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 930 system with an EVGA X58 Tri-SLI 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: This is the first time in ten motherboards that there was a dramatic difference in network performance. Nine of the ten boards that we have tested have had a network throughput of 942-945+Mbits/s. The ASUS Sabertooth X58 was only 752.336 Mbits/s. After a bit of trouble shooting to make sure my server wasn’t faltering I got in touch with ASUS and found out my results were spot on. This is what they had to say:
“It is due to the use of a PCI based network controller as opposed to a PCI-E based network controller. Your number is approximate to what we have from internal testing.
Due to the considerably higher quality components as well validation and other specific elements on the SABERTOOTH X58 this compromise was put into effect by the product manager. As most users realistically do not put heavy throughput loads on their network it was felt while not perfect it was practical implementation. In real world reality the performance offered of approximate 85 to 90MB is sufficient for even high performance data transfers including backups and HD streams.”
