Ngenxa yesibuyekezo sakamuva somshayeli, amakhadi ehluzo e-GeForce 10 kanye ne-16 afunde ukulandelela ama-ray emidlalweni enikwe amandla i-DXR. on и (kanye nanoma imaphi amanye amamodeli e-NVIDIA, ngaphandle kwe-GeForce RTX nama-accelerator amadala kuma-chips e-Pascal) lo msebenzi kunalokho usebenza kumodi yedemo kunokuba ube nanoma yiliphi inani elingokoqobo. Kodwa noma ukulandelela kwe-ray yesikhathi sangempela kungewona amandla e-GeForce GTX 1660, lokhu akuphazamisi ezinye izinzuzo zelungu elincane kakhulu lomndeni wakwaTuring. I-GeForce GTX 1060 ilahlekelwe isikhalazo sayo sangaphambili, futhi ibhalansi yamandla phakathi kwamakhadi ehluzo entengo emaphakathi isishintshile yavuna iRadeon RX 580 futhi. , nokho, imikhiqizo emisha ku-chip ye-TU116 ibuyisele ngokushesha i-NVIDIA esikhundleni sobuholi.
Ekubuyekezweni kwamakhadi wevidiyo asebenza kahle kakhulu, ukunaka kwabezindaba kuvame ukugxila kumamodeli abizayo anezinhlelo zokupholisa ezinamandla, ukwakheka okuhlaba umxhwele kanye nezici eziningi ezengeziwe. Kodwa uma kukhulunywa ngensimbi eningi, kubaluleke kakhulu ukufunda izikhundla eziphansi zohlu lwamanani. Ukusetshenziswa kwamandla okuphansi kwe-GeForce GTX 1660 kukuvumela ukuba wenze lula kakhulu izintambo zekhadi levidiyo, kuyilapho ngesikhathi esifanayo ugcina umkhawulo omkhulu wokuphepha we-overclocking. Ake sifunde izinga lapho ukwenza lula kugcina amandla okugcwala ngokweqile kusetshenziswa isibonelo se-Inno3D GeForce GTX 1660 Twin X2.
Izici zobuchwepheshe, ububanzi bokulethwa, amanani
Ngokungafani nemikhiqizo evela kubakhiqizi abadumile, ikhathalogu yeminikelo ye-Inno3D yesimanje ayihlukile kakhulu, futhi i-GeForce GTX 1660 ne-GTX 1660 Ti atholakala kuphela njengamamodeli e-Twin X2. Ngaphansi kwalolu hlobo, i-Inno3D ikhiphe ama-accelerator amaningana kuwo wonke ama-GPU e-Turing architecture - kuze kufike ku-GeForce RTX 2080 Ti. Ngayinye yazo iphawuleka ngentengo yayo ethengekayo endaweni yayo yemakethe futhi isebenza ngamafrikhwensi ewashi eliyisithenjwa. Ngokunjalo, imvamisa ye-GPU eyisisekelo ye-Inno3D GeForce GTX 1660 Twin X2 ingu-1530 MHz, futhi inani elilinganiselwe ngaphansi komthwalo ojwayelekile (Iwashi Lokukhuphula) lingu-1785 MHz. Kodwa-ke, i-NVIDIA ibukela phansi amandla amakhadi ayo evidiyo, ngoba ngisho nasemidlalweni efunwa kakhulu, amadivaysi ochungechunge lwe-GeForce 10, 16 no-20 ngokuvamile adlula ngaphezulu. Nokho, ngokuqinisekile sizothola lokhu esigabeni sokuhlola. Njengazo zonke izinhlobo ze-GeForce GTX 1660, ibhodi le-Inno3D liphethe i-6 GB ye-GDDR5 RAM, ephinde ibe nomkhawulokudonsa oyinkomba we-8 Gbps ngephinikhodi ngayinye.

Emakethe yaseRussia, i-NVIDIA ekuqaleni yayinentengo ye-GeForce GTX 1660 ngama-ruble angu-17, kodwa ngemva kwenyanga yokukhululwa komkhiqizo omusha, amanani entengo yokuguqulwa kwawo okuhlukahlukene asuka enanini elinconyiwe. Izinguqulo ze-"Premium" ze-GTX 990, ngokusho kwe-Yandex Market, zifinyelela kuma-ruble angu-1660, futhi imodeli "edume kakhulu" ingathengwa ngama-ruble angu-20 kuphela. - lena yi-Inno240D GeForce GTX 15 Twin X975. Kodwa asizange sikuthole kumapulatifomu okuhweba angaphandle, ngakho-ke abangenisi abazimele kuzodingeka bacabangele amanye amathuba okonga imali.
Naphezu kwesilinganiso sayo esihle kakhulu sentengo-kuya-kukusebenza, i-Inno3D GeForce GTX 1660 Twin X2 inezimbangi ezifanele esigabeni sekhadi lemifanekiso elingaphansi kwe-$250. I-AMD yamukele ukuqalwa kwemikhiqizo emisha “eluhlaza” ngokunciphisa amanani e-Radeon RX 580 kanye ne-Radeon RX 590. I-flagship yama-accelerator kuma-chips e-Polaris manje isiyatholakala ngentengo yama-ruble angu-16, kanye ne-Radeon RX 261 ekucushweni okune-580. I-GB ye-RAM - kusuka kuma-ruble ayi-8. Lawa magugu ahambisana kakhulu nendlela izimbangi ezisatshalaliswe ngayo ekubuyekezeni kwethu kokuqala kwe-GeForce GTX 12. Kodwa-ke, i-AMD ikuvumela ukuthi wehlise izindleko zokuthuthukisa ngisho nangokwengeziwe ngamamodeli we-Radeon RX 517 ngememori engu-1660 GB, izindleko zayo eziqalayo. ngama-RUB ayi-580.
