NVIDIA idayambitsa m'badwo watsopano wa makadi ojambula a Ampere pa Seputembara 1, koma ulaliki woyamba unalibe zambiri zaukadaulo. Tsopano, patatha masiku angapo, kampaniyo yatulutsa zolembedwa zomwe zimamveketsa bwino komwe mwayi wochititsa chidwi womwe umayika makadi ojambula a GeForce RTX 30-mndandanda wosiyana ndi omwe adatsogolera amachokera.
Ambiri adazindikira nthawi yomweyo kuti zomwe GeForce RTX 3090, GeForce RTX 3080 ndi GeForce RTX 3070 patsamba la NVIDIA zidawonetsa kuchuluka kwakukulu kwa mapurosesa a CUDA.
Zotsatira zake, kuwirikiza kawiri kwa FP32 kwa mapurosesa amasewera a Ampere poyerekeza ndi Turing kumachitikadi, ndipo kumalumikizidwa ndi kusintha kwa kamangidwe kazomangamanga za GPU - stream processors (SM).
Ngakhale ma SM mum'badwo wa Turing GPUs anali ndi njira imodzi yolumikizira malo oyandama, ku Ampere purosesa iliyonse yamtsinje idalandira njira ziwiri, zomwe zimatha kugwira ntchito mpaka 128 FMA pa wotchi iliyonse motsutsana ndi 64 ya Turing. Nthawi yomweyo, theka la magawo opha anthu a Ampere amatha kugwira ntchito zonse ziwiri (INT) ndi 32-bit floating point (FP32), pomwe theka lachiwiri la zidazo zimapangidwira ntchito za FP32 zokha. Njirayi idagwiritsidwa ntchito kupulumutsa bajeti ya transistor, kutengera kuti kuchuluka kwamasewera kumapanga kwambiri FP32 kuposa ntchito za INT. Komabe, ku Turing kunalibe ma actuators ophatikizana konse.
Nthawi yomweyo, kuti apereke mapurosesa okhathamira ndi kuchuluka kofunikira kwa data, NVIDIA idakulitsa kukula kwa cache ya L1 mu SM ndi gawo limodzi mwa magawo atatu (kuchokera 96 ββmpaka 128 KB), ndikuwonjezeranso kutulutsa kwake.
Kusintha kwina kofunikira mu Ampere ndikuti ma CUDA, RT ndi Tensor cores tsopano amatha kuyenda limodzi. Izi zimalola injini yojambula zithunzi, mwachitsanzo, kugwiritsa ntchito DLSS kukulitsa chimango chimodzi, ndipo nthawi yomweyo kuwerengera chimango chotsatira pa CUDA ndi RT cores, kuchepetsa nthawi yopuma ya node zogwira ntchito ndikuwonjezera ntchito yonse.
Pazimenezi tiyenera kuwonjezera kuti m'badwo wachiwiri wa RT cores, womwe umagwiritsidwa ntchito ku Amrere, ukhoza kuwerengera maulendo a katatu ndi kuwala kawiri mofulumira monga momwe zinachitikira ku Turing. Ndipo ma tensor cores atsopano a m'badwo wachitatu adachulukitsa masamu pogwira ntchito ndi ma matrices ochepa.
Kuchulukitsa liwiro lomwe Ampere amawerengetsera mphambano za makona atatu kuyenera kukhudza kwambiri magwiridwe antchito a GeForce RTX 30-series accelerators pamasewera omwe amathandizira kufufuza kwa ray. Malinga ndi NVIDIA, chinali chikhalidwe ichi chomwe chinakhala ngati botolo mu zomangamanga za Turing, pamene kuthamanga kwa mawerengedwe a mphambano ya kuwala kwa parallelepipeds sikunadzutse madandaulo. Tsopano kuchuluka kwa magwiridwe antchito pakutsata kwakonzedwa, komanso ku Ampere, mitundu yonse iwiri ya ma ray (okhala ndi makona atatu ndi ma parallelepipeds) amatha kuchitidwa mofanana.
Kuphatikiza pa izi, magwiridwe antchito atsopano awonjezedwa ku Ampere's RT cores kuti asinthe malo a katatu. Izi zitha kugwiritsidwa ntchito kusokoneza zinthu zomwe zikuyenda pomwe simakona atatu onse omwe ali pamalopo omwe sakhazikika.
Kuti tiwonetse zonsezi, NVIDIA idawonetsa kufananitsa kwachindunji momwe ma Turing ndi Ampere GPU amagwirira ntchito kutsata kwa ray mu Wolfenstein Youngblood pa 4K resolution. Motsatira fanizo lomwe likuwonetsedwa, Ampere amapindula bwino pakumanga chimango chifukwa cha kuwerengera mwachangu kwa masamu a FP32, chifukwa cha m'badwo wachiwiri wa RT cores, komanso magwiridwe antchito amtundu wa GPU.
Kuphatikiza apo, kuti atsimikizire zomwe zili pamwambapa, NVIDIA idapereka zotsatira zowonjezera za GeForce RTX 3090, GeForce RTX 3080 ndi GeForce RTX 3070. Malinga ndi iwo, GeForce RTX 3070 ili pafupifupi 60% patsogolo pa GeForce RTX 2070 mu 1440p resolution, ndipo chithunzichi chikuwonetsedwa m'masewera omwe ali ndi chithandizo cha RTX, komanso ndi chikhalidwe chachikhalidwe, makamaka ku Borderlands 3.
Kuchita kwa GeForce RTX 3080 ndikwabwino kawiri kuposa kwa GeForce RTX 2080 pamalingaliro a 4K. Zowona, pankhaniyi, ku Borderlands 3 popanda thandizo la RTX, mwayi wa khadi latsopano siwiri, koma pafupifupi 80 peresenti.
Ndipo khadi yakale, GeForce RTX 3090, pamayesero ake a NVIDIA ikuwonetsa mwayi wanthawi imodzi ndi theka kuposa Titan RTX.
Malinga ndi malipoti ochokera kwa atolankhani aukadaulo, ndemanga zonse za kapangidwe ka GeForce RTX 3080 ziyenera kusindikizidwa pa Seputembara 14. Patatha masiku atatu, pa Seputembara 17, idzaloledwa kufalitsa zoyeserera zamitundu ya GeForce RTX 3080 kuchokera kwa anzawo akampani. Chifukwa chake, kwatsala nthawi yochepa kuti tidikire kuti zotsatira za mayeso odziyimira pawokha a oimira GeForce RTX 30 mndandanda awonekere pa intaneti.
