I-HAGS kunye ne-Resizable BAR: kufuneka uzivule nini ngokwenene?

Kwiminyaka yakutshanje, ii-levers ezimbini zokusebenza ziye zavelisa ingxoxo eninzi phakathi kwabadlali kunye nabathandi bePC: I-Hardware-Acceleated GPU Scheduling (HAGS) kunye ne-Resizable BAR (ReBAR)Zombini zithembisa ukucudisa yonke ithontsi yokugqibela yokusebenza kwisakhelo ngasinye, ukuphucula ukuguda, kwaye, kwiimeko ezithile, ukunciphisa ukubambezeleka, kodwa akusoloko kububulumko ukubenza bangaboni. Apha siye saqulunqa esikubonileyo kuvavanyo, izikhokelo, kunye neengxoxo zoluntu ukuze wenze isigqibo esinolwazi malunga nokuba kufanelekile nini ukuzilungisa.

Isibane sikhanyisa ngakumbi I-BAR enokulungiswa kwakhona kumakhadi e-NVIDIANangona inkampani iyixhasile izizukulwana, ayikwenzi ngokuzenzekelayo kuyo yonke imidlalo. Isizathu silula: ayizizo zonke izihloko ezenza ngcono, kwaye kwezinye, iFPS inokuhla. Nangona kunjalo, kukho imizekelo esebenzayo kunye nebenchmarks apho ukwenza ngesandla i-ReBAR-nakwihlabathi jikelele ngezixhobo eziphambili-ivelisa iinzuzo ezibonakalayo ubuncinane ze-1% kwiibenchmarks zokwenziwa ezidumileyo. Masifunde konke ngayo. I-HAGS kunye ne-BAR enokuphinda isetyenziswe: ukuba zisebenze nini.

Ziziphi ii-HAGS kunye ne-Resizable BAR kwaye kutheni zibalulekile?

IHAGS, okanye udweliso lwe-GPU olukhawuleziswe ngehardwareItshintsha inxalenye yolawulo lomgca wegrafiki ukusuka kwi-CPU ukuya kwi-GPU ngokwayo, inciphisa umphezulu weprosesa kunye nokubakho kwe-latency. Impembelelo yayo yokwenyani ixhomekeke kumdlalo, abaqhubi, kunye nenguqulelo yeWindows, ke ezinye iinkqubo zifumana ukuphucuka okubonakalayo. abanye apho kungekho nto iguqukayo okanye ide inciphise uzinzo.

I-ReBAR, inxalenye yayo, yenza ukuba i-PCI Express ibonakale ivumela i-CPU ukuba ifikelele yonke i-GPU VRAM endaweni yokunqunyulwa kwiifestile ezingama-256MB. Oku kunokukhawulezisa ukunyakaza kwedatha okufana nokuthungwa kunye ne-shaders, okukhokelela kubuncinci obungcono kunye nokuhambelana ngakumbi xa umboniso utshintsha ngokukhawuleza-into eluncedo ngakumbi ihlabathi elivulekileyo, ukuqhuba kunye nesenzo.

I-Resizable BAR isebenza njani kwinqanaba lobugcisa

Ngaphandle kwe-ReBAR, ukudluliselwa phakathi kwe-CPU kunye ne-VRAM kwenziwa nge isithinteli esisisigxina se-256 MBXa umdlalo ufuna amandla okuqhubela phambili, uphindaphindo oluninzi lubotshelelwa kunye, luzisa imigca eyongezelelweyo kunye ne-latency phantsi komthwalo onzima. Nge-ReBAR, obo bukhulu buba bungaphinda bukhule, buvumela ukuyilwa... iifestile ezinkulu nezingqameneyo ukuhambisa iibhloko ezinkulu zedatha ngokufanelekileyo.

Kwi-PCIe eqhelekileyo ye-4.0 x16 ikhonkco, i-bandwidth ijikeleze 31,5 GB / sUkusetyenziswa ngcono kwalo mbhobho kuthintela imiqobo ngexesha losasazo olunzima lomthombo. Ngokuziqhelanisa, i-GPU ene-VRAM eninzi inokudlulisa idatha ngokuqhekeka okuncinci, kunye ne-CPU ulawula umsebenzi omninzi ngaxeshanye, endaweni yokubeka yonke into emgceni.

Ukuhambelana, iimfuno, kunye nesimo senkxaso kwi-NVIDIA kunye ne-AMD

I-ReBAR ikhona kwiinkcukacha ze-PCIe ixesha elithile, kodwa ukuthunyelwa kwayo kwizicelo zabathengi kuye kwafumana amandla emva... I-AMD iya kwenza i-Smart Access Memory idume (SAM) kuluhlu lweRyzen 5000 kunye neRadeon RX 6000. I-NVIDIA yamkele isiseko sobuchwephesha esifanayo (uyibiza nje ngokuba yiResizable BAR) kwaye yathembisa ukuyivula kusapho. GeForce RTX 30.

I-NVIDIA ithotyelwe ngokudibanisa inkxaso kubaqhubi kunye ne-VBIOS, nangona ukusebenza komdlalo ngamnye kuhlala kunemiqathango izintlu eziqinisekisiweyoNgokukodwa, iGeForce RTX 3060 yakhululwa ngokuhambelana neVBIOS; kwakuyimfuneko kwi-3090, 3080, 3070, kunye ne-3060 Ti. ukuhlaziya iVBIOS (UHlelo lwabaseki oluvela kwiwebhusayithi ye-NVIDIA, kunye neemodeli zokuhlanganisa ukusuka kwiwebhusayithi yomenzi ngamnye). Ukongeza, oku kulandelayo kuyafuneka Umqhubi weGeForce 465.89 WHQL okanye ngaphezulu.

Kwiprosesa kunye necala lebhodi yomama, a CPU ehambelanayo kunye ne-BIOS eyenza i-ReBAR. I-NVIDIA iqinisekisile inkxaso kunye ne-AMD Ryzen 5000 (i-Zen 3) kunye ne-10 kunye ne-11th isizukulwana se-Intel Core processors. chipset ezixhaswayo ziquka AMD 400/500 motherboards series (nge BIOS efanelekileyo) kunye, Intel, Z490, H470, B460, kunye H410, kwakunye 500 series usapho. Vuselela "Ngaphezulu kwe-4G i-Decoding" kunye "neNkxaso yoBukhulu be-BAR" Ngokuqhelekileyo kubalulekile kwi-BIOS.

Ukuba usebenzisa i-AMD kwinqanaba le-CPU+GPU, i-SAM isebenza ngendlela ebanzi kwaye inokusebenza ngayo yonke imidlaloNge-NVIDIA, inkxaso inqunyelwe kwizihloko eziqinisekisiweyo yinkampani, nangona inokunyanzeliswa ngesandla ngezixhobo eziphambili, kucingelwa umngcipheko ohambelana nawo.

Uluhlu lwemidlalo eqinisekisiweyo kwaye apho inzuzo ibonakala khona

Ngokutsho kwe-NVIDIA, impembelelo inokufikelela ukuya kuthi ga kwi-12% kwizibambiso ezithile Phantsi kweemeko ezithile. Inkampani igcina uluhlu lwemidlalo eqinisekisiweyo, ebandakanya:
