With the launch of Intel’s P35 chipset, ASUS promptly released seven boards for you to choose from. A few weeks ago we had taken a look at the P5K3 and were left very impressed. Given the fact that the P5K is strikingly similar in specs, we hope to be left as equally impressed.
Nothing can prove the performance of a PC better than real-world benchmarks. The only downside to real-world tests is that it’s difficult to compare to a friends computer, unless they happen to have the same software and media files that you are encoding/converting. We can show direct differences though, since we run the exact same tests on each board.
To test video encoding capabilities, we ripped our “Lamb of God – Killadelphia” concert DVD and then used Nero Recode to convert it into something that can be burned on a normal sized DVD. The direct DVD rip is 7.7GB, and Recode compresses it into a 4.5GB frame.
Audio Decoding & Encoding
Similar to our video encoding test, we originally ripped a solid FLAC file from our “Tiesto – Elements of Life” album. From there, we decompressed it using flac -d and then compressed it into a 320Kbits MP3 using lame -b 320. FLAC 1.1.2 and LAME 3.97b2 were used for testing.
As mentioned earlier, I have performed numerous tests using 3DS Max 9 on multiple motherboards, to find that the end performance results hardly differed at all. My tests consisted of a 3200×2400 render, in addition to an export of 100 frames at 640×480. With both tests, the results were either exact or one second different.
Different motherboards use different chipsets for SATA controllers, so these tests are a good way to see how one board will compare to another. The first test is synthetic, using HD Tach RW/3, while the File Compression is real world, which involves compressing a 4GB folder (4,809 files) using 7-Zip.
The P5K performed quite well throughout all of our real-world tests. It fell a little short with our last test, however, being a full 40 seconds behind the XBX2, but staying well ahead of the 680i.
