PERICOM SEMICONDUCTOR JUNE 2004 Page 2 of 3 PERFORMANCE COMPARISON: PI7C8140A vs. PLX PCI6140 The performance data was measured using an in-house evaluation board slotted into an off-the-shelf motherboard. Fast Ethernet (100Mbit LAN) Cards reside in each of the 4 PCI slots on the secondary bus of the evaluation board. In each comparison, the hardware and software remain constant. The only item changed is the bridge on the evaluation board. Two different sets of hardware were used, and the description of each fixture is listed. In each test setup, a PCI exerciser program is used to generate traffic or write packets from the PCI Fast Ethernet card to memory and then read back from memory to the PCI Fast Ethernet card. TEST CASE 1 Motherboard: Tyan S2721-533 v1.02 Chipset: Intel E7501 server Processor: Intel Xeon 2.4GHz Memory: 512MB DDR2100 Video: Onboard video Other PCI Devices: No other PCI devices active A Fast Ethernet card running full duplex is slotted in each of the 4 PCI slots on the evaluation board. Results: Transfer rate measured in Megabits per second Card Number Pericom PI7C8140A PLX PCI6140 LAN Card 1 35.81 – 38.45 Mb/s 10.96 – 12.16 Mb/s LAN Card 2 33.30 – 38.30 Mb/s 10.05 – 13.95 Mb/s LAN Card 3 18.10 – 20.70 Mb/s 3.50 – 5.40 Mb/s LAN Card 4 33.83 – 36.60 Mb/s 9.81 – 15.74 Mb/s TEST CASE 2 Motherboard: SuperMicro P3TDLE Chipset: ServerWorks ServerSet III LE Processor: Intel P III 800 Memory: 512MB Video: S3 TrioV64/DX Other PCI Devices: No other PCI devices active A Fast Ethernet card running full duplex is slotted in each of the 4 PCI slots on the evaluation board.
