Chifukwa chakusintha kwaposachedwa kwa oyendetsa, makadi ojambula a GeForce 10 ndi 16 aphunzira kutsatira ray m'masewera omwe athandizidwa ndi DXR. pa ΠΈ (ndi mitundu ina iliyonse ya NVIDIA, kupatula GeForce RTX ndi ma accelerator akale pa tchipisi ta Pascal) ntchitoyi m'malo mwake imagwira ntchito pachiwonetsero m'malo mokhala ndi phindu lililonse. Koma ngakhale kufufuza kwa ray kwa nthawi yeniyeni sikungatheke kwa GeForce GTX 1660, izi sizimasokoneza ubwino wina wa membala wamng'ono kwambiri wa banja la Turing. GeForce GTX 1060 yataya chidwi chake chakale, ndipo mphamvu pakati pa makadi ojambula apakati pamtengo wasintha mokomera Radeon RX 580 ndi , komabe, zatsopano pa chipangizo cha TU116 nthawi yomweyo zidabweza NVIDIA paudindo wa utsogoleri.
Powunika makhadi apakanema ochita bwino kwambiri, chidwi cha atolankhani nthawi zambiri chimangoyang'ana pamitundu yamtengo wapatali yokhala ndi zida zamphamvu zozizirira, mapangidwe ochititsa chidwi komanso zina zambiri. Koma pankhani yachitsulo chochuluka, ndikofunika kwambiri kuti muphunzire malo otsika a mndandanda wamtengo wapatali. Kugwiritsa ntchito mphamvu pang'ono kwa GeForce GTX 1660 kumakupatsani mwayi wochepetsera mawaya a makadi a kanema, pomwe mukusunga malire achitetezo ochulukirapo. Tiyeni tiphunzire momwe kuphweka kumasungira mphamvu zowonjezera pogwiritsa ntchito chitsanzo cha Inno3D GeForce GTX 1660 Twin X2.
Makhalidwe aukadaulo, kuchuluka kwa kutumiza, mitengo
Mosiyana ndi zopangidwa kuchokera kwa opanga otchuka kwambiri, kabukhu la zopereka zamakono za Inno3D sizosiyana kwambiri, ndipo GeForce GTX 1660 ndi GTX 1660 Ti imapezeka ngati mitundu ya Twin X2. Pansi pa mtundu uwu, Inno3D yatulutsa ma accelerator angapo pama GPU onse a Turing - mpaka GeForce RTX 2080 Ti. Iliyonse yaiwo ndi yodziwika chifukwa cha mtengo wake wotsika mtengo pamsika wake ndipo imagwira ntchito pafupipafupi. Chifukwa chake, ma frequency a GPU oyambira a Inno3D GeForce GTX 1660 Twin X2 ndi 1530 MHz, ndipo mtengo woyerekeza (Boost Clock) ndi 1785 MHz. Komabe, NVIDIA imapeputsa kuthekera kwa makhadi ake apakanema, chifukwa ngakhale m'masewera ovuta kwambiri, zida za GeForce 10, 16 ndi 20 nthawi zambiri zimapitilira. Komabe, tidzapeza izi poyesa. Monga mitundu yonse ya GeForce GTX 1660, bolodi ya Inno3D imanyamula 6 GB ya GDDR5 RAM, yomwe ilinso ndi bandwidth ya 8 Gbps pa pini iliyonse.

Pamsika wa ku Russia, NVIDIA poyamba inagula GeForce GTX 1660 pa 17 rubles, koma mwezi umodzi pambuyo pa kutulutsidwa kwa mankhwala atsopano, mitengo ya zosintha zake zosiyanasiyana inachoka pamtengo wovomerezeka. Matembenuzidwe a "Premium" a GTX 990, malinga ndi Yandex Market, amafika ma ruble 1660, ndipo chitsanzo "chotchuka" chingagulidwe pa ma ruble 20 okha. - iyi ndi Inno240D GeForce GTX 15 Twin X975. Koma sitinazipeze pa nsanja zamalonda zakunja, kotero otsatsa achinsinsi ayenera kuganizira mwayi wina wosunga ndalama.
Ngakhale kuti mtengo wake ndi wabwino kwambiri pakuchita bwino, Inno3D GeForce GTX 1660 Twin X2 ili ndi opikisana nawo oyenera m'gulu lamakhadi azithunzi a $ 250. AMD idalonjera kuyambika kwa zinthu zatsopano "zobiriwira" pochepetsa mitengo ya Radeon RX 580 ndi Radeon RX 590. Mlandu wa accelerators pa tchipisi ta Polaris tsopano ukupezeka pamtengo wa 16 rubles, ndi Radeon RX 261 mu kasinthidwe ndi 580. GB ya RAM - kuchokera ku ma ruble 8. Izi zimagwirizana kwambiri ndi momwe opikisanawo adagawira mu ndemanga yathu yoyamba ya GeForce GTX 12. Komabe, AMD imakupatsani mwayi wochepetsera ndalama zowonjezera kudzera mu zitsanzo za Radeon RX 517 ndi 1660 GB ya kukumbukira, mtengo wake umayamba. ndi ma ruble 580.
