Ikhadi levidiyo

Abakhiqizi abaningi be-laptop basanda kusetyenziswa izixazululo ezihlanganisiwe emikhiqizweni yabo njengama-GPU ahlanganisiwe kanye ne-disc. I-Hewlett-Packard yayingahlukile, kepha inguqulo yayo ngendlela ye-Intel processor nehluzo le-AMD libangela izinkinga ngokusebenza kwemidlalo nokusetshenziswa. Namuhla sifuna ukukhuluma ngokushintsha ama-GPUs enhlanganisweni enjalo kumalaptop we-HP.

Imvamisa, izibuyekezo zesistimu ze-GPU ziletha ukuthuthukiswa kokusebenza kanye nokusekelwa kobuchwepheshe obusha. Kwesinye isikhathi, nokho, umphumela ophikisanayo uyabonakala: ngemuva kokuvuselela abashayeli, ikhompyutha iqala ukusebenza kubi kakhulu. Ake sibone ukuthi kungani lokhu kwenzeka nokuthi ungalungisa kanjani lolu hlobo lokwehluleka.

Iningi labaprosesa banamuhla linomsuka wehluzo owakhelwe ngaphakathi ohlinzeka ngezinga elincane lokusebenza ezimweni lapho isisombululo se-discrete singatholakali. Kwesinye isikhathi i-GPU ehlanganisiwe idala izinkinga, futhi namhlanje sifuna ukungenisa izindlela zokuyikhubaza. Ukukhubaza ikhadi levidiyo elihlanganisiwe Njengoba umkhuba ukhombisa, iprosesa elihlanganisiwe lehluzo alidingi ukuholela ezinkingeni kuma-desktop e-PC, futhi amalaptop amaningi avame ukuba nenkinga yokungasebenzi kahle, lapho isixazululo se-hybrid (ama-GPU amabili, esakhelwe ngaphakathi nesehluleki) kwesinye isikhathi singasebenzi njengoba bekulindelekile.

Abasebenzisi bama-PC womabili ama-desktop kanye namalaptops bavame ukuthola ibinzana elithi "ikhadi le-chip levidiyo." Namuhla sizozama ukuchaza ukuthi asho ukuthini la magama, futhi sichaze nezimpawu zenkinga. Yini i-chip blade Okokuqala, ake sichaze ukuthi kusho ukuthini igama elithi "chip blade". Incazelo elula kunazo zonke ukuthi ubuqotho bokuthengiswa kwe-chip ye-GPU ku-substrate noma ngaphezulu kwebhodi kwephulwe.

Manje amakhadi amaningi ehluzo le-NVIDIA afakiwe kumakhompiyutha amaningi nakuma-laptops. Izinhlobo ezintsha zamakhadi wehluzo avela kulo mkhiqizi akhululwa cishe njalo ngonyaka, kanti ezindala ziyaxhaswa zombili ekukhiqizeni nangokwezibuyekezo zesoftware. Uma ungumnikazi wekhadi elinjalo, ungenza ushintsho olunemininingwane kumakhasi wemifanekiso woqapha nohlelo lokusebenza, olwenziwa ngohlelo olukhethekile lokuphathelene olufakwe nabashayeli.

Izimayini inqubo yezimayini ye-cryptocurrency. Okudume kakhulu yiBitcoin, kepha kunezimali eziningi eziningi futhi igama elithi "Izimayini" lisebenza kubo bonke. Kuyinzuzo enkulu ukukhiqiza usebenzisa amandla ekhadi levidiyo, ngakho-ke abasebenzisi abaningi benza lolu hlobo lokwenqaba ukumba izimayini kumprosesa.

Kwesinye isikhathi, ngokuchayeka isikhathi eside kumazinga okushisa aphezulu, amakhadi wevidiyo adayiswa ku-chip yevidiyo noma kumemori chip. Ngenxa yalokhu, kuphakama izinkinga ezahlukahlukene, kusukela ekuveleni kwezinto zakudala nemigoqo yemibala esikrinini, iphela ngokuntuleka okuphelele kwesithombe. Ukulungisa le nkinga, kungcono ukuxhumana nesikhungo senkonzo, kepha ungakwenza okuthile ngezandla zakho.

Eminyakeni yamuva, izimayini ze-cryptocurrency zithola ukuthandwa ngokwengeziwe futhi abantu abaningi abasha beza kule ndawo. Ukulungiselela ukusebenza kwezimayini kuqala ngokukhethwa kwemishini efanelekile, imvamisa imayini yenziwa kumakhadi wevidiyo. Inkomba eyinhloko yenzuzo isilinganiso se-hash. Namuhla sizokutshela ukuthi unganquma kanjani isilinganiso se-hash se-remelerator yehluzo futhi ubale ukubalwa kwemali ekhokhelwayo.

Ukuthuthukiswa nokukhiqizwa kwamamodeli wokuqala wamakhadi wevidiyo kwenziwa yi-AMD neNVIDIA, eyaziwa kakhulu ezinkampanini eziningi, kodwa ingxenye encane kuphela yama-accelerators wehluzo evela kulaba bakhiqizi engena emakethe enkulu. Esikhathini esiningi, izinkampani zozakwethu zifika zizosebenza ngokuhamba kwesikhathi, ziguqula ukubukeka nemininingwane ethile yamakhadi njengoba ebona kufanele.

Uma ikhompyutha ivuliwe, uzwa amasignali omsindo bese ubona amasiginali akhanya kuleli cala, kepha isithombe asibonisiwe, khona-ke inkinga ingalala ekungasebenzi kahle kwekhadi levidiyo noma ukuxhumana okungalungile kwezakhi. Kulesi sihloko, sizobheka izindlela ezimbalwa zokuxazulula inkinga lapho i-adaptha yehluzo ingasidluliseli isithombe kumqaphi.

Emidlalweni, ikhadi levidiyo lisebenza ngokusebenzisa inani elithile lezisetshenziswa zalo, ekuvumela ukuthi uthole ihluzo eziphakeme kakhulu ne-FPS ekhululekile. Kodwa-ke, kwesinye isikhathi i-adaptha yehluzo ayisebenzisi wonke amandla, yingakho umdlalo uqala ukunciphisa ijubane futhi ubushelelezi buchitheke. Sinikeza izixazululo eziningana zale nkinga.
