Ithimba labacwaningi abavela kumanyuvesi amaningana ase-US lenze indlela entsha yokuhlasela yesiteshi eseceleni ebavumela ukuthi baphinde badale ulwazi olubonakalayo olucutshungulwe ku-GPU. Ngokusebenzisa indlela ehlongozwayo, ebizwa nge-GPU.zip, umhlaseli anganquma ulwazi oluboniswa esikrinini. Phakathi kwezinye izinto, ukuhlasela kungenziwa ngesiphequluli sewebhu, isibonelo, ukubonisa ukuthi ikhasi lewebhu elinonya elivulwe ku-Chrome lingathola kanjani ulwazi mayelana namaphikseli abonisiwe lapho kunikezwa elinye ikhasi lewebhu elivulwe kusiphequluli esifanayo.
Umthombo wokuvuza kolwazi wukulungiselelwa okusetshenziswa kuma-GPU wesimanje okunikeza ukucindezelwa kwedatha eyingcaca. Inkinga yenzeka uma kusetshenziswa ukucindezelwa kuwo wonke ama-GPU ahlanganisiwe ahloliwe (AMD, Apple, ARM, Intel, Qualcomm) kanye namakhadi ezithombe ze-NVIDIA discrete. Ngasikhathi sinye, abacwaningi bathola ukuthi i-Intel ne-AMD GPU ehlanganisiwe ihlale ivumela ukucindezelwa kwedatha yehluzo, noma ngabe uhlelo lokusebenza aluceli ngokuqondile ukusetshenziswa kwalokhu kulungiselelwa. Ukusetshenziswa kokuminyanisa kubangela ithrafikhi ye-DRAM nomthwalo wenqolobane ukuthi uhlobane nemvelo yedatha ecutshungulwayo, engakhiwa kabusha ngephikseli ngephikseli ngokuhlaziywa kwesiteshi eseceleni.
Indlela ihamba kancane, ngokwesibonelo, ohlelweni olune-AMD Ryzen 7 4800U GPU edidiyelwe, ukuhlasela kokunquma igama lapho umsebenzisi angena khona kuWikipedia kwenye ithebhu kuthathe imizuzu engama-30 futhi kwenze kwaba nokwenzeka ukunquma okuqukethwe amaphikseli anokunemba okungu-97%. Kuzinhlelo ezine-Intel i7-8700 GPU edidiyelwe, ukuhlasela okufanayo kuthathe imizuzu engama-215 ngokunemba okungu-98%.
Uma uhlasela ngesiphequluli, isayithi eliqondiwe lizungeza i-iframe ukuze liqalise ukunikezela. Ukuze kunqunywe ulwazi oluzoboniswa, okukhiphayo kwe-iframe kuguqulwa kube ukumela okumnyama nokumhlophe, lapho kusetshenziswa khona isihlungi se-SVG, esenza imbondela elandelanayo yamamaski ezethulayo futhi angathuli kakhulu ngesikhathi sokuminyanisa. Ngokusekelwe ekuhlolweni kwezinguquko esikhathini sokudweba samasampuli ezithenjwa, ukuba khona kwamaphikseli amnyama noma akhanyayo endaweni ethile kuyagqanyiswa. Isithombe sisonke sakhiwe kabusha ngokuhlolwa kwe-pixel-by-pixel okulandelanayo kusetshenziswa imaski efanayo.
I-GPU nabakhiqizi beziphequluli baziswe ngale nkinga ngoMashi, kodwa akekho umthengisi osakhiqize ukulungiswa, njengoba ukuhlasela kuyangabazeka ekusebenzeni ngaphansi kwezimo ezingaphansi kwezinhle futhi inkinga iyintshisekelo yethiyori. I-Google ayikanqumi ukuthi izokuvimbela yini ukuhlasela ezingeni lesiphequluli se-Chrome. I-Chrome isengcupheni ngoba ivumela ukulayisha i-iframe kwenye isayithi ngaphandle kokusula Ikhukhi, ivumela izihlungi ze-SVG ukuthi zisetshenziswe ku-iframe, kanye nezithunywa ezinikezela ku-GPU. IFirefox neSafari azithintwa ukuba sengozini ngoba azihlangabezani nalezi zindlela. Ukuhlasela futhi akusebenzi kumasayithi avimbela ukushumeka nge-iframe kwamanye amasayithi (isibonelo, ngokusetha unhlokweni we-X-Frame-Options HTTP enanini elithi “SAMEORIGIN” noma “DENY”, kanye nangezilungiselelo zokufinyelela usebenzisa Okuqukethwe. -Isihloko Senqubomgomo Yezokuphepha ).
