PI7C8148B 2-PORT PCI-to-PCI BRIDGE PCI6152 COMPARISON PERFORMANCE COMPARISON: PI7C8148B PCI6152
performance data measured using in-house evaluation board slotted into off-the-shelf motherboard. Fast Ethernet (100Mbit LAN) Cards reside each slots secondary evaluation board. each comparison, hardware software remain constant. only item changed bridge evaluation board. different sets hardware were used, description each fixture listed. each test setup, exerciser program used generate traffic write packets from Fast Ethernet card memory then read back from memory Fast Ethernet card. TEST CASE Motherboard: Chipset: Processor: Memory: Video: Other Devices:
