Chithunzi chotsikitsitsa cha khadi la PCB cha AMD Navi chikuwonetsa basi ya 256-bit ndi GDDR6

AMD yatsala pang'ono kubweretsa zida zake za Navi graphics accelerators za makadi ojambula a Radeon, omwe azikhala ndi ma PC amasewera apakompyuta. Ngakhale kuti chilengezochi chikukonzekera pa Meyi 27, chithunzi choyamba cha khadi ya kanema ya AMD Radeon RX yamtsogolo yotengera kapangidwe ka Navi chawonekera pa intaneti. Zikuwoneka ngati iyi ndi njira yapakatikati kapena yomaliza, chifukwa PCB ikuwonetsa kugwiritsa ntchito basi ya 256-bit ndi kukumbukira kwa GDDR6. Mwachiwonekere, tikukamba za khadi la kanema la 7nm, lomwe cholinga chake ndi kukhala wolowa m'malo weniweni wa Radeon RX 480.

Mukayang'anitsitsa mwatsatanetsatane, mutha kuwona zokonzekera za BGA (magulu amtundu wa mpira) zogulitsira chipangizo chachikulu cha GPU ndi kukumbukira kwamakanema. Tsoka ilo, ndizosatheka kunena motsimikiza kuti ndi mtundu wanji wa kristalo womwe tikukamba, koma mwina ungakhale yankho lopindulitsa kwambiri. Ma BGA asanu ndi atatu a kukumbukira tchipisi amawoneka mozungulira ma GPU. Chiwerengero cha mapini pa BGA ya tchipisi tokumbukira ndi 180, ndiye tikukamba za GDDR6. Chifukwa chake, chothamangitsira chokhala ndi PCB iyi chidzakhala chida choyamba cha AMD Radeon kugwiritsa ntchito GDDR6.

Ma pini 8 a kukumbukira kanema amawonetsanso 256-bit bandwidth. Mwina khadiyo idzayikidwa ngati mpikisano ku NVIDIA GeForce RTX 2070, yomwe ilinso ndi basi ya 256-bit ndi 8 GB ya kukumbukira mavidiyo a GDDR6. Ndi mbali yakutsogolo yokha ya bolodi yosindikizidwa yomwe ili ndi ma BGA olumikizirana ndi ma memory chips, chifukwa chake chowonjezeracho chingakhale chochepera 8 GB ya kukumbukira kwamakanema.

Pankhani ya mphamvu, khadiyo imathandizira 8-gawo VRM ndipo mphamvu imaperekedwa kudzera pamipata iwiri ya PCIe. Zikhomo zikuwonetsa kuthekera kokhazikitsa zolumikizira ziwiri za 8-pini, koma opanga amatha kuzigwiritsa ntchito pazolumikizira 6-pini. Ndizotheka kuti iyi ndi mtundu woyambirira wa PCB wamtsogolo wa AMD accelerator, womwe ungasinthebe.

Zimadziwika kuti AMD Navi ithandizira kufufuza kwa ray (chimodzi mwazinthu zofunika kwambiri kutonthoza m'badwo wotsatira kuchokera ku Sony). Zinanenedwanso kuti makadi amakanema omwe ali ndi zomangamanga za Navi adzalandira chithandizo Mtundu Wosintha. Ukadaulowu ndi wofanana ndi NVIDIA Adaptive Shading ndipo wapangidwa kuti usunge zothandizira makadi amakanema. Zimakuthandizani kuti muchepetse katundu powerengera zinthu zam'mbali ndi zigawo pochepetsa kulondola kwa mawerengedwe.

Chilengezo chovomerezeka cha makadi ojambula a 7nm Navi ndi mapurosesa a 7nm Ryzen 3000 akuyembekezeka pa Meyi 27 pamsonkhano wapadera pamwambo wa Computex 2019, womwe udzachitike ndi CEO wa AMD Lisa Su.
