NVIDIA waxay soo bandhigtay jiilka cusub ee kaararka garaafyada ciyaaraha Ampere Sebtember 1, laakiin soo bandhigida bilowga ah kuma koobna wax tafaasiil farsamo ah. Hadda, dhowr maalmood ka dib, shirkaddu waxay soo saartay dukumeenti caddaynaya halka faa'iidada waxqabadka cajiibka ah ee dejisa kaararka garaafyada ee GeForce RTX 30 marka laga reebo kuwii ka horreeyay.
Dad badan ayaa isla markiiba ogaaday in qeexitaannada rasmiga ah ee GeForce RTX 3090, GeForce RTX 3080 iyo GeForce RTX 3070 ee shabakadda NVIDIA ay muujiyeen tiro aad u badan oo soo-saarayaal CUDA ah.
Sida ay soo baxday, laba-laabashada waxqabadka FP32 ee soo-saareyaasha ciyaaraha Ampere marka la barbar dhigo Turing runtii way dhacdaa, waxayna la xiriirtaa isbeddelka qaab dhismeedka dhismooyinka aasaasiga ah ee GPU - stream processors (SM).
In kasta oo SM-yada jiilka Turing GPU ay haysteen hal waddo oo xisaabin ah oo loogu talagalay hawlgallada dul sabeynaya, Ampere kasta oo processor-ka durdurku wuxuu helay laba waddo, kuwaas oo wadar ahaan qaban kara illaa 128 hawlgallada FMA saacaddiiba marka loo eego 64 ee Turing. Isla mar ahaantaana, kala badh ka mid ah qaybaha fulinta Ampere ee la heli karo waxay awood u leeyihiin inay fuliyaan labadaba hawlgallada isku-dhafka ah (INT) iyo 32-bit floating point (FP32), halka qaybta labaad ee qalabka loogu talagalay hawlgallada FP32. Habkan waxaa loo adeegsaday si loo badbaadiyo miisaaniyada transistor-ka, iyadoo lagu salaynayo xaqiiqda ah in culeyska ciyaaruhu uu soo saaro FP32 aad uga badan hawlgallada INT. Si kastaba ha ahaatee, Turing ma jirin hawl-wadeenno la isku daray gabi ahaanba.
Isla mar ahaantaana, si loo helo soo-saareyaasha qulqulka la xoojiyey ee xogta lagama maarmaanka u ah, NVIDIA waxay kordhisay cabbirka kaydka L1 ee SM saddex meelood meel (laga bilaabo 96 ilaa 128 KB), waxayna sidoo kale labanlaabtay wax soo saarkeeda.
Horumarka kale ee muhiimka ah ee Ampere waa in CUDA, RT iyo Tensor cores ay hadda si buuxda u socon karaan si isbarbar socda. Tani waxay u oggolaanaysaa mashiinka garaafyada, tusaale ahaan, inuu isticmaalo DLSS si uu u cabbiro hal xargo, isla markaana isla mar ahaantaana xisaabin jirkiisa soo socda ee CUDA iyo RT, yaraynta wakhtiga hoos u dhaca qanjidhada shaqada iyo kordhinta waxqabadka guud.
Tan waa in aan ku darnaa in jiilka labaad ee RT cores, oo laga hirgeliyay Amrere, ay xisaabin karaan isgoysyada saddexagalka leh fallaadho laba jeer sida ugu dhakhsaha badan ee ka dhacday Turing. Iyo jiilka seddexaad ee cusub ee kombuyuutarrada ayaa labanlaabay waxqabadka xisaabta marka ay la shaqeynayaan matrisyo yaryar.
Laba-laabista xawaaraha uu Ampere ku xisaabinayo is-goysyada saddex-xagalka ah waa inay saameyn weyn ku yeelato waxqabadka dardar-geliyayaasha taxanaha-GeForce RTX 30 ee ciyaaraha taageeraya raadinta raajo. Sida laga soo xigtay NVIDIA, waxay ahayd sifadaas tan u shaqeysa sidii ciribtirka dhismaha Turing, halka xawaaraha xisaabinta ee isgoysyada fallaadhaha isbarbar-dhigga ah aysan soo kicin wax cabasho ah. Hadda dheelitirnaanta waxqabadka raadinta ayaa la hagaajiyay, sidoo kale, Ampere, labada nooc ee hawlgallada raajada (oo leh saddex-xagal iyo barbar-yaal) ayaa la samayn karaa si isku mid ah.
Taas waxa dheer, hawlkar cusub ayaa lagu daray Ampere's RT cores si ay u dhexgalaan booska saddexagalka. Tan waxaa loo isticmaali karaa in lagu qariyo walxaha dhaqdhaqaaqa marka dhammaan saddexagalka goobta aysan ku jirin meel joogto ah.
Si loo muujiyo waxaas oo dhan, NVIDIA waxay muujisay isbarbardhigga tooska ah ee sida Turing iyo Ampere GPUs ay u maareeyaan raadinta rayiga Wolfenstein Youngblood ee xallinta 4K. Sida soo socota sawirka la soo bandhigay, Ampere waxay si muuqata uga faa'iidaysan kartaa xawaaraha dhismaha qaabdhismeedka labadaba iyadoo ay ugu wacan tahay xisaabinta xisaabaadka FP32 ee degdegga ah, iyada oo ay ugu wacan tahay jiilka labaad ee RT, iyo sidoo kale hawlgalka isbarbar socda ee agabyada kala duwan ee GPU.
Intaa waxaa dheer, si ficil ahaan loo xoojiyo kor ku xusan, NVIDIA waxay soo bandhigtay natiijooyin imtixaan dheeraad ah oo loogu talagalay GeForce RTX 3090, GeForce RTX 3080 iyo GeForce RTX 3070. Sida laga soo xigtay iyaga, GeForce RTX 3070 waa qiyaastii 60% ka hor GeForce RTX 2070 ee 1440p xallinta, waxaana sawirkan lagu arkay ciyaaraha taageerada RTX, iyo rasterization dhaqameed, gaar ahaan Borderlands 3.
Waxqabadka GeForce RTX 3080 wuxuu laba jeer ka wanaagsan yahay kan GeForce RTX 2080 ee xallinta 4K. Run, kiiskan, Borderlands 3 iyada oo aan la helin taageerada RTX, faa'iidada kaadhka cusub maaha labanlaab, laakiin qiyaastii 80 boqolkiiba.
Iyo kaarka hore, GeForce RTX 3090, ee NVIDIA tijaabooyinkiisa gaarka ah waxay muujinayaan ku dhawaad ββββhal jeer iyo badh faa'iidada Titan RTX.
Sida laga soo xigtay warbixinnada saxafiyiinta teknolojiyadda, dib u eegista buuxda ee naqshadeynta tixraaca ee GeForce RTX 3080 ayaa lagu wadaa in la daabaco Sebtember 14-keeda. Saddex maalmood ka dib, Sebtember 17, waxaa loo oggolaan doonaa inay daabacdo xogta tijaabada ah ee wax soo saarka GeForce RTX 3080 ee la-hawlgalayaasha shirkadda. Sidaa darteed, waxaa jira waqti aad u yar oo ka haray in la sugo natiijooyinka imtixaannada madaxbannaan ee wakiillada taxanaha GeForce RTX 30 si ay uga muuqdaan internetka.
