PCI Qhia Txhais
PCI Express, technically Peripheral Component Interconnect Express , tiam sis feem ntau pom tau tias yog PCIe los yog PCI-E , yog ib hom kev sib txuas ntawm cov khoom siv hauv kev siv hauv tshuab computer.
Feem ntau, PCI nthuav qhia txog qhov tseeb qhov qhab nia ntawm lub niam ntawv uas lees txais cov ntawv teev lus PCIe raws li kev nthuav dav thiab cov hom ntawv nthuav dav lawv tus kheej.
PCI Express muaj tag nrho tiam sis hloov AGP thiab PCI, ob qho tib si uas tau hloov cov hom kev lag luam uas laus tshaj plaws hu ua ISA.
Thaum cov koos pis tawj muaj qhov sib xyaw ntawm ntau hom expansion slots, PCI Express yog xam tus qauv sab hauv. Muaj ntau lub computer motherboards hnub no yog tsim nrog PCI qhia qhov qhib.
PCI Express Ua Hauj Lwm Li Cas?
Zoo ib yam li cov laus xws li PCI thiab AGP, PCI Express raws li cov khoom siv (xws li hauv ib daim duab nyob rau ntawm nplooj ntawv no) ntawm lub cev zuj zus mus rau hauv PCI Express slot nyob rau hauv niam ntawv.
Lub PCI Express interface pub kom muaj kev sib txuas lus ntawm kev sib txuas ntawm cov cuab yeej thiab tus niam ntawv, thiab lwm yam khoom siv .
Txawm tias tsis tshua muaj tshwm sim, tus PCI qhia tawm sab nraud ntxiv, zoo li hu ua PCI Express sab nraud , tiam sis feem ntau luv luv rau ePCIe .
ePCIe cov khoom siv, ua rau sab nraud, yuav tsum muaj qhov tshwj xeeb txuas rau lwm tus, ePCIe ntaus ntawv siv rau hauv lub computer ntawm ib qho ePCIe chaw nres nkoj, feem ntau nyob rau sab nraum qab ntawm lub computer, los ntawm leej niam los yog ib daim npav PCIe tshwj xeeb.
Hom Kab Mob PCI Express Muaj Dab Tsi?
Ua tsaug rau qhov kev xav tau yooj yim thiab ntau dua qhov kev ua si yees duab thiab video editing cov cuab yeej, cov ntawv teev lus video yog thawj hom computer peripherals kom coj kom zoo dua cov kev txhim kho muaj los ntawm PCIe.
Thaum cov video phaib yooj yim tseem yog hom PCIe tshaj plaws koj yuav pom, lwm yam khoom siv uas tau txais txiaj ntsig los ntawm kev cuam tshuam cov kev sib txuas mus rau lub niam ntawv, CPU , thiab RAM yog tseem qhia ntxiv nrog PCIe cov kev sib txuas es tsis muaj PCI.
Piv txwv li, ntau lub suab nrov nrov kawg tam sim no siv PCI Express, raws li kev nce xov tooj ntawm kab sib txuas thiab kab sib txuas wireless network .
Daim npav tsav nyuab nyaj feem ntau yog qhov tseem ceeb tshaj plaws nrog PCIe tom qab video cards. Txuas nplua-ceev SSD tsav mus rau qhov siab bandwidth interface pub rau kev nyeem ntawv zoo dua los ntawm, thiab sau ntawv rau, tus tsav. Qee cov PCIe zog tsav ntxiag txawm muaj xws li SSD los ua, kev ruaj ntseg hloov ua li cas cia cov cuab yeej muaj kev sib txuas lus hauv computer.
Ntawm chav kawm nrog PCIe hloov PCI thiab AGP kiag li hauv newer motherboards, txhua yam ntawm sab hauv kev nthuav dav uas cia siab rau cov laus dua interfaces yog raug kho dua los txhawb PCI Express. Qhov no muaj xws li yam li USB expansion cards, Bluetooth cards, thiab lwm yam.
Cov Teeb Meem Sib Txawv PCI Yog Dab Tsi?
