Ua hoʻokuʻu hou ʻo NVIDIA i ke kāleka kiʻi pāʻani ʻo GeForce GTX 1660 Ti e pili ana i ka TU116 GPU hou, akā ʻaʻole i pau ka neʻe ʻana o ka hale hoʻolālā Turing i nā polokalamu kālā. Me ka GTX 1660 Ti, ua hoʻololi ka hui i ka GeForce GTX 1070 me kahi hiʻohiʻona hou a ʻoi aku ke kumukūʻai me ka hoʻohana haʻahaʻa haʻahaʻa, akā ʻo ka GeForce GTX 1660 hou e kū nei i kahi hana ʻē aʻe: e pani i ke āpau i ka palapala NVIDIA e kū nei ma waena o ka GeForce GTX. 1060 a me GTX 1070 I ka hāʻule hope, ua noho ka Radeon RX 590 i kēia āpau, a ʻo ka Radeon RX 580, ma muli o ka hoʻokele optimization a me ka hoʻololi ʻana o nā pāʻani i Direct3D 12, ua lilo ia i mea ʻokoʻa kūpono i ka GeForce GTX 1060. Akā. me ka hoʻokuʻu ʻana o ka GTX 1660, he hoʻokūkū koʻikoʻi nā GPU "ʻulaʻula" i ka ʻāpana nui o nā kāleka wikiō mea kūʻai aku, no ka mea, ʻoi aku ka maikaʻi o ka huahana hou ma mua o ka Radeon RX 590 a ʻoi aku ka kiʻekiʻe o ka hana.
Nā hiʻohiʻona ʻenehana, kumukūʻai
Hoʻokumu ʻia ka GeForce GTX 1660 ma luna o ke kaʻina hana kiʻi TU116 me nā ʻāpana helu hoʻopaʻa ʻia. ʻO ka ʻokoʻa o ka hoʻonohonoho GPU ma waena o ka GTX 1660 a me GTX 1660 Ti e iho mai i ʻelua streaming multiprocessors (SMs), i hui pū ʻia me 128 32-bit CUDA cores a me 8 texture mappers. No laila, ʻo ka GeForce GTX 1660 throughput i loaʻa i ka 8,3% wale nō i nā hana floating point a me ka hoʻopiha piha ʻana o ka texel me ka ʻole o ka hoʻoponopono ʻana i ka wikiwiki o ka uaki GPU. A ʻo nā alapine, ma ke ala, ua hoʻonui wale ʻia i ke ʻano ʻōpio: ua hoʻonui ʻo NVIDIA i ka base frequency e 30 MHz, a me ka Boost Clock e 15 MHz.
Akā ʻaʻole lawa kēlā mau loli maʻalahi e hoʻokaʻawale i ka GeForce GTX 1660 a me GTX 1660 Ti. ʻO ka hiʻohiʻona nui e hoʻokaʻawale ana i nā hiʻohiʻona ʻelua ʻo ke ʻano o RAM. ʻOiai ua hoʻolako ʻia ka hoʻololi Ti me nā pahu GDDR6 me ka bandwidth o 12 Gbps i kēlā me kēia pine, ua hoʻi ka GeForce GTX 1660 i ka maʻamau GDDR5. Eia kekahi, ua lako ka GTX 1660 me nā chips me ka bandwidth o 8 Gbit / s, ʻo ia hoʻi ma ke ʻano o ka bandwidth hoʻomanaʻo holoʻokoʻa, hoʻokō piha ka kāleka wikiō hou i nā kikoʻī hoʻomaka o ka GeForce GTX 1060 me 6 GB RAM, a me ka ʻO nā mana hope o ka GTX 1060 me 9 Gbit / s RAM ʻoi aku ka maikaʻi ma mua o ka GTX 1660 i kēia ʻāpana. Eia nō naʻe, ʻoi aku ka maikaʻi o ka hana kiʻi TU116, e hoʻomaikaʻi i ka hoʻopiʻi ʻana i ka kala.
No ka mea ʻaʻole ʻokoʻa ka wikiwiki o ka uaki a i ʻole ka hoʻonohonoho GPU o ka GeForce GTX 1660 a me GTX 1660 Ti, a ʻo ke ʻano ʻōpio ke lawe pū nei i nā pahu RAM me ka hoʻohana mana kiʻekiʻe (hoʻohālikelike ʻia me GDDR6), ua ʻike ʻia nā ʻōpio ʻelua accelerators o ka ʻohana Turing. e ka mana hoʻokahi - 120 W .
Ua kūkākūkā mua mākou i nā hiʻohiʻona ʻē aʻe o ka chip TU116 i ka hoʻohālikelike ʻana me nā ʻelele piha piha o ka ʻohana Turing (TU106, TU104 a me TU102) i ka loiloi o ka GeForce GTX 1660 Ti, akā pono ke nānā aku i nā hiʻohiʻona nui e hana ai i ka. ʻO TU116 e like me kāna mau analogues kahiko a i ʻole, e huki i waena o lākou i kahi palena ʻole. Ma ka huina holoʻokoʻa, hōʻike ka TU116 i nā hana hou a NVIDIA i hoʻokō ai i ka hale hoʻolālā Turing, koe naʻe nā cores e hana ana iā Ray Tracing a me nā cores tensor e hana ana i nā helu FMA (Fused-Multiply Add) ma ka hapalua-precision real matrices (FP16). ). Hoʻohana mua ʻia ka mea hope i nā hana aʻo mīkini, ke hele ka GPU i ka ʻikepili ma o kahi neural network i hana mua ʻia ma ka ʻāina a i ʻole ma kahi mahiʻai mamao. No laila, ua nalowale ka GeForce GTX 1660 a me GTX 1660 Ti i ka manawa like me ka DXR (Direct3D 12 extension for ray tracing) a me ka ʻenehana DLSS, kahi e hiki ai i ka GPU ke hāʻawi i kahi hoʻonā haʻahaʻa me ka scaling frame ma hope o ka hoʻohana ʻana i kahi neural network.
Ma kahi o nā ʻāpana tensor, ua hoʻolako ʻo NVIDIA i ka TU116 me kahi ʻāpana ʻokoʻa o nā cores CUDA 16-bit - ʻaʻole wikiwiki lākou e holo pono i ka DLSS, akā aia nā pāʻani e hoʻohana ana i nā hana hapalua i ka helu shader (no ka laʻana, Wolfenstein II. : ʻO ka New Colossus), no ka mea e hoʻonui nui ai ka hana o nā GPU kūpono (ʻo Vega a me Turing chips i kēia manawa). A i ʻole, ʻokoʻa ka TU116 mai nā ʻāpana kahiko o kona ʻohana ma ke ʻano quantitative wale nō, loaʻa iā ia nā pipeline optimizations āpau i loko o ka hale Turing, a kākoʻo i nā hana hoʻoili waiwai e like me VRS (Variable Rate Shading).
