NVIDIA yakaunza chizvarwa chitsva cheAmpere emitambo yemakadhi makadhi munaGunyana 1, asi yekutanga mharidzo yaive isina ruzivo rwehunyanzvi. Ikozvino, mazuva mashoma gare gare, kambani yakaburitsa zvinyorwa zvinojekesa uko kunoshamisa kwekuita mukana unoseta iyo GeForce RTX 30-yakatevedzana makadhi emifananidzo kunze kwevakaitangira inobva.
Vazhinji vakabva vaona kuti zviri pamutemo zvakatemwa zveGeForce RTX 3090, GeForce RTX 3080 uye GeForce RTX 3070 pawebhusaiti yeNVIDIA yakaratidza huwandu hunoshamisa hweCUDA processors.
Sezvazvinoitika, kupetwa kaviri kweFP32 kuita kweAmpere emitambo processors zvichienzaniswa neTuring kunoitika zvechokwadi, uye kune hukama neshanduko yezvivakwa zvezvivakwa zvekuvaka zveGPU - stream processors (SM).
Nepo maSM ari muTuring chizvarwa maGPU aive nekamwe kanzira kekutenderera kekutenderera kwenzvimbo, muAmpere yega yega processor yakagamuchira nzira mbiri, iyo yakazara inogona kuita 128 FMA mashandiro pawachi kutenderera 64 yeTuring. Panguva imwecheteyo, hafu yeanowanikwa Ampere execution units inokwanisa kuita ese arise ari maviri (INT) mashandiro uye 32-bit inoyangarara nzvimbo (FP32) mashandiro, nepo hafu yechipiri yemidziyo inoitirwa chete FP32 mashandiro. Iyi nzira yakashandiswa kuchengetedza iyo transistor bhajeti, zvichibva pachokwadi chekuti mutambo wekutamba unoburitsa zvakanyanya FP32 pane INT mashandiro. Nekudaro, muTuring pakanga pasina akasanganiswa actuator zvachose.
Panguva imwecheteyo, kuitira kupa akakwidziridzwa erukova processors nehuwandu hunodiwa hwe data, NVIDIA yakawedzera saizi yeL1 cache muSM nechikamu chetatu (kubva pa96 kusvika 128 KB), uye yakawedzera kaviri kubuda kwayo.
Imwe budiriro yakakosha muAmpere ndeyekuti CUDA, RT uye Tensor cores zvino inogona kumhanya zvizere mukufanana. Izvi zvinobvumira injini yemifananidzo, semuenzaniso, kushandisa DLSS kuyera imwe furemu, uye panguva imwechete kuverenga iyo inotevera furemu paCUDA uye RT cores, kuderedza kuderera kweanodhi inoshanda uye kuwedzera kushanda kwese.
Kune izvi isu tinofanirwa kuwedzera kuti chizvarwa chechipiri RT cores, icho chinoshandiswa muAmrere, chinogona kuverenga mharadzano dzematatu nemwaranzi kaviri nekukurumidza sezvakaitika muTuring. Uye iyo nyowani yechitatu-chizvarwa tensor cores yakawedzera kaviri kuita kwemasvomhu kana uchishanda nema sparse matrices.
Kupeta kaviri kumhanya uko Ampere inoverengera makona matatu kunofanirwa kuve nekukanganisa kukuru pakuita kweGeForce RTX 30-yakatevedzana accelerators mumitambo inotsigira ray tracing. Sekureva kweNVIDIA, chaive hunhu uhwu hwakaita sebhodhoro muTuring architecture, nepo kumhanya kwekuverenga kwemharadzano yemaranzi ekusunga parallelepipeds hakuna kusimudza chero zvichemo. Ikozvino mwero wekuita mukuronda wakagadziridzwa, uyezve, muAmpere, ese ari maviri marudzi ekuvhiya kwemwaranzi (ane matriangles uye parallelepipeds) anogona kuitwa mukuwirirana.
Pamusoro peizvi, mashandiro matsva akawedzerwa kuAmpere's RT cores kuti apinze nzvimbo yematatu. Izvi zvinogona kushandiswa kudzima zvinhu zviri kufamba kana asiri makona matatu ari pachiitiko anogara akamira.
Kuenzanisira zvese izvi, NVIDIA yakaratidza kuenzanisa kwakananga kwemaitiro eTuring uye Ampere GPUs anobata ray tracing muWolfenstein Youngblood pa4K resolution. Sezvinotevera kubva pamufananidzo wakaunzwa, Ampere zvinooneka zvinobatsira mukumhanya kwekuvaka zvese nekuda kwekukurumidza kwemasvomhu FP32 kuverenga, nekuda kwechizvarwa chechipiri RT cores, pamwe nekushanda kwakafanana kweiyo heterogeneous GPU zviwanikwa.
Pamusoro pezvo, kuti tisimbise zviri pamusoro, NVIDIA yakaunza mimwe miedzo yeGeForce RTX 3090, GeForce RTX 3080 uye GeForce RTX 3070. Maererano navo, GeForce RTX 3070 ingangoita 60% pamberi peGeForce RTX 2070 mu1440p resolution, uye mufananidzo uyu unoonekwa mumitambo ine RTX rutsigiro, uye nechinyakare rasterization, kunyanya muBorderlands 3.
Kuita kweGeForce RTX 3080 kwakanaka zvakapetwa kaviri pane kweGeForce RTX 2080 pa4K resolution. Ichokwadi, munyaya iyi, muBorderlands 3 pasina RTX kutsigirwa, mukana wekadhi idzva hauna kaviri, asi inenge 80 muzana.
Uye kadhi rekare, GeForce RTX 3090, mune NVIDIA's bvunzo inoratidza ingangoita kamwechete nehafu mukana pamusoro peTitan RTX.
Zvinoenderana nemishumo kubva kuvatori venhau vetekinoroji, wongororo izere yeGeForce RTX 3080 referensi dhizaini inofanirwa kuburitswa munaGunyana 14. Mazuva matatu gare gare, munaGunyana 17, ichabvumidzwa kuburitsa bvunzo data yekugadzira GeForce RTX 3080 modhi kubva kune vanobatana nekambani. Saka, pane nguva shoma yasara yekumirira mhedzisiro yekuzvimiririra bvunzo dzevamiriri veGeForce RTX 30 dzakatevedzana kuti dzioneke paInternet.
