Enkosi kuhlaziyo lwamva nje lomqhubi, amakhadi egraphic GeForce 10 kunye ne-16 afunde ukwenza umkhondo we-ray kwimidlalo enikwe amandla yi-DXR. phezu ΠΈ (kunye nazo naziphi na ezinye iimodeli ze-NVIDIA, ngaphandle kwe-GeForce RTX kunye ne-accelerators endala kwiitshiphusi zePascal) lo msebenzi endaweni yoko usebenza kwimowudi yedemo kunokuba ube nalo naliphi na ixabiso elisebenzayo. Kodwa nokuba umkhondo we-ray wexesha lokwenyani awukho amandla eGeForce GTX 1660, oku akuphazamisi kwezinye iingenelo zelona lungu lincinci losapho lweTuring. I-GeForce GTX 1060 iphulukene nesibheno sayo sangaphambili, kwaye ibhalansi yamandla phakathi kwamakhadi emizobo yexabiso eliphakathi itshintshile ithanda iRadeon RX 580 kunye. , nangona kunjalo, iimveliso ezintsha kwi-chip ye-TU116 zibuyisele ngoko nangoko i-NVIDIA kwindawo yobunkokeli.
Kuphononongo lwamakhadi evidiyo asebenza kakhulu, ingqalelo yoshicilelo idla ngokujoliswa kwiimodeli ezibizayo ezineenkqubo ezinamandla zokupholisa, uyilo olunomtsalane kunye nezinto ezininzi ezongezelelweyo. Kodwa xa kuziwa kwintsimbi yobuninzi, kubaluleke kakhulu ukufunda izikhundla ezisezantsi zoluhlu lwamaxabiso. Ukusetyenziswa kwamandla aphantsi kweGeForce GTX 1660 kukuvumela ukuba wenze lula kakhulu i-wiring yekhadi levidiyo, ngelixa kwangaxeshanye ugcina umda omkhulu wokhuseleko lokugqithisa. Masifunde indlela yokwenza lula igcina amandla okugqithisa usebenzisa umzekelo we-Inno3D GeForce GTX 1660 Twin X2.
Iimpawu zobugcisa, ububanzi bokuhanjiswa, amaxabiso
Ngokungafaniyo neemveliso ezivela kubavelisi abadumileyo, ikhathalogu yeminikelo ye-Inno3D yanamhlanje ayihlukanga kakhulu, kwaye iGeForce GTX 1660 kunye neGTX 1660 Ti zifumaneka kuphela njengeemodeli zeTwin X2. Ngaphantsi kolu phawu, i-Inno3D ikhuphe ii-accelerators ezininzi kuzo zonke ii-GPU zoyilo lweTuring-ukuya kuthi ga kwiGeForce RTX 2080 Ti. Nganye kuzo iphawuleka ngexabiso layo elifikelelekayo kwi-niche yayo yentengiso kwaye isebenza ngokungqongqo ireferensi yewotshi. Ngokuhambelanayo, isiseko se-GPU frequency ye-Inno3D GeForce GTX 1660 Twin X2 yi-1530 MHz, kwaye ixabiso eliqikelelweyo phantsi komthwalo oqhelekileyo (i-Boost Clock) yi-1785 MHz. Nangona kunjalo, i-NVIDIA ijongela phantsi amandla ekhadi layo levidiyo, kuba nakwimidlalo efuna kakhulu, izixhobo ze-GeForce 10, 16 kunye ne-20 zihlala zigqithise ngaphezulu. Nangona kunjalo, ngokuqinisekileyo siya kukufumanisa oku kwinqanaba lovavanyo. Njengazo zonke iintlobo zeGeForce GTX 1660, ibhodi ye-Inno3D ithwala i-6 GB ye-GDDR5 RAM, ephinda ibe ne-bandwidth ye-reference ye-8 Gbps ngephini yebhasi.

Kwimarike yaseRashiya, i-NVIDIA yaqala ixabiso le-GeForce GTX 1660 kwi-ruble ye-17, kodwa emva kwenyanga emva kokukhululwa kwemveliso entsha, amaxabiso eenguqu zayo ezahlukeneyo asuka kwixabiso elicetyiswayo. Iinguqulelo ze-"Premium" ze-GTX 990, ngokwe-Yandex Market, zifikelela kuma-ruble angama-1660, kwaye imodeli "ethandwayo" ingathengwa kuphela kwii-ruble ze-20. - le yi-Inno240D GeForce GTX 15 Twin X975. Kodwa asizange siyifumane kwiiplatifti zokurhweba kwamanye amazwe, ngoko ke abathumeli babucala baya kufuneka baqwalasele amanye amathuba okugcina imali.
Ngaphandle komlinganiselo ogqwesileyo wexabiso-kwindlela yokusebenza, i-Inno3D GeForce GTX 1660 Twin X2 ineembangi ezifanelekileyo kuluhlu lwamakhadi emizobo engaphantsi kwe-$250. I-AMD ibulise ekuqaleni kweemveliso ezintsha "eziluhlaza" ngokunciphisa amaxabiso eRadeon RX 580 kunye neRadeon RX 590. I-flagship ye-accelerator kwi-chips ye-Polaris ngoku ifumaneka ngexabiso le-ruble ye-16, kunye ne-Radeon RX 261 kwi-configuration kunye ne-580. I-GB ye-RAM - ukusuka kwi-ruble ye-8. La maxabiso ahambelana kakhulu nendlela abakhuphisana abasasazwa ngayo kuphononongo lwethu lokuqala lweGeForce GTX 12. Nangona kunjalo, i-AMD ikuvumela ukuba unciphise iindleko zokuphucula ngakumbi ngeemodeli zeRadeon RX 517 kunye ne-1660 GB yememori, ixabiso eliqalayo. kwi-RUB 580.
