Umahluko phakathi kwe-DirectStorage kunye ne-NVMe eqhelekileyo

La irrupción de I-DirectStorage kunye ne-NVMe SSDs itshintshe indlela esifumana ngayo umdlalo wePC. Kancinci kancinci, siye sahamba ekunyamezeleni ukulayisha okungapheliyo kunye namaxesha okulinda ukuba singawaqapheli, kodwa kuseyinto eqhelekileyo ukuba kuvele imibuzo: Ngowuphi umahluko phakathi kweDirectStorage kunye neNVMe eqhelekileyo?

Kweli nqaku sihlalutya lo mbandela, sikwacacisa ukuba zombini itekhnoloji iyancedisana njani. Kunomdla omkhulu kwabo bafuna amava ePC yokugqibela.

Yintoni uGcino oluNgqo kwaye luyichaphazela njani imidlalo?

Kwiminyaka yakutshanje, ulindelo olukhohlakeleyo luye lwenziwa ngeenxa zonke DirectStorage, i-API ephuhliswe nguMicrosoft kwaye yaqala yafakwa kwi-Xbox Series X/S kwaye ngoku ingaphakathi Windows 10 kunye ne-11. Injongo yayo kukuba ukwandisa isantya sokufikelela kwidatha kwimidlalo, ukuvumela ihlabathi elikhulu, ukuthungwa okuneenkcukacha, kwaye okona kubaluleke kakhulu, ukunciphisa ixesha lokulayisha ukuya phantse zero.

Uyenza njani loo nto? Ewe, ngotshintsho olukhulu kwinkqubo yokulayisha izixhobo. Indlela yendabuko ibandakanya i-CPU ejongene nokukhupha idatha kwisitoreji (i-SSD okanye i-HDD), i-decompressing kwi-RAM, kwaye ekugqibeleni ihanjiswe kwikhadi lemifanekiso (GPU). Oku kuveliswa imiqobo, ngakumbi xa imizobo kunye nokwenziwa kwaqala ukukhula ngokukhawuleza kubungakanani kunye neenkcukacha.

Isitshixo kwi-DirectStorage kukususa i-CPU kwi-equation yokudlulisa kunye nokudiliza le datha. Ngoku ulwazi luyadlula ngqo ukusuka kwi-NVMe SSD ukuya kwiGPU kakhulu ngokufanelekileyo. Kwaye kwiinguqulelo zamva nje, i-GPU iyakwazi ukwenza i-decompression ngokwayo. Konke oku kuguqulela kwi ukulayisha okukhawulezileyo kunye nokuguquguquka okukhulu kwimidlalo yethu.

Ngamagama alula: DirectStorage Sisitshixo sokukhulula amandla apheleleyo e-NVMe SSDs ekudlaleni, into ethe de kwaba mva nje ibikhethekile kwi-gen-gen consoles.

Yintoni eyahlula ii-NVMe SSDs kwezinye iidrive?

Xa sithetha nge iyunithi yokugcina, azifani zonke. I I-NVMe SSD (I-Non-Volatile Memory Express) sebenzisa i-interface ye-PCI Express, evumela ukufunda nokubhala isantya esiphezulu kakhulu kunezo ze-SATA SSD zendabuko (kwaye kunjalo, ii-HDD ezindala zoomatshini).

Ukukunika ingcamango, i-SATA SSD inika ngokuqhelekileyo isantya phakathi kwe-500 kunye ne-600 MB / s, ngelixa i-PCIe 3.0 NVMe SSD inokufikelela kwi-3500 MB / s kunye ne-PCIe 4.0 entsha okanye i-5.0 inokudlula i-7.000 MB / s. Lo mahluko ukhohlakele kwaye ivula umnyango kumathuba amatsha, ngakumbi xa idityaniswe neteknoloji efana neDirectStorage.

Oko kwatshoyo, ngaphandle kokuba ne-NVMe SSD ekhawulezayo, de kube sekufikeni kwe DirectStorage, imidlalo ayikwazanga ngokwenene ukuthatha ithuba la manani njengoko kwakusekho imiqobo ekudluliseleni idatha ukusuka kwindawo yokugcina ukuya kwikhadi lemizobo.

