Waad ku mahadsan tahay cusbooneysiinta darawalka ee dhowaan, GeForce 10 iyo 16 kaararka garaafyada taxanaha ah waxay barteen inay ku sameeyaan raadinta raajo ciyaaraha karti u leh DXR. on ΠΈ (iyo nooc kasta oo kale oo NVIDIA ah, marka laga reebo GeForce RTX iyo dardargeliyayaasha da'da weyn ee Pascal chips) shaqadani waxay ku shaqeysaa qaab demo halkii ay ka lahaan lahayd wax qiimo leh. Laakiin xitaa haddii raadinta-waqtiga dhabta ah aysan ahayn awoodaha GeForce GTX 1660, tani kama dhimayso faa'iidooyinka kale ee xubinta ugu yar ee qoyska Turing. GeForce GTX 1060 ayaa lumisay racfaankeedii hore, iyo dheelitirka awoodda kaararka garaafyada qiimaha dhexe ayaa u wareegay Radeon RX 580 iyo , si kastaba ha ahaatee, alaabada cusub ee chip TU116 ayaa isla markiiba NVIDIA ku soo celisay booska hogaaminta.
Dib u eegista kaararka fiidiyoowga ah ee waxqabadka sare leh, dareenka saxaafaddu wuxuu inta badan diiradda saarayaa moodooyinka qaaliga ah ee leh nidaamyada qaboojinta xooggan, naqshad cajiib ah iyo waxyaabo badan oo dheeraad ah. Laakiin marka ay timaado birta bulk, waxaa aad muhiim u ah in la barto boosaska hoose ee liiska qiimaha. Isticmaalka awoodda hooseeya ee GeForce GTX 1660 waxay kuu ogolaaneysaa inaad si weyn u fududeyso fiilooyinka kaadhka fiidiyowga, isla markaana aad ilaalinayso xad weyn oo badbaado ah oo loogu talagalay xad dhaafka. Aynu baranno ilaa heerka ay fududayntu ku ilaalinayso awoodaha saacadaha xad dhaafka ah anagoo adeegsanayna tusaalaha Inno3D GeForce GTX 1660 Twin X2.
Tilmaamaha farsamada, baaxadda gaarsiinta, qiimaha
Si ka duwan alaabooyinka soo saarayaasha caanka ah ee caanka ah, buug-gacmeedka wax-bixinta casriga ah ee Inno3D maaha mid aad u kala duwan, iyo GeForce GTX 1660 iyo GTX 1660 Ti kaliya ayaa la heli karaa sida moodooyinka Twin X2. Astaantan hoosteeda, Inno3D waxay soo saartay dhawr dardar-geliyayaal dhammaan GPU-yada dhismaha ee Turing - ilaa GeForce RTX 2080 Ti. Mid kasta oo iyaga ka mid ah waxa uu caan ku yahay qiimihiisu la awoodi karo ee suuqa suuqa oo waxa uu ku shaqeeyaa dhawr saacadood oo tixraac ah. Sidaa darteed, inta jeer ee GPU-ga ee Inno3D GeForce GTX 1660 Twin X2 waa 1530 MHz, iyo qiyaasta qiyaasta ee culeyska caadiga ah (kor u qaadista saacadda) waa 1785 MHz. Si kastaba ha noqotee, NVIDIA waxay hoos u dhigtaa awoodda kaararka fiidiyooga, sababtoo ah xitaa ciyaaraha ugu baahida badan, GeForce 10, 16 iyo 20 qalabyada taxanaha ah ayaa badanaa ka badan. Si kastaba ha ahaatee, xaqiiqdii waxaan taas ku ogaan doonaa marxaladda imtixaanka. Sida dhammaan noocyada GeForce GTX 1660, guddiga Inno3D wuxuu wataa 6 GB ee GDDR5 RAM, kaas oo mar kale leh xajmiga tixraaca ee 8 Gbps pin baska.

Suuqa Ruushka, NVIDIA waxay markii hore ku qiimeysay GeForce GTX 1660 17 rubles, laakiin bil ka dib markii la sii daayay badeecada cusub, qiimaha wax ka beddelkeeda kala duwan ayaa ka dhaqaaqay qiimihii lagu taliyey. Noocyada "Premium" ee GTX 990, sida uu qabo Yandex Market, waxay gaaraan 1660 rubles, iyo qaabka "caanka" ee ugu caansan waxaa lagu iibsan karaa 20 oo keliya. - Kani waa Inno240D GeForce GTX 15 Twin X975. Laakiin kama aan helin goobaha ganacsiga shisheeye, sidaas darteed soo dejinta gaarka ah waa inay tixgeliyaan fursadaha kale ee lagu badbaadinayo lacagta.
In kasta oo ay leedahay saamiga wax-qabadka-qiimaha-wanaagga leh, Inno3D GeForce GTX 1660 Twin X2 waxay leedahay xafiiltan u qalma qaybta kaararka garaaf-hoosaadka $250. AMD waxay salaantay soo-bandhiggii ugu horreeyay ee "cagaaran" badeecado cusub iyadoo hoos u dhigtay qiimaha Radeon RX 580 iyo Radeon RX 590. Calanka xawaaraha sare ee Chips Polaris ayaa hadda lagu heli karaa 16 rubles, iyo Radeon RX 261 ee qaabeynta 580 GB RAM - laga bilaabo 8 rubles. Qiimayaashani waxay la jaan qaadayaan sida tartamayaasha loo qaybiyay dib u eegistii ugu horeysay ee GeForce GTX 12. Si kastaba ha ahaatee, AMD waxay kuu ogolaaneysaa inaad hoos u dhigto kharashyada casriyeynta xitaa iyada oo loo marayo moodooyinka Radeon RX 517 oo leh 1660 GB oo xusuusta ah, qiimaha kaas oo bilaabmaya 580 RUB.
