PCI-E X16 x4 bandwidth?
ya.. what about it?
What is the function of PCIe?
The PCI Express Root Port functions the same way as a regular PCI Express port, with the additional function of monitoring the interconnect hierarchy of the PCI ports. This function includes tracking the interconnect bandwidth and making sure that the PCI port hierarchy is functioning properly
What are the benefits of using PCI Express?
Not to be confused with PCI-X. A customer using PCI Express can enjoy the benefits of enhanced data processing to keep up with higher bandwidth rates. With higher speed serial interconnects the rate of data transfer is much higher versus previous PCI setups.
Who is faster a pci express x16 bus or the latest agp bus?
There is no latest AGP bus. The most recent bus designed for high performance equipment is PCI-E. And x16 has the highest bandwidth.
Will an 2.0 pci express video card work in a 1.0 pci express slot?
Yes it will but the video card will run at PCI express 1.0 speed.
Which motherboard offers both AGP and PCI slots for periphial cards?
That's a standard setup for older motherboards.However now PCI Express is becoming the preferred peripheral slot.The largest version of this has greater bandwidth than an AGP slot and has replaced it for high end graphics cards.Obviously PCI express is designed to be far superior to PCI.
Is a PCI express 16 bus or the latest AGP bus faster?
PCI x16 's bandwith far exceeds that of all other current expansion slots on home PC's. In other words make sure all your add-on cards are of this type if you motherboard can handle it. The Following table should give a good measurement of where we are at:Common Buses and their Max Bandwidth PCI 132 MB/s AGP 8X 2,100 MB/s PCI Express 1x 250 [500]* MB/s PCI Express 2x 500 [1000]* MB/s PCI Express 4x 1000 [2000]* MB/s PCI Express 8x 2000 [4000]* MB/s PCI Express 16x 4000 [8000]* MB/s PCI Express 32x 8000 [16000]* MB/s IDE (ATA100) 100 MB/s IDE (ATA133) 133 MB/s SATA 150 MB/s Gigabit Ethernet 125 MB/s IEEE1394B [Firewire] 100 MB/s* Note - Since PCI Express is a serial based technology, data can be sent over the bus in two directions at once. Normal PCI is Parallel, and as such all data goes in one direction around the loop. Each 1x lane in PCI Express can transmit in both directions at once. In the table the first number is the bandwidth in one direction and the second number is the combined bandwidth in both directions. Also please note that in PCI Express bandwidth is not shared the same way as in PCI, so there is less congestion on the bus.
Can a PCI-X card be plugged into a PCI slot not the other way around as I have only a PCI card slot?
Can it? Sometimes, in PCI 3.3V slots(PCI rev. 2.2 or newer).But should it? No, a PCI-X card should be not be inserted into PCI slot.Putting a faster card(e.g., PCI-X, 64-bit/133MHz) into a slower slot(PCI 2.2, 32-bit/33MHz) will force the card to transfer data much slower than what it is capable of doing.IOW, even if PCI-X cards sometimes work in PCI Revision 2.2 or newer slots it is pointless to do that since it defeats the purpose of having a PCI-X card, namely wider bandwidth. PCI-X(133MHz) cards are capable of approx 1.0GB/s transfers while PCI (32-bit/33MHz) can only handle approximately 0.1GB/s, theoretically. In reality both do somewhat less ... but putting a 1.0GB/s card into a 0.1GB/s slot is wasting perfectly good bandwidth(and the money spent to get it!).If you only have PCI(32-bit) slots, then buy only PCI(32-bit) cards.All PCI cards that adhere to PCI revision 2.2 or newer specifications can be used in PCI-X slots. ( Note that most cards are now manufactured to meet PCI 2.2 or 2.3 specifications. )However the transfer rate/speed will not necessarily increase because the card is in a slot capable of faster transfers.PCI slots that are older, prior to PCI rev. 2.2, should physically block the insertion of a normal PCI-X card into the slot.PCI cards that are older, prior to PCI rev. 2.2, should be physically blocked from being inserted into PCI-X slots.Both of the latter of course depend upon the manufacturer of the expansion card following the PCI specifications. Unfortunately not all manufacturers do that(so be careful!).As always there are various additions and exceptions but confusion is the general rule when they are considered so let's leave it as:Long card in short slot: no, it wastes bandwidth and money.Short card in long slot: ok, if it inserts without undo insertion force(but it also wates available bandwidth).
What is the difference between pci express 2.0 and pci?
PCI-E 2.0 ha s a higher bandwidth meaning more data can travel faster between the card in the slot and the motherboard/CPU. Im not sure of the exact numbers of data transfer speed but I'm sure the speed improvement is significant
What is PCI-X?
PCI Express is a bus for connecting peripherals to a motherboard internally. It is designed to provide higher performance / bandwidth than either PCI or AGP. Video cards, Ethernet cards, SCSI controllers, and sound cards are all available for this bus. PCI Express slots come in several different size, each designed to provide higher bandwidth. Cards designed for the smaller slots will work in the larger ones as well. PCI express is a expansion slot on your motherboard used to accomidate expansion cards ( sound video modems and other things) it Has a fast buss speed to run newer faster video cards for gameing and advanced video editing. It is a second generation to a standard PCI developed to replace and be more versitile than the current AGP (accelerated graphics port) but many new motherboards come with both AGP and multiple combos of PCI and PCI express slots.
What slot would you use for a network card?
I would generally use either a PCI or PCI Express slot for a modern computer. AGP network cards, while they do exist, are extremely rare and expensive. ISA is too slow and doesn't have enough bandwidth for modern networking needs.
What are the examples of expansion slot?
PCI, PCI-e, AGP
