Isithombe esiputshuziwe sekhadi lemifanekiso le-PCB le-AMD Navi sibonisa ibhasi elingu-256-bit kanye ne-GDDR6

I-AMD maduze izokwethula izisheshisi zezithombe ze-Navi zesizukulwane esilandelayo samakhadi ezithombe ze-Radeon, azoqondiswe kuma-PC wokudlala wedeskithophu. Naphezu kweqiniso lokuthi isimemezelo sihlelelwe uMeyi 27, isithombe sokuqala sebhodi lekhadi levidiyo le-AMD Radeon RX lesikhathi esizayo elisekelwe ekwakhiweni kwe-Navi sivele ku-inthanethi. Kubukeka sengathi lesi yisixazululo esimaphakathi noma esisezingeni eliphezulu, ngoba i-PCB ikhombisa ukusetshenziswa kwebhasi le-256-bit kanye nenkumbulo ye-GDDR6. Ngokusobala, sikhuluma ngekhadi levidiyo le-7nm, okuhloswe ngalo ukuba ngumlandeli wangempela weRadeon RX 480.

Uma ubhekisisa imininingwane, ungabona amaphedi e-BGA (uhlu lwegridi yebhola) elungisiwe ukuze kuhlanganiswe i-chip ye-GPU eyinhloko nememori yevidiyo. Ngeshwa, akunakwenzeka ukusho ngokuqinisekile ukuthi hlobo luni lwekristalu esikhuluma ngalo, kodwa mhlawumbe kuzoba yisixazululo esikhiqiza kakhulu. Ama-BGA ayisishiyagalombili ama-memory chips ayabonakala eduze kwe-GPU footprint. Inombolo yezikhonkwane nge-BGA ngayinye yama-memory chips yi-180, ngakho-ke sikhuluma nge-GDDR6. Ngakho-ke, i-accelerator enale PCB izoba umkhiqizo wokuqala we-AMD Radeon ukusebenzisa i-GDDR6.

Izikhonkwane ezingu-8 zememori yevidiyo nazo zibonisa umkhawulokudonsa wamabhithi angu-256. Mhlawumbe ikhadi lizobekwa njengesimbangi ku-NVIDIA GeForce RTX 2070, nayo enebhasi engu-256-bit kanye ne-8 GB yememori yevidiyo ye-GDDR6. Uhlangothi olungaphambili kuphela lwebhodi lesifunda eliphrintiwe olunabathintwayo be-BGA kuma-memory chips, ngakho-ke i-accelerator cishe izokhawulelwa ku-8 GB yememori yevidiyo.

Ngokwamandla, ikhadi lisekela i-VRM yesigaba esingu-8 futhi amandla anikezwa ngezikhala ezimbili ze-PCIe. Izikhonkwane zibonisa ukuthi kungenzeka ukufaka izixhumi ezimbili ezingu-8, kodwa abakhiqizi bangazisebenzisa izixhumi ezingu-6-pin. Kungenzeka ukuthi lena inguqulo yangaphambi kwesikhathi ye-PCB yesisheshisi se-AMD esizayo, esingase sishintshe.

Kuyaziwa ukuthi i-AMD Navi izokweseka ukulandelwa kwe-ray (esinye sezici ezibalulekile isizukulwane esilandelayo siduduza kwaSony). Kuphinde kwabikwa ukuthi amakhadi evidiyo anesakhiwo se-Navi azothola ukwesekwa Ukushintshanisa Ngezilinganiso Okuguquguqukayo. Lobu buchwepheshe buyi-analogue ye-NVIDIA Adaptive Shading futhi yakhelwe ukulondoloza izinsiza zekhadi levidiyo. Ikuvumela ukuthi unciphise umthwalo lapho ubala izinto ze-peripheral kanye nezindawo ngokunciphisa ukunemba kwezibalo.

Isimemezelo esisemthethweni samakhadi emifanekiso e-7nm Navi kanye nama-processor we-7nm Ryzen 3000 kulindeleke ngoMeyi 27 ekwethulweni okukhethekile emcimbini weComputex 2019, ozobe ubanjwe yi-CEO ye-AMD uLisa Su.
