Li-DRAM ye-DDR4 ne-DDR5 liyadinga izindlela ezihlukene zokuvunikula kwe-virtualization?

Yebo, i-DRAM ye-DDR5 iyasebenza kahle ngezindlela zokuvunikula ezihlukene, ikakhulu ngokugcinwa kwe-NUMA topology nezindlela zokugcinwa kwe-memory affinity. Iziphakade zokusebenza kwe-DDR5 ziyagcinwa kahle kwe-NUMA, njengoba izindlela zokufunda imemory phakathi kwezisokisi ziyabonakala kahle. Ngaphezu kwalokho, ukusebenza kahle kwe-DDR5 kusiza ukusebenza kahle kwezindlela zokugcina imemory ngokuphakeme kwezinkambo zokusebenza ngaphandle kokuthi kubhekwe ukuthi kusebenza kahle.

Izinkinga zokusebenza nokuhlisa kwezindawo zokugcina izinhliziyo zikuphi kusukela ku-DDR4 ku-DDR5 emaphakathi amanquma okugcina izinhliziyo?

I-DDR5 yasebenza ngemvume yama-1.1V kuloko kwe-DDR4 eyasebenza ngemvume yama-1.2V, ekhombisa ukuthi kunezinkambo zezibhalo eziningi ngokwesibili (20%) zokusebenza kubiti ngalinye eshukumiswe. Emaphakathi amanquma apho izisebenzi zihlala zisebenza kumkhawulo omkhulu, lokhu kubonisa ukuthi kunezinkinga eziphelele zokusebenza nokuhlisa kwezindawo zokugcina izinhliziyo. Ukuncipha kwesikhathi sokuhlisa kwezindawo zokugcina izinhliziyo kusiza ukwenza izindlela zokugcina izisebenzi ngokufanele futhi kungasiza ukuncipha izinkinga zokuhlisa kwezindawo zokugcina izinhliziyo emaphakathi amanquma.
