
| | |
2.4c @ 3.522GHz | 2.6c @ 3.536GHz | 3.0GHz @ 3.561GHz |
I think this shows a pretty clear picture. Our 2.6c checking in with the highest memory bus easily leads the way with impressive scores in the 5600 range. Our 3.0G, though clocked higher on the CPU, is simply unable to hang with the other two checking in almost a full 500MB/s slower.
PiFast Benchmark:
I expect this to be interesting as well. I was personally anxious to see if the extra system bus speeds allowed for faster computations necessary in the PiFast Pi calculations.

While all CPU's turned in times close to one another, we see the higher memory throughput shining thru again with the 2.6c with the 2.4c next inline and out more expensive, higher clocked 3.0GHz lagging in the rear, but not by much.
PCMark 2002 System Benchmark
As PCMark2002 is designed supposedly to look at entire system performance it will be interesting at least to see the results of this synthetic benchmark and determine how much the higher system and memory bus speeds come into play.

Again we see the 3.0GHz, while clocked higher (but oh so slightly) bringing up the rear. The 2.6 remains ahead but only by the slimmest of margins over the 2.4c.
Comanche 4 Benchmark
If you recall the results from the default speed C4 comparison you'll remember that this is a very CPU dependant benchmark. I was anxious to see what the results of the overclocked chips, all roughly the same speed yet with different busses, would be. Again, we've run the benchmark at both 1024x768 and 1600x1200.


C4 apparently intends not to disappoint as the CPU dependency shines thru clearly again by turning in all buy identical scores across the board. While it clearly shows CPU scaling well, the place for C4 is growing small in Dev Hardware reviews.
Unreal Tournament 2003:
Just as with the default runs, we'll run both 640x480 and 1024x768.


So even with UT03 we are seeing very close to the same results. If we were forced to name a winner it would have to be the 2.6 followed by the 2.4, but that is close. The higher bus speeds appear to allow higher bursting in the frame rate department, but when it comes to the average rate you're left pretty much with a deadlock.
Alright, we're nearing the home stretch, let's knock out Aquamark and the 3dMark series then wrap this thing up eh?
