PI7C8152A
ENHANCED 2-PORT PCI-to-PCI BRIDGE
INTEL 21152 COMPARISON
PERFORMANCE COMPARISON: PI7C8152A vs. INTEL 21152 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 S2460 Chipset: AMD 760DDR Processor: AMD Athlon 1.8GHz with 266MHz Front Side Bus Memory: 256MB PC2100 DDR Video: ATI Radeon 7000 AGP card Other PCI Devices: No other PCI devices active OS: Windows 2000
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