PCI Express x1 ... PCI Express 3.0 ... PCI Express x16 . Qhov 'x' txhais li cas? Koj yuav ua li cas qhia tau yog tias koj lub computer txhawb nqa qhov twg? Yog tias koj muaj daim npav PCI Express x1 tiam sis koj tsuas muaj PCI Express x16 chaw nres nkoj, puas ua haujlwm? Yog tsis yog, koj cov kev xaiv yog dab tsi?
Tsis nco qab? Txhob txhawj, koj tsis nyob ib leeg!
Nws feem ntau tsis yog txhua yam meej thaum koj mus yuav khoom rau ib daim ntawv nthuav tawm rau koj lub computer, xws li daim video tshiab, uas ntawm PCIe ntau yam ua haujlwm nrog koj lub computer los yog nws zoo dua li lwm qhov.
Txawm li cas los xij, nws ua txhua yam zoo nkaus li, nws tseem zoo nkauj yooj yim thaum koj nkag siab txog ob qho tseem ceeb ntawm cov ntaub ntawv hais txog PCIe: qhov piav qhia txog qhov loj me me, thiab qhov uas piav qhia txog technology tshuab, ob qho tib si tau piav qhia hauv qab no.
PCIe Qhov Siab: x16 vs x8 vs x4 vs x1
Raws li cov nqe lus pom zoo, tus naj npawb tom qab x qhia qhov loj me ntawm PCIe daim npav los sis qhov, x16 yog qhov loj tshaj plaws thiab x1 yog qhov tsawg tshaj plaws.
Ntawm no yog li cas qhov ntau thiab tsawg me me tuaj:
| Cov Pins | Ntev | |
| PCI Express x1 | 18 | 25 hli |
| PCI Qhia x 4 | 32 | 39 hli |
| PCI Qhia x8 | 49 | 56 hli |
| PCI Express x16 | 82 | 89 hli |
Txawm tias qhov teeb meem loj npaum li cas hauv PCIe qhov los yog daim npav, qhov tseem ceeb ntawm daim ntawv ceeb toom , qhov chaw me me hauv daim npav los sis qhov chaw, yog ib txwm nyob ntawm Pin 11 .
Hauv lwm lo lus, nws yog qhov ntev ntawm tus PIN 11 uas ua ntev ntev dua thaum koj tsiv tawm ntawm PCIe x1 rau PCIe x 16. Qhov no tso cai rau qee qhov yooj yim kom siv cov ntawv teev lus ntawm ib qho loj nrog qhov qhab nia ntawm lwm tus.
PCIe cards haum hauv txhua daim npav PCIe rau ntawm tus niam ntawv uas yog tsawg kawg li loj dua. Piv txwv, daim npav PCIe x1 yuav haum rau hauv PCIe x4, PCIe x8, los yog PCIe x16. Ib daim npav PCIe x8 yuav haum rau hauv txhua lub PCIe x8 lossis PCIe x16 qhov.
PCIe phaib loj dua qhov PCIe qhov kabmob yuav haum nyob rau hauv lub me me, tiam sis tsuas yog yog tias qhov PCIe qhov kev qhauj (piv txwv li tsis muaj lub tog tsho nyob rau ntawm qhov kawg ntawm lub qhov).
Feem ntau, ib daim npav loj PCI Express los yog qhov txhawb nqa txhawb zog siab dua, piv txwv tias yog ob daim npav los yog qhov qhab nia koj tau sib piv cov nyiaj yug tib PCIe version.
Koj tuaj yeem pom daim duab kos rau ntawm qhov website pinouts.ru.
PCIe Versions: 4.0 vs 3.0 vs 2.0 vs 1.0
Txhua tus xov tooj tom qab PCIe uas koj pom ntawm ib yam khoom los yog niam ntawv yog qhia txog qhov tseeb version nab npawb ntawm PCI Express specification uas txaus siab.
