AMD tsis ntev los no tau npaj los qhia txog nws cov Navi tiam tom ntej cov duab nrawm rau Radeon cov duab kos, uas yuav raug tsom rau cov duab gaming PCs. Txawm hais tias qhov kev tshaj tawm tau teem tseg rau lub Tsib Hlis 27, thawj daim duab ntawm pawg thawj coj saib yav tom ntej AMD Radeon RX video card raws li Navi architecture tau tshwm sim hauv Is Taws Nem. Nws zoo li qhov no yog qhov nruab nrab lossis txawm tias qhov kev daws teeb meem siab, vim tias PCB qhia txog kev siv lub npav 256-ntsis thiab GDDR6 nco. Thaj, peb tab tom tham txog 7nm daim npav video, uas yog npaj los ua tus ua tiav tiag tiag rau Radeon RX 480.
Yog tias koj saib ze ntawm cov ntsiab lus, koj tuaj yeem pom npaj BGA (pob daim phiaj array) pads rau soldering lub ntsiab GPU chip thiab video nco. Hmoov tsis zoo, nws tsis tuaj yeem hais kom paub tseeb tias peb tab tom tham txog dab tsi, tab sis nws yuav yog ib qho kev daws teeb meem zoo heev. Yim BGAs rau nco chips pom nyob ib ncig ntawm GPU hneev taw. Tus naj npawb ntawm tus pins ib BGA rau lub cim xeeb chips yog 180, yog li peb tab tom tham txog GDDR6. Yog li, tus accelerator nrog PCB no yuav yog thawj AMD Radeon cov khoom siv GDDR6.
Lub 8 video nco pins kuj qhia 256-ntsis bandwidth. Tej zaum daim npav yuav raug muab tso ua tus neeg sib tw rau NVIDIA GeForce RTX 2070, uas tseem muaj 256-ntsis npav thiab 8 GB ntawm GDDR6 video nco. Tsuas yog sab pem hauv ntej ntawm lub rooj tsavxwm luam tawm muaj BGA hu rau lub cim xeeb chips, yog li lub accelerator tej zaum yuav raug txwv rau 8 GB ntawm lub cim xeeb video.
Hais txog lub zog, daim npav txhawb nqa 8-theem VRM thiab lub zog tau muab los ntawm ob lub PCIe qhov. Cov pins qhia txog qhov muaj peev xwm ntawm kev txhim kho ob lub 8-pin connectors, tab sis cov tuam ntxhab tuaj yeem siv lawv rau 6-pin connectors. Nws yog tau hais tias qhov no yog ib tug ncaj ncees version ntawm PCB rau yav tom ntej AMD accelerator, uas tej zaum yuav tseem hloov.
Nws paub tias AMD Navi yuav txhawb txoj kab hluav taws xob (ib qho ntawm cov yam ntxwv tseem ceeb ). Nws kuj tau tshaj tawm tias daim npav video nrog Navi architecture yuav tau txais kev txhawb nqa . Cov thev naus laus zis no yog ib qho analogue ntawm NVIDIA Adaptive Shading thiab yog tsim los txuag cov peev txheej video. Nws tso cai rau koj kom txo tau cov load thaum xam cov khoom peripheral thiab ib cheeb tsam los ntawm kev txo qhov tseeb ntawm kev suav.
Cov ntawv tshaj tawm raug cai ntawm 7nm Navi graphics phaib thiab 7nm Ryzen 3000 processors yuav tsum nyob rau lub Tsib Hlis 27 ntawm kev nthuav qhia tshwj xeeb ntawm Computex 2019 qhov kev tshwm sim, uas yuav muaj los ntawm AMD CEO Lisa Su.
