yintoni umahluko phakathi kwe-ddr3 kunye ne-ddr4?

1. Iimpawu ezahlukeneyo

Ukuqala rhoqo kwememori ye-DDR3 yi-800MHz kuphela, kwaye i-frequency ephezulu inokufikelela kwi-2133MHz.Ukuqala rhoqo kwememori ye-DDR4 yi-2133MHz, kwaye i-frequency ephezulu inokufikelela kwi-3000MHz.Xa kuthelekiswa nememori ye-DDR3, ukusebenza kwememori ephezulu ye-DDR4 iphuculwe kakhulu kuzo zonke iinkalo.Iphini nganye yememori ye-DDR4 inokubonelela nge-bandwidth ye-2Gbps, ngoko i-DDR4-3200 yi-51.2GB / s, ephezulu kune-DDR3-1866.Ububanzi boluhlu bunyuke nge-70%;

2. Imbonakalo eyahlukileyo

Njengoguqulelo oluphuculweyo lwe-DDR3, i-DDR4 iye yatshintsha ngokubonakalayo.Iminwe yegolide yememori ye-DDR4 igobile, okuthetha ukuba i-DDR4 ayisahambelani ne-DDR3.Ukuba ufuna ukubuyisela imemori ye-DDR4, kufuneka utshintshe i-motherboard ngeqonga elitsha elixhasa imemori ye-DDR4;

3. Umthamo wenkumbulo owahlukileyo

Ngokubhekiselele ekusebenzeni kwememori, umthamo omnye we-DDR3 unokufikelela kwi-64GB, kodwa yi-16GB kunye ne-32GB kuphela ekhoyo kwimarike.Umthamo omnye ophezulu we-DDR4 yi-128GB, kwaye umthamo omkhulu uthetha ukuba i-DDR4 inokubonelela ngenkxaso yezicelo ezininzi.Ukuthatha imemori ye-DDR3-1600 njenge-benchmark yereferensi, imemori ye-DDR4 inokuphucula ukusebenza okungenani kwe-147%, kwaye umda omkhulu onjalo ungabonakalisa umahluko ocacileyo;

4. Ukusetyenziswa kwamandla ahlukeneyo

Kwiimeko eziqhelekileyo, i-voltage yokusebenza yememori ye-DDR3 yi-1.5V, edla amandla amaninzi, kwaye imodyuli yememori ilungele ukushisa kunye nokunciphisa ukuphindaphinda, okuchaphazela ukusebenza.Umbane osebenzayo wememori ye-DDR4 ubukhulu becala yi-1.2V okanye nangaphantsi.Ukuncipha kokusetyenziswa kwamandla kuzisa ukusetyenziswa kwamandla amancinci kunye nokushisa okuncinci, okuphucula ukuzinza kwemodyuli yememori, kwaye ngokusisiseko ayibangeli ukuhla okubangelwa ukushisa.ukwenzeka rhoqo;
