ndeupi musiyano uripo pakati peddr3 neddr4?

1. Madiro akasiyana

Iyo yekutanga frequency yeDDR3 ndangariro ingori 800MHz, uye iyo yakanyanya frequency inogona kusvika 2133MHz. Iyo yekutanga frequency yeDDR4 ndangariro ndeye 2133MHz, uye yakanyanya frequency inogona kusvika 3000MHz. Kuenzaniswa neDDR3 ndangariro, kuita kweyepamusoro frequency DDR4 memory inovandudzwa zvakanyanya mumativi ese. Pini yega yega yeDDR4 memory inogona kupa 2Gbps bandwidth, saka DDR4-3200 iri 51.2GB/s, iyo yakakwirira kupfuura iyo yeDDR3-1866. Bandwidth yakawedzera ne70%;

2. Chitarisiko chakasiyana

Seshanduro yakakwidziridzwa yeDDR3, DDR4 yakaita shanduko muchitarisiko. Zvigunwe zvegoridhe zveDDR4 memory zvave curved, zvinoreva kuti DDR4 haichaenderane neDDR3. Kana iwe uchida kutsiva DDR4 ndangariro, unofanirwa kutsiva iyo mamaboard nepuratifomu nyowani inotsigira DDR4 memory;

3. Kusiyana kwekuyeuka simba

Panyaya yekushanda kwendangariro, iyo yakakwira imwechete DDR3 huwandu inogona kusvika 64GB, asi chete 16GB uye 32GB inowanikwa pamusika. Hukuru hwehumwe huwandu hweDDR4 i128GB, uye huwandu hukuru hunoreva kuti DDR4 inogona kupa rutsigiro kune mamwe maapplication. Kutora DDR3-1600 ndangariro sereferensi bhenji, DDR4 ndangariro ine kuvandudzwa kwekuita kweinenge 147%, uye muganho wakakura kudaro unogona kuratidza mutsauko uri pachena;

4. Kushandiswa kwesimba kwakasiyana

Mumamiriro ezvinhu akajairwa, simba rekushanda reDDR3 ndangariro i1.5V, iyo inoshandisa simba rakawanda, uye iyo memory module inoenderana nekupisa uye kuderedza frequency, izvo zvinokanganisa mashandiro. Iyo yekushanda voltage yeDDR4 memory inonyanya 1.2V kana kunyange yakaderera. Kuderera kwekushandiswa kwesimba kunounza mashoma ekushandisa simba uye kushoma kupisa, izvo zvinovandudza kugadzikana kweiyo memory module, uye zvakanyanya hazvikonzeri kudonha kunokonzerwa nekupisa. frequency phenomenon;
