Amakhadi ezithombe (noma ama-GPU) wamatheminali eselula ane-Android aya ngokuya ebaluleke kakhulu uma kuziwa ekulinganiseni ukusebenza kwawo, njengoba ukuziphatha lapho udlala imidlalo kuncike kulokhu - ikakhulukazi uma iqukethe ihluzo ezinezinhlangothi ezintathu, futhi, ezingcono noma ezimbi kakhulu. ukuphathwa kwezithombe eziboniswa esibukweni. Iqiniso liwukuthi imodeli entsha ifika emakethe: I-ARM Mali-G71. Sizokutshela konke mayelana nale ngxenye.
Le GPU bekuyintuthuko ye-Mali yamanje (T880, engatholakala kumadivayisi afana ne- I-Galaxy S7, neprosesa yayo ye-Exynos), ngakho ifuna ukuthuthukisa ukusebenza futhi, vele, yehlise ukusetshenziswa. Futhi, ngenxa yalokhu, i-architecture entsha ibalwe, ebizwa I-Bifrost - Ukushiya ngemuva, ngakho-ke okuthiwa uMidgard-. Ngakho-ke, amagama anezikhombo zezinganekwane zamaNorse ayagcinwa.
Emininingwaneni yokuthuthukisa ukhonkolo, inkampani imemezele ukuthi i-ARM Mali-G71 isebenza kahle ngo-20% esigabeni samandla -ekuhlolweni okwenziwa ngaphansi kwezimo ezifanayo kune-T880-, ngakho-ke amabhethri ashesha kancane. Ngaphezu kwalokho, amandla abo okuphatha ulwazi aphakeme futhi, emi ku-40%. Ngakho-ke, kufinyelelwa ukuthi isikhala esincane ama-GPU anaso ngaphakathi kwamaphrosesa sisetshenziswe kangcono kakhulu futhi sikhuluma ngomsebenzi omuhle ngempela womkhiqizi nomklami.
Kufezwa kanjani lokhu?
Yebo, ukwandisa izakhi ezibalulekile ezakha ikhadi lehluzo lapho usebenza, njenge "cores shader". Lezi zihambile zisuka ku-16 zemodeli yamanje zaya ku-32, eziphinda kabili umthamo wayo namandla okusebenza. Eminye imininingwane ebalulekile ye-ARM Mali-G71 entsha ukuthi ivumela ukusebenza nge 120 Hz imvamisa ephezulu -ilungele izindawo ezingokoqobo- futhi, ngaphezu kwalokho, iyakwazi ukusebenza nezinqumo ze-4K nokudala ukuncishiswa kwemingcele yamasampula amaningi (anti-aliasing). Ukusondelana nokududuza kwegeyimu, akungabazeki.
Njengoba kungeke kube ngenye indlela, i-ARM Mali-G71 iyahambisana ne-API intabamlilo -okuzobaluleka esikhathini esizayo esiseduze sobuchwepheshe beselula ngokukhulula ama-CPU omsebenzi-. Ngaphezu kwalokho, kuhlanganisa ubuchwepheshe I-CoreLink CCI-550, okuvumela ikhadi lezithombe kanye nama-processor cores ukuthi asebenzise imemori efanayo, okunciphisa isikhathi lapho usebenza nedatha (ukwandisa ukusebenza ngo-1,5 uma kuqhathaniswa ne-T80).
I-Quad Vectorization nokunye
Lokhu kungenye yezinto ezinhle kakhulu ze-ARM Mali-G71 GPU, njengoba ivumela umsebenzi kumjikelezo wewashi ukuthi wenziwe ngesivinini esikhulu ngaphandle kokulahlekelwa ukuzinza noma ukwandisa izinga lokushisa. Kusho ukuthini lokhu ukuthi ukwakhiwa kwezithombe ezinobukhulu obuthathu (izimbazo X, Y kanye no-Z) kwenziwa ngaphambili, okuvumela ukuthi ukusebenza kukhulu. ngokushesha. Ngakho-ke, inani elifanayo lolwazi lilawulwa ngaphambili, elibalulekile kumadigri athuthukile.
Obunye ubuchwepheshe obusetshenziswa yi-ARM Mali-G71 bubizwa I-Quad Manager. Ngalokhu kusengaphambili, imiyalelo eyenziwayo ihlelwe ngendlela ephumelela kakhudlwana, ukuze ukuhlanganiswa kwayo nokuthumela okulandelayo esikrinini kube lula ku-hardware futhi, ngakho-ke, ukuzinza kukhulu futhi ukusetshenziswa kwamandla kuphansi. Ukwengeza, izithunzi neminye imiphumela ethuthukisiwe nayo iyathandwa.
Esimemezelweni se-ARM Mali-G71 GPU entsha kuboniswe ukuthi amamodeli okuqala azosebenzisa ama-processor anale ngxenye azofika 2017, ngakho-ke abakhiqizi sebevele basebenza ekusetshenzisweni kwayo. Ngakho-ke, ukucabanga ukuthi i-Samsung Galaxy S8 iyayisebenzisa kuyasebenza ngokuphelele. Futhi, lokhu kungaba ukweqa kwekhwalithi uma udlala futhi, vele, kwe Iqiniso eliyiqiniso.
