Ngemuva kokwethulwa kwe-MacOS Mojave ku-WWDC yokugcina ka-2018, kwathunyelwa imiyalezo emibili efanelekile: ama-Mac ayezosekela iMacOS Mojave nesinqumo sika-Apple maqondana nokusetshenziswa kwenjini yemidwebo. I-Apple izodonsa i-OpenGL futhi igxile kwi-Metal.
Uhlobo lokuqala lwe-Metal lwalunamalambu alo nezithunzi phakathi kohlelo. Le nguqulo yesibili ilungiselelwe kakhulu izidingo zonjiniyela. Noma kunjalo, ukushiywa kwe-OpenGL kuholele ekuhlaselweni ngabathuthukisi abaningi ekhangise ngokungaqhubeki nokuhlelela i-macOS uma beyeka i-OpenGL.
Ngakolunye uhlangothi, sihlangane namamodeli azosekela iMacOS Mojave. Ngaphandle kweMac Pro, wonke ama-Macs ngaphambi kuka-2012 ngeke esasekelwa. Ngu Siyini isizathu sakho konke lokhu? Kakhulu amandla we-GPU yalezi zinhlobo.
Kepha uma ungeyena umsebenzisi ocindezela amandla we-GPU yakho, ngokuhlelwa kwevidiyo noma izithombe, kungani ulinyazwa? Impendulo itholakala kulokho okwenziwa yi-Metal akusetshenziselwa ukuhlela kuphela. Ezinye izinhlelo ezizosebenza kwi-MacOS Mojave zizodinga i-GPU ne-Metal efanelekayo. Isibonelo, i-FaceTime 5.0, enabasebenzisi abaningi, idinga i-Metal ukwenza ihluzo.
Ukwazi ukusetshenziswa kwe-Metal kumadivayisi we-Apple, kufanele sibuyele emuva kuma-iPhone 5s. Efonini yokuqala enesakhiwo esingu-64-bit. ngalokho, I-Apple ihlose ukwengeza umthwalo we-GPU ngesoftware yokwehlisa umthwalo we-CPU. Eqinisweni, igama elithi Metal lifuna ukufanekisa ukuthi umthwalo odingekayo uhlala esigabeni sangaphambilini sokwelapha, kulokhu, ngensimbi engenalutho, engapholishiwe, ecishe ibe yintombi nto.
Ngakho konke lokhu, i-Apple izimisele ukushiya i-OpenGL ekhabetheni selokhu uSteve Jobs ayikhombisa emphakathini ngasekupheleni kweminyaka yama-90s, ngemuva kokushiya i-QuickDraw 3D. Okusele ukungena kwi-MacOS Mojave yi-Metal 2. Izinto ezintsha ezisezingeni eliphakeme yilezi ukwenziwa ngcono kwezinqubo nokusungula okusha ngokufunda komshini kanye nokungokoqobo okungeziwe.
