Mtsogoleri wamkulu wa NVIDIA Jensen Huang adapereka makadi apakanema omwe akuyembekezeredwa kwanthawi yayitali kuchokera kukhitchini yake. Monga momwe zikuyembekezeredwa, mayankho akale adalengezedwa lero: GeForce RTX 3090, GeForce RTX 3080 ndi GeForce RTX 3070. Makhadi a kanema amamangidwa pa Ampere generation GPUs opangidwa pogwiritsa ntchito teknoloji ya Samsung 8nm process, pamene oyambirira awo a Turing anapangidwa pogwiritsa ntchito teknoloji ya 12nm TSMC.
GeForce RTX 3090
Kusintha kwa njira yatsopano, yochepetsetsa yaukadaulo kunapangitsa kuti zitheke kuyika ma transistors ambiri pa chip, chifukwa chomwe midadada yogwira ntchito idakula kwambiri. Tsoka ilo, Jensen Huang sanatchule masanjidwe a GPU, ndipo adangotchula magawo a memory subsystem pakati pamikhalidwe. GeForce RTX 3090 ili ndi 24 GB ya kukumbukira kwa GDDR6X yokhala ndi liwiro la wotchi ya 19,5 GHz. Pamodzi ndi 384-bit wide bus, izi zimapereka memory subsystem bandwidth ya 936 GB/s. GeForce RTX 2080 Ti, kumbukirani, inali ndi 11 GB yokha ya GDDR6 kukumbukira ndi pafupifupi nthawi imodzi ndi theka yocheperapo.
Chiwonetsero chapamwamba cha GPU pamakhadi atsopanowa ndi 36 TFLOPS "ndi mapangidwe azithunzi achikhalidwe pogwiritsa ntchito shading (shaders)" (Shader-TFLOPS). Kuchita pogwira ntchito ndi ray tracing kumanenedwa ku 69 TFLOPS (RT-TFLOPS), ndipo magwiridwe antchito pogwiritsa ntchito ma tensor cores amafika 285 TFLOPS (Tensor-TFLOPS).
Malinga ndi NVIDIA, khadi iyi ya kanema idapangidwa kuti izisewera pa 8K resolution, momwe imatha kupereka 60 FPS yokhazikika. Zimadziwikanso kuti "chilombo" ichi ndi pafupifupi 50% mofulumira pa chisankho cha 4K kuposa Titan RTX.
GeForce RTX 3080
Mtsogoleri wa NVIDIA adatcha khadi la kanema la GeForce RTX 3080 chizindikiro chatsopano, kunyalanyaza funso la zomwe GeForce RTX 3090 ili pa nkhaniyi.
Mwa mawonekedwe, kupezeka kwa 10 GB ya kukumbukira kwa GDDR6X yokhala ndi ma frequency a 19 GHz kunadziwika. Kukumbukira kumalumikizidwa kudzera pa basi ya 320-bit, yomwe pamapeto pake imapereka kutulutsa kwa 760 GB/s. Tikumbukire kuti GeForce RTX 2080 yam'mbuyo inali ndi 8 GB yokha ya GDDR6 kukumbukira ndi bandwidth ya 448 GB/s.
Kuchita kwa GeForce RTX 3080 ndi kumasulira kwachikhalidwe pogwiritsa ntchito shaders ndi 30 TFLOPS (Shader-TFLOPS). Mukakonza kufufuza kwa ray, khadi la kanema limapereka 58 TFLOPS (RT-TFLOPS), ndipo pogwira ntchito pama tensor cores imapereka mpaka 238 TFLOPS (Tensor-TFLOPS). Malinga ndi mutu wa NVIDIA, khadi ya kanema ya GeForce RTX 3080 ndiyopanga kawiri kuposa yomwe idakhazikitsidwa, GeForce RTX 2080.
GeForce RTX 3070
Khadi losavuta kwambiri la atatu omwe aperekedwa, GeForce RTX 3070, monga omwe adatsogolera GeForce RTX 2070, ali ndi 8 GB ya kukumbukira kwa GDDR6.
Mulingo wa magwiridwe antchito a GeForce RTX 3070 graphics accelerator anali 20 TFLOPS ndi kumasulira kwachikhalidwe ndi shaders (Shader-TFLOPS). Kugwira ntchito mukamagwira ntchito ndi ray tracing kumanenedwa ku 40 TFLOPS (RT-TFLOPS), ndipo magwiridwe antchito ndi ma tensor cores amafika 163 TFLOPS (Tensor-TFLOPS). NVIDIA imati GeForce RTX 3070 yatsopano ndiyopanga kwambiri kuposa mbiri yakale - GeForce RTX 2080 Ti.
Zoyamba zatsopano zidzakhala GeForce RTX 3080. Izi zidzachitika mwezi uno - September 17. Mtengo udzakhalabe pamlingo wa omwe adatsogolera - $ 699 (mu Russia - 63 rubles). GeForce RTX 500 yotsika mtengo kwambiri idzawoneka pamashelefu nthawi ina mu Okutobala, ndipo mtengo wake udzakhala $3070 (ma ruble 499) - kachiwiri, pamlingo wa omwe adatsogolera. Potsirizira pake, GeForce RTX 45 idzagulitsidwa pa September 500, yomwe imapezeka nthawi yomweyo kuchokera ku NVIDIA ndi mabwenzi ake, pamtengo ... $ 3090 (24 rubles). Panalibe kukwera mtengo kuno.
