PCI Express, technically Peripheral Component Interconnect Express tab sis feem ntau pom luv luv li PCIe lossis PCI-E, yog tus qauv sib txuas rau cov khoom siv sab hauv hauv lub computer.
Feem ntau, PCI Express hais txog qhov tseeb nthuav dav ntawm cov niam ntawv uas lees txais PCIe-raws li nthuav daim npav thiab hom ntawv nthuav dav lawv tus kheej.
PCI Express tag nrho tab sis tau hloov AGP thiab PCI, ob qho tib si hloov pauv qhov qub tshaj plaws siv kev sib txuas hom hu ua ISA.
Thaum lub khoos phis tawj tuaj yeem muaj ntau hom kev nthuav dav, PCI Express suav tias yog tus qauv sab hauv interface. Ntau lub computer motherboards niaj hnub no tsuas yog tsim nrog PCIe slots.
PCI Qhia Ua Haujlwm Li Cas?
Zoo li cov qauv qub xws li PCI thiab AGP, PCI Express-based ntaus ntawv (zoo li ib qho pom hauv daim duab ntawm nplooj ntawv no) lub cev swb mus rau hauv PCI Express qhov ntawm lub motherboard.
PCI Express interface tso cai rau kev sib txuas lus bandwidth siab ntawm cov cuab yeej thiab cov niam ntawv, thiab lwm yam khoom siv.
Thaum tsis muaj ntau, muaj ib qho txawv ntawm PCI Express tshwm sim, tsis xav tsis thoob hu ua External PCI Express tab sis feem ntau luv rau ePCIe.
ePCIe cov khoom siv, yog sab nraud, xav tau ib lub xov tooj tshwj xeeb los txuas cov khoom siv sab nraud ePCIe rau lub khoos phis tawj ntawm qhov chaw nres nkoj ePCIe, feem ntau nyob rau sab nraub qaum ntawm lub khoos phis tawj, muab los ntawm motherboard lossis daim npav tshwj xeeb hauv PCIe.
Hom PCI Express Card muaj dab tsi?
Ua tsaug rau qhov kev thov kom nrawm dua thiab muaj tseeb dua video games thiab cov cuab yeej kho video, video phaib yog thawj hom computer peripherals coj kom zoo dua ntawm kev txhim kho los ntawm PCIe.
Thaum daim npav video yooj yim tseem yog hom PCIe daim npav feem ntau koj yuav pom, lwm yam khoom siv uas tau txais txiaj ntsig los ntawm kev sib txuas nrawm dua rau cov niam ntawv, CPU, thiab RAM kuj tseem tsim khoom nrog PCIe kev sib txuas tsis yog PCI sawv daws..
Piv txwv li, ntau daim npav suab nrov tam sim no siv PCI Express, raws li kev nce tus lej ntawm ob lub xov tooj thiab wireless network interface phaib.
Hard drive controller cards tej zaum yuav tau txais txiaj ntsig zoo tshaj plaws los ntawm PCIe tom qab daim npav video. Txuas lub PCIe ceev ceev, zoo li SSD, rau qhov kev sib txuas siab bandwidth no tso cai rau kev nyeem ntawv sai dua los ntawm, thiab sau ntawv mus rau, tsav. Qee qhov PCIe hard drive controllers txawm suav nrog SSD built-in, hloov pauv hloov pauv li cas cov khoom siv sib txuas hauv lub computer.
Tau kawg, nrog PCIe hloov PCI thiab AGP tag nrho hauv cov motherboards tshiab, tsuas yog hais txog txhua hom kev nthuav dav hauv daim npav uas tso siab rau cov laus interfaces tau raug kho dua tshiab los txhawb PCI Express. Qhov hloov tshiab suav nrog tej yam xws li USB expansion phaib, Bluetooth phaib, thiab lwm yam.
Dab tsi yog qhov txawv PCI Express Formats?
