Lub koom haum PCI-SIG lub luag haujlwm rau kev txhim kho ntawm PCI Express specifications tshaj tawm qhov kev saws me nyuam ntawm cov kev qhia tshwj xeeb hauv qhov kawg version ntawm version 5.0. Kev txhim kho ntawm PCIe 5.0 yog cov ntaub ntawv rau kev lag luam. Cov kev qhia tshwj xeeb tau tsim thiab pom zoo hauv 18 lub hlis xwb. PCIe 4.0 specifications tau tawm . Peb tam sim no yuav luag rau lub caij ntuj sov xyoo 2019, thiab qhov kawg ntawm PCIe 5.0 tuaj yeem rub tawm los ntawm lub koom haum lub vev xaib (rau cov tswv cuab sau npe). Rau ib txwm bureaucratic system, qhov no yog ib qho txuj ci tseem ceeb ntawm acceleration. Vim li cas thiaj muaj kev maj nrawm?
PCIe 4.0 version specifications siv 7 xyoo los tsim thiab txais yuav. Thaum lub sijhawm lawv tau txais kev pom zoo, lawv tsis tau ntsib cov teeb meem tshiab: kev kawm tshuab, AI thiab lwm yam kev ua haujlwm hnyav thaum lub sijhawm sib pauv cov ntaub ntawv ntawm cov txheej txheem, cov khoom siv subsystems thiab cov accelerators, suav nrog daim npav video. Qhov tseem ceeb PCI Express acceleration yuav tsum tau ua kom txaus siab txhawb nqa cov haujlwm tshiab. Hauv version 5.0, qhov sib pauv ceev tau rov ua dua ob npaug piv rau cov qauv dhau los: los ntawm 16 gigatransactions ib ob mus rau 32 gigatransactions ib ob (nyob rau hauv cov nqe lus ntawm 8 kab).
Kev hloov ceev ntawm ib kab yog li tam sim no txog 4 GB / s. Rau cov classic configuration ntawm 16 kab, saws rau video card interfaces, qhov ceev pib mus txog 64 GB / s. Vim hais tias PCI Express ua haujlwm nyob rau hauv tag nrho duplex hom, tso cai rau ib txhij hloov cov ntaub ntawv nyob rau hauv ob qho tib si qhia, tag nrho bandwidth ntawm PCIe x16 tsheb npav yuav ncav cuag 128 GB / s.
PCIe 5.0 specifications muab rov qab sib raug zoo nrog cov khoom siv ntawm cov tiam dhau los, mus txog version 1.0. Txawm li cas los xij, qhov txuas txuas txuas tau raug txhim kho, txawm tias nws tsis tau poob rov qab sib raug zoo. Cov neeg kho tshuab lub zog ntawm cov khoom txuas tau raug txhim kho, raws li muaj qee qhov kev hloov pauv rau lub teeb liab qauv ntawm lub interface kom ntseeg tau tias cov teeb liab kev ncaj ncees (txo qhov cuam tshuam ntawm crosstalk).
Cov khoom siv nrog lub npav PCIe 5.0 yuav tsis tshwm sim hauv khw hnub no lossis tam sim no. Hauv Intel server processors, , PCIe 5.0 kev txhawb nqa yuav tsum nyob rau hauv 2021. Txawm li cas los xij, tus qauv tshiab yuav tsis tsuas yog nkag mus rau hauv kev ua haujlwm siab ntawm kev suav. Nyob rau tib lub sijhawm, nws tseem yuav suav nrog hauv tus kheej lub computer.
