56 Chapter 6: Matrox Pulsar hardware reference Data transfer rate Although the PCI’s maximum data transfer rate is 132 Mbytes/sec, actual performance is generally much less; it depends on CPU memory caching, interactions between boards, and the quality of the system’s PCI bus interface. Some PCI bus systems, for example, those with an Intel 430NX (Neptune) chipset, do not offer sufficient bandwidth for full transfer capability with Matrox Pulsar. PCI bus systems using a newer PCI chipset, such as the Intel 430HX, 430VX, 430TX, 440FX, or 440LX, offer sufficient bandwidth to ensure full transfer capability to system memory with Matrox Pulsar. In such cases, Matrox Pulsar can achieve the following data rates: Initiator (Master) Host memory Matrox Pulsar Access Type Location write write Performance frame buffer 50 Mbytes/sec Host memory 60 Mbytes/sec