PCI Express x1 … PCI Express 3.0 … PCI Express x16. Qhov 'x' txhais li cas? Koj qhia li cas yog tias koj lub computer txhawb qhov twg? Yog tias koj muaj PCI Express x1 daim npav, tab sis koj tsuas muaj PCI Express x16 chaw nres nkoj, puas ua haujlwm? Yog tsis yog, koj xaiv dab tsi?
tsis meej pem? Tsis txhob txhawj; koj tsis nyob ib leeg!
Nws feem ntau tsis meej meej thaum koj mus yuav daim npav nthuav dav rau koj lub khoos phis tawj, zoo li daim npav video tshiab, uas ntawm ntau yam PCIe thev naus laus zis ua haujlwm nrog koj lub computer lossis qhov zoo dua li lwm qhov.
Txawm li cas los xij, raws li qhov nyuaj raws li txhua yam zoo li, nws yooj yim zoo nkauj thaum koj nkag siab ob daim ntaub ntawv tseem ceeb ntawm PCIe: ntu uas piav qhia lub cev qhov loj me thiab ib qho uas piav qhia txog cov qauv thev naus laus zis, ob qho tib si piav qhia hauv qab no.
PCIe Qhov Loj: x16 vs x8 vs x4 vs x1
Raws li cov lus qhia, tus lej tom qab x qhia lub cev loj ntawm PCIe daim npav lossis qhov, nrog x16 yog qhov loj tshaj plaws thiab x1 yog qhov tsawg tshaj plaws.
Ntawm no yog qhov ntau thiab tsawg zoo li:
| PCI nthuav qhia qhov sib piv cov lus | ||
|---|---|---|
| dav | ||
| PCI Express x1 | 18 | 25 mm |
| PCI Express x4 | 32 | 39 mm |
| PCI Express x8 | 49 | 56 mm |
| PCI Express x16 | 82 | 89 mm |
Txawm hais tias qhov loj ntawm PCIe qhov lossis daim npav, qhov tseem ceeb notch, qhov chaw me me hauv daim npav lossis qhov, yog ib txwm nyob ntawm Pin 11. Hauv lwm lo lus, nws yog qhov ntev ntawm Pin 11 uas tau ntev dua thaum koj txav ntawm PCIe x1 mus rau PCIe x16. Nws tso cai rau qee qhov yooj yim siv daim npav ntawm ib qhov loj me nrog cov qhov ntawm lwm qhov.
PCIe phaib haum rau txhua qhov PCIe ntawm lub motherboard uas tsawg kawg yog loj npaum li nws yog. Piv txwv li, daim npav PCIe x1 yuav haum rau txhua qhov PCIe x4, PCIe x8, lossis PCIe x16 qhov. Ib daim npav PCIe x8 yuav haum rau txhua qhov PCIe x8 lossis PCIe x16 qhov.
PCIe phaib loj dua PCIe qhov yuav haum rau hauv qhov me me tab sis tsuas yog tias nws qhib-kawg (piv txwv li, nws tsis muaj qhov nres thaum kawg).
Feem ntau, daim npav PCI Express lossis qhov loj dua txhawb nqa kev ua tau zoo dua, piv txwv li ob daim npav lossis qhov koj tab tom sib piv kev txhawb nqa tib lub PCIe version.
Koj tuaj yeem pom daim duab pinout tiav ntawm lub vev xaib pinouts.ru.
PCIe Versions: 4.0 vs 3.0 vs 2.0 vs 1.0
Txhua tus lej tom qab PCIe uas koj pom ntawm cov khoom lossis motherboard qhia tus lej version tshiab ntawm PCI Express specification uas tau txhawb nqa.
Ntawm no yog li cas ntau yam ntawm PCI Express piv:
| PCI Express Link Performance Comparison Table | ||
|---|---|---|
| Bandwidth (ib txoj kab) | Bandwidth (ib txoj kab hauv ib qho x16 qhov) | |
| PCI Express 1.0 | 2 Gbit/s (250 MB/s) | 32 Gbit/s (4000 MB/s) |
| PCI Express 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) |
Txhua PCI Express versions rov qab thiab xa mus tau zoo, txhais tau tias txawm tias daim npav PCIe lossis koj lub motherboard txhawb nqa, lawv yuav tsum ua haujlwm ua ke, yam tsawg kawg ntawm qib qis.
