VIA VPSD P4PB 400 - Page 7

..:: SiSoft SANDRA ::..

Well, weíll start off todayís tests with SiSoftís SANDRA benchmarking utility. In the Arithmetic tests, the P4PB 400 falls just shy of the 845 Ultra-AR in Floating Point performance; however it does overtake the P4PA ever so slightly. The P4PB 400 emerges as the leader of the pack in the ALU performance powering ahead of the 845 Ultra-AR. In the multimedia test, we see similar results with the P4PB 400 falling just short of the 845 Ultra-AR in FPU performance, but taking the overall lead again in ALU performance. This time however, the margin is not as large as in the arithmetic tests. In the hard drive benchmark, we see the P4PB 400 taking a fair lead over the competition, with the P4PA coming in second, and the 845 Ultra-AR bringing up the rear. Lastly we have the memory benchmark which is a no contest victory for the P4PB 400 as it is our only board utilizing DDR333 memory. The P4PB 400 does put up some very nice numbers when itís running at full capability.

..:: SuperPI ::..

In the SuperPI tests, we run the program three times, once at 512,000, once at one million, and once at two million. The numbers in the graph above show the time in seconds that it took the system to calculate pi to the set number of digits. In this benchmark, we can clearly see the processing superiority of the P4PB 400 over both the P4PA and 845 Ultra-AR. It pulls ahead in the two million digit computation by 10 seconds over the P4PA, and 13 seconds over the 845 Ultra-AR!

..:: SPECviewperf 6.1.2 ::..

Things are close, and distant at several times throughout the SPECviewperf 6.1.2 test. I was a little disappointed however when the P4PB 400 fell behind both the P4PA and 845 Ultra-AR in the ProCDRS, and Awadvs_04 test. With the utilization of a faster memory bus, the P4PB should top out on each test; however we can see that that is not the case. For the remaining tests in SPECviewperf 6.1.2, the P4PB 400 comes home the winner. In the Light_04 test, the board manages to break the 11.00 mark, a first in our testing labs. The P4PB 400 does show some superiority in the MedMCAD test, pulling ahead of both boards by 13 frames per second, and in the DX_06 test where it again manages to pull ahead, this time by a little over 8 frames per second.

..:: Cinebench 2000 ::..

The Cinebench 2000 tests show the boards coming in nearly equal in all tests. In Cinebench, a small margin can mean a good deal of performance difference in the end due to the fact it is indeed a very stressful test upon the system overall. Here, we see the P4PB 400 coming in as the leader in all benchmarks, sometimes by a minimal amount, and other times by a larger amount. The P4PB 400 really shows its strength when tested against itís younger, P4X266A powered sibling, the P4PA. Several times the 845 Ultra-AR comes close, but does not overtake the P4PB 400.

..:: MadOnion 3DMark2001 SE ::..

MadOnionís 3DMark2001 SE shows our P4PB 400 turning in some good numbers and coming out on top, especially in the lower resolutions. However, when we reach a resolution of 1280 x 1024, we see that the P4PB 400 falls back to second place behind the 845 Ultra-AR. In all other lower resolution tests, we see that the DDR333 powered P4PB 400 is superior, but when it come to the hard-hitting high resolutions, even having a faster memory subsystem doesnít always mean that the motherboard will come in as the winner. Overall, we see the P4PB 400 holding around a 3-5% lead over the competition up until the higher resolutions.

..:: Quake III Arena ::..

Our last test, Quake III Arena Demo 001 shows our P4PB 400 laying a big beating on the competition in the 800 x 600 resolutions. Here we see that the P4PB 400 scores in with 296.9 frames per second in 16-bit mode, and 287.8 frames per second in 32-bit mode. Overall, we are seeing a 19%, and 17% jump in frame rate from the P4X266A powered P4PA to the P4PB 400. When we kick up the resolution a bit, we see that the P4PB is once again capable of taking home the crown by an average of 8%. When we get up to the higher resolutions, the bandwidth bottleneck kicks in, however the P4PB 400 is still able to keep itís lead, unlike what we experienced in our testing with MadOnionís 3DMark2001 SE.

Overall, the P4PB 400 holds a commanding lead as far as our benchmarks go. It maintains a sizeable lead over the competition in nearly all tests as it should, however at times it does fall behind. I was a slight bit disappointed when the P4PB 400 didnít come out on top in all tests, much do to itís use of faster DDR333 memory, however when we see performance differences like we saw with Quake III, it more than makes up for it. Well, weíve seen the board, the features, the BIOS, and the benchmarks, now itís time to wrap it all up into a nice conclusion and call it a day.
