重點簡單翻譯整理,或有遺漏,建議英聽夠好的人自己看
(1)VRAM pin數看來為GDDR6。共8顆,最多256-bit。由頻寬可約略窺探效能,NV家也用
DDR6 256-bit的是2070、2080,但照過往經驗,同級A家顯卡常常用上更多頻寬。總之2080
很可能就是Navi的上限了
(2)雙8pin & 8+3相VRM(GPU+VRAM),VRM使用Smart Power Stage(SPS)模組。上次AMD在
公版卡用上這模組時是用70A的,這次一樣用70A的機率不低,AMD很愛對公版卡下過多的功
夫。但不能忽略它採用了那麼多相,是有比Radeon 7少,不過跟2080一樣,且2080只用
6+8pin。影片中假設8+8pin全用上,粗估功耗在250~300W,上限設300是因為超過就會跟
GTX480一樣淪為笑話。btw可能會從PCIE引電。
(3)極度有可能是渦輪散熱器,安裝孔都留好了。影片對此表示AMD你認真嗎?按理說沒
250W就用不到雙8pin的PCB,要是有250W還用渦輪散熱器……。
(4)有些莫名的開關,希望是因為ES要用到的而不是為了RGB。