Ngaphandle kokungabizi kakhulu kwe-Inno3D GeForce GTX 1660 Twin X2, ikhadi levidiyo libandakanya into exabisekileyo-izitshixo kwiinguqulelo ezihlawulweyo ze-3DMark kunye ne-VRMark iiphakheji zovavanyo. Kodwa azikho ezinye izixhobo kwibhokisi ngaphandle kwediski yesoftware.
Ukwakhiwa
Umphandle we-Inno3D GeForce GTX 1660 Twin X2 ayifuni nkcazelo eneenkcukacha. Ngokwembonakalo, ikhadi levidiyo lihluke kancinane kwezinye ezininzi iinguqulelo zebhajethi yeGeForce GTX 10 kunye ne-16th series. Ngenxa yobukhulu bayo obuthobekileyo, unokucinga ukuba ihambelana nemilinganiselo ye-Mini-ITX ye-form factor systems, kodwa akukho - isixhobo si-1,96 cm ubude kune-17 cm efunekayo. Nditsho nepleyiti ekhuselayo ngasemva kwePCB ilahlekile.
Ngaphakathi kwe-Inno3D GeForce GTX 1660 Twin X2 ivuthelwa ngabalandeli ababini kunye nobubanzi be-72 mm. Ngenxa yokuba umenzi akazange asolule inkqubo yokupholisa i-casing ngaphaya kwemilinganiselo ye-PCB, njengoko kusenziwa rhoqo ngamakhadi evidiyo ahlangeneyo, kwakungasekho sithuba saneleyo se-impellers ebanzi. Kwiqondo lobushushu lekristale le-45 Β°C, inkqubo yokupholisa isebenza ngendlela engaqhelekanga ye-semi-passive: abalandeli bahlala bemile phantse ngalo lonke ixesha, kodwa yonke imizuzwana embalwa beza ebomini ukwenza iinguqulelo ezininzi.
Ndiyabulela ekusebenziseni amandla aphantsi (i-120 W ngokwe-GeForce GTX 1660 yereferensi), i-TU116 GPU ipholile ngokufanelekileyo yi-heatsink edibeneyo kunye noyilo olulula. Nangona kunjalo, iinjineli ze-Inno3D azigcinanga ndleko kwimibhobho yobushushu obuyi-4 mm obukhulu obunxibelelana ngokuthe ngqo nekristale yeGPU. I-GIGABYTE, umzekelo, kwiinguqulelo zayo zebhajethi i-GeForce GTX 1660 kunye ne-GTX 1660 Ti eyenziwe nge-handset enye.
Ibhodi yesekethe eprintiweyo
Ekubeni i-TU116 kunye ne-TU106 chips zitshintshiselana ngokumalunga nojongano lomzimba, ezininzi iinketho zisekelwe kwi-GeForce GTX 1660, 1660 Ti, kunye. Ρ Kukho iibhodi zesekethe eziprintiweyo ezifanayo. Abavelisi batshintsha kuphela i-GPU ngokwayo, uhlobo kunye nenani leememori zememori, kunye nokucwangciswa kwe-voltage regulator. Ukujonga ngeempawu zangaphandle, zonke iimodeli ze-Inno3D Twin X2 ukuya kuthi ga kwi-GeForce RTX 2070 nazo zisekwe kwi-PCB efanayo. Kunomdla wokuba ithwele uphawu lwe-NVIDIA: kubonakala ngathi i-Inno3D ithenga iikristale zeTuring kolu luhlu lwezixhobo kunye neebhodi zesalathiso.
I-PCB ineepads zoqhagamshelwano zamacandelo ezigaba ezithandathu zobonelelo lwamandla e-GPU kunye nezigaba ezibini zobonelelo lwamandla kwiichips ze-RAM, kodwa kwi-GeForce GTX 1660 kuphela ezine kunye nesigaba esinye esithengiswayo, ngokulandelanayo. Luqwalaselo oluthobekileyo, kodwa ekubeni iGeForce GTX 1060 Founders Edition inezigaba ezine zizonke, ngoko imodeli encinci kwi-chip ye-TU116 kufuneka yanele ezintlanu. Ngenxa yobudlelwane bayo kunye namakhadi evidiyo e-GeForce RTX, i-Inno3D GeForce GTX 1660 Twin X2 i-voltage regulator iqulethe ii-transistors ze-field-effect kunye nomqhubi owakhelwe ngaphakathi (obizwa ngokuba yi-DrMOS, okanye "izigaba zamandla" - izigaba zamandla). Xa kuthelekiswa ne-discrete driver-transistor pairs, isisombululo esihlanganisiweyo sibonelela ngokusebenza kakuhle kwaye sivumela umlawuli we-PWM ukuba alawule ngokuchanekileyo i-voltage ephumayo.
Amandla ongezelelweyo anikezelwa kwikhadi levidiyo ngekhonkco elilodwa lesibhozo, kwaye isethi ye-interfaces yangaphandle iqukethe iziphumo ezintathu ze-DisplayPort kunye ne-HDMI enye. Ngokujonga ukucwangciswa kweepadi zoqhagamshelwano, ibhodi yesekethe eprintiweyo yereferensi ikuvumela ukuba utshintshe iziqhagamshelo ezimbini zeDisplayPort kunye nentloko ye-DVI, eya kufaneleka kakhulu kwi-accelerator engabizi, kodwa i-Inno3D ayizange isebenzise eli thuba.
