NVIDIA waxay dhawaan sii deysay kaadhka garaafyada ee GeForce GTX 1660 Ti oo ku saleysan TU116 GPU cusub, laakiin dhaqdhaqaaqa naqshadaha Turing ee aaladaha miisaaniyadu wali ma dhamaan. Iyadoo GTX 1660 Ti, shirkaddu waxay ku beddeshay GeForce GTX 1070 oo leh nooc cusub oo la awoodi karo oo leh isticmaalka awoodda hoose, laakiin GeForce GTX 1660 cusub ayaa wajaheysa hawl kale: si loo xiro farqiga u dhexeeya buug-gacmeedka NVIDIA oo weli ka dhex jira GeForce GTX 1060 iyo GTX 1070 Deyrtii hore, Radeon RX 590 waxay degeen farqigan, iyo Radeon RX 580, natiijada wanaajinta darawalka iyo u gudubka ciyaaraha Direct3D 12, waxay noqdeen ugu yaraan beddelka saxda ah ee GeForce GTX 1060. Laakiin Marka la sii daayo GTX 1660, GPU-yada "casaan" waxay leeyihiin tartan culus oo ku jira qaybta tirada badan ee kaararka fiidiyowga macaamiisha, sababtoo ah badeecada cusub ayaa labadaba ka jaban Radeon RX 590 waxayna leedahay karti waxqabad sare.
Tilmaamaha farsamada, qiimaha
GeForce GTX 1660 waxay ku salaysan tahay processor-ka garaafyada ee TU116 oo leh unug xisaabeed oo qayb demi. Farqiga u dhexeeya qaabeynta GPU ee udhaxeysa GTX 1660 iyo GTX 1660 Ti wuxuu hoos ugu soo dhacayaa laba kumbuyuutar oo badan oo qulqulaya (SMs), kuwaas oo wada jir ka kooban 128 32-bit CUDA cores iyo 8 mappers textures. Markaa, wax-soo-saarka GeForce GTX 1660 wuxuu ku dhibtooday kaliya 8,3% hawlgallada dul sabaynta iyo texel-ka buuxinta iyada oo aan la hagaajin xawaaraha saacadaha GPU. Soo noqnoqoshada, habka, ayaa kordhay kaliya qaabka da'da yar: NVIDIA waxay kordhisay soo noqnoqoshada saldhigga 30 MHz, iyo Kordhinta Clock by 15 MHz.
Laakiin isbeddellada khiyaanada leh kuma filna in la kala saaro GeForce GTX 1660 iyo GTX 1660 Ti. Muuqaalka ugu muhiimsan ee kala saaraya labada nooc ayaa ahaa nooca RAM. Iyadoo wax ka beddelka Ti uu ku qalabaysan yahay chips GDDR6 oo leh xajmiga 12 Gbps halkii pin, GeForce GTX 1660 ayaa ku soo noqotay heerka GDDR5. Intaa waxaa dheer, GTX 1660 waxay ku qalabaysan tahay chips oo leh xajmiga xajmiga 8 Gbit / s, taas oo macnaheedu yahay in marka la eego wadarta guud ee xajmiga xusuusta, kaarka fiidiyowga cusub wuxuu si buuxda u waafaqsan yahay sifooyinka bilawga ah ee GeForce GTX 1060 oo leh 6 GB RAM, iyo Noocyada dambe ee GTX 1060 oo leh 9 Gbit/s RAM xitaa way ka sarreeyaan GTX 1660 waxay leedahay cabbirkan. Si kastaba ha noqotee, processor-ka garaafyada TU116, oo ay ugu wacan tahay isku-buufinta midabka ee la hagaajiyay, wuxuu si hufan ula shaqeeyaa RAM.
Maaddaama xawaaraha saacadda iyo qaabeynta GPU ee GeForce GTX 1660 iyo GTX 1660 Ti aysan si weyn u kala duwaneyn, moodelka da'da yari sidoo kale wuxuu wataa chips RAM oo leh awood sare (marka la barbar dhigo GDDR6), labada da'da yar ee qoyska Turing ayaa lagu gartaa. isla kaydka tamarta - 120 W .