Ngakhale kutsika mtengo kwa Inno3D GeForce GTX 1660 Twin X2, khadi la kanema linaphatikizapo chinthu chamtengo wapatali - makiyi amitundu yolipira ya 3DMark ndi VRMark test phukusi. Koma palibe zowonjezera zina m'bokosi kupatula pulogalamu ya pulogalamu.
Ntchito yomanga
Kunja kwa Inno3D GeForce GTX 1660 Twin X2 sikufuna kufotokozera mwatsatanetsatane. Maonekedwe, khadi la kanema limasiyana pang'ono ndi zosintha zina zambiri za GeForce GTX 10th ndi 16th series. Chifukwa cha kukula kwake kocheperako, mungaganize kuti ikugwirizana ndi miyeso ya Mini-ITX mawonekedwe a machitidwe, koma ayi - chipangizocho ndi 1,96 cm yaitali kuposa masentimita 17. Inde, palibe kuwala kwa LED kapena zokongoletsera zina. Ngakhale mbale yoteteza kumbuyo kwa PCB ikusowa.
Mkati mwa Inno3D GeForce GTX 1660 Twin X2 amawomberedwa ndi mafani awiri okhala ndi mainchesi 72 mm. Chifukwa chakuti wopanga sanali kutambasula kuzirala dongosolo casing kupitirira miyeso PCB, monga nthawi zambiri amachita ndi yaying'ono mavidiyo makadi, panalibenso malo okwanira kwa impellers ambiri. Pa kutentha kwa kristalo kwa 45 Β° C, makina ozizirira amagwira ntchito modabwitsa: mafaniwo amakhala osasunthika nthawi zonse, koma masekondi angapo aliwonse amakhala ndi moyo kuti apange masinthidwe angapo.
Chifukwa chakugwiritsa ntchito mphamvu zochepa (120 W molingana ndi mafotokozedwe a GeForce GTX 1660), TU116 GPU imakhazikika bwino ndi heatsink yaying'ono yokhala ndi kapangidwe kosavuta. Komabe, akatswiri a Inno3D sanawononge ndalama pa mapaipi atatu otentha a 4 mm omwe amalumikizana mwachindunji ndi kristalo wa GPU. GIGABYTE, mwachitsanzo, m'matembenuzidwe ake a bajeti GeForce GTX 1660 ndi GTX 1660 Ti adachita ndi foni imodzi.
bolodi losindikizidwa
Popeza tchipisi ta TU116 ndi TU106 zimasinthasintha malinga ndi mawonekedwe akuthupi, zosankha zambiri zimachokera ku GeForce GTX 1660, 1660 Ti, ndi Ρ Palinso mapepala osindikizira ofanana. Opanga amangosintha GPU yokha, mtundu ndi kuchuluka kwa tchipisi tokumbukira, komanso masinthidwe amagetsi owongolera. Tikayang'ana zakunja, mitundu yonse ya Inno3D Twin X2 mpaka GeForce RTX 2070 imakhazikitsidwanso pa PCB yomweyo. Ndizosangalatsa kuti ili ndi cholembera cha NVIDIA: zikuwoneka kuti Inno3D ikugula makhiristo a Turing pazida izi limodzi ndi ma boardboard.
PCB ili ndi zolumikizirana za magawo asanu ndi limodzi amagetsi a GPU ndi magawo awiri amagetsi a tchipisi ta RAM, koma mu GeForce GTX 1660 magawo anayi okha ndi gawo limodzi ndi omwe amagulitsidwa, motsatana. Ndikosavuta, koma popeza GeForce GTX 1060 Founders Edition inali ndi magawo anayi, ndiye kuti chitsanzo chaching'ono pa chipangizo cha TU116 chiyenera kukhala chokwanira ndi zisanu. Chifukwa cha ubale wake ndi makhadi a kanema a GeForce RTX, Inno3D GeForce GTX 1660 Twin X2 voltage regulator ili ndi ma transistors oyendetsa ntchito omwe ali ndi dalaivala womangidwa (omwe amatchedwa DrMOS, kapena "magawo amagetsi" - magawo amagetsi). Poyerekeza ndi awiriawiri oyendetsa-transistor, yankho lophatikizika limapereka mwayi wowonjezereka ndipo limalola wolamulira wa PWM kuwongolera bwino mphamvu yamagetsi.
Mphamvu zowonjezera zimaperekedwa ku khadi la kanema kudzera pa cholumikizira chimodzi cha pini zisanu ndi zitatu, ndipo mawonekedwe akunja ali ndi zotuluka zitatu za DisplayPort ndi HDMI imodzi. Potengera masanjidwe a mapepala olumikizirana, bolodi losindikizidwa losindikizidwa limakupatsani mwayi kuti musinthe zolumikizira ziwiri za DisplayPort ndi mutu wa DVI, womwe ungakhale woyenera pa accelerator yotsika mtengo, koma Inno3D sanagwiritse ntchito mwayiwu.