Ngaphandle kokushibha kwe-Inno3D GeForce GTX 1660 Twin X2, ikhadi levidiyo lifake okuthile okubalulekile - okhiye bezinguqulo ezikhokhelwayo zamaphakheji okuhlola e-3DMark kanye ne-VRMark. Kodwa azikho ezinye izesekeli ebhokisini ngaphandle kwe-software disc.
Ukwakhiwa
Ingaphandle le-Inno3D GeForce GTX 1660 Twin X2 ayidingi incazelo enemininingwane. Ngokubukeka, ikhadi levidiyo lihluka kancane kwezinye izinguquko eziningi zesabelomali zochungechunge lwe-GeForce GTX 10 no-16. Ngenxa yobukhulu bayo obulinganiselwe, ungase ucabange ukuthi ilingana nobukhulu be-Mini-ITX form factor systems, kodwa cha - idivayisi iyinde ngo-1,96 cm kuno-17 cm odingekayo. Yebo, akukho ukukhanya kwe-LED noma okunye ukuhlobisa ongakukhetha. Ngisho nepuleti lokuvikela elingemuva kwePCB alikho.
Ingaphakathi le-Inno3D GeForce GTX 1660 Twin X2 lishaywa abalandeli ababili abanobubanzi obungu-72 mm. Ngenxa yokuthi umkhiqizi akazange alule i-casing yesistimu yokupholisa ngaphezu kobukhulu be-PCB, njengoba kuvame ukwenziwa ngamakhadi wevidiyo ahlangene, sasingasekho isikhala esanele sama-impellers abanzi. Ezingeni lokushisa eliyikristalu elingu-45 °C, uhlelo lokupholisa lusebenza ngendlela eyinqaba ye-semi-passive: abalandeli bahlezi bemile cishe ngaso sonke isikhathi, kodwa njalo ngemizuzwana embalwa baphila ukuze benze izinguquko ezimbalwa.
Ngenxa yokusebenzisa kwayo amandla aphansi (i-120 W ngokusho kwezinkomba zereferensi ye-GeForce GTX 1660), i-TU116 GPU ipholiswe ngempumelelo yi-heatsink ehlangene enomklamo olula. Kodwa-ke, onjiniyela be-Inno3D abazange balahle izindleko zamapayipi okushisa awugqinsi angu-4 mm axhumene ngqo nekristalu ye-GPU. I-GIGABYTE, ngokwesibonelo, ezinguqulweni zayo zesabelomali i-GeForce GTX 1660 kanye ne-GTX 1660 Ti eyenziwe nge-handset eyodwa.
Ibhodi lesifunda eliphrintiwe
Njengoba ama-chips e-TU116 kanye ne-TU106 eshintshashintsha ngokuya ngokusebenza ngokomzimba, izinketho eziningi zisuselwa ku-GeForce GTX 1660, 1660 Ti, kanye с Kunamabhodi esekethe aphrintiwe afanayo. Abakhiqizi bashintsha kuphela i-GPU ngokwayo, uhlobo nenombolo yama-memory chips, kanye nokucushwa kwesilawuli sikagesi. Uma sibheka izici zangaphandle, wonke amamodeli e-Inno3D Twin X2 afika ku-GeForce RTX 2070 nawo asekelwe ku-PCB efanayo. Kuyathakazelisa ukuthi inokumaka kwe-NVIDIA: kubonakala sengathi i-Inno3D ithenga amakristalu e-Turing kulolu chungechunge lwamadivayisi kanye namabhodi ezithenjwa.
I-PCB inamaphedi okuxhumana ezingxenye zezigaba eziyisithupha zokunikezwa kwamandla kagesi we-GPU kanye nezigaba ezimbili zokunikezwa kwamandla kagesi wama-RAM chips, kodwa ku-GeForce GTX 1660 kuphela isigaba ezine nesisodwa ezithengiswayo, ngokulandelana. Ukucushwa okunesizotha, kodwa njengoba i-GeForce GTX 1060 Founders Edition inenani lezigaba ezine, khona-ke imodeli encane ku-chip ye-TU116 kufanele ngabe yanele ezinhlanu. Ngenxa yobudlelwano bawo namakhadi evidiyo ochungechunge lwe-GeForce RTX, isilawuli sikagesi se-Inno3D GeForce GTX 1660 Twin X2 siqukethe ama-transistors asebenza ebaleni anomshayeli owakhelwe ngaphakathi (okuthiwa i-DrMOS, noma “izigaba zamandla” - izigaba zamandla). Uma kuqhathaniswa namapheya ahlukene omshayeli we-transistor, isisombululo esihlanganisiwe sinikeza ukusebenza kahle okwandisiwe futhi sivumela isilawuli se-PWM ukuthi silawule ngokunembile i-voltage ephumayo.
Amandla engeziwe anikezwa ekhadini levidiyo ngesixhumi esisodwa samaphini ayisishiyagalombili, futhi isethi yokuxhumana kwangaphandle iqukethe okuphumayo okuthathu kwe-DisplayPort kanye ne-HDMI eyodwa. Uma sibheka ukwakheka kwamaphedi othintana naye, ibhodi lesifunda eliphrintiwe eliphrintiwe likuvumela ukuthi ushintshe izixhumi ezimbili ze-DisplayPort ngesihloko se-DVI, esingalungela i-accelerator engabizi, kodwa i-Inno3D ayizange isebenzise leli thuba.