Indlela i-DirectStorage esebenza ngayo kunye ne-NVMe SSDs: Isibini esigqibeleleyo

Owona mtsi mkhulu wobunjani obukhoyo DirectStorage kukutshintsha ukuhamba kwedatha kwimidlalo yakho. Ngoku, izixhobo (iimodeli ze-3D, i-Ultra-detailed textures, i-animations) ezadlulayo kwi-CPU kunye ne-RAM, Baza phantse ngokuthe ngqo kwi-NVMe SSD ukuya kwiGPU, ukuvumela yonke inkqubo ukuba ikhawuleze kwaye isebenze ngakumbi.

Kuhlaziyo lwamva nje lwe-DirectStorage (efana nenguqulo 1.2 esanda kukhutshwa), iye yalungiselelwa khulula umthwalo we-CPU, ngenxa yokunciphisa idatha ngokuthe ngqo kwi-GPU. Oku akunciphisi ixesha lokulayisha kuphela, kodwa kukwanceda ukukhulula izixhobo zeprosesa zeminye imisebenzi, efana nobukrelekrele bokwenziwa, umdlalo wefiziksi, okanye naziphi na izibalo ezinzima.

Le nkqubela phambili yobugcisa iqala ukubonakala kwimidlalo emininzi yakutshanje, nangona ikhathalogu isencinci. Forspoken Yayiyeyokuqala ukuyamkela, ecaleni kwezihloko ezifana neRatchet kunye noClank: Rift Apart, Forza Motorsport, okanye izithembiso ezizayo ezifana neziqwenga zeDiablo IV kunye nezinye izinto ezinkulu ezikhutshwayo. Kuzo zonke ezi zihloko sele kubonakala ukuba, Nge-NVMe SSD kunye ne-DirectStorage enikwe amandla, i amaxesha okulayisha mancinci kunye namava emidlalo aziva egudile.

Kuthatha ntoni ukuthatha ithuba kwiDirectStorage?

Ukuthatha inzuzo ye DirectStorage, iPC yakho idinga ukuhlangabezana ezimbalwa ubuncinci beemfuno:

• Inkqubo yokusebenza yeWindows 11 (Windows 10 ixhasa uguqulelo olulinganiselweyo, kodwa i-11 iyacetyiswa ukuba isetyenziswe ngokupheleleyo.)
• NVMe PCIe 3.0 SSD okanye ngaphezulu. Iidrive zeSATA azikho kumbuzo wale teknoloji.
• Ikhadi lemizobo elihambelanayo leDirectX 12. UMicrosoft ucebisa ngakumbi i-NVIDIA's RTX 20/30 kunye ne-AMD's RX 6000 GPUs, ebonisa i-hardware decompression accelerators.

Kude kube mva nje, iMicrosoft ibifuna ii-SSD zibenobuncinci be-1 TB yomthamo, nangona le mfuneko sele isusiwe. Ekuphela kwento oyifunayo yi-NVMe drive enePCIe 3.0 okanye ujongano oluphezulu.

Iinzuzo zangempela: amaxesha okulayisha kunye nokusebenza

Kuyinto eqhelekileyo ukubuza: Ngaba ngokwenene kukho umahluko? Impendulo emfutshane nguewe, nangona kuxhomekeke kumdlalo kunye ne-hardware. Kwiimvavanyo ezinezihloko ezihambelanayo ezifana ne-Forspoken, umahluko phakathi kweentlobo zediski notable:

• I-NVMe PCIe 4.0/3.0 SSD: Ukulayisha amaxesha ukusuka kwi-1,3 ukuya kwi-2,5 imizuzwana.
• SATA SSD: Ilayisha malunga ne-5,8 ukuya kwi-7,5 imizuzwana.
• I-HDD yesiNtu: Ukuya kuthi ga kwimizuzwana engama-50!

Umahluko ubonakala ngakumbi xa kufikwa ekulayisheni imihlaba evulekileyo okanye ukuthungwa okukhulu, nangona kweminye imidlalo yokuqala impembelelo yayingaphantsi kunoko bekulindelekile (umzekelo, kwi-Forspoken, amaxesha okulayisha kwizizukulwana ezahlukeneyo ze-SSD ngamanye amaxesha ayefana). Undoqo kukuba njengoko abaphuhlisi belungiselela imidlalo yabo yeDirectStorage, le yantlukwano iya kuqhubeka ikhula.

