PI7C8152A
ENHANCED 2-PORT PCI-to-PCI BRIDGE
INTEL 21152 COMPARISON
PERICOM SEMICONDUCTOR
Revision 1.1 – JUNE 2004
Page 2 of 3
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.
