Iwill P4R533-N Motherboard
512MB of PC1066 RDRAM

ASUS P4T-E i850 Motherboard

512MB PC1066 RDRAM

 

 

Common Hardware:

Intel Pentium 4 2.4GHz

NVIDIA GeForce4 Ti 4600 (Drivers - v.28.32)

IBM 30GB ATA-100 7200RPM Hard Drive

Sound Blaster Live! Value

A Few Words About The Benchmarks:
In setting up our test machines, we install Windows XP on a formatted, FAT32 hard drive.  After installing the relevant drivers, we disabled system restore, all of the graphical enhancements in Windows XP, and the Automatic Update feature.  The desktop on each test bed is set to 1024x768, 16-bit color and a 75Hz refresh rate.

The Iwill board in this piece was setup with performance defaults enabled and the Asus board was set to performance defaults with the "RDRAM Turbo" option enabled.

 

We'll continue testing with a brief look at some synthetic benchmarks from SiSoftware's Sandra tests.

All of the Sandra numbers you see above are right where they should be for this type of setup.  In fact, the scores are right on top of the reference numbers provided by the Sandra software in these graphs.  Notice however, that the CPU clock is detected at slightly less than 2.4GHz.  Iwill chose to setup the board with modest and stable PLL timings, unlike what we have seen from manufacturers like Asus and Abit.  Specifically, the Asus board that we used for reference testing in this article, overclocks the CPU ever so slightly even at default speed, inching the PLL up a MHz or two in the process.  Please take this into account when viewing the remainder of the benchmarks. 

 

These Winstone scores, for all intents and purposes, are pretty much identical.  The Business Winstone side of things favored the slightly more robust timings of the Asus board.  We should also note that, although both boards were setup for PC1066 memory and 533 FSB at standard BIOS default settings, the Asus board has an "RDRAM Turbo Mode" function available in its BIOS.  As such, with it enabled, it does seem to edge past the Iwill P4R533-N.  Regardless, the differential is negligible.  

 

We've started to incorporate this benchmark into our tests for CPUs and motherboards, as well as graphics cards.  It is a great DX8.1 test but also is hugely CPU and system bandwidth dependant.  So it's a good indicator of overall performance as well.  Here the picture is pretty much the same, with both PC1066 configurations coming in neck and neck.  We've included a PC800 score on the Asus board, for reference.  Believe it or not, 3 fps in this test is fairly significant.

3DMark Scores that stress the CPU

In this test, we've set up MadOnion's 3DMark for Software Rendering for T&L.  This will place more of an emphasis on CPU performance, since the host processor is required to perform transform and lighting techniques algorithmically, in software, versus through our test system's GeForce4 card.

Here again we illustrate the performance edge PC1066 RDRAM speeds lend to the Pentium 4 versus PC800.  The added overall system bandwidth increases approximately 9%.  Also, once again the slightly more aggressive timings of the Asus board give it the edge versus the P4R533-N but the difference in minescule.
