VIA P4PB using Hyperion 4.46 drivers

 

Intel based boards using:
Intel Chipset Drivers, version 4.30.1006

Intel Application Accelerator, version 2.3

 

GeForce 4 Ti 4200-8x using:
NVIDIA Detonator Drivers, version 42.86


TESTING METHODOLOGY:

To help fully explain the scores we listed in the following benchmarks, we felt it was necessary to explain how the systems were setup before running the benchmarks. On all of the boards, we started off by manually optimizing the BIOS settings to the most aggressive system options available to us. The memory frequency was manually set to DDR333 with the CAS timings set to 2-5-5-2 and a 1T command rate except for the MSI 655 Max, which automatically detected the RAM as DDR400.  The hard drive was formatted, and Windows XP Professional with Service Pack 1 was installed. After the Windows installation was complete, we installed the necessary chipset drivers for each platform and Intel Application Accelerator on the Intel boards.  We then installed the drivers for the rest of the components, using the drivers supplied on the CD, except for the GeForce Ti 4200.  For the GeForce card, we downloaded and installed the latest NVIDIA reference drivers at the time of testing, version 42.86.

Auto-Updating, Hibernation, and System Restore were disabled, and then we set up a 768MB permanent page file. On these test systems we set the visual effects to "best performance" in system performance to limit any effects these settings would have on the benchmarks. With the newer 42.86 drivers, there are options to set the level of the drivers between "application" and "aggressive".  We set the video driver settings to "blend", balancing performance with quality.  Lastly, we installed all of the benchmarking software, defragged the machine, and rebooted one last time. 
 

Benchmarking with SiSoft Sandra 2003 Pro
Starting with the Synthetic...

SANDRA (the System ANalyzer, Diagnostic and Reporting Assistant) is an information and diagnostic utility put out by the folks at SiSoftware.  We have started using the 2003 version with has an updated database of components to compare.  It's a quick and easy way to compare the CPU, Memory, and Hard drive performance of a given system against an internal database of similar systems and drives. These benchmarks are theoretical scores, and can't necessarily be measured in real-world terms, but provide a good way to make comparisons amongst like components.  We ran a set of tests at the stock speed of 133MHz for the front side bus, and then again after achieving a stable overclock at 163MHz.
 

CPU Test
133MHz FSB

CPU Test
163MHz FSB

In the first picture, we see the Abit BH7 paired with the P4 2.53GHz CPU sitting pretty between the database scores for a P4 2.4GHz and a P4 2.66GHz.  (Side note: there were no scores in the database for a 2.53GHz P4).  In comparison to AMD Athlon XP chips, the Dhrystone score we got just topped the 2200+, but fell far off of the pace of the Athlon 2400+, which was the leader of the pack.  The P4s ruled the whetstones, where our score was only 170 MFLOPS behind the 2.66GHz P4.   As seen in the overclocked test on the right, we brought out the "big guns" for comparisons, including the top of the line P4 3.06 and Athlon XP 3000+.  The scores we achieved were very impressive, topping all other whetstone marks, and falling just shy of the Dhrystone scores for the top CPUs.   

 

Multimedia Test
133MHz FSB
Multimedia Test
163MHz FSB

In the Multimedia tests, the Integer Point calculations score was the second lowest of the CPUs rated, but was still a good showing for a P4 2.53.  The Floating Point score tipped the scales in the other direction.  We got the second highest score on the chart, just nipping on the P4 2.66GHz CPU's heels.  After we ran the test again at a FSB of 163MHz, we got results that beat out everything Sandra could throw at us.

 

Memory Test
133MHz FSB

Memory Test
163MHz FSB

For the memory test, we wanted to pick out chipsets that most closely resembled the boards we were testing when using DDR333.  As there was no P4X400 score when using PC2700 memory, we substituted a P4X333 instead.  As you can see, for the most part all of the boards using DDR333 produced similar scores, with the SIS648 taking a slight lead, the 845PE boards in the middle, and the VIA board last.  All three pale in comparison to the SIS 655, which uses a Dual DDR setup.  Dual DDR - Remember these words, because you will be hearing them more and more in the coming months. When we raised the front side bus up to 163MHz, we were effectively running the memory at 202MHz, a shade better than DDR400.  The score we got was better than the database score for an 845PE with PC3200 DDR, and weren't too far off of the Dual DDR scores from a Granite Bay (Intel 7205) or the SIS 655.
 

Hard Drive
Performance


The hard drive performance benchmark was just shy of the 30,000 mark, and much higher than a relative score for an ATA100 2MB cache hard drive.  It was right behind the ATA150 score, ostensibly from a Serial ATA drive.  The score was beat only by a drive with 8MB cache, such as a "Special Edition" Western Digital hard drive. 

Futuremark's benchmarks take the stage
