Kāds ir maksimālais ātrums, ka es varu lasīt un rakstīt datus uz PCI un ISA

 
PCI ir 33MHZ (66MHA) * 32 bit (vai 64 bitu), tad 128 kbyt / s līdz 528 kbytes / secconds .........

 
~8MB/sec, as I remember

ISA
~ 8MB/sec, kā es atceros:

PCI:

PCI32 33Mhz 32bit * 33Mhz ~ 133MB/sec (desktop variants)
PCI32 66Mhz 32bit * 66Mhz ~ 266MB/sec (servera)
PCI64 33Mhz 64bit * 33Mhz ~ 266MB/sec (servera)
PCI64 66Mhz 64bit * 66Mhz ~ 533MB/sec (servera)(also server bus):

PCI-X
(arī serveris autobusu):
64bit 133Mhz => 1066MB/sec
64bit 266Mhz (DDR) => 2.1GB/sec
64bit 533MHz (QDR) => 4.3GB/sec
(successor of PCI)

PCI-Express
(pārņēmēja PCI)

PCI Express Link - Joslas platums
x1 0.5GB/sec
x2 1.0GB/sec
x4 2.0GB/sec
x8 4.0GB/sec
x12 6.0GB/sec
x16 8.0GB/sec
x32 16.0GB/sec

piezīme: MB = megabaiti, GB = gigabaitiem
PS: arī tur ir daudz autobusi (piemēram, VLB, EISA, MCA), bet tie nav tik kopējo kā autobusi iepriekš
