pali kusiyana kotani pakati pa ddr3 ndi ddr4?

1. Mafotokozedwe osiyanasiyana

Maulendo oyambira kukumbukira kwa DDR3 ndi 800MHz okha, ndipo ma frequency apamwamba amatha kufika 2133MHz.Maulendo oyambira kukumbukira kwa DDR4 ndi 2133MHz, ndipo ma frequency apamwamba amatha kufika 3000MHz.Poyerekeza ndi kukumbukira kwa DDR3, magwiridwe antchito amakumbukidwe apamwamba a DDR4 amakhala bwino m'mbali zonse.Pini iliyonse ya kukumbukira kwa DDR4 imatha kupereka 2Gbps bandwidth, kotero DDR4-3200 ndi 51.2GB/s, yomwe ndi yapamwamba kuposa ya DDR3-1866.Bandwidth idakwera ndi 70%;

2. Maonekedwe osiyana

Monga mtundu wokwezedwa wa DDR3, DDR4 yasintha mawonekedwe.Zala zagolide za kukumbukira kwa DDR4 zakhala zopindika, zomwe zikutanthauza kuti DDR4 sigwirizananso ndi DDR3.Ngati mukufuna kusintha kukumbukira kwa DDR4, muyenera kusintha bolodilo ndi nsanja yatsopano yomwe imathandizira kukumbukira kwa DDR4;

3. Kukhoza kukumbukira kosiyana

Pankhani ya kukumbukira kukumbukira, mphamvu imodzi yokha ya DDR3 imatha kufika 64GB, koma 16GB ndi 32GB zokha zomwe zimapezeka pamsika.Mphamvu imodzi yokha ya DDR4 ndi 128GB, ndipo mphamvu yokulirapo ikutanthauza kuti DDR4 ikhoza kupereka chithandizo pazinthu zambiri.Kutenga kukumbukira kwa DDR3-1600 ngati benchmark, kukumbukira kwa DDR4 kumakhala ndi kusintha kwa magwiridwe antchito osachepera 147%, ndipo malire akulu otere amatha kuwonetsa kusiyana koonekeratu;

4. Kugwiritsa ntchito mphamvu zosiyanasiyana

Nthawi zambiri, mphamvu yogwira ntchito ya kukumbukira kwa DDR3 ndi 1.5V, yomwe imagwiritsa ntchito mphamvu zambiri, ndipo gawo la kukumbukira limakonda kutentha ndi kuchepa kwafupipafupi, zomwe zimakhudza ntchito.Mphamvu yogwira ntchito ya kukumbukira kwa DDR4 nthawi zambiri imakhala 1.2V kapena kutsika.Kuchepa kwa mphamvu yogwiritsira ntchito mphamvu kumabweretsa kuchepa kwa mphamvu komanso kutentha pang'ono, zomwe zimapangitsa kuti pakhale kukhazikika kwa gawo la kukumbukira, ndipo kwenikweni sizimayambitsa kutsika chifukwa cha kutentha.pafupipafupi chodabwitsa;
