DDR3 vs DDR4
Kab lus no nthuav tawm koj qhov kev sib piv ntawm DDR3 thiab DDR4, qhia txog qhov sib txawv tseem ceeb ntawm ob RAMs. Txawm li cas los xij, ua ntej delving rau hauv qhov sib txawv ntawm DDR3 thiab DDR4, cia peb pom qhov tshwj xeeb ntawm ob qho tib si RAMS. Raws li qhov tseeb, DDR, uas sawv cev rau Cov Ntaub Ntawv Thib Ob, yog qhov tshwj xeeb siv rau RAM. DDR4 yog qhov ua tiav ntawm DDR3 thiab yog li muaj kev txhim kho hauv cov khoom xws li kev siv hluav taws xob, qhov loj me, ceev thiab ua haujlwm tau zoo. DDR4, uas tau tso tawm xyoo no, tseem tsis tau muaj npe nrov hauv kev ua lag luam tab sis, nyob rau xyoo tom ntej, nws yuav sai sai no DDR3. DDR4 RAMs siv lub zog tsawg dua DDR3, tab sis lawv qhov ceev yog ntau dua. Tsis tas li ntawd, lub cim xeeb ceev tso cai yog siab dua hauv DDR4. Lub cev ntev ntawm DDR3 thiab DDR4 yog tib yam, tab sis lawv tsis rov qab sib haum raws li tus qauv sib txawv. Yog li ntawd, qhov thais hauv DDR3 thiab DDR4 nyob ntawm qhov chaw sib txawv thiab DDR4 module yuav tsis haum rau hauv lub qhov (socket) DDR3 thiab rov ua dua.
DDR3 yog dab tsi?
DDR3, uas sawv cev rau Cov Ntaub Ntawv Thib Ob Hom 3, yog hom Dynamic Random Access Memory (DRAM) uas tau los ua tus ua tiav ntawm DDR thiab DDR2. Nws tau tso tawm rau lub khw hauv xyoo 2007 thiab niaj hnub no yuav luag txhua lub khoos phis tawj thiab khoos phis tawj hauv khw siv DDR3 ua RAM. Qhov tshwj xeeb voltage rau DDR yog 1.5 V thiab, yog li ntawd, nws siv zog tsawg dua thaum piv rau nws cov thawj coj. DDR3 tus qauv tso cai chips mus txog 8 GB. DDR3 RAM muaj rau ntau zaus xws li 800, 1066, 1333, 1600, 1866, 2133 MHz. Lub DDR3 RAM module siv rau tus kheej lub computer muaj 240 tus pins thiab qhov ntev yog 133.35 hli. Lub DDR3 modules siv rau ntawm lub laptops hu ua SO-DIMM thiab nws qhov ntev me dua nrog qhov ntev ntawm 67.6 hli thiab tsawg tus pins uas yog 204 tus pins. Muaj ib qho tshwj xeeb ntawm DDR3 RAMs hu ua DDR3 tus qauv tsis tshua muaj hluav taws xob, uas tsuas yog siv 1.35 V es tsis yog 1.5 V thiab siv hauv qee lub xov tooj ntawm tes kom ua tiav lub roj teeb zoo dua.
DDR4 yog dab tsi?
DDR4 tau tshaj tawm xyoo no (2014) ua tus ua tiav rau DDR3. Tseem DDR4 tsis muaj npe nrov hauv kev ua lag luam vim nws nyuam qhuav tso tawm ob peb lub hlis dhau los thiab yog li cov niam ntawv hauv khw tseem txhawb nqa DDR3 nkaus xwb. Txawm li cas los xij, tom qab ob peb lub hlis, DDR4 yuav muaj tseeb dua DDR3. DDR4 stands rau Ob Chav Cov Ntaub Ntawv Tus Nqi Hom 4 thiab nws muaj ntau yam kev nce qib thiab kev txhim kho dua DDR3. DDR4 txhawb kev nco siab dua li 16 GB. Qhov zaus ntawm DDR4 modules muaj ntau dua li qhov DDR3 txhawb nqa thiab cov txiaj ntsig muaj yog 1600, 1866, 2133, 2400, 2667, 3200 MHz. Kev siv hluav taws xob ntxiv yog txo qis raws li qhov tshwj xeeb voltage yog 1.2 V. Qhov ntev ntawm DDR4 modules yog tib yam li qhov ntev ntawm DDR3 module, tab sis tus naj npawb ntawm cov pins tau nce. Cov qauv siv rau PCs muaj 288 tus pins thaum lub SO-DIMM modules siv rau lub laptops muaj 260 tus pins. Tus qauv qis voltage DDR4 RAM, uas yuav siv li ntawm 1.05 V, yuav muaj lub hom phiaj rau cov khoom siv txawb uas xav tau kev siv hluav taws xob zoo dua.
DDR3 thiab DDR4 yog dab tsi?
• DDR4 yog tus ua tiav ntawm DDR3.
• DDR3 tau qhia rov qab rau xyoo 2007 thaum DDR4 tau qhia hauv 2014.
• DDR3 txhawb nqa lub cim xeeb tsuas yog mus txog 8 GB, tab sis DDR4 txhawb kev nco ceev txog 16 GB.
• Qhov nrawm lossis zaus ntawm DDR4 RAMs ntau dua qhov zaus ntawm DDR3 modules. Qhov no ua rau DDR4 sai dua los ntawm kev muab tus nqi hloov pauv zoo dua.
• DDR3 ua haujlwm ntawm qhov hluav taws xob ntawm 1.5V thaum DDR4 ua haujlwm ntawm qhov hluav taws xob tsawg dua, uas yog 1.2V ua rau nws siv zog ntau dua.
• Muaj ib qho tshwj xeeb ntawm DDR3 thiab DDR4 hu ua tus qauv hluav taws xob tsawg, uas siv hluav taws xob tsawg dua li lub zog tsawg dua. Tus qauv qis voltage ntawm DDR3 siv 1.35V thaum nws yog 1.05V rau DDR4.
• DDR3 modules tsuas muaj 240 tus pins, tab sis DDR4 modules muaj 288 tus pins.

Summary:
DDR4 vs DDR3
DDR4 yog tus ua tiav ntawm DDR3 muaj ntau yam kev txhim kho. Qhov ceev lossis qhov zaus ntawm RAM modules tau nce ntau hauv DDR4 muab kev hloov pauv zoo dua. Ib qho DDR4 module tuaj yeem muaj qhov loj ntawm 16 GB thaum qhov no txwv rau 8 GB rau DDR3. Txawm li cas los xij, kev siv lub zog ntawm DDR4 tsawg dua nrog 1.2 V voltage siv tsis yog 1.5 V. Yog li ntawd, nws yuav muaj zog npaum li cas muab lub roj teeb zoo dua rau cov khoom siv txawb. DDR4 lub cim xeeb modules tsis sib xws nrog DDR3 slots thiab rov ua dua li no lub qhov ntawm lub motherboard txiav txim siab seb hom RAM yuav tsum tau kho. Tam sim no, cov tuam txhab lag luam siv DDR3 slots tab sis, nyob rau xyoo tom ntej, nws yuav hloov mus rau DDR4.
