Performance

As we have not yet benchmarked any i848P-based mainboard, we will start this review with the tests of the chipset memory subsystem in synthetic tests. The Cachemem test comes first:

 

ASUS P4PE
Intel 845PE

ASUS P4P800S
Intel 848P

ABIT IC7-MAX3
Intel 875P

ASUS P4P800
Intel 865PE

Memory read speed, MB/s

2739.6

2746.9

3679.3

3707.4

Memory write speed, MB/s

1034.9

1269.2

1592.4

1601.6

Memory copy speed, MB/s

1561.4

2921.8

2939.4

The results might have been predicted. The memory bandwidth of single-channel chipsets is lower than that of the dual-channel ones. As for the latency, it is similar in all the chipsets. Note also that the i848P was a little faster than the single-channel i845PE, which was tested with the FSB overclocked to 200MHz. I have already mentioned the reason for this superiority; it is HyperPath technology inherited by the ASUS P4P800S from the top-end models.

Now, let’s view the results of other synthetic benchmarks:

It’s again quite logical. The i848P is slightly ahead of the i845PE and is completely defeated by the chipsets with the dual-channel memory controller. However, these are only synthetic tests. We are more interested in the performance in real applications.

Things take a rather surprising turn, aren’t they? Still, that’s the fact: the good old single-channel i845PE chipset is best of all in Business Winstone 2002. The reason lies on the surface, though. This chipset provides the highest disk subsystem performance, which in its turn greatly contributes to the overall result in Business Winstone 2002. The old South Bridge (ICH4) of the i845PE is supported by an advanced caching driver, Intel Application Accelerator. Thanks to this driver, the i845PE has higher results in office applications.

Multimedia Content Creation Winstone 2003 brings no surprises. The results are exactly what they should be.

When encoding a video stream into the MPEG-4 format, the i848P-based ASUS P4P800S mainboard is only 1%behind the i875P- and i865PE-based mainboards.

Data compression is very much dependent on the memory subsystem bandwidth. Note also that the i848P is archiving information much better than the i845PE.