Kodwa kukho enye inkalo ebaluleke ngakumbi: impembelelo kwi-FPS kunye nokumanzi. Ngoxinzelelo lwe-GPU kunye nokunciphisa umthwalo we-CPU, uphuculo olubalulekileyo luye lwabonwa. I-6% yokuphucula kwi-avareji ye-FPS kwaye ukuya kuthi ga kwi-12% kwi-FPS encinci xa uhamba ukusuka kwi-SATA SSD ukuya kwi-PCIe 4.0 NVMe SSD, ngokukodwa kwiindawo ezinzima okanye imithwalo evulekileyo yehlabathi.

Ukuhambelana, ulungelelwaniso kunye nophuculo olutsha

I-DirectStorage 1.2, inguqulelo yamva nje, ibandakanya iinketho zokuphucula ukuhambelana needrive ezindala ngokusebenzisa Ukunyanzeliswa kwe-IO. Nangona kunjalo, iMicrosoft incoma kuphela ukuyivumela ukuba usebenzisa ii-HDD ezicothayo, njengoko ukusebenza kusesemva kwee-SSD zanamhlanje.

Enye into entsha yi-API GetCompressionSupport, evumela umphuhlisi ukuba azi ukuba i-decompression yenziwa yi-GPU okanye i-CPU, inceda ukunyusa ukusebenza. Ukongeza, uhlaziyo ngalunye lubandakanya ukulungisa iibhagi kunye nokulungiswa okuphucula ngakumbi ubudlelwane phakathi kwe-DirectStorage kunye nolungelelwaniso lwehardware eyahlukeneyo.

Into ekufuneka uyigcine engqondweni: Ukusebenzisa i-DirectStorage kuthetha ukuba uya kufuna i-RAM eninzi, njengoko inkqubo igcina imemori eyongezelelweyo ukuhambisa idatha phakathi kwe-SSD kunye ne-GPU. Kwiikhompyuter zangoku, oku akusoloko kuyingxaki, kodwa kufanelekile ukukhumbula ukuba unolungiselelo olungqongqo.

Unyino olunokubakho kunye nemingeni ye-DirectStorage

Ewe kulungile I-DirectStorage ithembisa ukukhulula amandla e-SSD kunye nokuguqula amava emidlalo, inyaniso kukuba ukwamkelwa kwabantu abaninzi kusendleleni. Kukho imingeni yobugcisa ekuphunyezweni, kwaye kwezinye iimeko kuye kwaxelwa ukuba ukuchithwa kwe-GPU ngokwayo kunokuphazamisana neminye imisebenzi enzima ukuba imizobo ilayishwe kakhulu (umzekelo, kwimidlalo enokulandelwa kwe-ray okanye i-DLSS inikwe amandla).

Abaphuhlisi bakwajongene nomceli mngeni we ukuyila ngokutsha indlela abalawula ngayo impahla yokudlala. Ukudala ihlabathi elityebileyo, elineenkcukacha ezininzi-ezineemodeli eziphezulu ze-polygon kunye ne-ultra-realistic textures-kufuna ingqondo entsha kunye nezixhobo eziphakamisa indlela ethe ngqo ye-SSD-to-GPU.

Ngaphandle kwezi ziphazamiso zincinci zokuqala, amandla asekhona. Amanani ekucuthweni kokusetyenziswa kwe-CPU (ukuya kuthi ga kwi 85% ngaphantsi kwezinye iimvavanyo), ukwanda kweFPS kunye nokupheliswa phantse kwamaxesha okulayishwa ziingxoxo ezinyanzelisayo kushishino lokudlala ukuba luqhubele phambili kweli cala.

Ikamva lemidlalo lilele ekudityanisweni kwetekhnoloji efana neDirectStorage kunye nokusetyenziswa kwe-NVMe SSDs, eya kuvula indlela yelizwe elineenkcukacha, ngokukhawuleza, kunye nokumangalisayo. Ukwenza obu bugcisa busebenze, ngaphandle kwamathandabuzo, lolona tyalo-mali lungcono onokuthi ulwenze ukuphucula amava akho okudlala kwiminyaka ezayo.
