NVIDIA ichangobva kuburitsa iyo GeForce GTX 1660 Ti yemitambo yemakadhi kadhi yakavakirwa paiyo TU116 GPU itsva, asi kufamba kweiyo Turing dhizaini kuenda kumidziyo yebhajeti haisati yapera. NeGTX 1660 Ti, kambani yakatsiva iyo GeForce GTX 1070 nemhando nyowani uye inodhura ine yakaderera mashandisiro emagetsi, asi iyo itsva GeForce GTX 1660 inotarisana nerimwe basa: kuvhara mukaha muNVIDIA kabhuku ichiripo pakati peGeForce GTX. 1060 uye GTX 1070 Kudonha kwekupedzisira, iyo Radeon RX 590 yakagara mune gaka iri, uye iyo Radeon RX 580, semhedzisiro yekufambisa kwemutyairi uye shanduko yemitambo kuenda kuDirect3D 12, yakava imwe nzira yakakodzera kuGeForce GTX 1060. nekuburitswa kweGTX 1660, maGPU "dzvuku" ane mukwikwidzi akakomba muchikamu chikuru chemakadhi evhidhiyo evatengi, nekuti chigadzirwa chitsva zvese zvakachipa kupfuura Radeon RX 590 uye ine yepamusoro yekuita.
Unhu hwehunyanzvi, mutengo
Iyo GeForce GTX 1660 yakavakirwa paTU116 graphics processor ine chikamu deactivated computing units. Musiyano mukugadziriswa 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 mamepu. Nekudaro, iyo GeForce GTX 1660 throughput yakangotambura chete 8,3% mukuyangarara nzvimbo mashandiro uye texel fillrate pasina kugadzirisa kweGPU wachi kumhanya. Uye mafambiro, nenzira, akawedzera chete mudiki modhi: NVIDIA yakawedzera base frequency ne30 MHz, uye Boost Clock ne15 MHz.
Asi shanduko dzakajeka dzakadaro dzaisazokwana kusiyanisa GeForce GTX 1660 uye GTX 1660 Ti. Chinhu chikuru chekuparadzanisa mhando mbiri yaive mhando ye RAM. Nepo iyo Ti gadziriso yakashongedzerwa neGDDR6 machipi ane bandwidth yegumi nemaviri Gbps papini, iyo GeForce GTX 12 yakadzokera kune iyo GDDR1660 standard. Uyezve, iyo GTX 5 ine machipisi ane bandwidth ye1660 Gbit/s, zvinoreva kuti maererano nehuwandu hwekuyeuka bandwidth, kadhi nyowani yevhidhiyo inoenderana zvizere nekutanga kutaurwa kweGeForce GTX 8 ine 1060 GB RAM, uye iyo shanduro dzekupedzisira dzeGTX 6 ine 1060 Gbit/s RAM inotopfuura iyo GTX 9 ine iyi parameter. Zvisinei, iyo TU1660 graphics processor, nekuda kwekuvandudzwa kwemavara, inoshanda ne RAM zvakanyanya.
Sezvo isingamhanyire wachi kana iyo GPU kumisikidzwa yeGeForce GTX 1660 uye GTX 1660 Ti zvakasiyana zvakanyanya, uye mudiki modhi zvakare inotakura RAM machipisi ane yakakwira simba rekushandisa (ichienzaniswa neGDDR6), maviri madiki accelerator emhuri yeTuring anozivikanwa. nesimba rimwe chete rekuchengetedza - 120 W .
Takatokurukura mamwe maitiro eTU116 chip tichienzanisa nevamiriri vakazara veTuring mhuri (TU106, TU104 uye TU102) mukuongorora kweGeForce GTX 1660 Ti, asi zvakakodzera kutarisa pane akati wandei akakosha maficha anoita TU116 yakafanana neyekare analogues kana, ukuwo, dhirowa pakati pavo muganho usingakundike. Pakazara, iyo TU116 inoratidzira zvese zvitsva izvo NVIDIA yakaita muTuring architecture, kunze kwemacores anoita Ray Tracing uye tensor cores anoita FMA (Fused-Multiply Wedzera) kuverenga pahafu-chaiyo chaiyo matrices (FP16). ) Iwo ekupedzisira anoshandiswa kunyanya mumabasa ekudzidza muchina, apo GPU inopfuudza data kuburikidza neural network pre-yakaumbwa munharaunda kana papurazi riri kure. Nekudaro, iyo GeForce GTX 1660 uye GTX 1660 Ti panguva imwe chete yakarasika kuenderana neese DXR (Direct3D 12 yekuwedzera yeray tracing) uye DLSS tekinoroji, iyo inobvumira iyo GPU kupa pane yakaderedzwa resolution neinotevera furemu kuyera uchishandisa neural network.
Panzvimbo pema tensor units, NVIDIA yakashongedza iyo TU116 neyakasiyana-siyana 16-bit CUDA cores - haina kukurumidza kumhanya DLSS zvinobudirira, asi pane yatova mitambo inoshandisa hafu-chaiyo mashandiro mu shader kuverenga (semuenzaniso, Wolfenstein II. : Iyo New Colossus), nekuda kwekuti kuita kweakakodzera maGPU (ikozvino Vega uye Turing chips) kunowedzera zvakanyanya. Zvikasadaro, zvakare, iyo TU116 inosiyana kubva kune ekare machipisi emhuri yayo chete nenzira yehuwandu, ine ese mapipeline optimizations ari mukati meiyo Turing architecture, uye inotsigira proprietary kupa mabasa akadai seVRS (Variable Rate Shading).

GIGABYTE GeForce GTX 1660 OC: PCB
Kubva paPCB yakashandiswa muGeForce GTX 1660, GIGABYTE yakatogadzira mimwe michina yakawanda, kubva kuGeForce GTX 1660 Ti kusvika kuGeForce RTX 2070. Iyi mhando yemhando inosanganisira maGPU akasiyana-siyana (TU116, TU106) nemhando mbiri dze RAM. machipisi (GDDR5 neGDDR6) anowirirana nemagetsi, uye zvimiro zvidiki zvePCB zvakaita kuti zvikwanise kugadzira ese maturusi ezviyero zvakajairwa uye compact vhidhiyo makadhi eMini ITX fomu chinhu.
Iyi PCB inogona kugamuchira zvikamu zvezvikamu zvisere zvemagetsi regulator, asi mashandisirwo emagetsi emidziyo yakavakirwa paTU116 uye TU106 kubva pa120 kusvika 175 W (maererano nereferenzi), saka iyo yakaderera-yekupedzisira accelerator inogutsikana nenhanhatu-chikamu. VRM: zvikamu zvina zvinoshandira GPU uye maviri - microcircuits random access memory. Nekuda kwehukama hwayo nemhando dzekare dzemhuri yeTuring, chigadzirwa chitsva chakashongedzerwa nemunda-effect transistors ane akabatanidzwa mutyairi (anonzi DrMOS kana "matanho emagetsi" - nhanho dzemagetsi), izvo zvinopa kugona kwakanyanya uye kubvumira VRM PWM controller kunyatsorekodha voltage pakudonhedza kwema transistors.
Kunyangwe iyo TU116's display controller iri DVI inoenderana, GIGABYTE yakasarudza matatu eDisplayPort majoini uye imwe HDMI inobuda.