Waxaan horay uga wada hadalnay sifooyinka kale ee chip TU116 marka la barbardhigo wakiilada buuxa ee qoyska Turing (TU106, TU104 iyo TU102) ee dib u eegista GeForce GTX 1660 Ti, laakiin waxaa habboon in diiradda la saaro dhowr astaamood oo muhiim ah oo sameeya TU116 oo la mid ah analoos-keeda hore ama, caksigeed, waxay kala sawirtaa xuduud aan laga gudbi karin. Wadar ahaan, TU116 waxay soo bandhigtay dhammaan hal-abuurka ay NVIDIA ka hirgelisay dhismaha Turing, marka laga reebo koofiyadaha sameeya Ray Tracing iyo kombuyuutarrada tensor-ka ee sameeya xisaabinta FMA (Fused-Multiply Add) ee xisaabinta nuska saxda ah ee dhabta ah (FP16). ). Kuwa dambe waxaa loo adeegsadaa inta badan hawlaha barashada mashiinka, marka GPU-gu u gudbiyo xogta shabakada neerfaha ee horay loogu sameeyay gudaha ama beer fog. Sidaa darteed, GeForce GTX 1660 iyo GTX 1660 Ti waxay isku mar lumiyeen iswaafajinta labadaba DXR (Direct3D 12 kordhinta raadinta ray) iyo tignoolajiyada DLSS, taas oo u oggolaanaysa GPU-da inay ku bixiso xalin la dhimay iyada oo la adeegsanayo qaabeynta soo socota iyadoo la adeegsanayo shabakad neerfaha ah.
Halkii unugyada tensor-ka, NVIDIA waxay ku qalabaysay TU116 oo leh noocyo kala duwan oo 16-bit CUDA ah - kuma filna inay si wax ku ool ah u socodsiiyaan DLSS, laakiin waxaa jira ciyaaro hore u isticmaala hawlgallada saxda ah ee nuska xisaabinta shader (tusaale, Wolfenstein II). : The New Colossus), taas oo ay ugu wacan tahay waxqabadka GPU-yada ku habboon (hadda Vega iyo Turing chips) ayaa si weyn u kordheysa. Haddii kale, mar labaad, TU116 waxay kaga duwan tahay chips-kii hore ee qoyskeeda kaliya qaab tiro ahaan, waxay leedahay dhammaan hagaajinta dhuumaha ee ku dhex jira qaab dhismeedka Turing, waxayna taageertaa howlaha wax-is-dejinta sida VRS (Shading Rate Variable).

GeForce GTX 1660 waxaa loogu yeeri karaa seddexaad (ka dib RTX 2060 iyo GTX 1660 Ti) ee ku xiga kaarka fiidiyowga qiimaha dhexe ee qoyska Pascal - GeForce GTX 1060. Laakiin haddii aad indhahaaga xirto qadarka RAM, ka dib marka la eego meesha ay ku jirto safka badeecada cusub waa in lagu barbar dhigaa nooca GeForce GTX 1060 oo leh 3 GB oo RAM ah. Marka la barbar dhigo kuwii ugu dambeeyay, GTX 1660 kaliya ma leh bakhaar labanlaaban, laakiin sidoo kale waxa uu leeyahay 27% wax soo saar fikradeed ka badan qaabkii hore, si la mid ah 1660% GTX 24 Ti wuxuu ka sarreeyaa GTX 1060 buuxa oo buuxa oo leh 6GB ee RAM. Isla mar ahaantaana, NVIDIA kama tagto siyaasadda qiimaha ee ay dejisay qoyska GeForce RTX 20 ee kaararka fiidiyowga, kaas oo dhammaan aaladaha cusubi ay ku qiimeeyaan iibsadaha wax ka badan analogues-kooda tooska ah ee nambarada moodeelka jiilkii hore. Markaa GeForce GTX 1660 wuxuu ku sii socday qiimo lagu taliyey oo ah $229, in kasta oo GeForce GTX 1060 oo leh 3 GB RAM ah uu ku bilaabmay $199.