Ntawm no yog li cas ntau lub qauv ntawm PCI kev qhia sib piv:
| Bandwidth (ib txoj kab) | Bandwidth (ib txoj kab hauv x16 qhov) | |
| PCI Express 1.0 | 2 Gbit / s (250 MB / s) | 32 Gbit / s (4000 MB / s) |
| PCI Qhia 2.0 | 4 Gbit / s (500 MB / s) | 64 Gbit / s (8000 MB / s) |
| PCI Express 3.0 | 7.877 Gbit / s (984.625 MB / s) | 126.032 Gbit / s (15754 MB / s) |
| PCI Express 4.0 | 15.752 Gbit / s (1969 MB / s) | 252.032 Gbit / s (31504 MB / s) |
Tag nrho cov ntawv PCI nthuav tawm rov qab thiab nraim mus ntxiv, lub ntsiab lus txawm tsis muaj daim npav PCIe los yog koj qhov kev txhawb nqa niam txiv, lawv yuav tsum ua haujlwm ua ke, yam tsawg kawg kiag.
Raws li koj tuaj yeem pom, qhov loj tshiab rau PCIe tus qauv nce ntau qhov bandwidth muaj txhua lub sijhawm, zoo heev ua rau qhov kev sib txuas ntawm cov cuab yeej sib txuas ua ke.
Kev txhim kho cov qauv kuj kho cov yoov, ntxiv nta, thiab kev ua kom muaj zog tuaj, tab sis qhov nce hauv bandwidth yog qhov tseem ceeb tshaj plaws hloov los ntawm daim ntawv mus rau version.
Txhim kho PCIe Compatibility
PCI nthuav tawm, thaum koj nyeem hauv qhov ntau thiab tsawg dua cov tshooj saum toj no, txhawb kev zoo nkauj npaum twg txhua yam koj xav tau. Yog hais tias nws lub cev fits, nws zaum ua haujlwm ... uas yog qhov zoo.
Ib qho tseem ceeb tshaj plaws uas yuav tsum paub, txawm li cas los, yog tias kom tau nce cov bandwidth ntxiv (uas feem ntau yog qhov sib npaug ntawm qhov kev ua tau zoo tshaj plaws), koj yuav xav xaiv qhov PCIe version uas koj qhov kev txhawb zog siab thiab xaiv qhov loj tshaj PCIe loj uas haum.
Piv txwv li, PCIe 3.0 x16 daim video card yuav muab koj qhov kev ua tau zoo tshaj plaws, tab sis tsuas yog tias koj lub motherboard kuj txhawb PCIe 3.0 thiab muaj ib qho dawb PCIe x16 qhov. Yog tias koj lub motherboard tsuas yog txhawb nqa PCIe 2.0, daim npav tsuas yog ua haujlwm rau qhov kev txhawb zog siab (xws li 64 Gbit / s nyob rau hauv x16 qhov).
Feem coob ntawm cov niam txiv thiab cov computers tsim nyob rau hauv 2013 lossis tom qab ntawd tej zaum yuav txhawb nqa PCI Express v3.0. Ntsuam xyuas koj daim duab los yog lub tshuab computer yog tias koj tsis paub meej.
Yog tias koj nrhiav tsis tau cov ntaub ntawv tseem ceeb ntawm PCI version uas koj qhov kev txhawb nqa motherboard, Kuv xav kom yuav qhov loj tshaj plaws thiab qhov tseeb version PCIe, tsuav yog nws yuav haum, tau kawg.
Dab tsi yuav hloov PCIe?
Cov kev ua si video tsim yog ib txwm ntsia los tsim cov kev ua si uas tau muaj tseeb dua, tiam sis tsuas yog ua tau yog tias lawv tuaj yeem kis cov ntaub ntawv ntxiv los ntawm lawv cov kev pab cuam los ntawm VR lub computer los yog lub computer screen thiab kev sib tshuam kom sai dua rau qhov ntawd.
Vim li no, PCI Express yuav tsis kav mus kav lub tebchaws zoo tshaj plaws rau nws cov laurels. PCI Express 3.0 yog amazingly ceev, tab sis lub ntiaj teb xav tau sai.
PCI Express 5.0, vim yog ua tiav los ntawm 2019, yuav txhawb nqa ib tug bandwidth ntawm 31.504 GB / s ib kab (3938 MB / s), ob zaug qhov kev muab los ntawm PCIe 4.0. Muaj ntau ntawm cov txheej txheem tsis yog PCIe tus qauv tsim los ntawm kev lag luam technology, tiam sis txij li thaum lawv xav kom hloov kho kho mob loj, PCIe zoo rau tus thawj coj rau qee lub sijhawm tuaj.
