NVIDIA ichangobva kuburitsa iyo GeForce GTX 1660 Ti yemitambo yemifananidzo kadhi yakavakirwa paiyo TU116 GPU itsva, asi iyo Turing yekuvaka yekusundira mumidziyo yebhajeti haisati yapera. NeGTX 1660 Ti, NVIDIA yakatsiva iyo GeForce GTX 1070 neiyo nyowani, inodhura modhi ine yakaderera simba rekushandisa. Nekudaro, iyo itsva GeForce GTX 1660 inotarisana nedambudziko rakasiyana: kuzadza gap riri mukatalogi yeNVIDIA ichiripo pakati peGeForce GTX 1060 neGTX 1070. Kudonha kwekupedzisira, Radeon RX 590 yakapinda mugedhi iri, uye Radeon RX 580, nekuda kwekugadzirisa mutyairi uye kuchinjika kwe3D kwakanyanya, Direction ye12D mitambo. yakakodzera imwe nzira yeGeForce GTX 1060. Asi nekuburitswa kweGTX 1660, maGPU "dzvuku" ane mukwikwidzi akakomba muchikamu chemakadhi emifananidzo yevatengi, sezvo kadhi idzva rakachipa kupfuura Radeon RX 590 uye rinopa mukana wepamusoro wekuita.
Unhu hwehunyanzvi, mutengo
Iyo GeForce GTX 1660 yakavakirwa paTU116 GPU ine chikamu chakaremara compute units. Musiyano mukumisikidzwa kweGPU pakati peGTX 1660 neGTX 1660 Ti unouya pasi kune maviri ekutepfenyura multiprocessors (SMs), ayo pamwe chete ane 128 32-bit CUDA cores uye 8 mamepu ekugadzira mepu. Naizvozvo, iyo GeForce GTX 1660's throughput yakatambura ne8,3% chete mukuyangarara-point mashandiro uye texel kuzadza mwero, isina kugadziriswa kweGPU wachi kumhanya. Sezvineiwo, mafambiro emudiki modhi akawedzera: NVIDIA yakawedzera base wachi ne30 MHz uye Boost Clock ne15 MHz.
Asi shanduko dzakajeka dzakadai dzingadai dzisina kukwana kusiyanisa GeForce GTX 1660 kubva kuGTX 1660 Ti. Musiyano mukuru pakati pemhando mbiri imhando ye RAM. Nepo iyo Ti vhezheni yakashongedzerwa neGDDR6 machipi ane gumi nemaviri Gbps yebandwidth papini, iyo GeForce GTX 12 yadzokera kune iyo GDDR1660 standard. Uyezve, iyo GTX 5 ine machipisi ane 1660 Gbps yebandwidth, zvichireva kuti maererano nehuwandu hwekurangarira bandwidth, kadhi nyowani yemifananidzo inoenderana zvizere nekumisikidzwa kweGeForce GTX 8 ine 1060 GB ye RAM, uye gare gare shanduro dzeGTX 6 ine 1060 Gbps RAM inotopfuura iyo GTX 9. Nekudaro, iyo TU1660 GPU, nekuda kwekuvandudzwa kwemavara kudzvanya, inoshanda ne RAM zvakanyanya.
Sezvo isingamhanyire wachi kana iyo GPU kumisikidzwa yeGeForce GTX 1660 uye GTX 1660 Ti yakasiyana zvakanyanya, uye mudiki modhi zvakare inotakura RAM machipisi ane yakakwira simba rekushandisa (ichienzaniswa neGDDR6), iwo maviri madiki accelerators emhuri yeTuring anoratidzirwa neiyo simba rekuchengetedza - 120 W.
Isu takatokurukura mamwe maitiro eTU116 chip tichienzanisa nevamiriri vakazara vemhuri yeTuring (TU106, TU104, uye TU102) muongororo yedu yeGeForce GTX 1660 Ti, asi zvakakodzera kuburitsa akati wandei akakosha maficha ayo anogona kugovera iyo TU116 pamwe neayo epamusoro-magumo evamwe kana, pakati peiyo isingagoneki. Pakazere, iyo TU116 inoratidzira ese magadzirirwo akaitwa neNVIDIA muTuring architecture, kunze kweiyo Ray Tracing cores uye Tensor Cores, inobata FMA (Fused-Multiply Wedzera) kuverenga pahafu-chaiyo chaiyo-nhamba matrices (FP16). Iwo ekupedzisira anonyanya kushandiswa mumichina yekudzidza mabasa, apo iyo GPU inomhanyisa data kuburikidza neural network pre-yakavakwa munharaunda kana papurazi riri kure. Nekudaro, iyo GeForce GTX 1660 neGTX 1660 Ti panguva imwe chete yakarasika kuenderana neese DXR (yeDirect3D 12 yekuwedzera yekutsvagisa ray) uye DLSS tekinoroji, iyo inobvumira iyo GPU kupa pane yakaderedzwa resolution uye yosimudza furemu uchishandisa neural network.
Panzvimbo ye tensor units, NVIDIA yakashongedza iyo TU116 neyakasiyana rondedzero yegumi nematanhatu-bit CUDA cores. Izvi hazvina kukurumidza zvakakwana kumhanya DLSS zvinobudirira, asi kune yatova mitambo inoshandisa hafu-chaiyo shader mashandiro (semuenzaniso, Wolfenstein II: The New Colossus), iyo inovandudza zvakanyanya mashandiro eGPU anowirirana (ikozvino Vega uye Turing GPUs). Zvikasadaro, iyo TU16 inosiyana kubva kune vanin'ina vayo vakuru chete muhuwandu, ichizvikudza ese pombi optimizations inoenderana neiyo Turing architecture uye inotsigira proprietary kupa maficha akadai seVRS (Variable Rate Shading).