Markaad eegto qiimaha badeecada cusub, mid ayaa mar kale ka xanaaqi kara damaca NVIDIA, haddii aysan ahayn daciifnimada AMD ee hadda, taas oo, marka la soo bandhigo dhismaha Turing, oo ku faafay qaybta sare ilaa qiimaha dhexe. Markaa, wax ka beddelka ugu jaban ee Radeon RX 590 (oo lagu qiimeeyay $240 barta newegg.com) ayaa hadda ka qaalisan GeForce GTX 1660, iyo suuqa Ruushka, talada NVIDIA (17 rubles) waxay dhigtay GTX 990 qaybta hoose ee kala duwan, kaas oo ay qabsadeen alaabta AMD (laga bilaabo 1660 rubles sida ku xusan market.yandex.ru).
Si ka duwan dardar-geliyayaasha kale ee Chips Turing, oo ay ku jiraan GeForce GTX 1660 Ti, GTX 1660 kuma laha tartame toos ah xeradiisa. Noocyada 10-taxane ee ugu dhow marka loo eego qeexitaannada iyo waxqabadka - GeForce GTX 1060 6 GB iyo GeForce GTX 1070 - aad ayey uga fog yihiin badeecada cusub ee qiimaha, inkasta oo kan ugu horreeya (iyo GTX 1060 hadda lagu iibiyo qiimayaal ka bilaabmaya $ 209 ama 14). Rubles) ayaa wali dib loo dhigi doonaa si ay ula wareegaan qaar ka mid ah iibsadaha suurtagalka ah ilaa kaydka qalabkii hore ee NVIDIA ee ururay intii lagu jiray kobaca cryptocurrency uu dhamaanayo.
GIGABYTE GeForce GTX 1660 OC: naqshadeynta
Aragtida ugu horreysa ee kaadhka garaafyada cusub ee qaybta qiimaha hoose iyo dhexe (iyo, runtii, ku saabsan moodooyinka qaaliga ah sidoo kale) ayaa sida ugu wanaagsan loo sameeyay iyadoo la adeegsanayo wax ka beddel fudud tusaale ahaan, sababtoo ah kuwani waa kuwa ugu baahida badan - si ka duwan " nooca premium” oo ku salaysan isla GPU , kaas oo qiimihiisu inta badan dhex galaa inta u dhaxaysa nooca ugu dhow. Dareenkan, mar labaad ayaan nasiib badan nahay, maxaa yeelay GeForce GTX 1660 waxay u taagan tahay aalad GIGABYTE ah oo laga sii daayay taxanaha caanka ah ee WINDFORCE iyo AORUS. Ma khaldami doontid haddii aad sawirada ka aqoonsato kaadhka fiidiyooga ah ee aan ku tijaabinay seddex toddobaad ka hor dib u eegista GeForce GTX 1660 Ti - waxay isticmaashaa isla guddiga wareegga iyo qaboojinta, laakiin leh GPU kala duwan iyo GDDR5 chips halkii GDDR6 .
GPU-ga ku yaal guddiga GIGABYTE GeForce GTX 1660 OC ayaa horay loo xiray. In kasta oo aynaan ogaan doonin xogta saxda ah ee ku saabsan inta jeer ee la qiimeeyay ilaa daabacaadda maqaalka, marka soo-saaraha uu ku dhejiyo sharaxaadda alaabta cusub shabakadeeda, waxay mar horeba ka caddahay nidaamka qaboojinta suubban in xad dhaafka halkan uu yahay calaamad kaliya. . Iyo GIGABYTE waxay ku dartay moodkii hore 30 MHz oo keliya.