In kasta oo uu jaban yahay Inno3D GeForce GTX 1660 Twin X2, kaarka fiidiyowga waxaa ku jiray shay qiimo leh - furayaasha noocyada lacag bixinta ee xirmooyinka 3DMark iyo VRMark. Laakiin ma jiraan qalab kale oo ku jira sanduuqa marka laga reebo saxanka software-ka.
Dhismaha
Duleedka Inno3D GeForce GTX 1660 Twin X2 uma baahna sharraxaad faahfaahsan. Muuqaal ahaan, kaarka fiidiyowgu wax yar ayuu kaga duwan yahay wax ka beddelka miisaaniyada kale ee taxanaha GeForce GTX 10th iyo 16th. Sababtoo ah cabbirkeeda suubban, waxaad u maleyn kartaa inay ku habboon tahay cabbirrada nidaamyada qaab-dhismeedka Mini-ITX, laakiin maya - qalabku waa 1,96 cm ka dheer inta loo baahan yahay 17 cm Dabcan, ma jiro nalka LED-ka ama qurxinta kale ee ikhtiyaariga ah. Xataa saxanka difaaca ee dhabarka PCB-ga ayaa maqan.
Gudaha Inno3D GeForce GTX 1660 Twin X2 waxaa afuufaya laba taageere oo dhexroorkiisu yahay 72 mm. Sababtoo ah xaqiiqda ah in soo-saaraha uusan fidin nidaamka qaboojinta ee ka baxsan cabbirka PCB, sida badanaa lagu sameeyo kaararka fiidiyoowga ah, ma jirin meel ku filan oo loogu talagalay impellers ballaaran. Heerkulka heerkulkiisu yahay 45 Β° C, nidaamka qaboojinta wuxuu ku shaqeeyaa qaab la yaab leh: taageerayaashu waa kuwo taagan mar walba, laakiin dhowrkii ilbiriqsi kasta waxay u yimaadaan nolosha si ay u sameeyaan dhowr kacdoon.
Thanks to isticmaalkeeda awoodda hooseeya (120 W marka loo eego tilmaamaha GeForce GTX 1660), TU116 GPU si wax ku ool ah ayaa loo qaboojiyey heatsink is haysta oo leh naqshad fudud. Si kastaba ha ahaatee, injineerada Inno3D wax kharash ah kama reebin saddex tuubooyinka kulaylka 4 mm oo si toos ah ula xiriira crystal GPU. GIGABYTE, tusaale ahaan, noocyadeeda miisaaniyadeed ee GeForce GTX 1660 iyo GTX 1660 Ti ayaa lagu sameeyay hal gacan.
Looxa wareegga daabacan
Maadaama chips-yada TU116 iyo TU106 ay isweydaarsanayaan marka loo eego is-dhexgalka jireed, xulashooyin badan ayaa ku saleysan GeForce GTX 1660, 1660 Ti, iyo Ρ Waxaa jira loox wareeg ah oo daabacan oo isku mid ah. Soo-saareyaashu waxay beddelaan oo keliya GPU-ga laftiisa, nooca iyo tirada chips-yada xusuusta, iyo qaabeynta jaan-goynta korantada. Marka la eego sifooyinka dibadda, dhammaan moodooyinka Inno3D Twin X2 ilaa GeForce RTX 2070 waxay sidoo kale ku saleysan yihiin isla PCB. Waa wax la yaab leh in ay siddo calaamadda NVIDIA: waxay u muuqataa in Inno3D ay iibsanayso kiristaalo Turing ee aaladahan taxanaha ah oo ay la socdaan guddiyada tixraaca.
PCB-gu waxa uu leeyahay xidhidhyo xidhidhyo ka kooban lix weji oo korantada GPU ah iyo laba weji oo koronto ah oo loogu talagalay chips RAM, laakiin GeForce GTX 1660 kaliya afar iyo hal waji ayaa la iibiyaa, siday u kala horreeyaan. Waa qaabeyn dhexdhexaad ah, laakiin maadaama GeForce GTX 1060 Founders Edition ay leedahay wadar ahaan afar weji, markaa moodalka da'da yar ee chip TU116 waa inuu ku filnaa shan. Xidhiidhka ay la leedahay kaararka fiidiyaha ee taxanaha ah ee GeForce RTX, Inno3D GeForce GTX 1660 Twin X2 korantada korantada waxay ka kooban tahay transistor- saameyn ku yeelanaya darawal gudaha ah (waxa loogu yeero DrMOS, ama "marxalad koronto" - heerar koronto). Marka la barbardhigo lammaanaha darawalka-transistor-ka ee kala duwan, xalka isku dhafan wuxuu bixiyaa waxtarka korodhka wuxuuna u oggolaanayaa kontaroolaha PWM inuu si sax ah u xakameeyo tamarta wax soo saarka.
Awood dheeri ah ayaa lagu siiya kaadhka fiidiyowga iyada oo loo sii marayo isku xidhaha sideed-pin, iyo isku xirka isku xirka dibadda wuxuu ka kooban yahay seddex wax soo saar oo DisplayPort ah iyo hal HDMI. Marka la eego qaabka suufka xiriirka, guddiga wareegga daabacan ee tixraaca wuxuu kuu ogolaanayaa inaad ku bedesho laba xiriiriye DisplayPort oo leh madaxa DVI, kaas oo aad ugu habboon dardargelinta qaaliga ah, laakiin Inno3D kama faa'iidaysan fursadan.
