Mukuru weNVIDIA Jensen Huang akapa makadhi evhidhiyo emitambo akamirirwa kwenguva refu kubva kukicheni yake. Sezvaitarisirwa, zvigadziriso zvekare zvakaziviswa nhasi: GeForce RTX 3090, GeForce RTX 3080 uye GeForce RTX 3070. Makadhi evhidhiyo akavakwa paAmpere generation GPUs akaitwa achishandisa Samsung's 8nm process technology, nepo vatangiri vavo veTuring vakagadzirwa vachishandisa 12nm teknolojia TSMC.
GeForce RTX 3090
Shanduko kune itsva, yakaonda tekinoroji maitiro akaita kuti zvikwanise kuisa akawanda akawanda transistors pane chip, nekuda kwekuti nhamba yezvivharo zvinoshanda yakawedzera zvakanyanya. Nehurombo, Jensen Huang haana kutsanangura magadzirirwo eGPU, uye akangotumidza maparamita eiyo memory subsystem pakati pehunhu. Iyo GeForce RTX 3090 ine 24 GB yeGDDR6X ndangariro ine inoshanda wachi yekumhanya ye19,5 GHz. Pamwe chete ne384-bit yakafara bhazi, izvi zvinopa memory subsystem bandwidth ye936 GB/s. Iyo GeForce RTX 2080 Ti, rangarira, yaingova negumi negumi chete GB yeGDDR11 ndangariro ine imwe nehafu nguva shoma bandwidth.
Iyo yepamusoro theoretical GPU kuita kweiyo vhidhiyo kadhi nyowani ndeye 36 TFLOPS "nechinyakare chivakwa chemufananidzo uchishandisa shading (shaders)" (Shader-TFLOPS). Kuita kana uchishanda neray tracing kunotaurwa pa69 TFLOPS (RT-TFLOPS), uye kuita mukushanda uchishandisa tensor cores kunosvika 285 TFLOPS (Tensor-TFLOPS).
Maererano neNVIDIA, iyi kadhi yevhidhiyo yakagadzirirwa kutamba pa8K resolution, iyo inokwanisa kupa yakagadzikana 60 FPS. Zvinocherechedzwa zvakare kuti "chikara" ichi chinenge 50% nekukurumidza pakugadziriswa kwe4K kupfuura Titan RTX.
GeForce RTX 3080
Mukuru weNVIDIA akadana GeForce RTX 3080 kadhi revhidhiyo mureza mutsva, achinzvenga mubvunzo wekuti GeForce RTX 3090 iri chii munyaya iyi.
Pakati pehunhu, kuvepo kwe10 GB yeGDDR6X ndangariro ine frequency inoshanda ye19 GHz yakacherechedzwa. Iyo ndangariro yakabatana kuburikidza ne320-bit bhazi, iyo inozopedzisira yapa kuburikidza ne760 GB/s. Ngatiyeukei kuti yapfuura GeForce RTX 2080 yaingova ne8 GB yeGDDR6 ndangariro ine bandwidth ye448 GB/s.
Kuita kweGeForce RTX 3080 ine tsika yechinyakare kushandisa shaders ndeye 30 TFLOPS (Shader-TFLOPS). Kana uchigadzira ray tracing, vhidhiyo kadhi inopa makumi mashanu nesere TFLOPS (RT-TFLOPS), uye mukushanda pane tensor cores inopa kusvika ku58 TFLOPS (Tensor-TFLOPS). Zvinoenderana nemusoro weNVIDIA, iyo GeForce RTX 238 vhidhiyo kadhi inobereka zvakapetwa kaviri seyakatangira, iyo GeForce RTX 3080.
GeForce RTX 3070
Iyo yakapfava kadhi yevatatu vakaunzwa, GeForce RTX 3070, seyakatangira GeForce RTX 2070, ine 8 GB yeGDDR6 ndangariro.
Chiyero chekuita cheGeForce RTX 3070 graphics accelerator yaive makumi maviri TFLOPS ine yechinyakare kupa ine shader (Shader-TFLOPS). Kuita kana uchishanda neray tracing kunotaurwa ku20 TFLOPS (RT-TFLOPS), uye kuita mukushanda nematensor cores kunosvika 40 TFLOPS (Tensor-TFLOPS). NVIDIA inotaura kuti GeForce RTX 163 itsva inobereka zvakanyanya kupfuura yaimbova mureza - GeForce RTX 3070 Ti.
Yekutanga yezvigadzirwa zvitsva ichava GeForce RTX 3080. Izvi zvichaitika mwedzi uno - Gunyana 17. Mari yacho icharamba iri pamwero wevakatangira - $ 699 (muRussia - 63 rubles). Iyo inonyanya kudhura GeForce RTX 500 ichaonekwa pamasherufu imwe nguva muna Gumiguru, uye mutengo wayo uchave $3070 (499 rubles) - zvakare, pamwero weakatangira. Pakupedzisira, iyo GeForce RTX 45 ichaenda kutengeswa musi waSeptember 500, pakarepo inowanikwa kubva kuNVIDIA nevamwe vayo, nemutengo we ... $ 3090 (24 rubles). Pakanga pasina kuwedzera mutengo pano.