Naqshadeynta GIGABYTE GeForce GTX 1660 OC waxay muujineysaa calaamadaha dhaqaalaha oo dhan. Kaarka fiidiyowga waxaa ka maqan xitaa iftiinka dambe ee ugu fudud, oo aan lagu xusin RGB LEDs oo leh midab la beddeli karo iyo awoodda isku xirka xargaha LED. Xirmada, oo gebi ahaanba ka samaysan balaastig, waxay ku xidhaysaa PCB-ga saddex dhinac, taas oo qarinaysa cabbirrada is haysta ee PCB-ga.
Nidaamka qaboojinta sidoo kale aad ayuu u fudud yahay: kulaylka GPU-yada iyo chips-ka RAM waxaa daadiya hiitarka aluminium, iyo qaybta kaliya ee naxaasta ah waa tuubo kulaylka oo dhexmarta salkeeda. Si kastaba ha noqotee, qaboojiyaha GIGABYTE GeForce GTX 1660 OC ma aha wax horumarin ah. Sidaa darteed, radiatoor-ku waxa uu leeyahay soo bixid marka uu la xidhiidho transistor-ka saamaynta ku leh goobta iyo maroojinaha danabku, iyo laba taageere oo dhexroorkiisu yahay 87 mm waxay u wareegaan jihooyin ka soo horjeeda - sidaas awgeed waxay yaraynaysaa qaska socodka hawada.

Xirmada xirmada ee GIGABYTE GeForce GTX 1660 OC waa sida ugu macquulsan: marka lagu daro kaarka fiidiyowga laftiisa, sanduuqa waxaa ku jira tilmaamo waraaqo ah oo keliya iyo saxan softiweer ah.
GIGABYTE GeForce GTX 1660 OC: PCB
Iyada oo ku saleysan PCB-ga loo isticmaalo GeForce GTX 1660, GIGABYTE waxay horey u soo saartay qalab kale oo badan, laga bilaabo GeForce GTX 1660 Ti ilaa GeForce RTX 2070. Noocyada noocyadan waxaa ka mid ah GPU-yada kala duwan (TU116, TU106) iyo laba nooc oo RAM ah. chips (GDDR5 iyo GDDR6) koronto ahaan waa ku habboon yihiin, cabbirrada yaryar ee PCB-ga ayaa suurtageliyay in la soo saaro labada aaladood ee cabbirrada caadiga ah iyo kaararka fiidiyowga is haysta ee qaabka Mini ITX.
PCB-gani wuxuu aqbali karaa qaybaha siddeed weji ee xakamaynta korantada, laakiin isticmaalka awoodda aaladaha ku saleysan TU116 iyo TU106 waxay u dhexeysaa 120 ilaa 175 W (sida ku cad tilmaamaha tixraaca), sidaa darteed xawaaraha-dhamaadka hoose wuxuu ku qanacsan yahay lix waji. VRM: afar weji ayaa u adeega GPU-ga iyo laba- microcircuits kaydinta kaydinta random. Sababtoo ah xiriirka ay la leedahay moodooyinka da'da weyn ee qoyska Turing, badeecada cusub waxay ku qalabaysan tahay transistor-ku-salaysan oo leh darawal isku-dhafan (waxa loogu yeero DrMOS ama "marxalad koronto" - marxaladaha awoodda), kuwaas oo bixiya waxtar sare leh oo u oggolaanaya VRM PWM kontaroolaha si uu si sax ah ugu duubo danab ka biya shubanka transistor-ka.
In kasta oo TU116 kontaroolaha soo bandhigida uu yahay DVI ku habboon yahay, GIGABYTE waxay dooratay seddex isku xirayaasha DisplayPort iyo hal wax soo saar HDMI ah. Laakiin GeForce GTX 3.1 iyo GTX 2 Ti ayaa asal ahaan laga saaray USB 1660 Gen 1660 interface oo taageero u ah borotokoolka DisplayLink. Xidhiidhka suufka loogu talagalay la socodka voltka iyo qalabka voltmode, kaydka BIOS chip iyo waxyaabo kale oo la mid ah ayaa sidoo kale, dabcan, halkan ka maqan.
