GM-VT6202A-2C USB 2.0 Controller

This adapter is based on VIA VT6202 chip. There are two external USB 2.0 ports laid out on it. It supports PCI interface. I do not know who is the manufacturer of the card, I assume that it is most likely to be one of the Chinese or Taiwanese companies. The controller is shipped with a driver CD-disk.

Intel 865PE

Intel 865PE chipset features ICH5 South Bridge, which is going to be the topic of our today’s discussion, because it is exactly the one responsible for the implementation of high-speed USB 2.0 bus.

Of course, we cannot test the South Bridge as is, that is why we took a mainboard based on the above mentioned chipset and tested it.

Testbed and Methods

In order to test the controllers performance and to estimate which of them is the fastest, we used the following software:

  • FC-Test version 0.5.3;
  • WinBench99 2.0
  • IOMark version 0.30b14;
  • Intel IOMeter version 2003.02.15;
  • HD Tach version 2.61.

As a testbed for our session we used the following system:

  • Albatron PX865PE Pro mainboard;
  • Intel Pentium 4 2.4GHz CPU;
  • IBM DTLA-307015 15GB HDD;
  • Radeon 7000 32MB graphics card;
  • 256MB RAM;
  • Microsoft Windows 2000 with Service Pack 4.

We used the following drivers for the controllers:

  • Intel ICH5, 5.0.1006.0 on 15.01.2003;
  • NEC 7200100AGM, 5.0.2195.6177 on 19.06.2003;
  • VIA VT6202, 5.12600.1 on 15.2.2003.

In order to evaluate the efficiency of the USB 2.0 controllers installed into the mainboard PCI slot and those integrated into the chipset South Bridge, we used an external StorageKingdom EasyHardDisk USB 2.0 20GB and Western Digital WD2500JB HDD installed into Gembird Flexi Drive 2.0 portable chassis.
