Izinkambiso ziphi zokusebenza kwe-DDR4 kunge-DDR3 ukusiza kweserver?

Izindlela zokusebenza zezinhlelo zokuhlela zezinkundla zokusebenza zihlala ziyadinga ukusebenza kahle kwememory ukuze zihandle izisekelo sezinkundla eziningi futhi izidingo zokuprosesa idatha. Njengoba izimpahla zihlela izisekelo zabo futhi zibuyela emithombo yezintshukumo eziphelele, ukwahluka phakathi kwe-DDR4 memory neyodwa yalo eyodwa-3 kuyisahluko esibalulekile ekukhetheni imemory yokuhlela izinkundla. Ukuzwana ngamaphuzu amabili okunye nokwazi ukuthi i-DDR4 memory iyasebenza njani kungakhathalela kakhulu emaqengetweni akho okuhlela izinkundla futhi ekugcineni ukusebenza kwezinhlelo zokusebenza.

Ukuvutha Kwemiphumela Yokuqonda Kwesikhundla Se-DDR4 Memory

Ukuvutha Kwemiphumela Yokuqonda Ne-Width Yomkhondo

I-DDR4 yamemory iyathumela izikhathi zokuthumela idatha eziningi kunezikhathi zokuthumela i-DDR3, nesikhathi sezindawo esisodwa kusukela ku-2133 MHz ku-3200 MHz futhi phezulu kwalokho. Lokhu kucophelela kwezinkundla zokubhala eziningi, kuvumela amasheva ukuprosesa izinhlobo zedatha eziningi ngokufanayo. Izinkundla zokuphakama zokuthumela i-DDR4 zivumela amaprograme ukufinyelela kwezibhalo ezisodwa ngokushesha kakhulu, ukunciphisa isikhathi sokuzihlukanisa futhi ukuphutha ukuphindeleka kwesistimu yonke.

Server amaprograme ayiphrofitha kakhulu kulezinkundla zokubhala, ikakhulukazi emizimbeni yokusebenza kwezinhlobo zedatha, ukugcina kwezinhlobo zedatha, nokuchaza ngokushesha. Ukuphakama kwedatha kuvumela ukufinyelela kwezinhlobo zokubhala ngokulinganayo, kuvumela amaprocesa ukubhala ngokuphakama okuningi ngaphandle kokuhlala kusukela emiphakathini yamemory. Lokhu kubhekwa kakhulu emizimbeni eyisikhiwe kwezinhlobo zedatha apho izinhlobo zokubhala ze-DDR3 ziyakwakha izimpilo zokubhala.

Izinhlobo Zokubhala Eziningi Futhi Isikhathi Sokuzihlukanisa

Nakuba imemory ye-DDR4 iyasebenza kumakhonkotho amaningi, le teknoloji liyaphatha izibonelo zokugcina izikhathi zokufinyelela ngokuphelele. Imibhali yezibonelo zokugcina (prefetch buffers) nezindlela zokubeka izilungiselelo (command scheduling) eziyisivinini ziyabulawa ukuthi izicelo zememory zihlanganiswe ngokuvinini. Lezi zibonelo zokuguqula isithembiso ziyathinta ukuthi isistimu yonke ibe yinhle ngokwesiqondiso nakuba izikhathi zokufinyelela ziyinkulu kunezika DDR3.

Izifunda zokuphatha imemory ngokomlando kumemory ye-DDR4 zifaka isithembiso sokugcinwa kwemibhali yamaphuzu (bank group architecture), okuyisivinini ukuthi kuzofinyelelwa imemory ngokuhlanganisa. Lezi zindawo zokusebenza ngokuhlanganisa ziyavumela amasheva ukuthi abe ngezicelo zememory ngokuhlanganisa, okuyavumela ukuthi kwenziwe ngokuvinini izicelo eziningi, futhi kunciphiswe ukuthi kubhekana phakathi kwezicelo eziningi noma amashini evirtuali athi asebenza kusame isikhundla sesihlahla.

Ukusebenza Kwamandla Nokuphatha Intampu

Ukuncipha Kwamandla Okusebenzayo

Indlela eyinkulu yokuthuthukiswa kwe-DDR4 yokuqondisa kukhona ngokupheleleyo kwakho kubukhulu bekuphula kwamandla. Ngokusebenza ngama-volti angu-1.2 kungaphandle kwe-DDR3 engenayo ingcambu yama-volti angu-1.5, izikhundla ze-DDR4 zisemthwakisa amandla angu-20% ngaphansi futhi zinikeza ukusebenza okuhle kakhulu. Lokhu kucindezela ukuthuthukiswa kwamandla emisebenzi enkulu yezikhundla zezinhloko, apho izikhundla zezinhloko zingaphezu kwezihlanu noma zingaphezu kwezintathu zingahlanganisa kumandla okusebenza.

Ukuphula kwamandla kwe-DDR4 kusuka kwezinhloko zokuphula kwamandla kuphela, kuyadonsa ukuthuthukiswa kwesikhundla sokusebenza nokuphula kwamandla okusebenza. Amadatha senta ekusebenzisa izikhundla zezinhloko zingabona ukuphula kwezimali zokusebenza kwezimali zokusebenza ngokupheleleyo ngaphandle kokuthuthukiswa noma ukuthuthukiswa kwesikhundla sokusebenza. Umgama wokuphula kwamandla ukuhlanganisa kuzoba kubalulekile kakhulu njengoba izimpahla ziyagcina ukuthuthukiswa kwazo.

Izinkulungwane Zokuthuthukiswa Kwamandla

Ukuvutha kwezindawo zokusebenza kubhekisele ngqo ekuvutheni kwezindawo zokuhlanya kwezinkambo. I-DDR4 yamemory iyagwala amanzi amancane ngemuva kokusebenza, ukunciphisa umkhawulo wamandla wezinkambo zokuhlanya futhi ukuvutha kwezindawo zokusebenza zonke. Amakhanda amancane okusebenza ayakusiza ekuphindeleleni kwamaphakathi kanye nokunciphisa isivumelwano sokugwala amanzi ngokukodwa kwezinkambo zokusebenza zezindawo zokusebenza ezinconywa kakhulu.
