David Hanak Namuhla kumakwe amaphrosesa amasha avela ku-Intel. Ekuseni, ama-chips okuqala esizukulwane sesi-8 esibizwa nge-Kaby Lake refresh yethulwa ngokusemthethweni. Kuze kube manje, sesimemezele ama-chips angu-15W okonga amandla ochungechungeni anegama langaphakathi elithi U, amanye amamodeli omndeni okufanele alandele. Endabeni yamaphrosesa angu-15W, lawa amamodeli avela ezincwadini zamanothi nakwamanye amadivaysi aphathekayo. Ngokolwazi lokuqala, kubukeka sengathi sisohlangothini olubalulekile lokushintsha ukusebenza.
Ukwethulwa okusemthethweni namuhla kwandulelwe ukuputshuka okukodwa kwangesonto eledlule. Nokho, besifuna ukulinda imininingwane esemthethweni. Namuhla ekuseni i-Intel igcine yethule amamodeli we-i5 8250U, 8350U kanye ne-i7 8550U kanye ne-8650U.
Mayelana nezakhiwo, lena ngokuyisisekelo i-chip efanayo neyesizukulwane samanje se-Kaby Lake processors. Ngakho-ke ukuvuselela kwe-Kaby Lake kuwukuguquguquka okuncane (njengoba igama libonisa) okusebenzisa inqubo yokukhiqiza elungiswe kancane. Kodwa-ke, ushintsho olukhulu kakhulu inani lama-cores. Esikhundleni sezixazululo zokuqala ezikabili-core, amaphrosesa amasha angokwemvelo angama-quad-core (kanye ne-Hyper Threading). Ngenani elifanayo nangaphansi kwezimo zokusebenza ezifanayo, abasebenzisi manje bazothola ukusebenza okwengeziwe.
Ingabe konke kuzwakala kukuhle kakhulu? Uma kuqhathaniswa nesizukulwane sangaphambilini, amawashi ehle kancane, nakuba amaza e-Turbo Boost asephezulu kakhulu. Ukwanda kwama-cores kuphinde kwathinta usayizi we-cache ye-L3, manje esenamandla angu-6 noma 8MB. Ukusekelwa kwenkumbulo kuyafana nakuma-chips e-Kaby Lake okuqala, okungukuthi i-DDR4 (entsha max 2400MHz) kanye ne-LPDDR3 (i-LPDDR4 ngakho-ke ayenzeki futhi, kuzodingeka silinde lokho kuze kube unyaka ozayo, ngokufika kwe- Izakhiwo zeCannon Lake). Ukusebenza kwezithombe ezihlanganisiwe akushintshile. Kungezwe amasethi eziyalezo ezintsha kuphela nosekelo lwendabuko lokulungiswa kwe-UHD nge-HDMI 2.0/HDCP 2.2.
Ungabona ukuqhathaniswa kwesizukulwane esisha nesidala ngezansi. Kumthengi ojwayelekile, amaphrosesa amasha asho ukukhuphuka okukhulu ekusebenzeni, ngaphandle kokukhuphuka kwentengo. Kodwa-ke, ukuthi amaphrosesa amasha azosebenza kanjani akwaziwa kakhulu. Ikakhulukazi engxenyeni ye-chip ye-15W, ibivele ishisa kakhulu. Lawa maphrosesa ngokuvamile avela emikhiqizweni engazange igqame ngokupholisa okunamandla kakhulu. Njengoba inani lama-cores liphindwe kabili, kuzojabulisa ukubona ukuthi amaphrosesa amasha asebenza kanjani kuma-laptops amasha, ikakhulukazi maqondana ne-CPU throttling.

Ukwehliswa kwamabhithi ayisisekelo akubonakali njengokungabalulekile kimi!
Isikhathi esiningi i-frequency izophakanyiswa noma kunjalo, ngenxa ye-Turbo Boost. Kuzobonakala ekusebenzeni ukuthi kuzoba njani ngokupholisa kumafrikhwensi aphezulu.
Kunjalo, ukuncishiswa kwewashi lesisekelo ngo-25% ngokwesilinganiso.
Kodwa-ke, ngesivinini sewashi eliyisisekelo, lezo zinto ezincane ngeke zishise kakhulu ... ngakho-ke kuzoncika kakhulu ekupholiseni, ukuthi kuzohambisana kangakanani ne-Turbo Boost...
Hhayi-ke, kuhlale kumayelana nesigqi (ngaphezu kwalokho, kumayelana nemvamisa eyisisekelo, esetshenziswa kakhulu uma inikwa amandla yibhethri). Into yokuqala ukuthi lapho usunama-cores amaningi ngokomzimba, ungakwazi ukukhokhela ukwehlisa iwashi lesisekelo. Okwesibili ukuthi akuzona zonke iziqondiso eziphela ngempumelelo okokuqala. Isibonelo, yehluleka izikhathi eziyi-1000 ngaphambi kokuthi iqedwe ngempumelelo. Isikhathi lapho uthuthukisa khona iphrosesa ukuze umyalelo onikeziwe wehluleke izikhathi ezingu-300 kuphela, isibonelo, awusakudingi ukusebenza okunjalo ukuze uhambisane nesikhathi lapho umyalelo wehlulekile. Yiqiniso, okwamanje lapho i-notebook isebenza kusukela emthonjeni, iphrosesa ingakwazi ukwedlula i-overclocked ngisho nemvamisa ephezulu futhi inganikeza ukuphumula, isibonelo.
Angisho ukuthi lesi yisona sizathu esenza ukuthi izinga lewashi lincishiswe, kodwa ukuthi lezi zici zingathinta futhi imvamisa yesisekelo sephrosesa.
