I-NVIDIA isanda kukhipha ikhadi lemifanekiso yokudlala ye-GeForce GTX 1660 Ti esekelwe ku-TU116 GPU entsha, kodwa ukunyakaza kwe-Turing architecture kumadivayisi wesabelomali akukakapheli. Nge-GTX 1660 Ti, inkampani yashintsha i-GeForce GTX 1070 ngemodeli entsha nethengekayo esebenzisa amandla aphansi, kodwa i-GeForce GTX 1660 entsha ibhekene nomunye umsebenzi: ukuvala igebe kukhathalogi ye-NVIDIA esekhona phakathi kwe-GeForce GTX. 1060 kanye ne-GTX 1070 Ngekwindla edlule, i-Radeon RX 590 yazinza kuleli gebe, futhi i-Radeon RX 580, ngenxa yokwenziwa ngcono komshayeli nokushintshwa kwemidlalo ku-Direct3D 12, yaba okungenani enye indlela efanelekayo ku-GeForce GTX 1060. ngokukhululwa kwe-GTX 1660, ama-GPU "abomvu" anembangi enzima esigabeni esikhulu samakhadi wevidiyo wabathengi, ngoba umkhiqizo omusha ushibhile kune-Radeon RX 590 futhi unamandla aphezulu okusebenza.
Izici zobuchwepheshe, intengo
I-GeForce GTX 1660 isuselwe kuphrosesa yezithombe ze-TU116 enamayunithi ekhompyutha avaliwe kancane. Umehluko ekucushweni kwe-GPU phakathi kwe-GTX 1660 ne-GTX 1660 Ti wehlela kuma-multiprocessors amabili okusakaza (ama-SMs), ahlangene aqukethe ama-cores angu-128 32-bit CUDA kanye namamephu wokuthungwa angu-8. Ngakho-ke, ukuphuma kwe-GeForce GTX 1660 kuhlupheke kuphela u-8,3% ekusebenzeni kwamaphuzu antantayo kanye nokugcwaliswa kwe-texel ngaphandle kokulungisa isivinini sewashi le-GPU. Futhi ama-frequencies, ngendlela, akhule kuphela kumodeli encane: i-NVIDIA inyuse imvamisa yesisekelo ngo-30 MHz, kanye newashi le-Boost ngo-15 MHz.
Kodwa izinguquko ezicashile ezinjalo ngeke zanele ukuhlukanisa i-GeForce GTX 1660 ne-GTX 1660 Ti. Isici esiyinhloko esahlukanisa amamodeli amabili kwakuwuhlobo lwe-RAM. Ngenkathi ukuguqulwa kwe-Ti kufakwe ama-chips e-GDDR6 anomkhawulokudonsa we-12 Gbps ngephinikhodi, i-GeForce GTX 1660 ibuyele ezingeni le-GDDR5. Ngaphezu kwalokho, i-GTX 1660 ifakwe ama-chips anomkhawulokudonsa ongu-8 Gbit/s, okusho ukuthi ngokwengqikithi yomkhawulokudonsa wememori, ikhadi elisha levidiyo lihambisana ngokugcwele nezicaciso zokuqala ze-GeForce GTX 1060 ene-6 GB RAM, kanye izinguqulo zakamuva ze-GTX 1060 ene-RAM engu-9 Gbit/s ngisho nokudlula i-GTX 1660 inale pharamitha. Nokho, iphrosesa yehluzo ye-TU116, ngenxa yokucindezelwa kombala okuthuthukisiwe, isebenza nge-RAM ngokuphumelelayo.
Njengoba isivinini sewashi noma ukucushwa kwe-GPU kwe-GeForce GTX 1660 ne-GTX 1660 Ti kuhluke kakhulu, futhi imodeli encane ibuye ithwale ama-RAM chips asebenzisa amandla aphezulu (uma kuqhathaniswa ne-GDDR6), ama-accelerator amabili amancane omndeni wakwaTuring abonakalisiwe. ngesigcinimandla esifanayo - 120 W.
Sesixoxile kakade ngezinye izici ze-chip ye-TU116 uma siqhathanisa nabameleli abagcwele bomndeni wakwaTuring (TU106, TU104 kanye ne-TU102) ekubuyekezweni kwe-GeForce GTX 1660 Ti, kodwa kufanelekile ukugxila ezicini ezimbalwa ezibalulekile ezenza I-TU116 efana nama-analogue ayo amadala noma, ngokuphambene, dweba phakathi kwawo umngcele ongenakunqotshwa. Sekukonke, i-TU116 ihlanganisa zonke izinto eziqanjiwe i-NVIDIA ezisebenzisayo ekwakhiweni kwe-Turing, ngaphandle kwama-cores enza i-Ray Tracing kanye nama-tensor cores enza izibalo ze-FMA (Fused-Multiply Add) kumatrices wangempela one-half-nemba (FP16). ). Okwakamuva kusetshenziswa ikakhulukazi emisebenzini yokufunda ngomshini, lapho i-GPU idlulisa idatha kunethiwekhi ye-neural eyakhiwe ngaphambilini endaweni noma epulazini elikude. Ngakho-ke, i-GeForce GTX 1660 ne-GTX 1660 Ti ngesikhathi esisodwa zalahlekelwa ukuhambisana nakho kokubili i-DXR (isandiso se-Direct3D 12 sokulandelela i-ray) kanye nobuchwepheshe be-DLSS, obuvumela i-GPU ukuthi inikeze ngesinqumo esincishisiwe ngokukalwa kohlaka okulandelayo kusetshenziswa inethiwekhi ye-neural.
Esikhundleni samayunithi we-tensor, i-NVIDIA ihlomise i-TU116 ngohlu oluhlukile lwe-16-bit CUDA cores - ayisheshi ngokwanele ukusebenzisa i-DLSS ngempumelelo, kodwa sekuvele kunemidlalo esebenzisa ukusebenza okunembayo okuyingxenye ekubalweni kwe-shader (isibonelo, i-Wolfenstein II : I-New Colossus), ngenxa yokuthi ukusebenza kwama-GPU afanelekile (okwamanje ama-Vega nama-Turing chips) kukhuphuka kakhulu. Uma kungenjalo, futhi, i-TU116 ihluka kuma-chips amadala omndeni wayo kuphela ngendlela yobuningi, inakho konke ukulungiselelwa kwamapayipi okukhona ekwakhiweni kwe-Turing, futhi isekela imisebenzi yokunikezela ngokuphathelene njenge-VRS (I-Variable Rate Shading).
