Ma ka liʻiliʻi, ke hōʻike ʻia nei nā kikoʻī hou aʻe e pili ana i ka hoʻolālā hou o AMD Navi GPUs. E like me kāu e ʻike ai, e lilo ʻo ia ka hoʻohana lōʻihi ʻia ʻo Graphics Core Next (GCN), akā i ka manawa like, e like me ka ʻikepili hou loa, e loaʻa iā ia nā loli nui loa. ʻO ka mea kūikawā, e hoʻoponopono ka hale hana hou i kahi drawback koʻikoʻi i loaʻa i nā mana o mua o GCN.
Aia ma ka Pūnaewele schematic diagram o ka Navi 10 GPU. I ka hoʻoholo ʻana ma ia mea, e māhele ʻia ka mana computing o ka GPU i ʻewalu shader units (Shader engine), kēlā me kēia mea e loaʻa i nā ʻāpana helu ʻelima (CU). E hoʻomanaʻo i kēlā me kēia CU i loko o ka hale hoʻolālā GCN he 64 kaʻina kahawai. ʻO ia hoʻi, e loaʻa ka huina o 10 stream processors ma Navi 2560. Maikaʻi no ka chip mid-range.
ʻO nā mana mua o ka hoʻolālā GCN e hoʻokaʻawale i nā ʻāpana helu i ʻehā mau ʻāpana shader. ʻO kēia hoʻonohonoho, no ka laʻana, i loko o ka Hawaii Pro chip me nā kaʻina kahawai 2560 like, a ua mau ia i nā Polaris a me Vega GPU. A ʻo ia ke kumu i hiki ʻole ai i nā AMD GPU ke hāʻawi aku ma mua o 64 ROP.
No laila, ʻo ka hoʻoholo e hoʻokaʻawale iā Navi GPU i ʻewalu shader ʻāpana e hāʻawi i ka manaolana no ka pālua ʻana o ka helu o nā ʻāpana hana raster, ʻo ia hoʻi, aia he 128 o lākou. ʻO kēia, ʻoiaʻiʻo, pono ka hopena maikaʻi i ka hana GPU, ʻoi loa i nā pāʻani.