Raws li koj tuaj yeem pom, qhov hloov tshiab loj rau PCIe tus qauv tau nce qib bandwidth muaj nyob rau txhua lub sijhawm, ua rau muaj peev xwm ua rau cov khoom siv txuas nrog tuaj yeem ua tau.
Version txhim kho kuj tau kho cov kab mob, ntxiv cov yam ntxwv, thiab txhim kho kev tswj hwm lub zog, tab sis qhov nce hauv bandwidth yog qhov hloov pauv tseem ceeb tshaj plaws los ntawm kev hloov mus rau version.
Maximizing PCIe Compatibility
Raws li koj tau nyeem hauv qhov ntau thiab tsawg thiab cov qauv saum toj no, PCI Express txhawb nqa zoo nkauj npaum li cas txhua qhov kev teeb tsa koj tuaj yeem xav txog. Yog tias nws lub cev haum, nws yuav ua haujlwm, uas yog qhov zoo heev.
Txawm li cas los xij, ib qho tseem ceeb uas yuav tsum paub yog kom tau txais qhov nce bandwidth (uas feem ntau sib npaug rau qhov kev ua tau zoo tshaj plaws), koj yuav xav xaiv qhov siab tshaj PCIe version uas koj lub motherboard txhawb nqa thiab xaiv qhov loj tshaj PCIe loj uas yuav haum.
Piv txwv li, PCIe 3.0 x16 video card yuav muab qhov kev ua tau zoo tshaj plaws rau koj, tab sis tsuas yog tias koj lub motherboard kuj txhawb PCIe 3.0 thiab muaj qhov dawb PCIe x16. Yog tias koj lub motherboard tsuas yog txhawb nqa PCIe 2.0, daim npav tsuas yog ua haujlwm mus txog qhov kev txhawb nqa ntawd (piv txwv li, 64 Gbit / s hauv x16 qhov).
Feem ntau cov niam ntawv thiab cov khoos phis tawj tsim tawm xyoo 2013 lossis tom qab ntawd tej zaum yuav txhawb nqa PCI Express v3.0. Xyuas koj lub motherboard lossis computer phau ntawv yog tias koj tsis paub meej.
Yog tias koj tsis tuaj yeem pom cov ntaub ntawv tseem ceeb ntawm PCI version uas koj lub motherboard txhawb nqa, peb xav kom yuav daim npav loj tshaj plaws thiab tshiab kawg ntawm PCIe, tsuav nws yuav haum, tau kawg.
Dab tsi Yuav Hloov PCIe?
Video game developers yeej ib txwm nrhiav los tsim ib tug tiag tiag kev ua si. Lawv tsuas tuaj yeem ua qhov ntawd yog tias lawv tuaj yeem dhau cov ntaub ntawv ntau ntxiv los ntawm lawv cov kev ua si hauv koj lub VR lub mloog pob ntseg lossis lub vijtsam computer; Yuav tsum muaj kev cuam tshuam sai dua rau qhov tshwm sim.
Vim qhov no, PCI Express yuav tsis txuas ntxiv ua tus kav, so ntawm nws cov laurels. PCI Express 3.0 yog qhov nrawm nrawm, tab sis lub ntiaj teb xav tau sai dua.
PCI Express 5.0, pom zoo thiab tso tawm xyoo 2019, txhawb nqa qhov bandwidth ntawm 31.504 GB / s ib txoj kab (3938 MB / s), ob zaug qhov uas tau muab los ntawm PCIe 4.0.
Kev lag luam thev naus laus zis muaj ntau lwm cov qauv tsis yog PCIe interface, tab sis txij li lawv yuav xav tau kev hloov kho kho vajtse tseem ceeb, PCIe zoo li ua tus thawj coj rau qee lub sijhawm tom ntej.
