Ethernet Performance

The K8VT890-9 uses Marvell's Yukon 88E8050 GigaE controller. This is a PCI-E controller, and is the same used on many high end motherboards, such as Intel's own flagship 925XE board. This will allow GigaE's true bandwidth potential to shine through.

The Soltek is using a PCI-based GigaE controller here, so you'll immediately notice the difference:

As you can see, GigaE controllers are capable of more bandwidth than the PCI bus can provide. Add to that the fact that the PCI bus is shared across all devices, and you can see why it is important to use PCI-E whenever possible.

Of course, because higher performance is provided, more CPU resources are used.

USB 2.0 Performance

To test USB2.0 performance, we connected an external USB 2.0 hard drive to the bus, and ran HDTach's Quick 8MB test. Average Read and Write speeds are given, as well as a CPU usage test, which has a margin of error of +/- 2%

Well the transfer rate is there, but look at the CPU usage. The VIA USB2.0 controller is definitely not optimized here.
