Ihe onyonyo PCB kaadị AMD Navi agbagoro na-egosi ụgbọ ala 256-bit na GDDR6

N'oge na-adịghị anya AMD ga-ewebata ndị na-eme ihe ngosi eserese Navi nke na-esote maka kaadị eserese Radeon, nke a ga-ezubere na PC egwuregwu desktọpụ. N'agbanyeghị na a na-ahazi ọkwa ahụ maka May 27, ihe oyiyi mbụ nke bọọdụ nke kaadị vidiyo AMD Radeon RX n'ọdịnihu dabere na ụkpụrụ ụlọ Navi pụtara na ịntanetị. Ọ dị ka nke a bụ ihe ngwọta dị n'etiti ma ọ bụ ọbụna njedebe dị elu, n'ihi na PCB na-egosi iji bọs 256-bit na ebe nchekwa GDDR6. N'ụzọ doro anya, anyị na-ekwu maka kaadị vidiyo 7nm, nke ezubere ka ọ bụrụ ezigbo onye ga-anọchi anya Radeon RX 480.

Ọ bụrụ n’ileba anya na nkọwapụta nke ọma, ị ga-ahụ paịlị BGA (bọọlụ grid array) akwadoro maka ịgbanye mgbawa GPU isi na ebe nchekwa vidiyo. N'ụzọ dị mwute, ọ gaghị ekwe omume ikwu n'ezie ụdị kristal anyị na-ekwu maka ya, mana ọ ga-abụ ihe ngwọta na-arụpụta ihe. A na-ahụ BGA asatọ maka ibe ebe nchekwa gburugburu akara ukwu GPU. Ọnụ ọgụgụ nke ntụtụ kwa BGA maka ibe ebe nchekwa bụ 180, yabụ anyị na-ekwu maka GDDR6. Ya mere, onye na-eme ngwangwa nwere PCB a ga-abụ ngwaahịa AMD Radeon mbụ iji GDDR6.

Ntụtụ 8 maka ebe nchekwa vidiyo na-egosikwa bandwit 256-bit. Ikekwe, a ga-edobe kaadị ahụ dị ka onye asọmpi na NVIDIA GeForce RTX 2070, nke nwekwara ụgbọ ala 256-bit na 8 GB nke ebe nchekwa vidiyo GDDR6. Naanị akụkụ ihu nke bọọdụ sekit e biri ebi nwere kọntaktị BGA maka ibe ebe nchekwa, yabụ enwere ike ịnwe ngwa ngwa na 8 GB nke ebe nchekwa vidiyo.

N'ihe gbasara ike, kaadị ahụ na-akwado 8-phase VRM ma na-enye ike site na oghere PCIe abụọ. Ntụtụ ndị ahụ na-egosi ohere nke ịwụnye njikọ abụọ 8-pin, mana ndị nrụpụta nwere ike iji ha maka njikọ 6-pin. O kwere omume na nke a bụ ụdị mbụ nke PCB maka ngwa ngwa AMD n'ọdịnihu, nke ka nwere ike ịgbanwe.

A maara na AMD Navi ga-akwado tracing ray (otu n'ime isi njirimara ọgbọ ọzọ consoles si Sony). A kọkwara na kaadị vidiyo nwere ụlọ ọrụ Navi ga-enweta nkwado Mgbanwe ọnụego Shading. Teknụzụ a bụ analog nke NVIDIA Adaptive Shading ma emebere ya iji chekwaa akụrụngwa kaadị vidiyo. Ọ na-enye gị ohere ibelata ibu mgbe ị na-agbakọ ihe ndị dị n'akụkụ na mpaghara site na ibelata izi ezi nke ngụkọta oge.

A na-atụ anya ọkwa ọkwa nke kaadị eserese 7nm Navi na 7nm Ryzen 3000 na Mee 27 na ngosi pụrụ iche na mmemme Computex 2019, nke AMD CEO Lisa Su ga-eme.
