The Gigabit PCIe Ethernet controllers vary on each board, so it will be interesting to see what the performance is on all the boards. Each of the boards uses a different Gigabit Controller. Let’s take a look at what controller is on each of the boards.
To test the Gigabit PCIe Ethernet controllers we used the NTttcp tool to test Ethernet Throughput and the CPU utilization of the various Ethernet controllers used on the AMD Motherboards. To do this properly we set up one machine as the server: in this test an Intel Core I7 970 system with an MSI Big Bang XPower motherboard acted as our Gigabit LAN server.
On the server side, we used the following Command Line for Gigabit PCIe Ethernet Testing:
Ntttcpr -m 4,0,<Client IP> -a 4 -l 256000 -n 30000
On the client side (the motherboard being tested), we used the following Command Line:
Ntttcps -m 4,0,<Server IP> -a 4 -l 256000 -n 30000
At the conclusion of each test we recorded the throughput and CPU utilization figures from the client screen as that is the system being tested.
Benchmark Results: The GIGABYTE P67A-UD4 utilizes the same Ethernet controller as all of our boards except for the ASUS P8P67 Deluxe. Variances in network throughput for these four boards is nearly identical. Though we do see a difference in the CPU usage. The GIGABYTE P67A-UD4 uses less of the CPU than all of the boards using the Realtek 8111E Gigabit Ethernet controller. The only board that used less of the CPU is the ASUS P8P67 Deluxe which is utilizing the Intel 82579 Gigabit LAN Controller.
