Hōʻike ʻia ke kiʻi kiʻi kiʻi kiʻi kiʻi AMD Navi PCB he 256-bit bus a me GDDR6

Ua hoʻonohonoho koke ʻia ʻo AMD e hoʻolauna i kāna mau kiʻi kiʻi kiʻi Navi e hiki mai ana no nā kāleka kiʻi Radeon, e kuhikuhi ʻia i nā PC pāʻani pāʻani. ʻOiai ʻo ka hoʻolaha ʻana i hoʻonohonoho ʻia no Mei 27, ua ʻike ʻia ke kiʻi mua o ka papa o ka kāleka wikiō AMD Radeon RX e pili ana i ka hoʻolālā Navi ma ka Pūnaewele. Me he mea lā he hopena waena a i ʻole ka hopena kiʻekiʻe, no ka mea, hōʻike ka PCB i ka hoʻohana ʻana i kahi pahi 256-bit a me ka hoʻomanaʻo GDDR6. ʻIke ʻia, ke kamaʻilio nei mākou e pili ana i kahi kāleka wikiō 7nm, i manaʻo ʻia e lilo i hope maoli no ka Radeon RX 480.

Inā ʻoe e nānā pono i nā kikoʻī, hiki iā ʻoe ke ʻike i nā pad BGA (ball grid array) i hoʻomākaukau ʻia no ke kūʻai ʻana i ka chip GPU nui a me ka hoʻomanaʻo wikiō. ʻO ka mea pōʻino, ʻaʻole hiki ke haʻi maopopo i ke ʻano o ke aniani a mākou e kamaʻilio nei, akā he hopena maikaʻi loa ia. ʻEwalu BGA no nā pahu hoʻomanaʻo e ʻike ʻia a puni ka footprint GPU. ʻO ka helu o nā pine ma BGA no nā pahu hoʻomanaʻo he 180, no laila ke kamaʻilio nei mākou no GDDR6. No laila, ʻo kahi accelerator me kēia PCB ka huahana AMD Radeon mua e hoʻohana iā GDDR6.

Hōʻike pū nā pine hoʻomanaʻo wikiō 8 i ka bandwidth 256-bit. Malia paha e hoʻonoho ʻia ke kāleka ma ke ʻano he mea hoʻokūkū no ka NVIDIA GeForce RTX 2070, nona hoʻi kahi pahi 256-bit a me 8 GB o ka hoʻomanaʻo wikiō GDDR6. ʻO ka ʻaoʻao mua wale nō o ka papa kaapuni paʻi i loaʻa nā pilina BGA no nā pahu hoʻomanaʻo, no laila e kaupalena ʻia ka wikiwiki i ka 8 GB o ka hoʻomanaʻo wikiō.

Ma nā ʻōlelo o ka mana, kākoʻo ke kāleka i ka 8-phase VRM a hāʻawi ʻia ka mana ma o ʻelua mau slot PCIe. Hōʻike nā pine i ka hiki ke hoʻokomo i ʻelua mau mea hoʻohui 8-pin, akā hiki i nā mea hana ke hoʻohana iā lākou no nā mea hoʻohui 6-pin. Hiki paha i kēia ke ʻano mua loa o ka PCB no ka AMD accelerator e hiki mai ana, hiki ke loli.

Ua ʻike ʻia e kākoʻo ʻo AMD Navi i ka ray tracing (kekahi o nā hiʻohiʻona nui nā ʻoliʻoli o ka hanauna hou mai Sony). Ua hōʻike pū ʻia e loaʻa i nā kāleka wikiō me ka hoʻolālā Navi ke kākoʻo Kūlike Laea Kālā. ʻO kēia ʻenehana kahi analogue o NVIDIA Adaptive Shading a ua hoʻolālā ʻia e mālama i nā kumuwaiwai kāleka wikiō. Hāʻawi ia iā ʻoe e hōʻemi i ka ukana i ka helu ʻana i nā mea peripheral a me nā ʻāpana ma ka hōʻemi ʻana i ka pololei o nā helu.

ʻO ka hoʻolaha kūkala o nā kāleka kiʻi 7nm Navi a me nā kaʻina hana 7nm Ryzen 3000 i manaʻo ʻia ma Mei 27 ma kahi hōʻike kūikawā ma ka hanana Computex 2019, e mālama ʻia e AMD CEO Lisa Su.
